This work aimed to incorporate the active compounds of the jambolan leaf in sunflower seed oil, in order to increase the nutritional quality of the oil. For this purpose, ultrasound-assisted extraction was conducted to establish the process conditions related to temperature, potency, solvent:sample ratio and time to obtain the enriched sunflower seed oil (ESSO). An experimental design was applied to examine the effect of variables (temperature, power, solvent:sample ratio and time) on the extraction mass yield (EMY). The application of maximum temperature, increased power, sample:solvent ratio and time resulted in higher EMY. Maximum theoretical EMY value was 35.16% (60 °C, 100%, 1:12 g mL-1 and 15 min). The characterization of the oils obtained from ESSO and sunflower seed oil (SSO) verified a higher content of flavonoids, phenolic compounds, a large proportion of active compounds, antioxidant activity, content of phytosterols, α-tocopherol and squalene, and induction time for ESSO. purpose ultrasoundassisted ultrasound assisted temperature potency solventsample solvent sample .

RESUMO: O melão de polpa alaranjada honeydew apresenta elevado potencial nutricional e econômico, sendo amplamente apreciado como fruta doce e refrescante. Portanto, avaliar amostras comerciais de produtos tão relevantes para o mercado de frutas frescas é de grande importância. O objetivo deste estudo foi investigar a capacidade antioxidante, os parâmetros de qualidade e a composição química de melões do mercado brasileiro. Os valores de pH e ºBrix determinados para as amostras de melão foram 6,5 ± 0,30 e 9,2 ± 0,80 g/100 g (peso fresco), respectivamente, o que está de acordo com os resultados esperados para melões de alta qualidade. A análise cromatográfica revelou a sacarose (49% do açúcar total) como principal açúcar, seguida pela frutose (30%) e glicose (21%). Os carotenóides, que estão diretamente ligados à cor laranja característica, apresentaram teor total de 270,59 µg/g (peso seco). Além disso, o maior valor de b* comparado ao valor de a* indica a maior contribuição da cor amarela. Quanto ao potencial antioxidante, além de apresentar capacidade antioxidante para ambos os métodos aplicados, DPPH e FRAP, níveis variando de 16,40 ± 0,21 µmol equivalente de ácido ascórbico/g a 56,98 ± 0,80 µmol equivalente de Trolox/g (peso seco) foram encontrados nos extratos de melão. Ademais, os resultados foram maiores em termos de FRAP do que em DPPH. Desta forma, os resultados destacam os melões avaliados como fontes valiosas de compostos bioativos, como carotenóides e fenólicos, que contribuem para suas propriedades antioxidantes. Além disso, análises de cor, pH e teor de sólidos solúveis totais também refletem os atributos de qualidade.

ABSTRACT: Orange-fleshed non-netted honeydew melon has high nutritional and economic potential, being widely appreciated as a refreshing sweet fruit. Therefore, evaluating commercial samples of such relevant products for the fresh fruit market is of great importance. This study investigated the antioxidant capacity, quality parameters, and chemical composition of honeydew melons from the Brazilian market. The values of pH and °Brix determined for melon samples were 6.5 ± 0.30 and 9.2 ± 0.80 g/100 g (fresh weight), respectively, which agree with the results expected for high-quality melons. The chromatography analysis revealed sucrose (49% of total sugar) as the main sugar, followed by fructose (30%) and glucose (21%). Carotenoids, which are directly linked to the characteristic orange color, showed a total level of 270.59 µg/g (dry weight). Additionally, the higher b* value compared to a* value indicates the highest yellow contribution. Regarding the antioxidant assays, in addition to presenting antioxidant capacity for both methods applied, DPPH and FRAP, levels ranging from 16.40 ± 0.21 µmol ascorbic acid equivalent/g to 56.98 ± 0.80 µmol Trolox equivalent/g (dry weight) were reported in melon extracts. Moreover, the results were higher in terms of FRAP than DPPH. Therefore, the results underscore the evaluated honeydew melons as valuable sources of bioactive compounds, such as carotenoids and phenolics, which contribute to their antioxidant properties. Besides, analyses of color, pH, and total soluble solids content also reflect the quality attributes.

ABSTRACT: To improve the nutritional and functional quality of agro-industrial waste, his study established a ternary mixture of flours made from pineapple, acerola, and passion fruit waste using the simplex-centroid design, as well as to evaluate their effects on the physicochemical and sensory characteristics of edible ice cream. Using mixture planning, nine ternary flour components were applied to edible ice cream formulations to evaluate acceptance scores for taste, texture, and overall impression attributes, as well as physicochemical parameters (pH, acidity, soluble solids, and color parameters) and microbiological parameters (thermotolerant coliforms at 45 ºC, Enterobacteriaceae and Salmonella). The simplex-centroid design demonstrated that the cubic model best predicts the results for the analyzed sensory attributes. The response surface graphs indicated the area of greatest acceptance in the formulations with the maximum percentage established for the flour with acerola waste. The highest level of acceptability was given to the ternary mixture of 60%, 30%, and 10% pineapple, passion fruit, and acerola flours, respectively. The results indicated that sorbet enriched with flour composed of the ternary mixture is a product with the potential for exploitation, as well as contributing to the reduction of environmental impacts generated by the large and improper disposal of agro-industrial fruit processing residues in the ecosystem.

ABSTRACT Beans are a vital component of the human diet, being able to supply a large part of the daily protein requirements of individuals, in addition to containing considerable amounts of iron, calcium, vitamins, carbohydrates, fiber, and lysine. Controlled germination is an accessible and effective technique that aims to improve the nutritional, functional, and sensory qualities of seeds intended for food consumption. This study aimed to characterize fresh and germinated beans of Phaseolus vulgaris (carioca, branco, preto, gordo varieties) and Vigna unguiculata (cowpea). The germination process was conducted in trays containing the sand substrate (350 g) in the environmental conditions of the laboratory. The fresh and germinated beans were evaluated for physicochemical variables in triplicate. The germination process increased moisture content, water activity, ash, pH, soluble alcohol acidity, proteins, ascorbic acid, phenols, tannins, flavonoids, anthocyanins, and carotenoids. On the other hand, there was a reduction in the content of lipids, starch, and total sugars in bean seeds. With the increase in bioactive compounds, it was found that the germination process is an excellent method for increasing the nutritional quality of beans. diet individuals iron calcium vitamins carbohydrates fiber lysine functional consumption carioca, carioca (carioca branco preto varieties cowpea. cowpea .

Abstract Introduction. In organic agriculture, green manures and biocontrols are used as methods for fertilization and pest control. However, their independent application of these inputs increases production costs. A pelletized formulation is proposed to allow simultaneous application of both inputs. Objective. To evaluate the effect of pelletized Mucuna pruriens (L.) DC. inoculated with Trichoderma harzianum Rifai on nutritional intake, agricultural yield, and regulation of Fusarium oxysporum f. sp. lycopersici in tomato (Solanum lycopersicum L.). Materials and methods. The experiment was carried out in 2022 in Tablón del Guarco, Cartago, Costa Rica, using a randomized complete block design with seven treatments and seven repetitions. Two formulations (A and B) of biopellet (M. pruriens + zeolite + T. harzianum) were applied at three dosages (15, 30, 50 g/plant). T. harzianum was added at a rate of 5 g/kg of biopellet. Applications of each treatment were conducted every 15 days for a total of eight applications. At the time of planting, F. oxysporum was inoculated (100 mL/plant with a concentration of 1 x 103 CFU). Results. The application of biopellet achieved a yield and weight of high-quality fruits similar to the commercial control. There were no significant differences among treatments for second and third-quality fruits. The technical efficiency in controlling F. oxysporum reached 97.6 % with biopellet. This amendment increased the levels of Carbon (C), Nitrogen (N), and organic matter in the soil and affected the nutritional content of the plant foliage in the first 60 days after sowing. Conclusions. The biopellet has the capacity to make chemical and organic contributions to the soil, which improves the nutrition of the tomato crop. It could be also a biocontrol alternative against F. oxysporum and compatible with T. harzianum.

Abstract Introduction: The malnutrition-inflammation process is one of the main causes of morbidity and mortality in patients with chronic kidney disease (CKD), influencing quality of life. The aim of this study was to identify the inflammatory and nutritional status of elderly hemodialysis (HD) and its association with quality of life. Methods: This study was carried out in health services in three different cities. The Malnutrition-Inflammation Score (MIS) was used to assess the inflammatory and nutritional status, with anthropometric measurements, protein status, lean mass and function. The quality of life was assessed using KDQOL-SFTM. Data were analyzed using multivariate analysis and the Poisson model to evaluate the factors that increased the risk of developing malnutrition and inflammation. Results: The MIS identified a 52.2% prevalence of malnutrition and inflammation in the population. In univariate analysis, most KDQOL-SFTM domains presented higher scores for nourished elderly. Anthropometric measures associated with muscle mass and functionality were lower in the malnourished elderly. Multivariate modeling revealed a higher nutritional risk of 50.6% for women and older age, since with each additional year of life the risk of malnutrition increased by 2.4% and by 0.4% with each additional month on HD. Greater arm muscle circumference (AMC) and higher serum albumin were factors for reducing malnutrition by 4.6% and 34.7%, respectively. Conclusion: Higher serum albumin and preserved AMC have been shown to be good indicators of better nutritional status. Higher MIS was associated with poorer quality of life, older age, lower income and education, longer time on dialysis, and presence of comorbidities.

Resumo Introdução: O processo de desnutrição-inflamação é uma das principais causas de morbimortalidade em pacientes com DRC, influenciando a qualidade de vida. O objetivo deste estudo foi identificar o estado inflamatório e nutricional de idosos em hemodiálise (HD) e sua associação com qualidade de vida. Métodos: Estudo realizado em serviços de saúde de três cidades diferentes. O Escore de Desnutrição-Inflamação (MIS, por sua sigla em inglês) foi utilizado para avaliar estado inflamatório e nutricional, com medidas antropométricas, estado proteico, massa magra e funcionalidade. A qualidade de vida foi avaliada com KDQOL-SFTM. Os dados foram analisados utilizando análise multivariada e modelo de Poisson para avaliar fatores que aumentaram o risco de desenvolver desnutrição e inflamação. Resultados: O MIS identificou prevalência de 52,2% de desnutrição e inflamação na população. Na análise univariada, a maioria dos domínios do KDQOL-SFTM apresentou escores maiores para idosos nutridos. Medidas antropométricas associadas à massa muscular e funcionalidade foram menores em idosos desnutridos. A modelagem multivariada revelou maior risco nutricional de 50,6% para mulheres e idosos pois o risco de desnutrição aumentou em 2,4% para cada ano adicional de vida e em 0,4% para cada mês adicional de HD. Maior circunferência muscular do braço (CMB) e maior albumina sérica foram fatores de redução da desnutrição em 4,6% e 34,7%, respectivamente. Conclusão: Demonstrou-se que albumina sérica mais elevada e CMB preservada são bons indicadores de melhor estado nutricional. Maior MIS foi associado a pior qualidade de vida, idade mais avançada, menor renda e escolaridade, maior tempo em diálise e presença de comorbidades.

Abstract Introduction: Reservoirs are conceived as a set of interactions in which physical, chemical, and biological instability determines changes in the density of planktonic communities. Objective: To evaluate the instability of phytoplankton and zooplankton, and their interactions with environmental factors in four tropical Andean reservoirs with different trophic status. Methods: Physical and chemical variables and phytoplankton and zooplankton densities were measured between 2010-2018 in the oligotrophic reservoirs Punchiná and San Lorenzo and between 2013 and 2015 in the hypereutrophic reservoir Porce II and in the eutrophic Porce III reservoir (total N = 248). The Factor Shaping Community Assemblages (FCA) was used to calculate environmental and biotic instability as well as their interaction. Results: High environmental and biological instability was observed in the studied reservoirs. Oxygen saturation, pH, total nitrogen, water temperature, nitrites, total phosphorus (only for zooplankton), and total solids were the abiotic variables with the greatest contribution to planktonic instability, regardless of trophic state. Particularly, Cryptomonas sp., Aulacoseira sp., Cyclotella sp., Dinobryon sp., Nephrocytium sp., Tetraëdron caudatum and Oscillatoria sp. had the greatest influence on the instability of various rotifer taxa and some copepods. Conclusions: Regardless of trophic state, pH dynamics, nutrients availability, amount of suspended solids and the availability of gases, such as dissolved oxygen, mainly determined the instability of phytoplankton and to a lesser extent that of zooplankton. In the oligotrophic reservoirs, zooplankton instability was mainly influenced by highly palatable algae with no toxicity, and in reservoirs highly enriched, the instability was influenced by algae with low nutritional quality and difficult to ingest and manipulate.

Resumen Introducción: los embalses deben ser concebidos como un conjunto de interacciones, donde la inestabilidad física, química y biológica determinan cambios en la densidad de las comunidades planctónicas. Objetivo: Evaluar la inestabilidad del fitoplancton y zooplancton y su interacción con factores ambientales en cuatro embalses tropicales andinos con diferente estado trófico. Métodos: Se analizaron datos de variables físicas y químicas y de las densidades del fitoplancton y del zooplancton, medidas entre 2010-2018, en los embalses oligotróficos Punchiná y San Lorenzo y, entre 2013 y 2015, en el embalse hipereutrófico Porce II y en el embalse eutrófico Porce III (total N = 248). Se empleó el Factor Shaping Community Assemblages (FCA), para calcular la inestabilidad biótica y ambiental y la interacción entre estas. Resultados: En los embalses estudiados hubo una alta inestabilidad ambiental y biológica. El pH, la saturación de oxígeno, el nitrógeno total, la temperatura del agua, los nitritos, el fósforo total (solo para el zooplancton) y los sólidos totales, son las variables abióticas con mayor aporte a la inestabilidad planctónica, independientemente del estado trófico. Particularmente, Cryptomonas sp., Aulacoseira sp., Cyclotella sp., Dinobryon sp., Nephrocytium sp., Tetraëdron caudatum y Oscillatoria sp., tuvieron mayor influencia sobre la inestabilidad de diferentes taxones de rotíferos y de algunos copépodos. Conclusión: Independiente del estado trófico, la dinámica del pH, la disponibilidad de nutrientes, la cantidad de sólidos suspendidos y la disponibilidad de gases como el oxígeno disuelto determinaron principalmente la inestabilidad del fitoplancton, y en menor medida la del zooplancton. En los embalses oligotróficos la inestabilidad del zooplancton es influenciada principalmente por algas altamente apetecibles con toxicidad nula, y en embalses altamente enriquecidos la inestabilidad fue influenciada por algas con baja calidad nutricional y de difícil ingestión y manipulación.

SUMMARY OBJECTIVE: The aim of this study was to investigate the effect of different dietary inflammatory index diets on inflammatory markers, anthropometric measurements, and sleep quality in obese subjects. METHODS: This study was conducted in a public hospital in Turkey between November 2021 and May 2022. Participants with pro-inflammatory dietary habits were included in the study. Randomly divided into two groups of 33 participants, they were subjected to an anti-inflammatory diet or a control diet for 8 weeks. The study evaluated the anthropometric parameters, inflammatory biomarkers, and sleep quality indices of the diet groups. RESULTS: Significant reductions in body mass index were observed in both groups, more marked in the anti-inflammatory diet cohort. C-reactive protein levels, indicative of inflammation, also decreased substantially in both groups, with a more marked reduction in the anti-inflammatory diet cohort. Despite the improvement in sleep quality in both groups, the variation was not statistically significant. CONCLUSION: This study demonstrates the importance of anti-inflammatory diets in nutritional strategies for obesity by reducing body mass index and inflammation.

Abstract School-age children (5-9 years) can benefit from educational interventions focused on healthy eating and physical activity to improve their quality of life. This work aims to review the evidence on food and nutrition education (FNE) in Spanish-speaking countries for the prevention of overweight and obesity in school-age children. There is a wide variety of experiences in FNE in Hispanic countries. The FNE interventions are effective in improving knowledge and attitudes towards healthy eating. Diagnosis, variable selection, and the design and validation of interventions and instruments are crucial. The frequency, duration and number of components of the interventions, as well as the participation of multiple actors such as parents, teachers, professors, and the school community, are key to greater effectiveness. Little impact is observed on nutritional status in educational interventions, which may be due to short execution periods. Food and nutritional surveillance systems in schools should consider cognitive and behavioral indicators to measure the effectiveness of FNE in the fight against overweight and obesity in schools. In conclusion, greater effectiveness of FNE is observed in knowledge and attitudes. Teacher training programs are required to implement innovative long-term FNE strategies in schools to combat obesity and prevent chronic diseases early in life, as well as robust monitoring and evaluation systems.

Resumen Los niños de edad escolar (NEE) pueden beneficiarse de intervenciones educativas centradas en alimentación saludable y actividad física para mejorar su calidad de vida. Este trabajo tiene como objetivo revisar la evidencia sobre educación alimentaria y nutricional (EAN) en países de habla hispana para la prevención del sobrepeso y la obesidad en NEE. Existe una amplia variedad de experiencias en EAN en países hispanos. Las intervenciones son efectivas para mejorar conocimiento y actitud hacia la alimentación saludable. El diagnóstico, selección de variables a intervenir, el diseño de intervenciones y de instrumentos válidos son clave. La frecuencia, duración y el número de componentes de las intervenciones son clave para mayor efectividad en las intervenciones, así como la participación de múltiples actores como padres, maestros, profesores y la comunidad escolar. Se observa poco impacto sobre el estado nutricional en las intervenciones educativas. Sin embargo, esto puede deberse a cortos periodos de ejecución. Los sistemas de vigilancia alimentarios y nutricionales en las escuelas deben considerar indicadores cognitivos y conductuales para medir la eficacia de las intervenciones EAN en el marco de la lucha contra el sobrepeso y la obesidad en las escuelas. En conclusión, se observa una mayor efectividad de las intervenciones EAN en el conocimiento y la actitud. Se requieren programas de capacitación docente para implementar estrategias innovadoras de EAN en las escuelas de largo plazo para combatir la obesidad y prevenir las enfermedades crónicas desde temprano en la vida; así como de robustos sistemas de seguimiento y evaluación.

ABSTRACT Whey is a residue from the cheese industry whose use as a raw material in human food formulations has been studied, mainly due to its nutritional composition and the negative impact it has on the environment when discarded.

ABSTRACT Climatic conditions cause variation in the availability and nutritional quality of forages; therefore, the use of corn (Zea mays L.) silage has been proposed. However, this crop has a low protein concentration, so the combination with legumes can improve this characteristic. The objective of this study was to evaluate the nutritive value of silage in different proportions of soybean (Glycine max (L.) Merr.) and corn forage grown in a subtropical region. In Tamaulipas, Mexico, six treatments were evaluated: Soybean 100% (S100), corn 100% (C100), and soybean-corn proportions (80%-20%: S80C20; 60%-40%: S60C40; 40%-60%: S40C60, and 20%-80%: S20C80). The variables that were evaluated were: Density, pH, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin, non-fibrous carbohydrates (NFC), starch, crude fat, net energy for lactation (NEL), net energy for weight gain (NEG), and metabolizable energy (ME) and mineral content. Data were analyzed as a completely randomized design with three replicates per treatment. Treatment S100 showed the highest values (p < 0.05) in CP, ADF, crude fat, NEL, and NEG. The C100 had the highest values (p < 0.05) in starch and NFC, and the lowest pH value (p < 0.05). Meanwhile, the S40C60, S60C40, S20C80 combinations showed the highest values (p < 0.05) of TDN, ENL, and ENG. In the case of the combinations, the one with the best values was S40C60. In this regard, the mean values were: CP 143 g kg-1; NEL 1.43 Mcal kg-1; and pH 3.9. According to these values, it is classified as a silage of good nutritional quality, and we recommend its use in subtropical climates.

Abstract Introduction. Corn (Zea mays) is widely used in animal feed, either as grain, green fodder or silage. Objective. To evaluate the yield and nutritional quality of 6 Costa Rican corn varieties selected for grain production. Materials and methods. The study was conducted at 4 experimental sites (Aguas Zarcas, Turrialba, San Luis de Monteverde and Guápiles) between September and December 2018. At each site, a randomized complete block design with 4 replications and 8 treatments (6 varieties and 2 corn hybrids). Plant height was evaluated, Dry Mass (DM) production, chemical composition and in vitro DM digestibility at forage harvest were evaluated. Results. Plant height and DM production were affected by treatments. Yields of the Costa Rican DM varieties EJN2, Upiav-G6, Los Diamantes 8843 and JSáenz (12.7-14 t.ha-1) were similar to the forage hybrid CLTHY002 (13.5 t.ha-1). Only DM and CP content varied in the treatments. Conclusions. The Costa Rican corn varieties EJN2, Los Diamantes 8843, JSáenz and Upiav-G6, have potential to be used as a forage source for animal feeding because they achieved yields and nutritive values like those obtained with the hybrids selected by Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT) for forage production.

Resumen Introducción. El cultivo de maíz (Zea mays) es ampliamente utilizado en la alimentación animal, tanto en forma de grano, como forraje verde o ensilaje. Objetivo. Evaluar la producción y calidad nutritiva de 6 variedades de maíces costarricenses seleccionados para la producción de grano. Materiales y métodos. El estudio se realizó en 4 sitios experimentales (Aguas Zarcas, Turrialba, San Luis de Monteverde y Guápiles) entre setiembre y diciembre del 2018. En cada sitio, se trabajó con un diseño de bloques completos al azar con 4 repeticiones y 8 tratamientos (6 variedades y 2 híbridos de maíces). Se evaluó la altura de la planta, la producción de materia seca (MS), la composición química y la digestibilidad in vitro de la MS a la cosecha de los forrajes. Resultados. La altura de la planta y la producción de MS fueron afectadas por los tratamientos. Los rendimientos de MS de las variedades costarricenses EJN2, Upiav-G6, Los Diamantes 8843 y JSáenz (12,7-14 t.ha-1) fueron semejantes al híbrido forrajero CLTHY002 (13,5 t.ha-1). Solamente el contenido de MS y PC varío entre los tratamientos. Conclusión. Las variedades de maíces costarricenses EJN2, Los Diamantes 8843, JSáenz y Upiav-G6, tienen potencial para ser utilizadas como fuente forrajera para la alimentación de rumiantes, ya que alcanzaron rendimientos y valores nutritivos semejantes a los obtenidos con los híbridos seleccionados por el Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT) para la producción de forrajes.

ABSTRACT Due to the smaller size of berries plants and some vegetables, their production in containers has grown worldwide. To understand the effect of increasing doses of ammoniacal N, we evaluated production, firmness and size of fruits and concentration of macronutrients in leaves of four blueberry (Vaccinium corymbosum L.) cultivars (Duke, Legacy, Cargo, and Suziblue) in south central Chile. All were grown in pots with substrate during their third growing season. The results showed an interaction of ammoniacal N dose with blueberry cultivar in most of the parameters evaluated, except for firmness and size of fruits. The increasing dose of ammoniacal N allowed higher production per plant in only two of the four cultivars without effects on the quality attributes firmness and size of fruits. Differences in production per plant and fruit firmness were obtained between cultivars, with production values per plant between 86-210, 142-219, 195-203, and 504-979 g in ʻDukeʼ, ʻLegacyʼ, ʻCargoʼ, and ʻSuziblueʼ, respectively, and greater fruit firmness in ʻSuziblueʼ. The concentrations of macronutrients in leaves showed interactions between cultivar and doses of ammoniacal N, which did not allow obtaining a single dose of ammoniacal N that generate nutritional concentration values in leaves associated with greater fruit production in the four blueberry cultivars.

ABSTRACT Increasing paddy consumption can be done through efforts to increase yields by improving production technology, one of which is using organic nano silica fertilizer. Food biofortification efforts in paddy are also considered a solution for improving nutrition to help improve community nutrition. This research aims to determine the colour cultivar and dosage of nano silica organic fertilizer and the interaction between the two, which provide high growth and production and determine the nutritional quality of functional paddy. Functional paddy planting occurred in Manakku Village, Labakkang District, Pangkep Regency, South Sulawesi, from May to August 2023. The research was arranged in a separate plot design with the main plot varying doses (kg ha-1) of nano silica organic fertilizer consisting of control (d0), 500 (d1), 1000 (d2), and 1500 (d3), as well as subplots of four cultivars of red rice (Oryza sativa L.), namely Inpari 24 (v1), Pamelen (v2), Pamera (v3) and Inpago 7 (v4) as well as one cultivar of black rice Jeliteng (v5). The results were that the interaction of 1000 kg ha-1 organic nano silica fertilizer and red rice ‘Inpago 7’ (d2v4) provides the best yield of 5.62 t ha-1. Characters that have a significant positive correlation with yield are plant height (0.64**), number of productive tiller (0.74**), grain total (0.54*), and weight of 1000 grains (0.88**). The quality of functional rice based on glycaemic index (GI) analysis showed that the black rice ‘Jeliteng’ with a dose of organic nano silica fertilizer of 1000 kg ha-1 (58.9%) had the lowest GI value.

ABSTRACT The hidden hunger for Se in the world population is well known. As a strategy to address this issue, this study aimed to biofortify onion (Allium cepa L.), since it is a condiment vegetable consumed by different economic classes and is widely used in the food industry. To this end, Se doses (0, 10, 25, 50, 100 and 200 g ha-1) and application forms (soil and foliar) were evaluated on the biofortification of the bulb and crop yield. The Se source was sodium selenate. Via soil, Se was applied together with NPK fertilizer in the pre-transplantation of the seedlings. Via foliar application, Se was sprayed 77 d after seedlings were transplanted. The Se increased yield up to 99 g ha-1, which was 14.7% higher than the yield obtained in the crop not fertilized with Se. Foliar application of Se was more efficient than soil application in the biofortification of onion, although both were effective. With the dose that promoted the highest yield, the Se concentrations reached 0.487 and 0.317 mg Se kg-1 in onion dry mass, when the supply was made via foliar and soil applications, respectively. The increase in Se supply did not influence bulb quality, as demonstrated by the macro- and micronutrients content and pungency.
