RESUMO O pimentão, cultura de importância nutricional, destaca-se por seu valor de vitamina C. Diante da necessidade de práticas agrícolas sustentáveis, o estudo explorou o uso de biocarvões derivados de resíduos regionais como alternativa na cultura de pimentão. Nesse contexto, objetivou-se avaliar o efeito de biocarvões provenientes de cama de frango, fibra de coco e palha de arroz, nas características biométricas e físico-químicas de frutos de pimentão verde, na produção de frutos por planta e na produtividade. A pesquisa foi conduzida em campo no delineamento em blocos casualizados, em esquema fatorial 5 × 3 + 1, referentes a cinco doses de biocarvão (0, 3, 6, 9 e 12 t ha-1) e três tipos de biocarvão (fibra de coco, cama de aviário e palha de arroz) com quatro repetições, mais um tratamento adicional (adubação mineral). Foram avaliadas variáveis biométricas (comprimento e diâmetro dos frutos, espessura da casca, número de frutos, massa do fruto) e físico-químicas dos frutos (sólidos solúveis, acidez titulável, pH, vitamina C e teor de cinzas), produção e produtividade dos frutos. A produção de frutos de pimentão verde não foi influenciada pelos biocarvões, porém as doses de biocarvões influenciaram todas as variáveis analisadas com exceção da espessura da casca. Os teores de vitamina C e de sólidos solúveis foram maiores nos tratamentos com biocarvões e menores com adubação mineral.

ABSTRACT Bell pepper, a crop of nutritional importance, stands out for its vitamin C content. Given the need for sustainable agricultural practices, the present study explored the use of biochars derived from regional waste as an alternative in bell pepper cultivation. In this context, the present study aimed to evaluate the effect of biochars from poultry litter, coconut fiber, and rice straw on the biometric and physicochemical characteristics of bell pepper fruits, on fruit production per plant and on fruit yield. The experiment was performed in the field in a randomized block design, in a 5 × 3 + 1 factorial scheme, referring to five doses of biochar (0, 3, 6, 9, and 12 t ha-1) and three types of biochar (coconut fiber, poultry litter, and rice straw) with four repetitions, plus an additional treatment (mineral fertilization). Biometric variables (fruit length and diameter, skin thickness, number of fruits, fruit mass) and physicochemical variables of the fruits (soluble solids, titratable acidity, pH, vitamin C, and ash content), production and yield of the fruits were evaluated. The production of bell pepper fruits was not influenced by biochars, but the doses of biochars influenced all variables analyzed with the exception of skin thickness. Vitamin C and soluble solids contents were higher in treatments with biochar and lower with mineral fertilizer. Biochar produced from rice straw had the greatest influence on fruit acidification. importance content practices cultivation context litter fiber design scheme 0, 0 (0 6 9 ha1 ha ha-1 repetitions fertilization. fertilization . fertilization) diameter thickness mass acidity pH content, , content) evaluated fertilizer acidification ( ha-

RESUMO: O tomate (Solanum lycopersicum L.) é uma fruta rica em nutrientes e com alto teor de ácido glutâmico, tornando-o uma fonte adequada para a produção de ácido γ-aminobutírico (GABA) através da ação de bactérias ácido lácticas (BAL). As BAL desempenham um papel fundamental na fermentação láctica, melhorando o sabor e o valor nutricional dos produtos alimentares, contribuindo frequentemente para os seus benefícios para a saúde. Este estudo teve como objetivo isolar BAL produtoras de GABA de tomates e avaliar seu potencial para a produção de suco de tomate fermentado enriquecido com GABA. Os resultados indicam o isolamento de 15 cepas de BAL a partir de amostras de cinco tomates diferentes. Todas essas cepas demonstraram capacidade de produzir GABA, com níveis variando de 1,732 a 3,113 mg/mL, conforme determinado por cromatografia em camada delgada (CCD). Através de sequenciamento, a cepa promissora TO42, identificada como Weissella cibaria, foi selecionada para fermentação de suco de tomate. Além disso, o suco de tomate enriquecido com GABA foi fermentado com sucesso a 15 °Brix por 72 h, resultando no maior teor registrado de GABA e ácido láctico de 9.185 ± 0.398 mg/mL e 13.05 ± 1.56 g/L, respectivamente.

ABSTRACT: Tomatoes (Solanum lycopersicum L.) are nutrient-rich fruits with a high glutamic acid content, making them a suitable source for producing γ-aminobutyric acid (GABA) through the action of lactic acid bacteria (LAB). LAB plays a pivotal role in lactic fermentation, enhancing the taste and nutritional value of food products, often contributing to their health benefits. This study isolated GABA-producing LAB from tomatoes and assessed their potential for producing GABA-enriched fermented tomato juice. The results indicated the isolation of 15 LAB strains from the samples of five different tomatoes. All of these strains demonstrated the capability to produce GABA, with levels ranging from 1.732 to 3.113 mg/mL, as determined using thin-layer chromatography (TLC). Through sequencing, the promising strain TO42, identified as Weissella cibaria, was selected for tomato juice fermentation. Furthermore, GABA-enriched tomato juice was successfully fermented at 15 °Brix for 72 h, resulting in the highest recorded GABA and lactic acid content of 9.185 ± 0.398 mg/mL and 13.05 ± 1.56 g/L, respectively.

ABSTRACT: Sweet potato is an important food security crop, and the world market for this root is on the rise. Based on the physiological changes in plants in response to climatic conditions and fertilization, this study evaluated the effects of the growing season (rainy and dry season) and P2O5 doses (0, 50, 100, 200 and 400 kg ha-1) on total yield, marketable classes yields, as well as chemical composition of storage roots of two sweet potato cultivars. The storage roots yield was greater in the rainy season. The optimum agronomic and economic doses were 128 and 95 kg ha-1 P2O5 for the cultivar Canadense. Cultivar Uruguaiana did not respond to phosphate fertilization, but its storage roots had higher contents of dry matter, lipids, fibers, total and reducing sugars, and starch. Sweet potato cultivation in the rainy season with doses up to 100 kg ha-1 P2O5 increase root yield in marketable size classes in higher economic value and with higher carbohydrate contents. The results can help producers schedule the planting and harvesting of sweet potatoes throughout the year and contribute to the seasonal management of phosphate fertilizer application.

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.

RESUMO: A fisiologia das plantas muda ao longo do dia porque os fotoassimilados podem aumentar a concentração de carboidratos solúveis em água à tarde em comparação com a manhã. Este estudo teve como objetivo avaliar o efeito do horário de colheita na composição morfológica da silagem de milho de planta inteira, tamanho de partícula, perfil de fermentação, composição química, degradação in vitro e estimativa da produção de leite. Um ensaio agronômico de dois anos foi realizado em delineamento inteiramente casualizado, e um silo experimental foi produzido por cada parcela (n = 16). A colheita da tarde aumentou (P < 0,01) o teor de matéria seca em relação à colheita da manhã. A época de colheita não afetou (P ≥ 0,32) a proporção de grãos, colmos e folhas do milho e o tamanho das partículas da silagem. Entretanto, a colheita da manhã aumentou (P = 0,01) a recuperação de matéria seca e não teve efeito (P ≥ 0,10) no pH da silagem e nas concentrações de ácido láctico e acético em comparação à colheita da tarde. Além disso, a colheita da tarde, em vez da colheita da manhã, aumentou (P ≤ 0,05) o amido da silagem, os carboidratos solúveis em água, a lignina detergente ácida e o teor de extrato etéreo e a degradação in vitro da matéria seca. Controversamente, os tratamentos não mostraram efeito (P ≥ 0,14) na concentração de energia da silagem, no conteúdo energético estimado e na produção de leite. Assim, a colheita da manhã produz mais matéria seca da silagem, mas a colheita da tarde melhora o valor nutricional da silagem de milho sem impacto na produção estimada de leite.

ABSTRACT: Plants’ physiology changes through the day because photoassimilates can increase water-soluble carbohydrate concentration in the afternoon compared to the morning. This study evaluated the harvest time effect on whole-plant corn silage morphological composition, particle size, fermentation profile, chemical composition, in vitro degradation, and estimated milk yield. A two-year agronomic assay was performed in a completely random design, and one experimental silo was produced by each parcel (n = 16). The afternoon harvest increased (P < 0.01) dry matter content compared to the morning harvest. Harvest time did not affect (P ≥ 0.32) corn grain, stalk, leaf proportion, and silage particle size. However, the morning harvest increased dry matter recovery (P = 0.01) and had no effect (P ≥ 0.10) on silage pH and concentrations of lactic and acetic acid compared to the afternoon harvest. In addition, afternoon harvest instead of morning harvest increased (P ≤ 0.05) silage starch, water-soluble carbohydrates, acid detergent lignin, and ether extract content and dry matter in vitro degradation. Controversially, treatments showed no effect (P ≥ 0.14) on silage energy concentration, estimated energy content, and milk yield. Thus, the morning harvest produces more silage dry matter, but the afternoon harvest improves corn silage’s nutritional value with no impact on estimated milk yield.

Summary: Avocado is a fruit (Persea americana), that has increased its consumption worldwide. Mexico is the main producer and exporter of avocado in the world, representing more than 30% of the world harvest, of which 73.2% of the total avocado production in Mexico was concentrated in the state of Michoacán. In the state of Michoacán, there is a constant production of avocado fruit throughout the year, but this production is affected by the variation in climate, water management and flowering type, putting agricultural production and sustainable development at risk. The objective of this study was to evaluate the climatic effect, water management, and flowering type on fruit nutrient content in six orchards in the state of Michoacan. Six orchards were evaluated in the towns of Basilia, Cheranguerán, Tecario, Araparicuaro, Peribán and Patamburu in the state of Michoacan, which represent 90% of the climate types (TC), predominant in the state (ACW1, ACW2 and CW1)., with 100% of the water regime (irrigated and seasonal, RH) and 97% of the type of fruit produced (loca and normal, FF). The dry matter contents and total mineral content of the fruit were evaluated. The arrangement of treatments was a factorial [A= water regime (RH); B= type of climate (TC); C= floral flow (FF)], distributed completely randomly with 20 repetitions taking each tree as a repetition. The results indicated that the dry matter content is affected by TC, but not by RH and FF, FF affects the nutritional content more than TC and RH. The type of climate is the factor with the least impact on the mineral content of the fruit. In floral flow, the total nutritional content was significant in four elements with higher values for N, Cl, and Zn in crazy fruit and Na in normal fruit.

ABSTRACT Quinoa is an Andean grain recognized for its high nutritional value and its ability to tolerate extreme environmental conditions. Most publications on this species have focused on agronomic or agroindustrial aspects, leaving uncertainties about the relationship between biological yield and compositional characteristics of the grain. Therefore, the objective of this study was to analyze the biological performance and agroindustrial properties of the seeds of three quinoa cultivars widely used in Colombia. A completely randomized design was used with the Pasankalla, Soraca and Titicaca cultivars. In the first phase, the physiological behavior of the plants under controlled conditions was evaluated. In the second phase, seed production and some compositional characteristics were determined in the laboratory. In general, the three cultivars showed significant diversity and differences in morphological, physiological and biochemical traits. The Titicaca cultivar presented the earliest maturity, taking 115.6 days to reach harvest, while Soraca was the cultivar with the highest production, achieving 321 g of seeds per plant. Regarding the characteristics of the grain, the Soraca and Pasankalla cultivars had the highest protein content, with values of 14.33 and 13.76%, respectively.

Por lo tanto, el objetivo de este estudio fue analizar el desempeño biológico y las propiedades agroindustriales de las semillas de tres cultivares de quinua ampliamente utilizados en Colombia. Se utilizó un diseño completamente al azar con los cultivares Pasankalla, Soracá y Titicaca. En la primera fase se evaluó el comportamiento fisiológico de las plantas en condiciones controladas. En la segunda fase se determinó en laboratorio la producción de semillas y algunas características composicionales. En general, los tres cultivares mostraron diversidad y diferencias significativas en rasgos morfológicos, fisiológicos y bioquímicos. El cultivar Titicaca presentó la madurez más temprana, tardando 115,6 días en alcanzar a cosecha, mientras que Soracá fue el cultivar con mayor producción, logrando 321 g de semillas por planta. En cuanto a las características del grano, los cultivares Soracá y Pasankalla presentaron el mayor contenido de proteína, con valores de 14,33 y 13,76%, respectivamente.

ABSTRACT The cowpea is a legume with a high nutritional value and represents one of the most important self-consumption items in the country. However, under storage conditions its main problem are bruchids, which decrease the nutritional value and fertility of the seeds. Bruchids spread more frequently unintentionally throughout the world, this is due their adaptability. In the first months of 2023, damage was observed to stored cowpea grains of the species Vigna unguiculata, presenting round holes, decreasing the nutritional value and fertility of the seeds. The inspection of grains recorded the presence of a beetle, which was identified as Decellebruchus atrolineatus, Family Chrysomelidae, Subfamily Bruchinae.

RESUMEN El poroto es una leguminosa comestible con un alto valor nutritivo y representa uno de los rubros de autoconsumo más importantes en el país. Sin embargo, en condiciones de almacenamiento su principal problema son los brúquinos, quienes disminuyen el valor nutricional y la fertilidad de las semillas. Por la adaptación que poseen, los brúquinos, se diseminan con mayor frecuencia de manera involuntaria. En los primeros meses del año 2023, fueron observados daños en granos almacenados de poroto de la especie Vigna unguiculata, presentando orificios redondeados. La inspección de dichos granos registró la presencia de un coleóptero, que fue identificado como Decellebruchus atrolineatus, Familia Chrysomelidae, Subfamilia Bruchinae.

Este trabajo aborda el uso tanto de la metodología del Design Thinking y de la teoría de la pirámide de la sostenibilidad para mejorar el valor nutritivo y saludable de un alimento popular, buscando al mismo tiempo conservar e incrementar el valor de ese alimento y beneficiar al consumidor. El análisis de la pirámide de sostenibilidad en el diseño de un alimento funcional utilizando la metodología Design Thinking enfatiza el valor nutricional para promover la participación en el diseño de alimentos nutritivos y saludables para la población. Al aplicar este método para el diseño y mejora de alimentos se cubren las expectativas básicas del usuario final de forma empática, permitiendo obtener una mayor certidumbre respecto al emprendimiento en nuevos productos alimentarios con un enfoque sustentable.

Abstract Popular food available to people has social and nutritional relevance and impacts health in an important way. This work addresses the use of both the Design Thinking methodology and the sustainability pyramid theory to improve the nutritional and healthy value of a popular food, seeking at the same time to preserve and increase the value of that food and benefit the consumer. The analysis of the sustainability pyramid in the design of a functional food using the Design Thinking methodology emphasizes nutritional value to promote participation in the design of nutritious and healthy foods for the population. By applying this method to the design and improvement of food, the basic expectations of the end user are met in an empathetic way, allowing greater certainty to be obtained regarding entrepreneurship in new food products with a sustainable approach.

Abstract Introduction : Meningeal cryptococcosis (MC) is a frequent cause of meningoencephalitis in people living with HIV (PLHIV), leading to substantial morbidity (20- 55%). Clinical characteristics, lethality and adverse prog nostic factors in PLHIV with MC admitted to intensive care units (ICUs) are described. Methods : A retrospective observational study. Period from 11/21/2006 to 05/24/2023. It involved 154 adult PLHIV diagnosed with MC and admitted to ICUs. Percen tages and absolute values were compared by Chi-Square or Fisher’s test and medians by Mann-Whitney test. The association with mortality was assessed by logistic re gression. SPSS 23.0 software was used. A p-value <0.05 was considered significant. Results : Patients who died and those who survived were comparable in age and sex (p>0.05). Univariate analysis showed that impaired functional and nutritio nal status, lack of previous highly active antiretroviral therapy, CD4 <100 cells, APACHE II ≥13 and a PLHIV prognostic score ≥8 points, requiring mechanical venti lation (MV), respiratory failure, renal failure, neurological dysfunction or sepsis could be associated (p<0.05) with mortality. Logistic regression established that impaired functional and nutritional status, a PLHIV prognostic score ≥8, need for MV and presence of sepsis would be independent variables associated with mortality. Conclusion : The results indicate that altered functio nal and nutritional status, a PLHIV prognostic score ≥ 8 points, requiring MV and suffering sepsis on admission to the ICU are more frequent in deceased patients, and they could therefore serve as independent variables to predict a higher risk of mortality.

Resumen Introducción : La criptococosis meníngea (CM) es una causa frecuente de meningoencefalitis en personas que viven con HIV (PVHIV) y produce una importante morbi-mortalidad (20-55%). Se describen las características clínicas, la letalidad y las variables de mal pronóstico en PVHIV con CM, en unidades de cuidados intensivos (UCI). Métodos : Estudio observacional y retrospectivo. Pe ríodo 21/11/2006 a 24/05/2023. Población evaluada: 154 PVHIV adultos, admitidos en UCI con diagnóstico de CM. Los porcentajes y valores absolutos, fueron comparados mediante Chi-Cuadrado o test de Fisher y las medianas mediante test de Mann-Whitney. La asociación con mortalidad se evaluó por regresión logística. Se utilizó el programa SPSS 23.0. Un valor p<0.05 fue considerado significativo. Resultados : Los pacientes que fallecieron y los que so brevivieron fueron comparables en edad y sexo (p>0.05). El análisis univariado, observó que un estado funcional y nutricional alterado, falta de tratamiento antirretroviral previo (TARV), CD4 <100 células/μl, APACHE II ≥13 y un score pronóstico de PVHIV ≥8 puntos, requerir ventilación mecánica (VM), sufrir insuficiencia respiratoria, renal, disfunción neurológica o sepsis, podrían estar asociados (p<0.05) con mortalidad. La regresión logística estableció que un estado funcional y nutricional alterado, un score pronóstico PVHIV ≥8, necesitar VM y sufrir sepsis serían variables independientes asociadas a mortalidad. Conclusión : Los resultados indican que el estado funcional y nutricional alterado, un score pronóstico PVHIV ≥8 puntos, requerir VM y sufrir sepsis al ingreso a UCI podrían servir como variables independientes para predecir un mayor riesgo de mortalidad.

Resumen El objetivo fue evaluar el contenido nutricional e índice de clorofila (ICC) de seis forrajes arbóreos, para ello se analizó el ICC, proteína, fósforo, potasio, calcio, magnesio y azufre a 30, 45 y 65 días. Se utilizó un diseño de bloques completamente al azar en parcelas divididas con seis repeticiones. Los resultados se compararon con un test de Tukey al 5 %, se realizaron correlaciones (Pearson) y regresiones lineales para determinar el efecto del ICC con los nutrientes. Los contenidos de ICC, proteína, fósforo, potasio, calcio, magnesio y azufre presentaron diferencias estadísticas (p < 0,05) para los factores arbustos forrajeros e intervalos de corte, y su interacción. Leucaena presentó mayores contenidos de ICC en todos los intervalos. Los resultados de proteína fueron mayores en Gliricidia (30 días), Leucaena (45 días) y Moringa (60 días). Para fósforo los mejores valores se obtuvieron en Morus (30 días) y Moringa (30, 45 y 60 días). Tithonia alcanzó mayor concentración de potasio y calcio en los tres intervalos de corte, así como para magnesio (30 días). El ICC determinado con medidores de lectura directa permitió correlacionarse con el contenido de proteína y los nutrientes del tejido foliar P, K, Ca, Mg, S.

Abstract The objective was to evaluate the nutritional content and chlorophyll index (CCI) of six tree forages, for which CCI, protein, phosphorus, potassium, calcium, magnesium, and sulfur were analyzed at 30, 45, and 65 days. A completely randomized block design in divided plots with six replications was used. Results were compared with a 5% Tukey test, correlations (Pearson) and linear regressions were performed to determine the effect of ICC on nutrients. The contents of ICC, protein, phosphorus, potassium, calcium, magnesium, and sulfur showed statistical differences (p < 0.05) for the factors forage shrubs, cutting intervals, and intercropping. Leucaena presented higher contents of ICC in all intervals. Protein results were higher in Gliricidia (30 days), Leucaena (45 days), and Moringa (60 days). For phosphorus, the best values were obtained in Morus (30 days) and Moringa (30, 45, and 60 days). Tithonia reached higher potassium and calcium concentrations in the three cutting intervals, as well as for magnesium (30 days). The ICC determined with direct reading meters allowed correlation with protein content and leaf tissue nutrients P, K, Ca, Mg, S.

Abstract The Cerrado and Pantanal are present in the Midwest region, regions with a diversity of fauna and flora and high potential for exploration. The native fruits have characteristic flavors, significant nutritional value and compounds of great biotechnological relevance. Some native fruits and manufactured products are sold at open markets, along highways, at supply centers and at supermarket chains. Thus, this study aimed to verify the knowledge and consumption profile of native fruits from the Cerrado and Pantanal of Mato Grosso do Sul (MS) by the population. This study was exploratory, with a non-probabilistic sampling design and convenience sampling. An online questionnaire was used containing questions to characterize the sample and refering to knowing, tasting, form of consumption and place of obtaining 12 native fruits of the Cerrado and Pantanal, namely: pequi, bocaiuva, mangaba, cagaita, baru, murici, mama-cadela, buriti, araticum and guabiroba. Among the 616 valid answers, the sample was mostly composed of adults (92.29%), female (79.06%), monthly income of up to 5 minimal wages (74.72%), with complete higher education (45.94%), born (42.53%) and residents (53.90%) of MS. The best known and most tried fruit was the pequi, while the mama-chada was the least known and tried. The main form of consumption mentioned was “in natura” and the main form of obtaining was “From the Cerrado/Pantanal itself”. Participants presented moderate knowledge and a low consumption of native fruits from the Cerrado and Pantanal of MS. Thus, the importance of valuing regional food practices is highlighted as a way to increase local culture and encourage the consumption of native fruits, expanding their dissemination to the population. region exploration flavors relevance markets highways chains Thus MS (MS population exploratory nonprobabilistic non probabilistic knowing tasting 1 namely pequi bocaiuva mangaba cagaita baru murici mamacadela, mamacadela mama cadela, cadela mama-cadela buriti guabiroba 61 answers 92.29%, 9229 92.29% , 92 29 (92.29%) 79.06%, 7906 79.06% 79 06 (79.06%) 74.72%, 7472 74.72% 74 72 (74.72%) 45.94%, 4594 45.94% 45 94 (45.94%) 42.53% 4253 42 53 (42.53% 53.90% 5390 90 (53.90% mamachada chada natura From CerradoPantanal itself. itself . itself” 6 922 92.29 9 2 (92.29% 790 79.06 7 0 (79.06% 747 74.72 (74.72% 459 45.94 4 (45.94% 42.53 425 (42.53 53.90 539 (53.90 92.2 (92.29 79.0 (79.06 74.7 (74.72 45.9 (45.94 42.5 (42.5 53.9 (53.9 92.
