RESUMO: A batata-doce é uma cultura importante para a segurança alimentar com mercado mundial em ascensão. Com base nas alterações fisiológicas das plantas em resposta às condições climáticas e à fertilização, este estudo avaliou os efeitos da época de cultivo (período chuvoso e seco) e de doses de P2O5 (0, 50, 100, 200 e 400 kg ha-1) na produtividade total e por classes comerciais, bem como, a composição química das raízes de armazenamento de duas cultivares de batata-doce. A produtividade de raízes tuberosas foi maior na estação chuvosa. As doses ótimas agronômica e econômica foram de 128 e 95 kg ha-1 de P2O5 para a cultivar Canadense. A cultivar Uruguaiana não respondeu a adubação fosfatada, mas suas raízes tiveram maiores teores de matéria seca, lipídios, fibras, açúcares totais e redutores e amido. O cultivo de batata-doce no período chuvoso com doses de até 100 kg ha-1 de P2O5 aumenta a produtividade de raízes em classes de maior valor econômico e com maiores teores de carboidratos. Estes resultados ajudam os produtores a planejarem o plantio e a colheita da batata-doce ao longo do ano e contribui para a gestão da aplicação de fertilizantes fosfatados.

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.

ABSTRACT. The objective of this work was to study the biomass production and chemical composition of the different parts of the cassava plant during the first and second vegetative cycles, with the aim of providing data that can contribute to the understanding of the response of cassava cultivars to different harvest ages. The experimental design consisted of randomized blocks in split plot scheme. Plots were represented by cultivars IAC 90 and IAC 118-95 and subplots by crop age (2, 4, 6, 8, 10, 12, 14, 16, and 18 months after planting). Our results showed that the ‘IAC 90’ allocated a higher proportion of assimilates to the leaves, stem and planted cutting than the ‘IAC 118-95’, which was more efficient in allocating dry matter to the storage roots. Storage roots showed an increase of more than 50% in starch content 14 months after planting. The cultivar IAC 118-95 is distinguished by the higher harvest index, allowing earlier harvesting, with possible valorisation of the leaves as industrial raw material. Variables showed different degrees of inter-relationships amongst themselves. Total plant fresh matter and dry matter yields were positively correlated with growth parameters and root starch for both cultivars. Harvest time and cultivar are key factors that should be considered to increase profits in the cassava agro-industrial chain.

ABSTRACT Diversifying cultivars and intercropping with lemongrass can innovative strategies for banana growers to enhance the variety, profitability and sustainability of their orchards and to adapt to climate change. This study took place in the state of São Paulo, a subtropical region of southeastern Brazil and assessed the duration of the cropping cycles, growth and yield performance, and leaf nutritional content of banana cultivars BRS FHIA Maravilha, SCS 451 Prata Catarina, BRS Pacoua and Prata Anã when intercropped with lemongrass. The field experiment spanned two consecutive growing seasons. The growth, yield and nutrient content in the leaves of banana cultivars exhibited similar performance in both monoculture and intercropping with lemongrass. A shorter cycle was observed only in the first harvest with the lemongrass intercrop. The Prata Anã cultivar stood out for its earlier cycle, lower plant height and higher average yield per year. These findings are valuable for planning cultivar diversification in new orchards, exploring the potential for intercropping with lemongrass, and identifying the genotypes and cropping systems that are better suited to adverse climatic conditions. variety change Paulo cycles Maravilha 45 Catarina seasons intercrop year conditions 4

Abstract Global mango production generates significant agricultural and industrial waste, including non-standard fruits and peels. Herein, flours obtained from the immature fruits of four mango cultivars (Haden, Keitt, Parwin, and Tommy Atkins) were characterized for their physicochemical properties with the goal of valorization as an ingredient in functional food products. Regardless of cultivar, the peel flours represented excellent sources of fiber, with notable calcium, magnesium, manganese, carotenoids, and antioxidant contents as well as high percentage of large particles and good water retention capacity. Pulp flours exhibit high starch content, light color, and fine granulometry. The mango cultivars strongly interfered with the differentiation of the mango peel and pulp flours. The results presented herein show that understanding the characteristics of flours obtained by processing different parts of the fruits of various cultivars can produce composite mango flours with different nutritional and technological properties, expanding their possible uses in food products and driving sustainable agricultural production in terms of efficient crop waste management. nonstandard non standard peels Herein Haden, Haden (Haden Keitt Parwin Atkins cultivar fiber calcium magnesium manganese carotenoids capacity content color granulometry management

Abstract Brazil is a major producer of bananas, being the world's fourth-largest producer. The fruit is a source of minerals and vitamins and, when green, has a high content of resistant starch. Among the possibilities of processing, green banana flour has gained prominence due to its physical, nutritional, and functional characteristics, which can be used for the making of different food products. However, the raw material and the processing steps can influence these characteristics. Thus, this study aimed to provide information ranging from the choice of raw material to the sensory acceptance of consumers. The present work discussed the influence of ripening on fruit characteristics, processing stages and flour characteristics as a result of the different used fruits part or cultivar/variety of banana, and the possibilities of products with good technological quality and sensory acceptance of products made with green bananas flours by Brazilian consumers. One of the main differences provided by the cultivar is the flour yield, which is higher in banana cultivars with lower moisture content and selected for frying. There is little information regarding the whole green banana flour, which could reduce waste and contribute nutritionally to preparations. New products having green banana flours as an ingredient show wide possibilities for a partial or total replacement to other flours, as well as good sensory acceptance, which has led to a growing interest in banana processing and its growing market. worlds world s fourthlargest fourth largest starch physical nutritional However Thus consumers cultivarvariety variety yield frying preparations market

Abstract The constant need for innovation in the food industries to meet the demands of consumers and the growing market for gluten-free and high-protein products have driven studies of mixed flour. In this study, 'BRS Platina' banana fruits were processed to obtain Whole Green Banana Flour (WGBF) and Green Banana Pulp Flour (GBPF) as well as leaves of Ora-pro-nóbis Flour (OPNF). Mixed flours were prepared by blending banana flours (WGBF or GBPF) with increasing levels of OPNF (from 5 to 25%). Flours were analyzed for physicochemical characteristics, mineral contents, Water Absorption Index (WAI), Water Solubility Index (WSI), and color. The main component of banana flours was starch, in which GBPF has the highest content. The WGBF had a higher mineral content, and in both flours, the potassium was at a greater level. OPNF showed the highest protein and mineral contents. Independent of the type of banana flour, mixed flours were darker, and had higher WAI and considerable increases in Mg, Fe, and Zn than no mixed ones. The blend of banana flours and Ora-pro-nóbis leaf flour can be a viable combination for preparing a variety of food products, due to its nutritional and technological properties. glutenfree gluten free highprotein high study BRS Platina (GBPF Orapronóbis Ora pro nóbis OPNF. .

Resumo O objetivo deste trabalho foi avaliar cultivares de bananeira quanto aos seus rendimentos agronômicos e características de amido. O experimento foi realizado em blocos ao acaso, com arranjo fatorial de duas cultivares ('BRS Conquista' e 'BRS Platina') e dois ciclos da cultura, com três plantas por tratamento e cinco repetições. Avaliaram-se a produção e a qualidade do amido dos frutos. 'BRS Conquista' apresentou frutos menores; no entanto, mostrou maior massa comercial e produtividade do cacho do que 'BRS Platina'. Os amidos diferiram quanto às principais características físico-químicas, exceto quanto ao padrão de difração de raios X (tipo B) e teor de fósforo (0,0058–0,0060%). 'BRS Platina' destacou-se por seu maior teor de amido resistente (74,55%) que diferiu do amido isolado de 'BRS Conquista'. No entanto, o amido de 'BRS Conquista' apresentou as seguintes características: grânulos maiores (34,74 µm), com maior cristalinidade (33,64%); menor poder de inchamento e solubilidade (26,77 g g-1 e 19,21%, respectivamente); e maiores quebra de viscosidade, tendência à retrogradação e viscosidade final (67,06, 182,42 e 341,39 RVU, respectivamente). 'BRS Conquista' mostra características de produção favoráveis ao processamento para extração de amido. O maior teor de amido resistente de 'BRS Platina' pode justificar comercialmente sua menor produção agronômica. Os amidos das duas cultivares apresentam características desejáveis para aplicações industriais diversas.

Abstract The objective of this work was to evaluate the banana cultivars for their agronomic yield and starch characteristics. The experiment was carried out in a randomized complete block design, with a factorial arrangement of two cultivars ('BRS Conquista' and 'BRS Platina') and two crop cycles, with three plants per treatment, and five replicates. Fruit yield and starch quality were evaluated. 'BRS Conquista' showed smaller fruit; however, it had a greater marketable bunch weight and yield than 'BRS Platina'. Starches differed for the main physicochemical characteristics, except for X-ray diffraction pattern (B type) and phosphorus content (0.0058–0.0060%). 'BRS Platina' stood out for its higher content of resistant starch (74.55%) that differed from the starch isolated from 'BRS Conquista'. However, the starch of 'BRS Conquista' showed the following characteristics: larger granules (34.74 µm), with greater crystallinity (33.64%); less swelling power and solubility (26.77 g g-1 and 19.21%, respectively); and greater breakdown, setback and final viscosity (67.06, 182.42, and 341.39 RVU, respectively). 'BRS Conquista' shows favorable production characteristics for processing to obtain starch. The higher resistant starch content of 'BRS Platina' may commercially justify its lower agronomic yield. Starches of the two cultivars show desirable characteristics for different industrial applications.

HIGHLIGHTS Chips from orange-fleshed sweet potato have a good acceptability. Drying process showed retention of carotenoids total content. Chips from drying or frying process showed high resistant starch content.

ABSTRACT. Calcium chloride application on fruits maintains the firmness of fruits, decreases storage breakdown and rot, extends shelf-life, and increases vitamin C and calcium content. Blackberries have low post-harvest durability due to the intrinsic characteristics of their fruits, mainly the high respiratory rate and low firmness, which causes problems in the production chain of fresh fruits. The current study aimed to evaluate the effects of pre-harvest application of calcium chloride on the fruits of ‘Tupy’ blackberry (Rubus spp.). A randomized block design for a factorial scheme was used, i.e. calcium chloride concentrations (0, 1.5, 3, and 4.5%) and number of applications (1, 2, and 3). Multiple applications occurred between 5-day intervals. The results showed that the calcium content in the fruits increased with a single application of 2.2%, but a decrease in mass loss was observed with a 4.5% application. The results also indicated great firmness and ascorbic acid content of fruits of ‘Tupy’ blackberry, in addition to the significant increase in fruit size and mass. However, in general, the content of soluble solids, sugars, antioxidant activity and total polyphenols decreased.

Abstract Native cassava starch was gelatinized under different pretreatment conditions (preheating temperature, starch concentration and heating time) and spray-dried. A rotational compound central design was used to test the three independent variables: the preheating temperature, starch concentration, and heating time, and the behavior of the system was assessed by response surface methodology. The results showed a significant effect of both the preheating temperature and heating time on the cold viscosity. The combination of the preheating temperature and starch concentration affected the crystallinity, enthalpy change, solubility, and final viscosity. Modification by spray-drying resulted in a decrease in the crystalline regions, and enthalpy change, as well as an increase in the cold viscosity. The optimal conditions for obtaining partially gelatinized cassava starch with high cold viscosity and lower breakdown, desirable characteristics for commercial pregelatinized starch, are as follows: starch concentration of 25%, preheating temperature of 52 °C, and processing heating time of 10 min.

ABSTRACT Nineteen genotypes of bananas and plantains were analysed in order to differentiate the subgroups and/or groups of consumption or industrial use. Genotypes of banana and plantain from different genomic groups and in three ripening stages (2, 5 and 7) were studied in relation to physical and physicochemical characteristics, including bioactive compounds. Furthermore, with the obtained data analysed by multivariate statistical analyses (Principal Component Analysis) it was possible to relate all analysed characteristic profile of samples with the different genotype. The three ripening stages were differentiate by total soluble solids, titratable acidity, chrome (C*) and the carotenoids contents. ‘Ney Poovan’ contain high total soluble solid content and pulp-to-peel ratio, an interesting result for the promotion of this genotype for in natura consumption. ‘Ney Poovan’, ‘Ouro da Mata’, ‘Pelipita’ and ‘Tiparot’ are sources of antioxidant compounds. The genotypes ‘Pelipita’ and ‘Samurá B’ are promising for the industrial use, mainly for the processing of banana chips, for both green and ripe fruit.

O figo possui problemas quanto à sua conservação no período pós-colheita, visto que é fruta climatérica e de alta perecibilidade. Diante disto, o trabalho teve como objetivo avaliar o uso de cloreto de cálcio em pós-colheita, em frutos do cultivar de figueira ‘Roxo de Valinhos’. Foram utilizados frutos colhidos em pomar experimental da Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP), localizada no município de Botucatu, estado de São Paulo, Brasil. Os frutos foram transportados para o departamento de Horticultura, onde receberam tratamento com 0, 1, 2 e 3% de CaCl2, pelo método de imersão. Posteriormente, foram armazenados em câmara fria (5± 1ºC e UR 80± 5%), embalados em bandejas de poliestireno expandido e envoltos por filme PVC. As variáveis avaliadas foram: firmeza, pH, sólidos solúveis, acidez titulável, índice de maturação e teor de açúcares totais, redutores e não redutores após 5, 10, 15 e 20 dias de armazenamento. Avaliou-se ainda a perda percentual de massa, em intervalos de 2 dias, até ao vigésimo dia de armazenamento. O uso de cloreto de cálcio em pós-colheita promoveu poucas alterações na qualidade dos frutos durante o armazenamento. Todas as características de qualidade dos frutos variaram em função do período de armazenamento, com exceção dos teores de açúcares totais e sólidos solúveis.

The fig fruits have problems with their post-harvest shelf-life, due to the fact that the fruit is climacteric and it has high perishability. Faced with this issue, this paper objective was to evaluate the use of calcium chloride in the post-harvest period of ‘Roxo de Valinhos’ fruits. The fruits were harvested from an experimental orchard and sent to the horticulture department, where they were treated with different concentrations of CaCl2 (0, 1, 2, and 3%), using the dipping method. The fruits were stored in cold chamber (5±1ºC and 80± 5% RH), packed with polystyrene trays and covered with PVC film. Evaluations were realized at 5, 10, 15 and 20 days after storage, when were observed the following characteristics: firmness, pH, total soluble solids, titratable acidity, maturation index and sugar content. The weight loss percentage was also evaluated every 2 days until the 20th day of storage. Calcium chloride applications on the post-harvest period of fig fruits promoted few changes in the fruit quality during the storage period. All the quality characteristics vary over the days of storage, except total sugar content and total soluble solids.

RESUMO: Este trabalho teve por objetivo avaliar os efeitos dos parâmetros de extrusão sobre as características físicas de misturas extrusadas de farinha de folhas de mandioca e amido. O delineamento central composto rotacional, com quatro variáveis independentes, e a metodologia de superfície de resposta foram utilizados para avaliar os resultados dos parâmetros de cor (L*, a*, b*), índice de absorção de água, índice de solubilidade em água e propriedades de pasta, de acordo com as variações da percentagem de farinha de folha (1,5 a 7,5%), da temperatura de extrusão (60 a 100ºC), da rotação da rosca (175-231rpm) e da umidade (20 a 30%). As condições do processo de extrusão afetaram a cor, os índices de absorção de água e solubilidade em água e as propriedades de pasta das misturas. As intermediárias testadas dos parâmetros variáveis levaram à obtenção de produtos extrusados com maior viscosidade fria e índice de absorção de água e de cor clara, qualidades desejáveis para produtos de preparação rápida.

ABSTRACT: The current research aimed to evaluate the effects of extrusion parameters on the physical characteristics of extruded blends of cassava leaf flour and starch. A factorial central composite design with four independent variables and the response surface methodology were used to evaluate the results of color parameters (L*, a*, b*), water absorption index, water solubility index and paste properties, according to the variations in the leaf flour percentage (1.5 to 7.5%), extrusion temperature (60 to 100ºC), screw speed (175 to 231rpm) and moisture (20 to 30%). Extrusion conditions affect color, water absorption and water solubility indexes and paste properties of blends. The intermediate tested conditions of variable parameters lead to obtain extruded products with higher cold viscosity and water absorption index and light color, desirable qualities for rapid preparation products.
