Post-harvest quality in the 'Tommy Atkins' mango for different harvest times Oswald Renaud Koblam Ahouangbonou, Leandro Timoni Buchdid Camargo Neves, Ozimar de Lima Coutinho Revista De Agricultura Neotropical, 2024 Determining the correct harvest time is essential for maintaining post-harvest fruit quality. The aim of the present study was to investigate the biochemical and physiological effect of three different harvest times on maintaining post-harvest quality in ‘Tommy Atkins’ mangoes from the state of Roraima, sold in markets in the city of Manaus. The treatments consisted of the different harvest times: control, harvested 90 days after anthesis; early harvest, harvested 70 days after anthesis; and late harvest, harvested 105 days after anthesis. At the end of the experimental period, mangoes harvested at 70 DAA were found to have a low carotenoid content, with the pulp unable to reach commercial maturity; the pulp had a high level of firmness, with the highest concentrations of vitamin C and phenolics, and the greatest antioxidant activity. When the mangoes were harvested at 105 DAA, the pulp had the least firmness and a sugar content very close to that of the early-harvested fruit, with lower concentrations of phenolics and vitamin C, and lower antioxidant activity. On the other hand, the fruit harvested at 90 DAA showed adequate physical resistance and acceptable results for sensory quality, functional compounds and antioxidant activity.
Aggregate stability of an Ultisol in regions of the brazilian Amazon Diego Lima de Souza Cruz, José Frutuoso do Vale Júnior, Leandro Timoni Buchdid Camargo Neves, Jessica Milanez Tosin Lima, Laís De Brito Carvalho, et al. Revista De Agricultura Neotropical, 2024 The aggregate stability is essential for water infiltration, soil aeration and root penetration resistance, impacting water infiltration, moisture retention, soil aeration and root penetration resistance. Inadequate agricultural practices can limit root growth, cause compaction, reduce water infiltration and increase water erosion. This study evaluated the stability of aggregates of an Ultisol in the Amazon, including different ecosystems: natural forest, natural savannah, forest converted to pasture and savannah converted to pasture. Three soil depths were analyzed at 0.00 to 0.10 m, 0.10 to 0.20 m and 0.20 to 0.40 m. The properties evaluated included aggregate classes, geometric mean diameter, weighted mean diameter, dispersed clay, degree of clay flocculation, sensitivity index and organic matter. The results showed that the conversion of natural environments to pasture did not significantly affect aggregate stability indices, suggesting that proper pasture management can maintain the structural quality of the soil.
Determining the harvest point of ‘Murupi’ peppers packed in plastic bags under cold storage Leandro TBC Neves, Daniel M de Oliveira, Paulo Roberto R Rocha Horticultura Brasileira, 2022 Peppers of the genus Capsicum are rich in antioxidants and considered to be an excellent source of compounds, which can bring benefits for human health, such as vitamin C and phenolic compounds. These compounds are influenced by the ripening stage of the fruits. Thus, the aim of this study was to determine the ideal harvest point for ‘Murupi’ pepper fruits, targeting the consumer market, based on physical, chemical, and functional attributes. These attributes were evaluated during postharvest, being the fruits packed in low density polyethylene plastic film (LDPE) and submitted to cold storage (25±1°C and 95±3% U.R.) for 20 days. The treatments consisted of three different fruit maturation stages at harvest time (fruit peel color: green, partially red and totally red). The authors analyzed the vitamin C, total and soluble fibers, ORAC (Oxygen Radical Absorbance Capacity), DPPH (2.2-diphenyl-1-picrylhydrazyl), total and reducing sugars, total phenolics, carotenoids, capsaicin and anthocyanins. The fruits harvested in immature stage (green) showed the highest values of vitamin C, total phenolics and, capsaicin contents, and also the highest averages of fruit antioxidant activity. The use of 0.10 mm-thick LDPE packages showed to be effective in delaying the maturation of pepper fruits in relation to sensory attributes, especially in terms of total fiber contents, being also observed, in this case, better maintenance of vitamin C and capsaicin contents, phenolic compounds and the highest antioxidant activity.
Postharvest quality of two sweet potato cultivars submitted to different harvest ages Thayane de A Silva, Leandro TBC Neves, Daniela C dos S Campos, Laís de B Carvalho, Lailson O de Sousa, et al. Horticultura Brasileira, 2022 The quality of sweet potato roots is influenced by factors which precede harvest. Thus, the aim of this study was to correctly determine the harvest point and study the postharvest quality of two sweet potato cultivars harvested at different ages. The experiment was carried out at Universidade Federal de Roraima. The plants were grown from April to August, during rainy season, 2020. The harvest was carried out at 80, 95, 110, 125 and 140 days after planting (DAP). The tuberous roots were cleaned and the physicochemical traits of the pulp and peel were evaluated. Soluble solids, titratable acidity and SS/AT ratio were observed in greater quantity in the cultivar BD-02. The luminosity and chroma of the peel of the sweet potato roots were more intense in the cultivar BD-01 and the opposite was observed when characterizing the pulp of this cultivar. At 110 DAP, we verified the highest levels of reducing sugars and chroma of the peel, as well as lower values for the chroma of the pulp and °H of the peel. Thus, according to the results presented above, especially in relation to carbohydrate metabolism, productivity and dry matter accumulation, the cultivar BD-02, harvested at 110 DAP, showed the best postharvest traits under the experimental conditions presented in this study.
Post-acidification and evaluation of anthocyanins stability and antioxidant activity in açai fermented milk and yogurts (Euterpe oleracea Mart.) DANIELA CAVALCANTE DOS SANTOS CAMPOS, LEANDRO TIMONI BUCHIDID CARMAGO NEVES, ADRIANA FLACH, LUIZ ANTONIO MENDONÇA ALVES COSTA, BEATRIZ OLIVEIRA DE SOUSA Revista Brasileira De Fruticultura, 2017 This study evaluated the post-acidification, stability of anthocyanins and antioxidant activity in açai yogurts and fermented milks for 28 days of cold storage. For the determination of post-acidification and stability of the functional properties of açai yogurt (IA) and fermented milks (LFA), products stored at 4°C were evaluated on day 0 and every 7 days for pH, titratable acidity in lactic acid, instrumental color, anthocyanins and antioxidant activity by the DPPH free radical method. Acidification of both food matrixes was more evident between days 0 and 7 of evaluation. IA presented reduction in parameter L *, while chromaticity a * and b * of IA and LFA increased as the Açai pulp content increased; however, considering the evaluation period, it was found increase in L * and b * relating to anthocyanin degradation. Anthocyanins, as well as the antioxidant activity of IA and LFA, showed an increase in their values as the pulp content increased, but their concentrations reduced at the end of the storage period. IA and LFA can be considered excellent sources of antioxidants, being alternative to individuals not used to the consumption of fruits and vegetables.
