Conservação pós-colheita de diferentes cultivares de mandioca submetidas ao processamento mínimo e congelamento

Abstract: A demanda dos consumidores por raízes de mandioca de mesa in natura está decrescendo, em função da elevada perecibilidade das mesmas e do aspecto visual pouco atrativo. Como consequência, vem crescendo a comercialização do produto minimamente processado ou processado na forma de pré-cozido, congelado e massa, tanto para o mercado interno como para exportação. O objetivo do estudo foi determinar a conservação pós-colheita de raízes de cultivares de mandioca de mesa com coloração da polpa rosada (BRS 400), amare… Show more

“…There is a relationship between increased pH and decreased titratable acidity in stored products due to the consumption of organic acids as substrates in the respiratory process (Chitarra & Chitarra, 2005). Rinaldi et al (2015a) observed a significant increase in pH values of minimally processed cassava roots conditioned with and without vacuum and stored under refrigeration and freezing (without vacuum) for cultivars IAC 576-70, BRS 400, and BRS 399, differing from that observed in this study. The pH value determines the enzymatic activity, the deterioration degree, the texture variation, the degree of maturation of fruits and vegetables, and the choice of the most appropriate packaging and storage conditions (Chitarra & Chitarra, 2005).…”

“…Throughout the storage period, the soluble solids content ranged from 6.87 °Brix to 9.57 °Brix, with an initial value of 7.00 °Brix ( Table 1). The variation in soluble solids contents during storage is influenced by intrinsic characteristics of the sample, by metabolic reactions that may occur during the storage period, using sugar as a substrate, and by microbial activity in the product kept under refrigeration (Rinaldi et al, 2015a). Thus, we can affirm that the processing, packaging, and storage conditions were adequate for the maintenance of this variable.…”

“…Segundo Rinaldi et al (2015a), o chroma define a intensidade da cor, em que valores próximos a zero são indicativos de cores neutras (branco ou cinzas) e valores ao redor de 60 indicam cores vívidas ou intensas. Os Utilização de ácido cítrico para a conservação pós-colheita de raízes de mandioca Rinaldi, M. M. et al menores valores apresentados foram de 20,44 e 20,74, determinando cores com menor intensidade da coloração intensa.…”

“…As avaliações foram realizadas aos dezoito meses após o plantio, sendo os dados submetidos à análise de variância e as médias comparadas pelo teste de Tukey. O clone 330/09 se destacou por apresentar maior INTRODUCTION Cassava is cultivated mainly for to its starchy roots, which is used in human food (RINALDI et al, 2015;RINALDI et al, 2019), animal feed (OLIVEIRA et al, 2014;GONÇALVES et al, 2015;SUDARMAN et al, 2016;, and as a raw material for various industrialized products (ZHU, 2015). This plant species displays drought tolerance and the ability to grow in acidic soils with low fertility, as well as flexibility in terms of planting and harvesting times, and in adapting very well to the climate and soil conditions of Brazil .…”
