1. Quality of potato CV. innovator submitted refrigeration and recondition
Abstract The objective of this study was to determine the storage efficiency and reconditioning of potato cv. Innovator for processing. Tubers were stored at 6, 7 and 8 °C in the dark for 30, 60, 90, 120 and 150 days and reconditioned at 15 °C for 15 days. TRS and RS were reduced as storage temperature increased from 6 + 15 °C to 8 + 15 °C. Regardless of

2. Activity of polyphenoloxidase and peroxidase in non-dormant potato tubers treated with sprout suppressors
Abstract One of the major problems affecting potatoes quality on stored is the susceptibility to enzymatic browning, which occurs mainly after wounds during the harvest, at postharvest handling and by aging, leading to the development of dark color compounds. Enzymatic browning is associated with the action of polyphenoloxidases (PPO) and peroxidases (POD),

4. The browning kinetics of the non-enzymatic browning reaction in L-ascorbic acid/basic amino acid systems
Abstract Under the conditions of weak basis and the reaction temperature range of 110-150 °C, lysine, arginine and histidine were reacted with L-ascorbic acid at equal amount for 30-150 min, respectively and the formation of browning products was monitored with UV–vis spectrometry. The kinetic characteristics of their non-enzymatic browning reaction were

5. Avaliação da vida util de manga (Mangifera indica cv Tommy Atkins ) minimamente processada pre-tratada com acido citrico e coberturas comestiveis / Evaluation of the shelf-life of minimally processed mango (Mangifera indica cv Tommy Atkins ) pre-treated with citric acid and edible coatings
Mango is a widely grown and consumed fruit in Brazil, being also exported `in natura¿ to many different countries. Fresh-cut mangoes, in spite of their practicity, may have enzymatic browning and unpleasant changes of texture. Thus, this work aimed to study the shelf-life of mango slices (Mangifera indica cv `Tommy Atkins¿) pre-treated with citric acid and

6. Evaluation and optimization of non enzymatic browning of “cajuina” during thermal treatment
"Cajuina" is a very popular drink in the Brazilian northeastern region and is produced by clarifying cashew apple juice. To preserve "cajuina" from chancing, the clarified cashew apple juice is submitted to thermal treatment where a desired final color should be obtained. To optimize color formation while maintaining high vitamin C and low 5-hydroxymethylfur

7. Respostas fisiológicas e bioquímicas de diferentes cultivares de batatas ao processamento mínimo / Physiological and biochemical responses of different potato cultivars to minimal processing
The purpose of the present work was to evaluate physiological and biochemical aspects of minimally processed Agata, Asterix and Monalisa potato cultivars. First physiological and microbiological variables of fresh-cut potatoes stored at 5, 15 and 25ºC were evaluated. Potatoes Asterixshowed the highest respiratory rates when compared to potatoes cv. Agata an

8. Estudo das interações polifenol-proteína e das reações de escurecimento não-enzimático para o processamento de cajuína
O caju, frutífera originária do Nordeste brasileiro é utilizado para produção de suco devido ao seu sabor e ser rico em vitamina C. Entretanto, sua aceitação é limitada devido a sua adstringência. Um produto bastante apreciado pelo seu sabor característico, refrescante e não adstringente, devido à remoção dos taninos, é a cajuína. A cajuína
