چکیده مقاله:

Purpose: The main aim of this study was to evaluate the changes in quality of minimally processed litchi fruit during storage at low temperatures (۵-۷°C). Research method: The study attempts to report the efficacies of seven different anti-browning compounds at various concentrations namely methionine (۰.۱%), cysteine (۰.۱%), EDTA (۰.۱%), oxaloacetic acid (۱%), ascorbic acid (۱%), citric acid (۱%), and potassium metabisulfite (۰.۵%) on quality and shelf-life extension of minimally processed litchi aril. Treated litchi aril kept in trays wrapped with plastic film and stored under refrigerated conditions. Changes in total soluble solids, titratable acidity, ascorbic acid, total phenolics, sensory attributes, colour, weight loss, microbial and activities of polyphenol oxidase and peroxidase enzymes were evaluated. Findings: Treatments reduce the weight loss and sensory attributes with higher contents of TSS, titratable acidity, ascorbic acid, total phenolics and suppressed the increase in activities of polyphenol oxidase and peroxidase. Therefore, a postharvest dip of peeled litchi into solutions of chemical preservatives could be suggested to maintain the postharvest quality under refrigeration storage. Treated litchi arils were acceptable (sensory score >۷) up to ۸ days as compared to ۳ days for the control samples during refrigerated storage. Research limitations: No limitations were found. Originality/Value: Further, ۱% ascorbic acid and ۱% citric acid were recorded to be the best to preserve the quality of minimally processed ‘Mujaffarpur’ litchi during refrigeration storage.
