The postharvest maintenance quality of fruits is significant for industrial applications. The present study was conducted to evaluate of quality parameters and bioactive components of seedless lime (Citrus latifolia) fruit during cold storage. Lime fruits were packed in perforated polyethylene bags, which were then put into a perforated expanded polystyrene box, and stored in a cool chamber, at 10°C. Quality parameters including skin color, weight loss, total soluble solids (TSS), juice percentage, technological index, titratable acidity (TTA), reducing and total sugars of the fruits were measured during 56 days of storage. The total phenolic content of the juices was measured using a colorimetric method of Folin-Ciocalteu. Ascorbic acid and major flavonoids of the fruits such as hesperidin and eriocitrin were quantified using HPLC-PDA methods. The results showed that cold storage kept the greenness of the fruit’s skin for up to 28 days. A minor weight loss (< 5%) was also recorded in the first 28 days of storage. The technological index of the fruits, reducing total sugars and TSS slightly increased, whereas TA somewhat decreased. Bioactive components such as phenolic and ascorbic acid contents were kept stable (p>0.05) in the first 21 days of storage but considerably reduced after 28 days of storage. A decrease in hesperidin and eriocitrin was also recorded from 21 days of storage but at a lower rate compared to that of phenolic and ascorbic acid contents. Altogether, a simple, convenient cold storage method using a perforated polyethylene bag and expanded polystyrene box can retain the quality and bioactive components of lime fruits for at least 21 days. The findings are significant for the food industrial application of storage lime fruits for fresh utilization or juice processing.
