Strawberry is a non-climacteric fruit but exhibits very limited postharvest life due to rapid softening and decay. Therefore, the current study was carried out to evaluate the effects of different types of edible coatings to extend the postharvest life of strawberry fruit. The strawberry fruits of cultivar Chandler, grown under agro-climatic conditions of Multan, were coated with Aloe vera gel, chitosan (2%) or sodium alginate (2%) and kept in refrigerated storage at 5-7 °C with 50-60% RH for 12 days. The fruits were evaluated for sensory and biochemical quality attributes after every 4 days of storage. The results showed that overall coated fruits had prolonged storage life (8 days) as compared to non-coated fruits (4 days). Aloe vera gel coating maintained various quality attributes of strawberry fruits such as firmness, appearance, TSS (6.8°Brix), titratable acidity (1.14%), pH (3.27), ascorbic acid content (76 mg 100 mL-1), antioxidant activity (93%), anthocyanins (104 mg PE 100 g-1 FW) and total phenolic content (369.45 µg GE mL-1). Generally, all coatings prohibited the decay incidence. The results showed that edible coatings based on Aloe vera gel can be used as an effective alternative for other costly and synthetic chemicals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
