NGHIÊN CỨU ẢNH HƯỞNG CỦA CHITOSAN KẾT HỢP ZEOLIE/CU2+ ĐẾN QUÁ TRÌNH BẢO QUẢN MÃNG CẦU DAI (Annona squamosa L.) SAU THU HOẠCH

Abstract

Sugar apples were harvested and stored immediately when they reached harvesting maturity. Sugar apples were dipped in 2% chitosan and were then air-dried. After that, they were put into the carton and placed zeolite/Cu²⁺ in a barrel and the fruit was stored at (10 ± 1)ºC in cold storage, humidity 80 - 85%. The results revealed that the preservation of the sugar apples with 5 packets (5 g/packets) of zeolite/Cu²⁺/barrel after coating them with 2% chitosan was better. Sensory and nutritional qualities of the fruits were maintained through a storage period of 12 days at 10 ºC.
