| Abstract | The shelf life and quality changes of lime under low temperature storage (10±1°C) and ambient temperature was investigated. Edible wax (STA-FRESH 360HS™) and 0.5% (w/v) of chitosan were coated on the lime and compared on the effects of low temperature storage. Controlled atmosphere storage (CA) at 10±1°C, 90%RH with six combinations of C02 and 02 namely 5%02+2%C02, 5%02+5%C02, 5%02+8%C02, 10%02+2%C02, 10%02+5%C02, 10%02+8%C02. Lime was analyzed for weight loss, colour changes, pH, titratible acidity, and total soluble solids during storage under each condition. Results of storage temperature revealed that lime could be kept under ambient condition for 8 days and 18 days under low temperature. Lime under various controlled atmospheric conditions for 50 days, at 5%02+2%C02 showed a good appearance, changed in colour and decay was not observed. 15% of weight loss of fruits stored at ambient temperature was highly increased when compared with fruit stored with low temperature and final day of storage weight loss reached 15%. Weight loss of fruit stored under CA condition at day 50, was 3.2% for 5%02+8%C02 while the remaining conditions were 1.4,1.9,1.4,1.5, and 1.8, for 5%02+2%C02, 5%02+S%C02, 10%02+2%C02, 10%02+S%C02, and 10%02+8%C02, respectively. Compositional of fruit all treatments were showed slightly different among the values due to storage time. CA storage delayed yellowness and weight loss significantly (P=0.05) as compared to air storage of uncoated fruit in air atmosphere. At high C02 storage (5%02+8%C02) fruit gave the most decay, on the contrary the high 02 composition ( 10%02+ 2%C02) showed the highest yellowness. |
