Abstract:

The effects of different gas composition storage on physiological changes and quality of Dog-head jujube fruit were studied. Shaanxi Yan’an Dog-head jujube was selected as the material to investigate the respiration type, and the storage effect of different gas ratios on the content of sugar, acid, vitamin C (VC) and the activity of main enzymes. The sensory evaluation was carried out after the storage. Results showed that Dog-head jujube was non-climacteric fruit. The ratio of 10%O2+90%N2 gas could slow down the decreasing rate of fruit hardness and titratable acid content, maintain the content of reducing sugar and VC, inhibit the activities of polygalacturonase (PG), peroxidase (POD) and polyphenol oxidase (PPO), and enhance catalase (CAT) activity. The fresh fruit was stored under the condition of low temperature of -1~0 ℃, relative humidity of 90%~95% and gas ratio of 10% O2+90% N2 for 80 d. After storage, the good fruit rate was 88.6%, freshness index was 0.59, and sensory evaluation quality was good.

Key words: Dog-head jujube, respiration type, controlled atmosphere storage, physiological changes, storage quality
