摘要: 以陕西临潼净皮甜石榴为试验材料,研究了不同温度和气体成分条件下石榴贮期生理变化特性,通过对其外观色泽和内部籽粒品质比较,获得了理想的适温气调保鲜技术参数:贮藏温度4~5℃,相对湿度90%~95%,气体成分O2=3%、CO2=3%,在此条件下贮藏石榴100d,可溶性固形物含量14.2%,总酸含量0.384%,果皮褐变指数0.12,果实腐烂率3.5%,贮后果实色泽鲜艳,籽粒晶莹剔透,风味酸甜适口。

Abstract:  Physiological changes during storage of Shaanxi Lintong sweet pomegranate under different temperatures and gas components were studied in this paper. Optimum technical parameters of controlled atmosphere storage at appropriate tem- perature were obtained by comparison of skin appearance and seed quality. After 100 days of storage under the conditions of 4~5℃, 90%~95% relative humidity, and 3%O2 and 3%CO2 gas component, the soluble solids content of pomegranate was 14.2%, titratable acidity 0.384%, browning index of husk 0.12 and rotten rate of fruits 3.5%. The fruits remained in satisfactory state afters torage.

Key words: pomegranate, appropriate temperature, controlled atmosphere, storage
