中文摘要: 研究温度、光线、容器材质 3 个因素对油茶籽油贮藏效果的影响,主要包括测定茶油皂化值、酸值、碘值、过氧 化值 4 个指标。试验结果表明无论在哪种情况下,皂化值、酸值、过氧化值都随贮藏时间的延长而增加,碘值减小,但在 冷藏、避光、玻璃包装条件下的茶油的指标值变化率较小,即酸败得较慢,不容易变质。所以得出茶油较佳的贮藏条件是 冰箱、避光、玻璃容器贮藏。
中文关键词: 油茶籽油  贮藏  茶油品质
Abstract:Studying the effects of three factors of temperature, light, container material on the camellia seed oil storage,essentially,the four indicators of tea saponification value, acid value, iodine value, peroxide value were determined.The results showed that no matter what the case was, saponification value, acid value, peroxide value increased with the extension of storage time, the iodine value decreased, however, the rate of changing of the in- dex value of tea under the condition of refrigeration, dark, glass packaging was smaller, was rancidity slower, not perishable. So better storage conditions of tea were concluded:refrigerator, dark, glass container storage.
