摘要
以新鲜油茶籽为原料,对比研究了自然晾晒、快速烘干和慢速烘干三种处理方式对油茶籽品质(脂肪含量、蛋白含量等)和油茶籽油品质(酸价、过氧化值、脂肪酸组成、甾醇、生育酚等)的影响。结果表明:慢速烘干处理油茶籽含油率(33.3%)和油茶籽油得率(22.4%)最高,自然晾晒处理的油茶籽油酸价(0.56 mg KOH/g)最小、总生育酚含量最高(215.22 mg/kg),快速烘干处理的油茶籽油总甾醇含量(420.88 mg/100 g)最高,上述结果为油茶籽加工提供理论参考。
The effects of natural drying,flash drying and slow drying on the quality of camellia seeds(fat content,protein content,etc.)and the quality of camellia seeds(acid value,peroxide value,fatty acid composition,sterol,tocopherol,etc.)were studied using fresh camellia seeds as raw materials.The results showed that the oil content(33.3%)of camellia seeds and the production rate of camellia seed oil(22.4%)under slow drying were the highest,the oleic acid value(0.56 mg KOH/g)of camellia seeds under natural drying was the lowest,and the content of total tocopherol obtained by natural drying was the highest(215.22 mg/100 g),and the content of total sterol obtained by flash drying was the highest(420.88 mg/100 g)in the three drying methods.The above results provide theoretical reference for the processing of camellia oil seed.
