摘要:
为了提高油茶籽的综合利用价值,克服传统高温热榨和精炼导致茶籽油的一些营养成分和固有香味的损失,一种双螺杆冷榨茶籽油的生产工艺被开发。中试生产试验结果表明,当入榨油料含水率6.0%,仁中含壳率8.0%时,最大榨膛温度不超过60℃,饼中残油率为3.6%,所生产的冷榨茶籽油达到国标压榨成品油茶籽油一级标准。与传统的精炼茶籽油相比,冷榨茶籽油中维生素E质量分数大大高于精炼油(P
摘要(英文):
The oil camellia (Camellia oleifera Abel., Theaceae) is notable as an important source of edible oil (known as tea oil or camellia oil) obtained from its seeds in China. Camellia oil with high oleic acid content is coming more into the focus of interest in recent years since the fatty acid composition is more comparable to olive oil. Another important aspect is that the high content of oleic acid results in a high oxidative stability, making this oil interesting for a wide range of applications. Traditional processing of camellia oil extraction is carried out by seed preparation, cooking, hot ...
