提高油茶籽油中油酸含量的工艺研究

Technology for increasing oleic acid content in camellia oil

摘要: 对油茶籽油进行不同组别的天然抗氧化剂抑制油酸氧化的试验，并进行了采用不同有机膜材料脱胶提高油酸含量的L₉(3⁴)正交试验。试验结果表明：采用0.015% 维生素C+0.02％维生素E+0.02%柠檬酸的复合天然抗氧化剂，可使油酸含量达82.3%；采用有机膜材料—聚丙烯膜可使磷脂胶束脱除率达99.6%，使最终产品的油酸含量达82.6%。

Abstract: Experiment of oleic acid oxidation-restraining in camellia oil by various groups of natural antioxidants and L₉(3⁴) orthogonal experiment on enhancing oleic acid content by different organic membranes were carried out. Results indicated that the oleic acid content increase to 82.3% by compound antioxidant of 0.02% vitamin E, 0.015% vitamin C, 0.02% lemon acid added in camellia oil; 99.6% lecithin can be degummed by organic membrane—polypropylene membrane, and oleic acid content of the product can be increased to 82.6%.
