中国粮油学报标明显改善;但油茶籽油中的有益脂质伴随物 VE、甾醇、黄酮、多酚、类
胡萝卜素显著下降,从毛油到脱蜡油,损失率分别为 %、%、%、%、%,
特别是脱臭和脱酸两道工序影响最大;脂肪酸组成在精炼各阶段变化较小;精炼过程,理化指标
与有益脂质伴随物之间的相关性较大,与脂肪酸组成的相关性较小。因此,油茶籽油生产过程中,
减少精炼工序,改进脱酸、脱臭工艺,对较好的保留油茶籽油中的有益脂质伴随物,提高营养功
能价值具有重要作用。

Abstract Camellia seed oil samples of crude oil, deacidified oil, decolorized oil, deodorized oil and
dewaxed oil were collected from the camellia seed oil processing plant and the physicochemical
parameters, beneficial lipid concomitants and fatty acid composition of these samples were determined.
Moreover, the principal component analysis and correlation analysis of the test data was carried out to
explore the changing law of the quality of camellia seed oil during the refining process. The results
