Abstract:

In order to evaluate the performance of different varieties of Camellia oleifera seeds in Youyang region, the economic characteristics, bioactive ingredient content, and fatty acid composition of Camellia oleifera seed varieties including Changlin 3, Changlin 4, Changlin 40, Changlin 53, Xianglin 210 were studied. The results showed that there were differences in the economic characteristics, bioactive ingredient content, and fatty acid composition of Camellia oleifera seeds from different varieties in the Youyang region. Among them, air-dried seeds of Changlin 3 had the lowest water content. Changlin 40 had the highest kernel yield, and Changlin 3 had the highest kernel oil content. Changlin 53 has the highest content of squalene, and Changlin 3 has the highest content of β-sitosterol. The highest content of total polyphenols was Changlin 4. The highest content of vitamin E was Changlin 40. The largest proportion of unsaturated fatty acids was Changlin 53. The highest proportion of α-linolenic acid was Changlin 4. The results of this study provide a reference for the planting and processing of Camellia oleifera in Youyang and surrounding areas.
