ABSTRACT: Carya
cathayensis Sarg is distributed near Tianmu mountain areas in Zhejiang Province and Anhui
Province, China. Kernel of Carya cathayensis Sarg, which is well-known for the
daintiness and nutritional content, is popular and very delicious
food in eastern China. In this paper, we investigated the physiochemical
properties and nutrient gradients of the kernel oil of Carya
cathayensis Sarg. The results showed that the kernel oil of Carya
cathayensis Sarg contained 63% of fat, 9.1% of proteins, 3.6% of
starch and 4.6% of soluble proteins (based ration of weight). The compositions
of the fatty acids were very similar to olive oil, and the total unsaturated
fatty acids were 94%. Meanwhile, the kernel oil of Carya cathayensis Sarg also contained some polyphenols such as vanillic acid, ferulic acid,
3-methoxybenzoic acid and quercetin. The content of total polyphenols was 9.7
μg/g. Furthermore, the kernel oil of Carya cathayensis Sarg also contained some trace amount of squalene, β-Sitosterol, Vitamin E.
