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.展开更多

The mycelial growth rate, yield, nutritional composition and contents of heavy metals of the Pleurotus geesteranus cultivated on these substrates were determined. The results suggest that added to treated Carya cathayensis Sarg shell promoted the mycelial growth and increased the yield, biological efficiency and the contents of crude fiber, ash, amino acids and essential amino acids of Pleurotus geesteranus. In addition, the fat content and soluble sugar contents of Pleurotus geesteranus were decreased with the increase of the Carya cathayensis Sarg shell content in substrate, but their contents of heavy metals including mercury (Hg), arsenic (As), cadmium (Cd) and lead (Pb) were higher than that obtained on control substrate.展开更多
