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

[Method] 50 male mice were divided into 5 groups equally and randomly and among them,the three groups were either negative,or model control,or positive control (ginseng saponins),respectively. Two remaining groups were orally fed with low and high dosages of CCS oil ((9 ml/(kg·d) and (33 ml/(kg·d)),respectively. All groups were injected D-galactose through hypodermic except the negative control ones which were only treated with equals amount of distilled water. The superoxide dismutase (SOD),maleic dialdehyde(MDA) and monoamine oxidase(MAO) were analyzed with blood sample and brain tissue 42 days post treatment. [Result] It was showed that the activity of SOD enzyme was increased in the CCS oil groups,while MDA and MAO content were decreased in the CCS oil groups compared with that of other groups with significance observed in the group fed with high dose of CCS oil. [Conclusion] The result indicated that the CCS oil has the ability of antioxidation and is useful to human health.展开更多

According to the survey,it made an in-depth analysis on brand positioning strategy for Lin'an Carya Cathayensis Sarg,and obtained the existing brand operating model. It is hoped to explore effective strategy of brand positioning for agricultural product enterprises in Zhejiang Province,and accordingly lift core competitiveness of agricultural products of Zhejiang Province.展开更多

The experimental results indicated that the main components of the three kinds of raw materials consisted of cellulose, hemicellulose, and lignin. The highest contents of hemicellulose, cellulose, and lignin were in Camellia oleiferaAbel shells (49.34% ± 0.07%), Castanea mollissima Blume shells (27.34% ± 0.01%), and Carya cathayensis Sarg shells (49.78% ± 0.01%), respectively. The pyrolysis processes of three kinds of shells generally included three stages, namely dehydration, pyrolysis, and carbonization. The peak values and the appearance times of their pyrolysis rates were closely related to their compositions.展开更多
