Abstract

Alkali extraction technology of water insoluble protein from tea was studied. The extracting rate of tea protein was around 61.1%. The crude tea protein was prepared by adjusting pH of the extract and its purity was 54.45%.The effects of water insoluble tea protein on decreasing blood lipids were studied on the hyperlipidemia rats. Results showed that the protein had significant effects on decreasing TC、TG、LDL-C、AI and R-CHR in the hyperlipidemia rats(p<0.05). It could also modulate the HDL-C indexes. The results confirmed that the water insoluble tea protein had remarkable effects on decreasing the blood lipid of hyperlipidemia and possibly is preventing atherosclerosis and coronary heart disease.

Key words
