Rats were fed with semisynthetic feeds prepared with high temperature rapeseed meal, high temperature alcohol washed rapeseed protein concentrate, high temperature alcohol washed soybean protein concentrate and low temperature alcohol washed soybean protein concentrate as the main protein sources respectively. The growth, physiological and biochemical indexes of rats were detected and analyzed to compare the effects of different protein sources so as to evaluate the nutritional function of high temperature alcohol washed rapeseed protein concentrate. The results showed that according to the comprehensive comparisons of the growth, digestion and metabolism, blood routine and blood biochemical indexes of rats and nutritional value of protein, the group of high temperature alcohol washed rapeseed protein concentrate was the best, followed by the groups of high temperature rapeseed meal, low temperature alcohol washed soybean protein concentrate and high temperature alcohol washed soybean protein concentrate; the levels of aminotransferase (ALT), uric acid (UA) ,triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) of rats in the group of high temperature alcohol washed rapeseed protein concentrate were the lowest, and anti-atherosclerotic index (AAI) of rats was the highest among the four groups, which indicated that the rats in the group of high temperature alcohol washed rapeseed protein concentrate had lower risk of diabetes and atherosclerosis than the other three groups. Therefore, high 〖HJ〗temperature alcohol washed rapeseed protein concentrate was a high-quality feed protein source. |
