摘　　要：以葵花籽油为标准进行21 d的大鼠生长试验,评价了含30%山嵛酸的低热量油脂的可用热量,得到其可用热量为25.8 kJ/g,与葵花籽油37.8 kJ/g相比降低了31.75%。添加5%、15%山嵛酸低热量油脂中未被吸收的山嵛酸分别为73.53%和81.24%。动物试验结果表明,山嵛酸低热量油脂对大鼠血清中的TG、TC、HDL-C、LDL-C以及AI值和AII值的影响与葵花籽油类似,不会升高发生动脉硬化的风险。The caloric availability of reduced - calorie fat containing behenic acid was estimated by a restricted diet growth experiment over 21 d on SD rats with sunflower seed oil as a caloric control. The result showed that the caloric availability of the reduced - calorie fat containing 30% behenic acid was 25.8 kJ/g. Compared with sunflower seed oil,the calorie availability decreased by 31.75%. The unabsorption behenic acid added with 5% and 30% reduced - calorie fat containing behenic acid were respectively 73.53% and 81.24%. The serum lipid levels of rats before and after experiments showed that effects of reducedcalorie fat on serum lipid levels,such as TG, TC,HDL-C, LDL-C,AI and All, were similar to the sunflower seed oil,and the risk of atherosclerosis was not increased.
