摘　　要：有机凝胶剂可以为液体油提供类似于固体流变学特性的功能,因此近年来在食用油脂的结构化中的研究日益广泛。通过大鼠喂养试验,研究和评价β-谷甾醇和γ-谷维素键合物的植物甾醇凝胶剂对包括心血管疾病高风险因子在内的动物营养生理功能的影响。结果表明,有机凝胶剂β-谷甾醇和γ-谷维素键合物人造奶油产品对动物机体不会产生不良影响;当饲料中含有β-谷甾醇和γ-谷维素键合物的植物甾醇型凝胶化特种油脂产品时,试验组大鼠的体重均低于对照组,且高剂量组大鼠体重最低,同时数据显示甾醇型有机凝胶剂量的增加使大鼠睾肾部位容易产生脂类堆积;大鼠的血清总胆固醇、三酰甘油和低密度脂蛋白水平均随着有机凝胶添加量的增加而呈现降低的剂量效应,显示其具有较好的抗动脉硬化风险作用。Organogel can solidify and trap liquid oil and shows a solid-like rheological property, and the application of organogels to structure liquid oils has become an active area of research in the past years. In this study, we examined the effect of bonding mixture of β-sitosterol ＆ γ-oryzanolas as organogel on animal nutrition physiological function by the rat feeding test, including the high risk factor of cardiovascular disease. With feed of margarine structured by bonding mixture of β-sitosterol and γ-oryzanolas, there was no adverse effects on rats. The re-sults showed that, rat body weight of experimental groups was lower than the control group,and the high dose group was the lowest. Meanwhile, the data implied that the increasing dose of sterol organogel can promote accumulation of adipose tissue in the part of testosterone and kidney of rats. In addition, the rats serum total cholesterol, triglyceride and low density lipoprotein levels were decreased with the increasing amount of organogel, which indicated that sterol organogel had better effect on the risk of antiatherosclerosis.
