食品中胆固醇的检测与脱除技术研究进展

Research progress on the detection and removal technology of cholesterol in food

胆固醇不仅是细胞膜和脂蛋白中重要的脂质分子,也是固醇激素、胆汁酸和维生素D的前体,其与人体健康息息相关。胆固醇除了人体自身合成外,也可从动物源食品中获取。胆固醇是人体生理必需的,但胆固醇摄入过多会提高患胆结石、冠心病、脑血栓等相关疾病的风险。因此必须准确定量这些食品中的胆固醇,并对部分食品中的胆固醇进行脱除。该文综述了食品中胆固醇的检测与脱除技术,总结了各种技术的特点与应用,并展望了未来食品中胆固醇的检测与脱除技术发展方向,以期为该领域研究工作提供参考。

Known as an important lipid molecule in cell membranes and lipoproteins,a precursor of steroid hormones,bile acids,and vitamin D,cholesterol is closely associated with human health.In addition to the body’s own synthesis of cholesterol,all other required cholesterol must be obtained from animal foods.Cholesterol is essential for human physiology,but excessive cholesterol intake increases the risk of gallstones,coronary heart disease,cerebral thrombosis,and other related diseases.It is important to accurately quantify the cholesterol in these foods and remove it from some kinds of foods.This review examined the detection and removal techniques of cholesterol in foods,summarized the current characteristics and applications of various techniques,identified and recommended future work in the development of cholesterol detection and removal techniques in foods.
