中文摘要:

      食用植物油是人体生命活动和机体代谢过程中不可或缺的物质, 不仅为人体提供能量、必需脂肪酸, 还含有植物甾醇、维生素E、多酚、角鲨烯和类胡萝卜素等多种营养功能成分。研究表明, 植物甾醇具有降低胆固醇水平、抗动脉粥样硬化和抗肿瘤等功能; 维生素E可以抑制油脂过氧化, 增加机体免疫能力, 预防和治疗心血管疾病等; 多酚具有消炎、预防冠心病等功能; 角鲨烯具有促进血液循环、活化机体细胞等功能。本文主要对植物油中的营养成分及相应检测技术进行了简要综述, 旨在促进植物油营养成分的深入研究, 挖掘食用油潜在营养成分和价值, 为指导消费者合理使用食用油提供科学依据。

英文摘要:

      Edible vegetable oil is indispensable for human life activities and metabolism, which not only provides energy and essential fatty acids, but also nutritional and functional components such as phytosterols, tocopherols, polyphenols, squalene and carotenoids for human. Studies show that phytosterols have functions like reducing cholesterol levels, resistance to atherosclerosis and antitumor and so on. Vitamin E can inhibite lipid peroxidation, increase the body's immune ability, prevent and treat cardiovascular diseases, etc. Polyphenols have functions such as anti-inflammatory and prevention of coronary heart disease. Squalene can promote blood circulation and activate the body's cells, etc. Therefore, this review summarized the nutritional components of vegetable oils and their analytical techniques, so as to promote the further study of nutrients in vegetable oil, mine potential nutritive value of edible oils, and provide scientific basis for the rational use edible oils of consumers.
