| 中文摘要: |
| 反式脂肪酸是脂肪酸链上至少含有1个非共轭反式双键的不饱和脂肪酸异构体。反式脂肪酸（C18）会提高血液胆固醇水平，增加心血管疾病的风险，给人体造成不利的影响。EPA/DHA是重要的长链多不饱和脂肪酸，具有多种生物活性，对维持人体健康具有重要意义。EPA/DHA在精炼加工过程中会发生反式异构化。与全顺式EPA/DHA相比，反式EPA/DHA的生理功能发生了显著变化。从反式EPA/DHA的来源、检测技术、生理功能等方面进行了综述，以期为EPA/DHA的综合开发利用提供科学依据和理论基础。 |
| 英文摘要: |
| Trans fatty acids are unsaturated fatty acid isomers containing at least one non-conjugated trans double bond in the fatty acid chain. Trans fatty acids (C18) can increase blood cholesterol levels and the risk of cardiovascular disease, which cause adverse effects on the human body. EPA and DHA are important long-chain polyunsaturated fatty acids with a variety of biological activities and they are of great significance for maintaining human health. EPA and DHA will undergo trans-isomerization during the refining process. Compared with cis EPA and cis DHA, the physiological functions of the trans EPA and trans DHA have undergone significant changes. The sources, detection technology and physiological function of trans EPA and trans DHA were reviewed in order to provide a scientific basis and theoretical basis for the comprehensive utilization and development of EPA and DHA. |
