中文摘要: 硒(selenium,Se)是人体必需的微量元素之一,具有抗氧化、抗癌、抗菌、增强免疫力等功能。通过在牛奶中添加硒化合物经乳酸菌发酵形成营养价值和安全性高的富硒酸奶。从富硒酸奶的发酵条件、理化性质、硒的化学形态以及生物活性等方面进行综述,并对可以基于生理代谢途径和现代分子技术开展的乳酸菌转化牛奶中硒的代谢机理研究进行展望。
Abstract:Selenium(Se),a critical micronutrient for the human body,has multiple effects,such as anti-oxidation,bacterial resistance,anti-cancer,and immunity improvement.Selenium-enriched yogurt with high nutritional value and good safety was prepared from milk added with Se compound by lactic acid bacteria fermentation.The present study reviewed the fermentation conditions,physical and chemical properties,chemical forms of Se,and biological activity of selenium-enriched yogurt,and prospected the research on the metabolic mechanism of Se in milk transformed by lactic acid bacteria based on physiological metabolic pathways and modern molecular technologies.
