Research progress on the mechanism of anti-aging evaluation system for Lactic acid bacteria

Abstract

Lactic acid bacteria (LAB) is the general name of a class of bacteria that can ferment sugars to produce acid and gas. Lactobacillus has rich species diversity and geographical distribution, including at least 18 genera and more than 200 species. It is widely used in food, animal husbandry, medicine, and other fields. In recent years, due to LAB’s excellent antioxidant and anti-aging properties, the research and development of corresponding functional products have become hot spots in various fields. Focusing on the excellent characteristics of antioxidation and anti-aging of LAB, this paper summarizes the evaluation system and analysis of effective active substances that can be used for screening anti-aging in order to provide the theoretical basis for screening functional LAB.
