Abstract:Yellow wine lees is a solid product obtained from the solid-liquid separation after the fermentation of rice wine mash, containing abundant proteins. Proteins have physico-chemical properties such as emulsifying and foaming properties. Adding them to food can affect food’s color, flavor, appearance, texture, and other qualities; Proteins can also be used to prepare active peptides, such as antihypertensive peptides and antioxidant peptides. These peptides can be used as functional ingredients in functional foods and health products. However, most of the industries treat yellow wine lees as waste or feed with low added value, and the development and utilization of protein resources in them are insufficient. This article reviews the latest research progress in the preparation methods, physicochemical properties, and potential for preparing active peptides of yellow wine lees protein. The gaps of the current research on yellow wine lees protein and future research directions are analyzed. The potential application value of yellow wine lees protein in the food field is discussed, in order to provide a reference for the high-value utilization of yellow wine lees protein resources.
