Research Progress on Polysaccharide Components of Wine Grape Cell Wall
Wine grape cell wall ripening involves the structural regulation of a number of polysaccharide macromolecules,such as pectin,cellulose,hemicellulose,etc.Meanwhile,wine grape varieties,cultivation treatments and climatic factors also affect the structural evolution of cell wall polysaccharides during the fruit ripening process.The structural changes of cell wall polysaccharide components during wine grape ripening and vinification will affect the quality of wine.This paper summarizes the structural micro-modification mechanism of cell wall polysaccharide components during the ripening process of wine grape berries,discusses the effects of grape variety,climate,and cultivation treatments on wine grape berry cell wall polysaccharides,and summarizes the degradation mechanism of cell wall polysaccharides under different technological treatments in the vinification process in order to provide theoretical references for further study of wine grape berry cell wall polysaccharides.
