摘要
酵母细胞壁也称为酵母皮,因其独特的生理活性功能已成为葡萄酒酿造的重要辅料之一。本实验在发酵过程中添加酵母细胞壁,研究其对酵母生长代谢的影响。研究发现,酵母细胞壁能显著促进酵母的生长繁殖,在含乙醇的葡萄汁中,添加酵母细胞壁能减轻乙醇对酵母的抑制甚至毒害作用,促进酵母的生理活性及生长代谢。
Yeast cell wall, also called yeast hulls, has become one of the most important auxiliary materials in grape wine-making due to its unique physiological activities. In this study, yeast hulls was added during the fermentation of grape wine to investigate its effects on yeast growth metabolism. The results suggested that yeast hulls could significantly promote the growth and the reproduction of yeast, and the addition of yeast hulls in grape juice containing alcohol could reduce the inhibition and the toxication of ethanol on yeast and promote the physiological activities and the growth and the metabolism of yeast.
