摘  要:
本文主要研究了双歧杆菌22-5胞外多糖(exopolysaccharide,EPS)对酸奶菌种在逆境中存活率以及对酸奶质构的影响作用。结果表明:与空白对照相比,100mg/L的EPS对酸奶菌种在冷藏温度、模拟胃肠道不良环境中保护作用均不显著;12.0g/L的EPS能显著提高酸奶黏度、降低其pH值、增加其酸度,但对持水力的影响不显著。

摘  要:
The effect of exopolysaccharide (EPS) produced by Bifidobacterium 22-5 on the character of yoghourt was studied in this paper. The results showed that 100mg/L EPS affect the livability little when the bacteria was under cold storage and traveled the simulated enteron. Bisides, 12.0g/L EPS can effectively improve the viscosity and acidity, but descreased the pH value, without remarkable change of water-binding capacity.
