| 摘 要： | 通过对不同冻藏时间下馒头品质和淀粉回生进行研究，探讨了木聚糖酶对冷冻馒头品质及抗老化作用的影响。结果表明，添加了木聚糖酶的馒头样品在冻藏期间的感官得分、弹性、水浸提物含量均高于对照组。冻藏48 h内，随着木聚糖酶添加量的增加，馒头的感官得分、冷冻面团水分含量呈现出先上升后下降的趋势；馒头老化速率相对较快，但随着时间的延长，老化现象减弱，基本趋于稳定。木聚糖酶可作为延缓冷冻馒头老化的有效添加剂。

| Abstract: | This study aimed at evaluating the quality of steamed bread under different freezing storage times, and the effect
of xylanase on anti-aging of frozen steamed bread was also investigated. Results showed that the sensory analysis, elasticity
and water extract content of bread containing xylanase was higher than those of control. The sensory scores and water extract
content of frozen dough increased than decreased with increasing addition of xylanase. Aging rate of steamed bread was
relatively higher within 48 h, but then gradually decreased and tended to be stable. Xylanase could be used as an additive for
delaying the aging process of frozen steamed bread. |
