摘要
为了提高冷冻面团馒头品质,探讨制作工艺(酵母添加量、加水量、速冻温度、速冻时间、醒发温度、醒发时间)对冷冻面团馒头品质的影响。采用Plackett-Burman设计和最陡爬坡试验筛选出影响冷冻面团馒头品质的关键工艺因素及其最大响应区域;采用Box-Behnken响应面优化冷冻面团馒头发酵工艺。结果表明最佳的发酵工艺条件为:酵母添加量0.8%、醒发温度37.5℃、醒发时间29.6 min,在此条件下,冷冻面团馒头的发酵力为(1.52±0.13)g、硬度为(2 074.67±72.71)gf,与预测值接近,能改善冷冻面团馒头品质。该研究结果为冷冻面团馒头品质提升及其产业化发展提供科学依据。
In order to improve the quality of frozen dough steamed bread,the effect of processing technology on the quality of frozen dough steamed bread was discussed. Fermentation process included yeast addition,water addition,frozen temperature,frozen time,fermentation temperature and fermentation time. Then,we screened out the key technological factors affecting the quality of frozen dough steamed bread and the maximum response area by Plackett-Burman design and steepest ascent desgin. Finally,We optimized the processing technology of frozen dough steamed bread by Box-Behnken test. The results showed the optimum processing technology were as follows：0.8 % yeast addition,37.5 ℃ fermentation temperature,29.6 min fermentation time. Under this condition,the fermenting force of the frozen dough steamed bread was（1.52 ±0.13） g and the hardness was（2 074.67±72.71）gf,which was close to the predicted value,and it could improve the quality of the frozen dough steamed bread. The results provided scientific basis for improving the quality and industrialization of frozen dough steamed bread.
