摘要
通过酵母菌、保加利亚乳杆菌、嗜热链球菌发酵制备非油炸方便面,通过复水测试、质构分析、电子鼻分析、扫描电子显微镜观察等探讨复合菌发酵工艺对非油炸方便面品质的影响。结果表明,酵母菌主要对样品的复水性和质构产生影响,保加利亚乳杆菌、嗜热链球菌主要对风味起到改善作用。一次发酵工艺有利于维持非油炸方便面的耐泡性,二次发酵工艺有利于改善复水性和风味。经过二次发酵,非油炸方便面的最佳复水时间可缩短到4.0 min,复水后样品的R(2)、R(7)的响应值高达2.8和2.9。由扫描电子显微镜观测结果可知,复合菌发酵能够赋予非油炸方便面疏松多孔的内部结构,其中二次发酵样品的孔隙分布更为均匀。综合评价非油炸方便面的品质,一次发酵、二次发酵工艺中复合菌的适宜添加量均为1.5%酵母菌+0.075%保加利亚乳杆菌+0.075%嗜热链球菌。
The effects of mixed culture fermentation with yeast,Lactobacillus bulgaricus and Streptococcus thermophilus on the quality of non-fried instant noodles were studied by rehydration test,texture analysis,electronic nose analysis and scanning electron microscopic(SEM)observation.The results showed that yeast largely affected the rehydration property and texture,while L.bulgaricus and S.thermophilus were mainly responsible for improving the flavor of non-fried instant noodles.The primary fermentation process was conducive to maintaining the cooking tolerance of non-fried instant noodles,while the secondary fermentation process was beneficial to improve the rehydration property and flavor,reducing the rehydration time to 4.0 min;the R(2)and R(7)responses of the rehydrated sample were 2.8 and 2.9,respectively.The SEM results showed that the samples had a uniform pore distribution after the secondary fermentation.Taken collectively,the optimal starter culture for the primary and secondary fermentation was 1.5%yeast+0.075%L.bulgaricus+0.075%S.thermophilus.
