通过正交试验设计和感官评分,选用不同的发酵剂添加量(A)、发酵温度(B)和时间(C)、液体麦精量(D),采用四因素三水平进行正交试验,以产品的感官评分为评价指标,筛选出因素水平最佳组合。结果显示:因素影响排序为:A>D>C≈B;格瓦斯酸奶的最佳工艺参数为A2B1C3D3,即发酵剂添加量0.004%,发酵温度28℃,发酵时间14 h,液体麦精添加量3%。经生产验证,上述较佳因素水平组合能够获得细腻柔软的凝乳,并带有独特开菲尔风味及温和烤面包风味的饮用型格瓦斯酸奶。
通過正交試驗設計和感官評分,選用不同的髮酵劑添加量(A)、髮酵溫度(B)和時間(C)、液體麥精量(D),採用四因素三水平進行正交試驗,以產品的感官評分為評價指標,篩選齣因素水平最佳組閤。結果顯示:因素影響排序為:A>D>C≈B;格瓦斯痠奶的最佳工藝參數為A2B1C3D3,即髮酵劑添加量0.004%,髮酵溫度28℃,髮酵時間14 h,液體麥精添加量3%。經生產驗證,上述較佳因素水平組閤能夠穫得細膩柔軟的凝乳,併帶有獨特開菲爾風味及溫和烤麵包風味的飲用型格瓦斯痠奶。

Through orthogonal experimental design and sensory evaluation, use of different dosage fermentation culture(A), fermentation temperature(B)and time(C)and the amount of liquid malt extract(D), four factors and three levels orthogonal design experiments and the sensory evaluation of products as evaluation criteria, to selected horizontal preferred combination of factors. The results shows that the order of factors affecting as A> D> C ≈ B, optimum process parameters of kvass yogurt is A2B1C3D3, namely as fermentation culture in an amount of 0.004%, fermentation temperature at 28 degrees, fermentation time with 14 hours, and liquid malt extract was 3%. Production-proven, above the level of factors that can get better delicate soft curds with a unique keifr lfavor and mild toasted bread lfavor of kvass yogurt.
