摘要(Abstract)：

为了促进中韩自由贸易协定(Free Trade Agreement,FTA)签订之后我国大豆发酵食品的正常贸易和实现延边地区传统大酱的产业化生产,本研究在延边地区收集了11份传统酱坯,进行了理化特性、淀粉酶和蛋白酶活力以及微生物学特性分析。11份样品的水分含量为8.29%～22.81%,粗脂肪含量为7.51%～21.83%,粗蛋白含量为38.65%～45.53%,氨基态氮含量为306.65%～1876.55%,灰分含量为3.92%～7.66%。色度测定结果明岩村的YB7最暗,感官嗜好度较低。α-淀粉酶活力为27.72～1203.25U,地域之间差异显示为43.4倍,β-淀粉酶活力为8.61～17.36U,显示为2.02倍差异,中性蛋白酶活力为395.81～1999.11U,显示5倍以上的差异。菌落总数为8.9×105～3.3×107 cfu/g,霉菌和酵母菌为1.9×103～2.6×104 cfu/g,乳酸菌为3.1×104～8.9×106 cfu/g,不同地域之间显示显著差异(p<0.05)。可见,不同区域传统酱坯的品质存在很大差异,传统大酱产业化生产中建立酱坯品质标准时不可待。
