为优化发酵纳豆酱的后熟工艺条件, 以发酵成熟的纳豆为原料, 以纳豆激酶活性为指标, 就纳豆酱后熟过程中的前期水浴温度、 时间、 盐水质量分数、 盐水添加量以及后续低温后熟时间对纳豆激酶的影响进行了研究, 并采用响应面法优化了工艺参数.结果表明: 发酵纳豆酱最适后熟工艺条件为添加质量分数3%的盐水0.60 mL/g, 58℃水浴23 h后, 在4~10℃后熟5 d, 此时纳豆酱的纳豆激酶活力达到768 U/g, 同时氨基态氮的质量分数达到0.77%, 口感绵滑细腻, 有明显的酱香味, 感官评价良好.
為優化髮酵納豆醬的後熟工藝條件, 以髮酵成熟的納豆為原料, 以納豆激酶活性為指標, 就納豆醬後熟過程中的前期水浴溫度、 時間、 鹽水質量分數、 鹽水添加量以及後續低溫後熟時間對納豆激酶的影響進行瞭研究, 併採用響應麵法優化瞭工藝參數.結果錶明: 髮酵納豆醬最適後熟工藝條件為添加質量分數3%的鹽水0.60 mL/g, 58℃水浴23 h後, 在4~10℃後熟5 d, 此時納豆醬的納豆激酶活力達到768 U/g, 同時氨基態氮的質量分數達到0.77%, 口感綿滑細膩, 有明顯的醬香味, 感官評價良好.

In order to optimize the postripeness technology of natto sauce, the effects on natto kinase ac-tivity of pretreatment temperature, time, salinity, volume of saline and storage period at low temperature were tested with ripe natto as main material and natto kinase activity as index.The technological parame-ters were optimized by the method of response surface.The optimal conditions for postripeness of natto sacuce were determined, such as salt concentration was 3%, volume of saline was 0.60 mL/g, 58℃for 23 h, and then 5 d under 4-10℃.Natto kinase activity of natto sauce reached 768 U/g, and the con-tent of amino nitrogen reached 0.77%.Natto sauce of good sensory evaluation was smooth with delicate taste and obvious sauce flavor.
