摘 要：为提高原料利用率及酱油风味，通过在酱油酿造的泡豆工序中增加黄豆焙炒工艺，以减少泡豆工序中黄豆水溶性蛋白质的流失。结果表明，黄豆焙炒的最佳温度为200
℃，在此条件下，黄豆中的蛋白质充分变性，降低了泡豆时黄豆蛋白质的溶解度，进而减少了黄豆水溶性蛋白质的流失。在制曲阶段，大曲蛋白酶活力≥ 2000U/g，天然油氨基酸≥ 1.0g/100mL，原料利用率达85%。

Abstract： With the development of science and technology， the key to fermentation of domestic soy sauce enterpris is to improve the utilization rate of raw materials and the flavor of soy sauce.This article mainly studies to increa the soybean roasting process in the bean soaking process to reduce the loss of water-soluble protein in the bean soaking process; the optimal temperature for soy bean roasting is 200°C， so that the protein in the soybean is fully denatured and the soybean protein in the bean soaking process is reduced.The solubility of the soybean， which reduces the loss of soybean water-soluble protein， makes the activity of Daqu protea ≥ 2000U/g， natural oil amino acid ≥1.0g/100mL， and then achieves the purpo of improving the utilization rate of raw materials to 85%.
