【摘要】 研究在不同温度、不同蒸汽添加量以及不同的压力环直径条件下,挤压膨化对大豆中脲酶活性的影响。结果表明:膨化温度在120℃时,大豆中的脲酶活性被严重破坏,其值为0.35 U,较原料中的5.36 U有了大幅度的降低,此时大豆中的脲酶活性达到国家标准规定值(0.4 U以下)。更多还原

【Abstract】 The influence of extrusion on activity of soybean urease was studied under different temperatures, different steam amounts and different pressure ring diameters. The results indicated that under a temperature of 120℃, the activity of soybean urease was seriously destroyed and its value was 0.35 U, which was greatly lowered in comparison with 5.36 U of raw material and reached the value specified in state standard (less than 0.4 U).更多还原
