摘要: 以冷榨豆饼为原料,在小型单螺干挤压机上,研究了温度和水分对组织蛋白产品成型和褐变的影响,并探讨了成型与褐变的机理。研究表明:在一定水分条件下,只有达到一定温度,产品才能成型,即产品为完整管状,这是组织化水平高的表现。过高温度导致产品颜色褐变、表面均匀度下降和赖氨酸损失剧增,表明美拉德反应程度高。入料水分增加,成型所需温度也增加。190℃、20:13料水比条件下,产品成型、亮黄色、不褐变、表面平展、赖氨酸损失程度低,因此为最佳工艺条件。

Abstract: Effects of temperature and moisture on the finished-form and browning of texturized protein products extrudedwith a small single type extruder from crushed raw soybean were studied in this paper . It showed that the product extrudedcould not be in a finished form until processing temperature reached high enough when the products had the form of a wholehose, it reflectd a high level of texturization. But excessive high temperature made the product brown with less even appear-ance and with increasing loss of lysine , a result suggesting that high degree of Maillard browning reaction oscurred rapidly.The more the water content of mixed material, the higher the processing temperature was needed to make product befinished. The extrudates processed in the conditions of 190℃ and material:water=20:13 would be in well finished form withlight yellow and even appearance without browning and with only a little of lysine of the products lost, so the processingconditions of temperature and moisture were optimum.
