香菇菌汤熬制工艺参数的优化研究

以香菇和猪骨为主要原料，研究香菇菌汤熬制的主要工艺参数。以菌汤中固形物溶出率和蛋白质溶出率为考察指标，通过单因素和正交试验分析和讨论，确定香菇菌汤最佳熬制工艺参数。结果表明：熬制温度为120℃、熬制时间为30min、料液比为1:70(g/g)、香菇粉粒度为60 目，在此工艺条件下，固形物溶出率和蛋白质溶出率分别达到44.55% 和40.56%。

Optimization of Processing Conditions of Shiitake Soup

Shiitake soup was made from shiitake mushrooms and porcine bone by cooking in boiling water. The processing procedure of shiitake soup was optimized by investigating the effects of cooking temperature, length of cooking time, solid-toliquid ratio and particle size of porcine bone powder on the dissolution ratios of solids and proteins using single factor and orthogonal array design methods. The optimum processing conditions were obtained as follows: cooking temperature 120 ℃ length of cooking time 30 min, solid-to-liquid ratio 1:70, and particle size of porcine bone powder less than 60 mesh. Under such conditions, the dissolution ratios of solids and proteins was 44.55% and 40.56% respectively.
