目的鉴别豆浆中是否有豆浆伴侣存在。方法制备含有不同浓度豆浆伴侣的豆浆,加入硫酸镁,计算沉淀凝固物的含量。结果硫酸镁溶液不能使豆浆伴侣沉淀,但能使大豆蛋白凝固,进而能快速鉴别豆浆中是否含有豆浆伴侣。结论此方法简便、可行。 Purpose To identify whether there is a soybean milk mate presence. Methods Soy milk containing different concentrations of milk mate was prepared, and magnesium sulfate was added to calculate the content of precipitated coagulation. As a result, the magnesium sulfate solution can not precipitate the soy milk partner, but enables the soy protein to coagulate, thereby quickly identifying whether the soy milk contains the soy milk partner. Conclusion This method is simple and feasible.
