木耳增重掺假判别方法研究
目的 建立木耳增重掺假的综合判定方法。方法 木耳掺假主要是采用掺入氯化镁、硫酸镁等镁盐增加重量谋取暴利, 因此, 可以通过检测木耳中镁的含量、分含量、吸水性等指标来推测木耳中是否添加了镁盐。结果 木耳中镁的本底值在2500 mg/kg以下, 木耳灰分、吸水性的本底值分别小于6%和大于6 mL/g。结论 通过考察木耳中镁含量、灰分值、吸水性的基底值, 以帮助判断木耳样品中是否被人为添加镁盐。该方法对判别木耳增重掺假是可信的方法。
Objective To establish a detection method for determining the artificial weight gain by adulteration in edible fungus. Methods The artificial adulteration of fungus for weight gain was mainly obtained by adding magnesium chloride, magnesium sulfate, magnesium and other weight increase methods. By detect-ing indicators of fungus in magnesium content, ash content, water absorption, etc. to speculate whether the fungus was added magnesium or not. Results The background value of magnesium in fungus was less than 2500 mg/kg, the bottom ash was less than 6% and the value of water absorption was greater than 6 mL/g, respectively. Conclusion This method is credible, by detecting the magnesium content, ash value, absorbent base value of the fungus, to determine whether the sample was artificially added magnesium.
