酵母体内海藻糖定量方法研究

Study of trehalose quantitative analysis of yeast extract

海藻糖是性质稳定的非还原性双糖,在食品工业中应用广泛。以实验室常用的方法,即应用硫酸蒽酮法、旋光法、薄层扫描法等3种不同方法对酵母体内海藻糖的定量测定进行研究。结果表明,旋光法在对酵母体内海藻糖的测定中效果最佳。

Trehalose is the nature of the stability of the non-reducing disaccharide,widely applied in food industries.In this paper,application of anthrone sulfuric acid method,polarimetry and thin layer chromatography scanning（TLCS） in yeast quantitative determination of trehalose were studied.The results showed that polarimetry method was the best mensuration of trehalose in yeast.
