核桃仁中总糖的测定与评价

Determination and Evaluation of Total Sugar in Walnut Kernel

以核桃仁作为实验原料,通过3,5-二硝基水杨酸法准确测定核桃仁中的总糖含量,在选取540 nm作为合适的测定波长后进行相关的测定。通过实施实验及实验数据的表征得知,实验误差以及可行性均处于一个较好的水平,能够满足相关测定要求。

In this experiment,walnut kernels were used as the experimental raw materials,and the total sugar content in walnut kernels was accurately determined by the 3,5-dinitrosalicylic acid method.After selecting 540 nm as the appropriate measuring wavelength,the relevant determination was carried out.The implementation of the experiment and the characterization of the experimental data show that the experimental error and feasibility are at a good level,which can meet the relevant determination requirements,and provide a reference for the determination of sugar in walnut kernels.
