酸奶中双乙酰含量的测定方法初探

Discussion on the determination of diacetyl in yogurt

根据酸奶中的成分的复杂性及双乙酰质量浓度的特殊性,研究了以鲜奶为溶剂制作双乙酰标准曲线和紫外分光光度法测定酸奶中双乙酰质量浓度的测定方法。该方法重现性好,测量误差小。

according to the yogurt＇s complex ingredient and the diacetyl＇s particular content, this article researches the determination of diacetyl in yogurt with ultraviolet spectrophotometer. In this technique, we adopt the dairy instead of water to inake the diacetyl＇s calibration curve. The result has good reproductivity and litde measurement error.
