摘要
Abstract
In order to determine the contents cow' s milk in goat milk,a rapid detection was established.At first,the non-linear chemical fingerprints of the standard samples with different cow' s milk contents were determined,and a correction model was fitted for the linear relationship between the inductive time of fingerprint and the cow's milk content.And then,the cow's milk contents in the samples were calculated by using the correction model and the induction time.Last,according to the cow' s milk content,the authenticity and quality of goat milk was accurately identified and quantitatively evaluated.The results of 5 verification samples by the method showed that the relative standard deviations was ≤2.1％,and the recovery rates are 97.3 ～102％.The method had good reproducibility and accuracy.It is a practical,accurate and rapid detection of adulteration of goat' s milk and quantitative evaluating the quality of the dairy.In addition,the method can also be a reference on determine other mixed system.关键词
