Method for judging adulteration of goat milk formula milk powder

Abstract

The invention aims to provide a convenient method for detecting adulteration of goat milk formula milk powder. The method can accurately judge whether adulteration milk powder of milk powder is addedinto the goat milk formula milk powder or not, or the goat milk formula milk powder does not contain goat milk and is pretended by milk. The method comprises the following steps of by adopting a gas chromatography method, establishing a fingerprint spectrum library of aroma compounds in unadulterated goat milk formula milk powder and a fingerprint spectrum library of aroma compounds in an unadulterated cow milk formula milk powder, screening out characteristic aroma compounds in the unadulterated goat milk and cow milk formula milk powder, and determining the index aroma compound for identifying the goat milk formula milk powder by utilizing least square discriminant analysis. The detected aroma compounds in a sample to be detected are compared with index aroma compounds in the unadulterated goat milk and cow milk formula milk powder, whether the sample to be detected contains the goat milk or not can be determined, whether the sample to be detected is adulterated or not can be determined, and judgment can be carried out more visually and quickly by combining a principal component analysis method.

Description

technical field [0001] The invention belongs to the field of food science and technology, and particularly relates to a method for identifying whether goat milk formula milk powder is adulterated. Background technique [0002] Infants and young children are a special group, and breast milk is the most ideal food for infants and young children. Breast milk not only provides a source of nutrition, but also contains biological components that promote the normal growth and development of infants. However, due to various reasons, the breastfeeding rate of infants and young children is decreasing year by year. In the case of no breast milk or insufficient breast milk, infant formula milk powder has become the most important daily food source for infants and young children as a substitute for breast milk. [0003] The research and production of infant formula milk powder in my country started relatively late, and currently infant formula milk powder is mainly based on cow's milk. ...

AI Technical Summary

Problems solved by technology

However, the yield of goat milk is low, the cost of raw materials is high, and it is affected by seasonal changes. Therefore, manufacturers are driven by economic interests to mix lower-priced, higher-yield cow’s milk powder into goat milk formula milk powder. appear frequently

This kind of adulteration not only damages the economic interests of consumers, but also poses a threat to the health of consumers with milk allergies.
