Abstract:To identify and test the quality of commercially available goat milk powder (pure and formulated) from different regions (Shaanxi, domestic non-Shaanxi regions and foreign regions), electronic nose and electronic tongue technology were used to analyze and discriminate 35 such samples from these regions with different formulations. The analysis results showed that electronic nose was able to achieve effective differentiation between pure and formulated goat milk powder, as well as between pure goat milk powder from domestic and foreign regions. Additionally, the electronic tongue technology can achieve effective differentiation between pure and formulated goat milk powder, and between pure goat milk powder from Shaanxi and domestic non-Shaanxi regions. Therefore, electronic nose and electronic tongue can be used to analyze goat milk powder from different origins and different formulations, to identify its origin and evaluate the quality. It is believed that this study provides a theoretical basis for a rapid and accurate evaluation of the quality of goat milk powder and its standardized production.
