In recent years, it has been often reported that non-nominal ingredients are found in milks from minor dairy species. Adulteration detection in milks from minor dairy species provides important technical support for market surveillance. DNA-based detection is a common and effective approach for food authentication, and also has advantages in milk adulteration detection. In order to provide a reference for the quality control of minor species milks, this article reviews the general aspects of minor species milks and the application of common DNA-based qualitative and quantitative techniques in adulteration detection in minor species milks in term of target gene selection, and their principles, sensitivities, application scenarios, advantages and limitations.
