The method for testing the authenticity of Youzi goat milk powder is as follows:

1. Check whether the package is intact, whether the seal is regular and whether the mark is clear.

2. Distinguish colors. Real milk powder is natural milky yellow, and inferior milk powder is white or bleached white.

3. Try to feel that the real milk powder is delicate in texture and makes a "squeaky" sound; Inferior milk powder particles are coarse and make a "rustling" sound.

4. Smell the taste, real milk powder has the unique milk flavor of milk; Inferior milk powder has little frankincense or even no milk smell.
