Check the package
Authentic Hong Kong version of Wyeth Qifu milk powder, its packaging is intact, the seal is regular, and the product information, production date and shelf life are clearly printed. If the packaging is not tightly sealed or the trademark is vague, it may be a fake and shoddy product.
Handfeel test
Gently rubbing the milk powder packaging bag, the authentic Wyeth Qifu has a delicate texture and makes a crisp "squeak" sound. If the sound rustles, it may be inferior.
Observe color
Authentic Hong Kong version of Wyeth Qifu milk powder is a natural milky yellow, neither too white nor too bright.
Smell the taste
Open the package, genuine milk powder emits natural frankincense. If the frankincense is small or tasteless, you need to be vigilant.
Taste it
Take some milk powder and put it in your mouth. The real product tastes delicate and sticky, and it is easy to stick to teeth and maxilla. Inferior milk powder dissolves quickly and is too sweet.
Dissolution experiment
When brewing with cold boiled water, the genuine product needs to be stirred to milky white turbid liquid. If the genuine product is washed with hot water, it will form suspended matter and float. If it dissolves quickly without precipitation, it may be fake and shoddy.
