That's fine. First, these explanations are confusing, which makes people feel that their milk powder is more responsible. Second, it is purely graffiti. According to scientific experiments, boiling water for three minutes is the best time. After three minutes, the nitrate content will increase greatly, which will lead to cancer. Normal milk powder is best to use ordinary boiled water, that is, warm boiled water, and then wash it when it is cooled to 70-80 degrees to avoid nutrient loss. So, don't listen to these words without scientific basis, and never let the water boil for five minutes! I wish you happiness!
