If milk or yogurt has reached its shelf life, or a day or two has passed, but it has not changed color or taste, can it still be drunk? Perhaps everyone has such a struggle: drinking and worrying about health damage; Stop drinking. It's a pity to throw it away. Can I drink or not? First, expert guidance: How to judge whether milk has expired? First of all, judging visually: normal milk is milky white liquid, while expired and deteriorated milk will appear yellow and black, which may condense into tofu blocks or paste; Secondly, judging from the sense of smell, normal milk has fresh milk flavor, while expired and deteriorated milk will have sour, smelly and other smells. In the above situation, no matter whether the milk has passed the shelf life or not, you can't drink it any more. Maybe some friends have encountered the situation that milk goes bad before its shelf life. Don't be surprised at this time, because milk will be sterilized and sealed before packaging. If the packaging is not well sealed, bacteria in the air will enter the bottle, which will naturally deteriorate the milk through reaction. Second, can I drink milk that has reached the shelf life but has not deteriorated? For this question that everyone is extremely entangled in, the expert replied: "First of all, through sensory judgment. If there is no problem with sensory judgment, milk can still be drunk. " Why can I still drink when the shelf life is up? Experts further explained: "Generally, milk sold in the market has left consumers with a back road in the formulation of shelf life. If you buy a bottle of milk with a shelf life of 7 days, its actual shelf life may be 10 days, and it is impossible for milk to really go bad suddenly on the shelf life day. Therefore, if the milk has reached the shelf life, but it has not deteriorated from various senses, then the milk can still be safely drunk. If four or five days have passed, although it has not deteriorated, there is not much nutritional value left. At this time, it is best not to drink. " In addition, experts also specifically mentioned that if it is milk for children under 2 years old, don't give it to children even if it is not bad by the shelf life. Because there are more or less bacteria in milk, these bacteria may not pose any threat to adults with strong immunity, but children's intestines and stomach are still weak and their immunity is low. In order not to cause unnecessary health damage, it is best to give children milk that is still within the shelf life. 3. How can spoiled milk turn waste into treasure?
