Therefore, if you buy back soy products, you should eat them as soon as possible. If you haven't finished eating, you should keep it fresh. Although refrigerators have spread to many families, putting things inside can't achieve the purpose of keeping them fresh. Look at the following scientific preservation methods. Tofu can be preserved by "salt water method": boiling salt water, cooling, soaking all tofu, and then putting it in the refrigerator. Dried tofu should be placed closest to the inner wall of the refrigerator. Soymilk can be stored overnight if it is directly refrigerated in the refrigerator; But if it is preserved by "sealing method", it can be preserved for one week. The specific method is: 1. Boil the soybean milk and quickly pour it into a sealable container (also blanch it with boiling water first). Don't pour it too full, leaving a gap of 1/5. 2, cover the lid, stay for more than ten seconds, and then screw the lid to the tightest. 3. After cooling to room temperature, put it in the refrigerator. Finally, don't forget to put garlic and vinegar in the cold bean products in summer, because these two seasonings have bactericidal effect. It's best not to leave any cold salad. If it is leftover, heat it thoroughly when you eat it next time. For example, you can add some fresh vegetables such as peppers and celery and fry them together.
