1. Milk: Avoiding light storage Light not only kills but also “kills†nutrients in the milk. The study found that milk is acidified and deteriorated when it is directly exposed to sunlight for 4 minutes; under the light of supermarket refrigerated cabinets, its “optimal preservation period†is only about 4 hours. The vitamin B2 in milk is very sensitive to light and can be rapidly lost in the light. The light will also oxidize the lipids in the milk, causing other nutrients such as vitamins A, D, B6, B12 to be slowly damaged. Among them, milk in glass jars or plastic cans is the most vulnerable. Expert Weapons: When shopping in the supermarket to buy milk, it is best to pick the last row of shelves; milk is poured into the cup, it is best to drink within 4 minutes; when buying milk, select the carton packaging, immediately after returning home 2 °C -6 °C refrigerator freezer. 2. Tea: Green tea is stored in refrigerator, and black tea is placed at normal temperature The health benefits of green tea have been proven to help prevent heart disease, cancer, Alzheimer's disease, etc., mainly because of the catechins contained therein. However, the study found that when the green tea was left at room temperature for 6 months, the catechin content was reduced by 32%. Experts Weapon: Green tea that can be drunk can be stored at about 5°C in the refrigerator freezer; unopened tea leaves should be placed in the freezer if you want to keep it for more than one year. To prevent tea from becoming a "deodorant" in the refrigerator, it is best to seal it with a tin can before putting it into the refrigerator. Oolong tea, black tea, and jasmine tea do not need to be stored in the refrigerator, and can be stored for a long time as long as they are placed in a container that is dry, sealed, protected from light, and protected from odors.
