"Milk" must hide
The study found that milk is acidified and deteriorated when it is directly exposed to sunlight for 4 minutes. In the light of the supermarket freezer, its "best preservation period" is only about 4 hours!
Expert Weapons: When visiting the supermarket to buy milk, it is best to pick the last row of shelves; milk is poured in the cup, it is best to drink within 4 minutes; buy milk, the best carton packaging, home after the most Let it be in a refrigerator freezer at 2°C~6°C.
"Black tea" and "green tea" are divided into
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.
Fruits and vegetables placed on the same side as metamorphosed "infection"
Two kinds of release, metamorphism and easy "infection." Not only do people get infectious diseases, but the spoilage between fruits and vegetables can also be “infected.”
Experts Weapons: "Filling" green leafy vegetables are best kept in the refrigerator and eat as soon as possible. Radishes, carrots, cabbage, potatoes, onions, apples, pears, etc., all belong to storage-resistant food and are suitable for putting on the balcony. Potatoes and other root vegetables, the smaller the size, the higher the content of vitamin C. Paper bags can be stored to prevent excessive light and oxygen from damaging the dimension C.
"Edible oil" can't be next to the stove
For convenience, many housewives often place cooking oil near the stove. As everyone knows, the high temperature there will accelerate the oxidation of the oil and make it more susceptible to spoilage.
Experts Weapons: The best storage temperature for cooking oil is 10°C~25°C. Store it away from heat sources, such as gas stoves, rice cookers, and microwave ovens. After the bottled oil is bought at home, it can be bottled and bottled. , to avoid the constant opening and closing of the bottle cap, oil contact with the air and oxidation to produce hazel taste. It is best to use dark colored glass bottles rather than transparent oil storage; hot salt can be added to edible oils in a ratio of 40:1 to absorb moisture and keep the oils clear and odoriferous; it can also be used in cooking oils. Add 1 to 2 vitamin E to enhance the antioxidant capacity of the oil.
"seasoning" is best to use tin foil package
Many studies have confirmed that spices such as pepper, fennel and cinnamon have anti-cancer and anti-cold effects. However, these health effects will not be maintained. For example, capsaicin in pepper powder can only last about 9 months!
Expert Weapons: The garlic is empty, the green onions dry, and the ginger grows green, which has always been a problem in the kitchen. The best solution is to cut the tin foil to the right size before storage and wrap tightly the unwashed green onion, garlic, and garlic so that it can at least extend its shelf life to more than one month. Onion can be cut first, cut green onion, with a fresh box directly into the freezer in the refrigerator; Garlic contained in garlic has a bactericidal function, is not easy to spoil, so it is recommended to store the entire head.
Grains must also be protected from light
Studies have found that cereals contain a lot of vitamin B2, and the light damages their nutrition.
Expert Weapons: Do not buy too much rice at a time, ready to use 15 to 30 days; brown rice must not be able to buy bulk, although it is nutritious, but the shelf life is very short, usually only six months. In particular, vitamin A and vitamin C, which are left in the air for about 3 months, are completely oxidized and their health effects are lost. When stored, pasta, rice, and grains are best placed in opaque containers or rice bags. Because brown rice, sesame seeds, and nuts contain oils and fats, they tend to deteriorate at room temperature and have a hazel taste, so they need to be refrigerated or even frozen.
