Talking about supermarket purchase

Eat, wear, live and travel. Eat? Always put it in the first place. In daily life, storable things such as rice, noodles and oil are generally bought and stored at home. In addition, many people like to buy a lot of vegetables at one time and stuff them all in the refrigerator, thinking that this will save trouble and reduce the number of trips.

However, the refrigerator is not everything. Vegetables in the refrigerator can't be guaranteed to be foolproof. Some vegetables go bad faster. Different vegetables not only have different storage time, but also have different storage methods. When you go to the supermarket to buy goods, these five vegetables are delicious and storable, and the key prices are also very cheap. You can't use one hundred dollars. You can buy enough for a family to eat for half a month. Let's see what vegetables are on the list.

1, potato

Potatoes are the favorite of many people. Whether it is fried, steamed or fried, it is very delicious. Rich dietary fiber is also very helpful to human health. Potatoes are cheap, 2 yuan a catty, and they are also very resistant to storage. They don't need to be kept in the refrigerator. Just put it in a cardboard box and put it in a dry and ventilated place. Generally, the preserved ones can be kept for about 45 days. But potatoes have a disadvantage that they germinate easily. We can put apples and apples.

2. onions (surname)

Compared with other vegetables, onions are cheap and affordable, 50 cents a catty, and special? Radiation resistance? It can be stored in a cool and ventilated place for 3 months, but the onion is afraid? Bored? It's best not to put it in a closed plastic bag, but if the chopped onions can't be eaten in time, they can be stored in the refrigerator for three to five days with plastic wrap, but it's best to cut as much as you eat, because the onions are delicious and easy to cross with other foods in the refrigerator.

Step 3: beans

As one of the most popular vegetables in 3 yuan, the price is not expensive. Fresh beans will get old in a week or so, but there are other storage methods, such as blanching, drying, putting them in fresh-keeping bags and finally freezing them in the refrigerator. You can eat it at any time and take it at any time, and the taste will not change much. Or simply dry it into dried bean curd, which has better flavor.

4. tomatoes

Tomatoes are the most common vegetables, and 5 yuan can buy a big bag with cheap money. However, many people have such a misunderstanding that tomatoes will only go bad slowly in the refrigerator. However, this will not only shorten the shelf life of tomatoes, but also make the taste worse. The low temperature in the refrigerator will destroy the cell wall of tomatoes, thus accelerating the decay time. The correct way is to put the tomatoes in a fresh-keeping bag, exhaust the air and put them in a ventilated and cool place, so that the tomatoes will be as fresh as they just bought.
