Tips for keeping fruits and vegetables fresh

Vegetables and fruits have been picked, transported and bought home for a long time. Coupled with the high temperature weather, even if it is put into the refrigerator, the vegetables will be dehydrated and dried up within two days. In fact, in order to keep vegetables fresh, in addition to the appropriate refrigeration temperature, the most important thing is to isolate the air.

First put a handful of vegetables into the fresh-keeping bag, don't fill it too full, and leave a 1/3 position at the mouth of the bag!

Then prepare a basin of water and sink the fresh-keeping bag with vegetables into the water. Remember to leave the bag mouth outside, and don't let the water drown the bag mouth.

Then, with the help of water pressure, the air in the bag is squeezed out, the vegetables are pressed, gently rotated, and the air in the bag is completely emptied, and then the bag mouth is tied tightly. In this way, vegetables can be stored in the refrigerator for more than three days, and the leaves are still tender green when they are taken out.

Water absorption and retention method

Bought flowers can be put in vases and kept in water for many days. In fact, vegetables can also be kept fresh in this way.

This method is suitable for root vegetables such as asparagus, spinach, celery and Chinese cabbage. Just tie these vegetables into a bundle, put them in a bottle, and pour some water so that the roots of the vegetables can absorb water.

Vegetables so preserved can be stored for 1-2 weeks even if they are not put in the refrigerator, as long as the temperature is appropriate.

Of course, the temperature is high in summer In order to keep vegetables fresh, you can put them in a small water bottle and put them in the refrigerator. Vegetables can be eaten for a long time once ~

Towel preservation method

Just make fruits and vegetables more hydrated and help them lock in water. Therefore, wrapping vegetables and fruits with soft cotton bags or this towel can effectively reduce the transpiration of water and make food fresh.

After buying fresh vegetables, you can pick the leaves, wash them, chop them into small pieces, wrap them in towels, put them in a fresh-keeping box and put them in the refrigerator for refrigeration.

In this way, vegetables can be kept fresh for more than 4 days. If it is potato, carrot and other root vegetables, it can be preserved for a longer time, and it is not afraid of germination or deterioration.

Tissue preservation method

Ordinary paper towels, in addition to wiping hands and cleaning, are actually artifacts for food preservation.

Roll up fresh vegetable leaves with kitchen paper towels and put them in sealed fresh-keeping bags, so that the paper towels can absorb water, keep the leaves in a relatively stable humidity state, reduce the loss of water and keep them fresh effectively.

Besides vegetables, melons and fruits can also use this method. For example, if you want to keep cucumber tender, you'd better wrap a paper towel outside and wrap it with plastic wrap, so that the cucumber skin won't dry.

The fruit bought home can also be preserved in this way, and it doesn't have to be wrapped tightly with paper towels, just put a layer of paper towels at the bottom of the fresh-keeping box.

Tin foil preservation method

Large vegetables, such as celery, are inconvenient to keep in sealed boxes or bags. You can try baking tin foil.

Cut off the roots of celery, and then wrap the roots of celery with tin foil, so that celery can remain fresh, complete, crisp and refreshing whenever it is eaten.

This method is also suitable for whole Chinese cabbage, lettuce and other vegetables. The principle of tinfoil preservation is also to isolate the air. Thick tinfoil can be closely attached to the ingredients, and the preservation effect is better than that of ordinary plastic wrap!

seal pot

The best way to make vegetables and fruits easy to store and keep fresh for a long time is to wash and chop them up and put them in sealed boxes or cans.

Vegetables can be classified according to the weight used in each cooking, and the ingredients can be taken directly when needed, which saves a lot of time, and the refrigerator looks more hygienic and tidy, so there is no need to worry about the smell of ingredients.

If there is no special storage tank, use plastic bottles instead. Look! Chop up the onion and put it in the bottle as long as you want!

Cucumber can also be made in the same way. Remember to put paper towels for better preservation ~
