1, for fresh potatoes that are not rotten and slightly germinated, the length of the bud is only about 0.2mm, and the surface is not rotten and deteriorated. You can peel them and completely peel off the cortex near the bud mouth.

2. Remove the sprouting part, and at the same time, pay attention to thoroughly dig around the bud eye, and dig deep at the place where the bud mouth is down 1cm, and there is no discoloration around the bud mouth.

3, but also to remove the purple and green positions, which is not enough, we have to fully soak in water for more than 30 minutes.

Preservation method of potatoes

The first method: put the potatoes in a black bag and keep them in a dark environment.

When buying potatoes, it's best to choose those that are muddy, dry, intact and germinated. Don't wash them when storing them. Put the potatoes directly in a black bag, tie the mouth tightly, and then put them in a cool and ventilated place. This method can keep the potatoes from sprouting and deteriorating for a long time.

Potatoes are afraid of sunlight, and tend to sprout or turn green when exposed to sunlight, so putting potatoes in a black bag will create a dark environment for potatoes, which will not be exposed to sunlight, and put them in a cool place to avoid high temperature environment.

The second method: put the potatoes in a carton and preserve them with baking soda.

Spread newspaper in a dry carton, sprinkle a little baking soda on the surface of the newspaper, put potatoes in the carton, then cover the carton and put it in a cool, ventilated and dark place.

The principle of carton and black bag is to create a dark environment for potatoes, but newspapers can absorb moisture and avoid rot, while baking soda can prevent potatoes from sprouting, so it can keep potatoes for a long time.

The third method: soak potatoes in salt water, and then store them in cartons.

This method needs to clean potatoes, but don't damage the skin of potatoes when cleaning, just wash away mud or dirt. Then put a proper amount of salt in a clean basin, add a proper amount of water, and the ratio of salt to water is 1: 15. After stirring evenly, put the potatoes into the salt water. Soak for five minutes. When the time is up, take out the potatoes and put them in a cool place until the surface of the potatoes is dry.

Finally, just put the potatoes in a cardboard box, so that the preserved potatoes will not germinate or go bad, and the potatoes are fresh at any time, and the salt water has a fresh-keeping effect.
