1, ethylene gas method: First of all, our first method is to take out the potatoes that need to be preserved. At the same time, we should also pay attention to whether there are scratches or damaged moldy places on the potato surface. If we find broken potatoes during the inspection, we can take them out and throw them away at once.

2. Air-blocking method: Let's take a look at the second method first. Let's prepare what we need in the future, that is, plastic wrap and black plastic bags needed in daily life. When we are ready, take out the potatoes first, spread the plastic wrap flat, put the potatoes in the plastic wrap one by one, and then wrap the potatoes in plastic wrap.

This kind of secondary protection can make potatoes keep one more layer. After packaging, we just need to put the potatoes in a ventilated and cool place, so that the preserved potatoes can be kept for 1.2 months.

3. Sprinkle some baking soda: On the top of the paper, take out a handful of baking soda. The third trick here is to sprinkle some baking soda. Baking soda is a natural desiccant when stored, and it is also a small expert in cleaning.

So when we keep potatoes, we can prepare some baking soda in the carton, put the baking soda away, then put the potatoes that need to be preserved on the baking soda, and finally block the carton to avoid sunlight.

Then our third measure is more suitable for a large number of potatoes that can't be eaten at home. This practice will not be moldy or green for a year. Is it simple?
