Can apples be put in the refrigerator

Apple is one of the most common fruits. It has the function of supplementing nutrition and can enhance the body's physical fitness. Among all fruits, the nutritional effect of apples is relatively balanced, and it has a long shelf life. Generally, after purchasing apples, you can put them in the refrigerator for a short time, but not too long. When putting them in the refrigerator, you can put them in a plastic bag so that they can be preserved for a longer time.

Can apples be stored in the refrigerator?

Can. But you can't keep it in there for a long time. If you put it in a plastic bag and put it in the refrigerator, it can be kept longer. Apples can stay fresh for 7 to 10 days if stored in a cool place.

1. Apples should be stored in a cold place to increase their sweetness. Because the sweetness of fructose and glucose increases at low temperatures, the sweetness will weaken above 50°C. Changes in temperature have no effect on sucrose.

2. Apples can be preserved for a long time in a low temperature and humidified environment. At home, you can wrap it in a plastic bag and store it in the refrigerator.

3. After peeling apples, the iron contained in the apples will quickly oxidize and turn brown. Therefore, they should be eaten immediately after peeling. If you want to prevent discoloration, you can evenly drain the apples with an appropriate amount of lemon juice or soak them in 0.3% to 0.6% salt water, and they will not change color.

How to keep apples fresh

Currently, apples are mostly kept fresh by using "paper bags" or "large plastic bags", and the effects are not ideal. Here is a new way to keep apples fresh:

1. Select apples that are not bruised, diseased or insect-free, and put them into the preservative solution (solution preparation method: add 10 grams of 2,4-d growth regulator and 50 grams of methyl thiophanate to 50 kilograms of water), immerse them and then take them out, especially the fruit stalks.

2. After soaking in the liquid medicine, carefully place the apples into a ventilation box or basket and let them air dry for 4-5 days (commonly known as sweating). The liquid medicine on the surface of the fruit will then dry up.

3. Carefully put the intact fruits into a single-layer plastic film fresh-keeping bag, tighten the bag mouth, and stack them in a box with ventilation holes, but do not crush the apples. This method can store apples for more than 7 months, with a good fruit rate of about 90%. Apples preserved in this way are not easy to lose water, the fruit is as fresh and sweet as before, and even the fruit stalks remain green. But you must be careful during the entire operation, handle it with care, and do not damage the fruit at all. The warehouse must also be cleaned first, and it is better to use earth walls, brick walls and tile houses. The best plastic bags are high-pressure polyethylene bags of 17×13 cm because of their good transparency and the good color of the fruits when packaged.
