Shelled eggs

Putting shelled eggs in the freezer is not a good idea to extend their shelf life. Because the white inside will expand when frozen, causing the outer shell to crack. At this time, eggs are easy to be attacked by bacteria, quickly spoil and cause bad odors in the freezer.

If you want to freeze the eggs, remove the whites and yolks from the shells and beat until smooth and store in an airtight container.

Fried foods

Therefore, for fried foods such as french fries, fried chicken, potatoes… should not be frozen. Putting them in the freezer will make the fried dough soft, mushy and watery.

Potatoes

Potatoes should not be frozen as they have a high amount of water. So, if you put them in the freezer, the water in the potatoes will form ice crystals that lose their nutritional value. They will be mushy, friable and watery. You should leave them out of the bag and just leave them on the counter or the floor.

Some fruits and vegetables
