Refrigerator plays an essential role in our daily life as it plays a role in extending the shelf life of various ingredients and foods as long as possible. In particular, freezing food in the freezer has the advantage of being able to keep it longer than refrigeration. However, in the case of certain foods, if they are frozen, the taste, shape, and texture may change, and it may even cause the growth of bacteria or bacteria, increasing the risk of various diseases. So today, let’s look at the types of foods that are not good to freeze in the freezer one by one.
Foods not good for freezing
The first food that is not good for freezing is potatoes, which are often used as ingredients for various dishes because of their bland taste. Freezing raw, uncooked potatoes not only loses their original texture, but also changes color. Also, frozen potatoes become crispy when cooked and lose their taste, so it is recommended not to freeze them as much as possible.
2. Juicy Vegetables
Even vegetables that contain a lot of moisture, such as cucumbers, lettuce, and celery, are not recommended to be frozen. When freezing, it freezes easily with a lot of water, which causes cell wall rupture and tissue damage. As the shape is transformed by this action, the original texture, taste, aroma, and color all change. Therefore, in the case of vegetables with a lot of moisture, it is definitely a good idea to keep them refrigerated.
Eggs, which are called complete foods because of their rich protein, essential amino acids, and minerals, are also in the group of foods that are not recommended to be frozen. It doesn’t matter if it’s a cooked egg, but in the case of a raw egg, when it is frozen, the inside expands and cracks occur on the surface of the egg. And when the egg is cracked, the bacteria or germs attached to the shell can penetrate. Therefore, if you want to freeze the eggs, it is recommended to break the shell and store them in a container in the freezer.
Cheese made by extracting casein from milk, coagulating and fermenting it, contains a lot of protein, fat, and vitamins, and is a dairy product widely used in cooking and baking. When cheese is frozen, it loses its original soft texture and is transformed into a crumbly form. Therefore, it is recommended not to freeze it as much as possible, and if it is necessary to freeze it, it is better to use it in a pre-cut state. Also, like cheese, sour cream and whipped cream, which are types of dairy products, are separated into milk fat and fat during the freezing process in the freezer and are transformed into a floating form, so it is best not to freeze them as much as possible.
Mayonnaise, characterized by its savory yet salty taste, is a sauce made with vegetable oil, egg yolk, vinegar, and a little salt and pepper. It has a manufacturing characteristic of mixing liquids that are not placed on each other, so when it is frozen, it separates into water and oil. Also, it is not recommended to freeze foods such as salad dressings, which are added to dishes such as salads, because they have similar manufacturing characteristics to mayonnaise.
6. Coffee Beans
There are cases in which coffee beans are frozen after purchasing a lot. Coffee beans also act as a deodorant that absorbs odors, because when stored in the freezer, they can absorb the smell of food inside and absorb the unique aroma and taste of coffee beans. Fresh roasted beans that have not yet been opened can be stored frozen for about a month, but once opened, they should not be refrigerated again.
