How to freeze food at home?
The best frozen food is food with high amounts of fat-soluble nutrients: vitamin A, carotenoids, and vitamin E. These nutrients are stable during food processing and blanching and freezing. You can freeze food high in vitamins B and C, however, as these vitamins are water-soluble, they are usually dissolved in water, so it’s best to eat them fresh.
All you need to know about freezing fruits and vegetables is available at the National Center for Home Food Preservation website. You will find detailed information about blanching, food containers, packaging and labeling, food that do not freeze well, and more.
The most important thing to learn is how to store frozen food properly, because although you can freeze perishable food to preserve their nutritional value and flavor, the food does not stay fresh forever. When you store it properly, the food can remain fresh for no more than six months.
How can you choose the right frozen produce?
The best is to follow the same rules you apply when shopping for fresh produce.
Read the label. Although most frozen produce are salt- and sugar-free, it’s still important to read the labels. Frozen fruits and vegetables can be packed with unnecessary added sugars and sodium, so check a package’s Nutrition Facts Panel and read the ingredient lists for unsuspecting ingredients.
“Fresh frozen” and “frozen fresh” are terms you should look for on the package. It is used for foods that are quickly frozen while fresh, where blanching is allowed. “Quickly frozen” usually means that the food is frozen via a system such as blast-freezing.
Look for organic. Another important thing when choosing frozen food is to look for organic food, which is pesticide-free. Most supermarkets carry a variety of frozen produce, but the best is to choose organic over conventional.
The truth is that frozen fruits are convenient; the food is pre-washed and often pre-chopped, and cheaper. Most of all, they are no different in nutritional value to their fresh counterparts.
You can also be very creative with frozen produce! Besides smoothies, you can enjoy them in desserts and cakes.
