There are various food preservation methods, including freezing, canning, and drying, that can be done at home to save money and avoid exposure to chemicals. It’s important to research and understand the methods to ensure safety. Freezing is the simplest method, while canning and drying require more knowledge and caution.
There are several food preservation methods that can keep perishables packaged and safe for later consumption. Commercial food preservation techniques typically involve adding preservatives or other additives to food to prevent bacterial growth; packaged foods purchased at the grocery store are typically stored for freshness this way. Many people want to grow and store their own food for various reasons, however, such as saving money or avoiding exposure to pesticides or chemical additives. There are several food preservation methods that can be undertaken at home, such as canning, freezing or drying different types of foods. Some of these are easier than others, and it’s important to understand methods to ensure that food is safe to eat.
Freezing is one of the simplest means of preserving food. Many different types of foods can be frozen, from fresh vegetables to prepared casseroles, soups or sauces. Some vegetables need to be cut and blanched first, which involves boiling them for several minutes, then dunking them in cold water, to make sure they hold up in the freezer. Others can simply be harvested and frozen. The key is to freeze them when freshly picked and reduce exposure to air as much as possible. Some people use a vacuum sealer to achieve this.
Another of the most common methods of preserving food is canning. Works well with many different types of fruits and vegetables as well as pickled foods. Water bath canning and pressure canning are two different methods that ensure the jars are heated to a temperature high enough to kill bacteria; if not done correctly, canned foods can be extraordinarily unsafe. Making jam or preserves with fresh fruit is another slightly simpler food preservation method. Regardless, be sure to research before canning anything.
Drying or smoking foods are some of the more traditional ways of preserving food. Dry foods are not cooked, but moisture is removed to prevent bacterial growth. Today, many people simply use a dehydrator to dry foods quickly and easily, although it’s also possible to simply use the oven. With practice and awareness, many people find that these different food preservation methods allow them to enjoy wholesome, fresh foods year-round that are free from preservatives or other additives.
