Four Methods of Food Preservation
Food can go bad quickly. Hence, preservation methods should be used. Preserving food can help you maintain a healthy food supply. Furthermore, it can protect you from several food-borne diseases. Here are some of the methods of preserving food that you ought to know.
Canning is an Option
In order to survive, bacteria and yeast need adequate oxygen. Oxygen enables these organisms to grow and develop. Nevertheless, brine is another element that needs to be used in canning. This is because there are organisms that can survive in canned places with no oxygen at all. This technique is the most costly in comparison to other methods. It is becoming popular with time, mainly due to industrial growth. Canned foods can work well when you go camping. They are also a good option when natural disasters happen.
For food to go bad, there are specific temperatures that favor this. These agents are especially active anywhere from forty to a hundred and ten degrees. It is harder for food to go bad when stored in temperatures below this range. Their metabolic rate is decreased as well as their reproduction. It is essential to know that not all bacteria and yeast die when you freeze food. For places where temperatures are low, this is a cheap method. You can use it when camping in the mountains. You can also buy a freezer for home use. Using this technique, you will easily be able to carry food you have prepared already for the outdoors. Additionally, this technique can also work well for milk preservation.
Remove Water from the Food
This is also another method you can use for food preservation. It works by draining off moisture from the food. Microorganisms need moisture for survival. This technique needs an agent of evaporation. The common techniques are sun drying or use of electricity. Nevertheless, sun drying has a particular benefit. It can help to kill some of the agents of spoilage. You can use this method in the wilderness. It is also a convenient preservation method to use while camping. Use this method to preserve fruits or vegetables.
This technique is especially for liquids. You can use the technique to preserve milk in large amounts. Several wine producing companies use it to maintain the taste of the wine. You can use this method to kill germs. You are supposed to subject the liquid food to more than seventy degrees for at least ten seconds. After heating immediately, cool the milk or wine to ten degrees.
This is an essential step since it stops the growth of any remaining microorganisms. After all this, you can store the liquid in a sterilized container. You can use while traveling a long distance.
