Food Preservation Basics
Food preservation is basically about trying to keep the food as sterile as possible. Keeping them sterile involves preventing the growth bacteria that might spoil it. Most food naturally contains bacteria in them, this can help it spoil easily through the natural functions of the bacteria.
Food may contain enzymes that may break down and spoil it. Enzymes are special protein that acts as a catalyst for chemical reactions that happen in food, causing them to spoil. Such chemical reactions tend to discolor and lessen the quality of the food.
In order to prevent the actions done by bacteria in food, sterilization is used in order to kill the bacteria present in food. The process involves putting food under high temperatures in order to kill the bacteria, sterilizing it and then sealed to preserve its quality. High temperatures may also help break down the enzymes that may facilitate the rapid spoiling of food. Such enzymes are usually are fragile. High temperatures at around 150 degrees Fahrenheit or 66 degrees Celsius would destroy them and prevent the enzymes from doing their deed in spoiling food.
