Question

Things to think about concerning food preservation:

Food rots because different kinds of bacteria eat the food before you do.
To prevent this from happening, you must either eliminate the bacteria or create an environment that slows their ability to grow or reproduce.
Radiation, changes in pH, the removal of oxygen, and hot temperatures are factors that can be used to kill the bacteria in a food product.
Cold temperatures, dehydration, and chemical preservatives are factors that can slow the rate at which bacteria reproduce.

Go to the internet and read or watch videos about how food is “canned” and explain which of the above factors are used to keep bacteria from eating canned food items. You do not need to cite your sources but you do need to write 3-4 sentences.

When food is canned, one of the factors used to prevent bacteria from eating the canned food is the removal of oxygen. In the canning process, the food is sealed in airtight containers, which eliminates the presence of oxygen. This lack of oxygen inhibits the growth of bacteria, as many bacteria require oxygen to survive and reproduce. Additionally, hot temperatures are also used in the canning process to kill any bacteria present in the food. The food is typically heated to a high temperature, known as the sterilization temperature, which effectively eliminates any harmful bacteria.
