Less Spoilage, more usage. Food preservation is a process by which food is kept fit and healthy for human consumption. It is no doubt that daily, food goes to waste as a result of food spoilage. This may occur as a result of excessive buying as well as inappropriate storing of food.

Food preservation has become necessary as consumers are expected to finish certain produce depending if they are in or out of season. Preservation of food allows for variety, cuts down on food waste, and expands the supply of food at any given point.
