Heat alone is not enough to preserve food unless it is used to dehydrate. Heat kills bacteria and pests and their eggs that may be in food and that assists in the preservation of food. In addition to heat food needs to be cured, smoked, canned, fermented, or frozen to preserve it for an extended period of time.

Why heat is used to preseve food?
Heat of itself does not spoil food. What spoil the food is the growth of bacteria in the food.At low temperatures (in a fridge) these bacteria only grow slowly but when the food warms up to room temperature the bacteria grow faster and the food will spoil. The reason for this is that for every 10oC rise in temperature the rate of chemical reactions (ie the metabolic rate of the bacteria) doubles. Obviously above a certain temperature (boiling point) the heat is so much that the bacteria are killed off.
Can heating be used in the preservation of food and media?
Heating to over 160F will kill all major food spoilage bacteria. This is the process used in both pasteurization and food canning to preserve foods. If you do not heat to 160F enough bacteria will survive to cause the food to spoil in the can and cause food poisoning, this is a common issue with home canned food.
