Heating, cooling/freezing, packaging, drying, saccharifying, salting
Sugar preserves food by lowering the water activity (aw). If the aw is 85 or less, spoilage and pathogenic microorganisms can't grow. Microorganisms all need proper food, water, temperature and acidity to grow and adding sugar to appropriate levels can prevent bacterial growth.
Benzoic acid is added to prevent spoilage of cold drinks
Food is preserved by hypertonic solutions through osmosis, which is the movement of water from the food to the solution. This creates a high salt or sugar concentration in the solution, inhibiting the growth of microorganisms that cause food spoilage. The lack of water in the food also slows down enzymatic reactions that lead to spoilage.
BHA (butylated hydroxyanisole) is an antioxidant that is commonly used as a food additive to prevent rancidity and food spoilage. It is considered a synthetic antioxidant compound.
Louis Pasteur conducted his experiments on the spoilage of food in the 1860s. His groundbreaking work demonstrated that microorganisms cause food spoilage and spoilage can be prevented through processes such as pasteurization. This research significantly advanced the field of microbiology and food preservation.
Salt and sugar act as preservatives by drawing out moisture through osmosis, which inhibits the growth of bacteria, yeast, and mold that cause spoilage.

Adding sugar to food can help prevent spoilage by creating an environment with lower water activity, making it less hospitable for bacteria and other microorganisms to thrive. Sugar can also be used in canning and preserving processes to inhibit microbial growth and extend the shelf life of food products. Additionally, sugar can contribute to the formation of a protective barrier on the surface of certain foods, further inhibiting spoilage.
To prevent food spoilage, methods like refrigeration, vacuum sealing, drying, canning, using preservatives, oxygen absorbers, and proper packaging are commonly used.
The recommended meat storage temperature to ensure food safety and prevent spoilage is below 40F (4C).
Three steps a housewife can take to prevent food spoilage would be first refrigerate leftovers. Second heat leftovers thoroughly and third not leave utensils in with the food.
Most bacteria, which cause food spoilage, cannot tolerate the high salinity. The salt draws out moisture, causing them to die.

The main way that pasteurization methods prevent food spoilage is by removing the bacteria from the food. This is done by heating the food until it is hot enough to kill the bacteria and then holding it there long enough to make sure that all bacteria are killed.
