Full Answer

Water and microorganisms also cause some fatty foods to become rancid following hydrolytic rancidity and microbial rancidity, respectively. Keeping fatty food away from water and microbes is essential.

Another way to prevent or reduce the onset of rancidity is to use antioxidants. Some natural antioxidants used for food include ascorbic acid and tocopherol. However, the use of synthetic antioxidants, such as butylated hydroxyanisole and ethoxyquin, gives the food a longer shelf life.

  • Q:

    Why does food rot?

    A:

    When food is slaughtered or harvested, its animal or plant tissue begins to decay. Without these tissues, microorganisms, such as molds, yeasts and spoilage bacteria, eat away at foods and cause the spoiling process. Other causes of spoilage include piercing or bruising of fruits or vegetables, oxidation, pest infestation and adulteration through the addition of leftover ingredients to fresh food.
