Answers
Spoilage is the process in which food deteriorates to the point in which it is not edible to humans or its quality of edibility becomes reduced. Various external forces are responsible for the spoilage of food. Food that is capable of spoiling is referred to as perishable food.
Harvested foods decompose from the moment they are harvested due to attacks from enzymes, oxidation and microorganisms. These include bacteria, mold, yeast, moisture, temperature and chemical reaction.
Bacteria
Bacteria can be responsible for the spoilage of food. When bacteria breaks down the food, acids and other waste products are created in the process.[1] While the bacteria itself may or may not be harmful, the waste products may be unpleasant to taste or may even be harmful to one's health.[2]
Useful Bacteria:
Vinegar Bacteria: Acetobacter sp.
lactic acid bacteria: lactobacillus sp.
Yeasts
Yeasts can be responsible for the decomposition of food with a high sugar content. The same effect is useful in the production of various types of food and beverages, such as bread, yogurt, cider, and alcoholic beverages
