Proper storage helps prevent rancidity of food, particularly oil and oil-containing products. Keeping oil in tightly capped bottles away from exposure to air, direct heat and sunlight aids in controlling the onset of rancidity.Know More
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.Learn more in Food Spoilage
According to HowStuffWorks, food preservation slows down the activity of disease-causing bacteria or kills bacteria in food altogether. Preserving food keeps it from spoiling too quickly, allowing it to last for weeks or even months longer than it does normally.Full Answer >
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.Full Answer >
Honey, white rice, sugar, pure vanilla extract and hard liquor are all types of food that never spoil, as long as they are kept sealed. If these foods are opened or unsealed, they still spoil over time.Full Answer >
Food spoilage is caused by bacteria, yeasts, fungi, the food's own enzymes, insects, temperature fluctuation and oxidation. When eaten, food that is spoiled by bacteria or other microbes presents a disease hazard to humans.Full Answer >
