FOOD TECHNOLOGY

Detailed explanation-1: -Oxygen gas causes rancidity in food products is also called oxidative rancidity. Rancidity refers to the spoilage of food in such a way that it becomes undesirable (and usually unsafe) for consumption.

Detailed explanation-2: -It is well known that unsaturated fatty acids and oxygen are the components that react during the lipid oxidation process.

Detailed explanation-3: -Oxygen is the primary reactant in lipid oxidation reactions that cause rancidity in foods.

Detailed explanation-4: -Oxidation, a chain reaction that occurs in the presence of oxygen, is responsible for the deterioration in the quality of food products, including off-flavors and off-odors. It is affected by processing, packaging and storing methods, as well as product ingredients.

Detailed explanation-5: -Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction). Phenols and the enzyme phenolase are found in the cells of the apple, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes a reaction.
