Option 2 : Oxygen

  • Oxygen gas causes rancidity in food products also called oxidative rancidity.
  • Rancidity refers to the spoilage of food in such a way that it becomes undesirable (and usually unsafe) for consumption.
  • Oils and fats can be especially susceptible to rancidity because their chemistry can make them exceptionally susceptible to oxygen damage.
  • During oxidative rancidity, oxygen molecules interact with the structure of the oil and damage its natural structure in a way that can change its taste, its smell, and its safety for consumption.
  • Oxidative rancidity can be prevented by light-proof and airtight packaging and also by the addition of antioxidants.
