2.1 3 2. Free fatty acids - fatty acids is in the form of Independent (free fatty acid) will be through oxidation is much easier than in the form of triglycerides (triglyceride)
2.1 3.3 quantity of oxygen and skin areas that will come in contact with oxygen oxygen to participate in reaction to the Oxford. If the food is in the atmosphere of a space or more oxygen skin contact with the oxygen, it will be a more rapid reaction.The oxygen removal from the packaging vacuum packaging (vacuum packaging), the packaging atmosphere conditions (modified atmosphere packaging) or removal of oxygen (oxygen scavenger) in packaging will help slow down the
