Popis: A theory is set forth for the mechanism of rancidification which is based on a disrupted photosynthesis in the case of vegetable oils and on the photosensitizing action of haemoglobin or other animal pigment that may be present in small amounts in animal fats such as lard. Nascent hydrogen is believed to be liberated from the photosensitizer (chlorophyll or animal pigment) which unites with molecular oxygen to form loosely combined or nascent hydrogen peroxide. This unstable peroxide unites with the unsaturated bond of the tri-glyceride to form a glyceride peroxide which in turn splits into an aldehyde and forms the rancid compound.
