Abstract
Food-compositions that are high in unsaturated fats and lipids which renders them prone to a short shelf life due to the development of rancid taste and off-color from the exposure to ultraviolet light are protected therefrom through the addition of an effective amount of tricalcium phosphate. The UV blocking agent can also be incorporated in the clear plastic packaging, glass and film wrap thereby shielding the food therein from the ultraviolet light in this manner.
