[Changes in the quantity of aldehydes, peroxides, the iodine and saponification number in bovine and swine fats following irradiation with gamma-rays].

The studies were carried out during the process of storing fats obtained from cattle and pigs under refrigeration conditions at plus and minus temperatures. The production of peroxides and epihydrinaldehyde in the fats after irradiation and during storage depended on the presence of oxygen, the rate of treatment, the temperature, and the period of storage. The intensity of production of peroxides and epihydrinaldehyde in the bovine fats was higher than in swine fats. Gamma-treatment at 2.00 Mrad had no effect on the changes of the iodine number and the index of saponification.
