Effects of irradiation with gamma‐rays and electron beams on dehydrated blood plasma as well as heat treatment and fumigation were examined in terms of the sterility and functional properties to compare pasteurization techniques. Fumigation and irradiation reduced microorganisms in dehydrated plasma to less than 10/g, whereas heat treatment (63°C, 30 min) did not reduce microbe count below 1 × 10 3 /g. Fumigation lowered solubility of plasma proteins and heat treatment decreased emulsifying capacity considerably while gamma‐irradiation and electron‐irradiation did not significantly affect functional properties. Results indicated irradiation with gamma‐rays or electron beams was an efficacious blood plasma pasteurization method.
