A study on the water holding capacity of beef

The study was the investigation on the rate of the water holding capacity in the samples of 219 Korean native cattle, 38 Holstein-Friesian, 10 crossbreeding cattle and 8 cases of imported beef from Australia. After slaughter, 10gm of the beef each was taken from chuck, rib, loin, flank, round and rump in order to measure water holding capacity rate. The results obtained were as follows; 1. Results of water holding capacity rate in the beef were 76.2±0.87% in Holstein -Friesian, 75.73±0.19% in Korean native cattle, 75.08±0.94% in crossbreeding cattle and 74.49±0.75% in imported beef from Australia, respectively. 2. Results of water holding capacity rate in the parts of beef were 76.46±0.46% in round, 76.02±0.4% in rump, 76.01±0.28% in chuck, 75.49±0.38% in flank, 75.35±0.68% in loin and 75.12±0.54% in rib, respectively. 3. The water holding capacity rate of older Korean native cattle and Holstein-Friesian was Higher than that of younger cattle (P＜0.01). 4. The body weight of cattle showed the reverse proportion to water holding capacity rate of beef (P＜0.05).
