| Research Abstract |
ATP with physiological concentration showed strong suppressiveeffect on denaturation by the treatment of frozen, heat and acidic pH of fish muscle proteins which are myofibrillar protein, myosin s-1, sarcoplasmic reticulum and myoglobin. The autoxidation rate of tuna myoglobin was suppressed in the presence of ATP. The results indicate ATP has two functions, which are currency of energy and protein stabilizer. The ATP remaining in fish muscle works as a cryoprotectant during frozen storage.
