Wc. Ko et Ms. Hwang, CONTRIBUTION OF MILKFISH SARCOPLASMIC PROTEIN TO THE THERMAL GELATIONOF MYOFIBRILLAR PROTEIN, Fisheries science, 61(1), 1995, pp. 75-78
This research investigated sarcoplasmic protein (Sp-P) contribution to
the thermal gelation of meat paste and myofibrillar protein. The Sp-P
was recovered by an ultrafiltration unit from the wash water of milkf
ish meat paste preparations. Washed meat paste showed gel strength 1.4
-2.0 times that of unwashed paste. This may be caused by the concentra
tion effect of myofibrillar protein. Adding Sp-P increased gel strengt
h in both washed and unwashed meat pastes. The larger the amount of Sp
-P added, the stronger the effect. Suwari occurred at 40-50-degrees-C
and modori occurred at 60-70-degrees-C for milkfish meat pastes irresp
ective of the addition of Sp-P. Sp-P addition (10 mg/g) caused suwari
indices to change from 41 to 51, and modori indices from 37 to 33. The
se results show that the addition of Sp-P improves thermal gelation, h
as a promotive effect on suwari and a restrictive effect on modori.
