Effect of cysteine proteinase inhibitor containing fraction from chicken plasma on autolysis and gelation of Pacific whiting surimi
چکیده انگلیسی

The effects of cysteine proteinase inhibitor containing fraction (CPI fraction) from chicken plasma on autolysis inhibition and gelling properties of Pacific whiting surimi were investigated. The CPI fraction exhibited the inhibitory activity against autolysis of Pacific whiting surimi in a concentration-dependent manner. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis pattern revealed that the CPI fraction effectively prevented the degradation of myosin heavy chain, tropomyosin and troponin-T in Pacific whiting surimi incubated at 55 °C for 60 min as well as modori gel (55 °C for 30 min/90 °C for 20 min). The breaking force and deformation of modori gels increased as the concentration of CPI fraction increased up to 2.0% with a concomitant decrease in TCA-soluble peptides (p<0.05). However, a decrease in breaking force and deformation was noticeable with the modori gel added with 3% CPI fraction. The addition of CPI fraction had no detrimental effect on whiteness of surimi gels (p>0.05). The result suggested that CPI fraction would be an alternative additive for surimi containing the active cysteine proteinase causing the gel weakening.
