The present work aimed to evaluate the combined influences of salt sodium chloride (NaCl) concentration and low-frequency ultrasound on the functionality of silver carp myofibrillar protein (MP). Silver carp MP was set using different salt concentrations (0.2 0.4 0.6 and 0.8 M NaCl) and low-frequency ultrasound treatment (12 min 350 W). The samples showed a high solubility (85.30 - 93.80) across various treatments. The turbidity was lowered significantly by increasing the salt concentration with no sonication while the turbidity changes were insignificant with the combination treatment (NaCl U12). Ultrasonic treatment of combined 0.4 M salt (NaCl 0.4 M U12) achieved the highest water holding capacity (WHC) making up 6.46 g water/g MP. The 2 2-diphenyl-1-picrylhydrazyl (DPPH) and 2 2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) inhibition ranged from 16.33 to 43 and 13.27 to 25.69 respectively and the highest values were shown in the sample containing 0.4 M salt with sonication (NaCl 0.4 M U12). It could be concluded that the best treatment was ultrasonic with 0.4 M salt (NaCl 0.4 M U12). The treatment provided the optimal antioxidant activity with good protein solubility and WHC. The integrated results indicate that employing NaCl with ultrasonic treatments (NaCl U12) could improve the functionality of silver carp MP. These results are very promising for increasing the potential advantage of this fish species as the sources of proteins for several applications.

Abstract

The present work aimed to evaluate the combined influences of salt sodium chloride (NaCl) concentration and low-frequency ultrasound on the functionality of silver carp myofibrillar protein (MP). Silver carp MP was set using different salt concentrations (0.2 0.4 0.6 and 0.8 M NaCl) and low-frequency ultrasound treatment (12 min 350 W). The samples showed a high solubility (85.30 - 93.80) across various treatments. The turbidity was lowered significantly by increasing the salt concentration with no sonication while the turbidity changes were insignificant with the combination treatment (NaCl U12). Ultrasonic treatment of combined 0.4 M salt (NaCl 0.4 M U12) achieved the highest water holding capacity (WHC) making up 6.46 g water/g MP. The 2 2-diphenyl-1-picrylhydrazyl (DPPH) and 2 2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) inhibition ranged from 16.33 to 43 and 13.27 to 25.69 respectively and the highest values were shown in the sample containing 0.4 M salt with sonication (NaCl 0.4 M U12). It could be concluded that the best treatment was ultrasonic with 0.4 M salt (NaCl 0.4 M U12). The treatment provided the optimal antioxidant activity with good protein solubility and WHC. The integrated results indicate that employing NaCl with ultrasonic treatments (NaCl U12) could improve the functionality of silver carp MP. These results are very promising for increasing the potential advantage of this fish species as the sources of proteins for several applications.
