Product Description

A Pickering emulsion based on sodium starch octenyl succinate (SSOS) was prepared and its effects on the physicochemical properties of hairtail myofibrillar protein gels (MPGs) subjected to multiple freeze-thaw (F-T) cycles were investigated. The whiteness, water-holding capacity, storage modulus (G′) and texture properties of the MPGs were significantly improved by adding 1 %-2 % Pickering emulsion (P < 0.05). Meanwhile, Raman spectral analysis demonstrated that Pickering emulsion promoted the transformation of secondary structure, enhanced hydrogen bonds and hydrophobic interactions, and promoted the transition of disulfide bond conformation from g-g-g to g-g-t and t-g-t. At an emulsion concentration of 2 %, the α-helix content decreased by 10.37 %, while the β-sheet content increased by 7.94 %, compared to the control. After F-T cycles, the structure of the MPGs was destroyed, with an increase in hardness and a decrease in whiteness and water-holding capacity, however, the quality degradation of MPGs was reduced with 1 %-2 % Pickering emulsion. These findings demonstrated that SSOS-Pickering emulsions, as potential fat substitutes, can enhance the gel properties and the F-T stability of MPGs.
