Influence of Multifrequency Ultrasound-Assisted Freezing on the Flavour Attributes and Myofibrillar Protein Characteristics of Cultured Large Yellow Croaker (Larimichthys crocea)

Abstract: The influence of multifrequency ultrasound-assisted freezing (UAF) as compared with single- and dual-UAF on the flavour, microstructure, and myofibrillar proteins (MPs) of cultured large yellow croaker was investigated to improve food quality in a sustainable way and address the major global challenges concerning food and nutrition security in the (near) future. Multifrequency UAF-treated samples had lower total volatile basic nitrogen values during freezing than single- and dual-UAF-treated samples. Thirty-si… Show more

“…As a non-thermal food processing technique, ultrasound has been widely applied in various fields of food processing such as crystallization ( 14 ), hydrolysis ( 15 ), extraction ( 16 ), and microbial inactivation. Compared with the conventional thermal techniques, the ultrasound technique presents many advantages such as no chemical residues, minimal thermal effects, and less influence on food quality ( 17 ).…”

“…In addition, in terms of the maximum fluorescence emission wavelength (λ max ), the λ max of the control group (334 nm) was higher than 330 nm, indicating that tryptophan was in a polar environment ( 41 ). The larger the redshift of λ max , the larger the conformational change of the protein.…”

“…Ice crystal growth also results in an increase in the concentration of solutes within the cell, which can further concentrate pro-oxidants and accelerate oxidative denaturation of proteins, thereby promoting the production of carbonyl groups [ 28 ]. What is more, the primary and secondary lipid peroxides (malondialdehyde) can probably interact with MP to generate carbonyl groups [ 29 ]. After seven F-T cycles, the control group exhibited the highest carbonylation level at 1.58 nmol/mg, which was substantially different from FI and BHA addition groups ( p < 0.05).…”
