Recent developments in non‐thermal processing for seafood and seafood products: cold plasma, pulsed electric field and high hydrostatic pressure

Abstract

Summary Seafood and seafood products (SSPs) are highly perishable foods due to their chemical composition (high moisture content and nutrients). They are regarded as highly sensitive to different processing technologies. SSPs are subjected to various processing conditions with intent to extend their shelf life, quality and minimal nutritional degradation. Recently developed non‐thermal technologies (NTTs) have proved their efficacy in inactivation of microorganisms and enzymatic activities, enhancing the shelf life while maintaining the nutritional quality. Considering the significant impacts of NTTs on shelf life extension and maintaining quality parameters, it has attracted considerable interest by scientific communities and commercial applications in some cases. Thus, this article focuses on recent developments in the application of NTTs namely, cold plasma, pulsed electric field and high hydrostatic pressure as well as advantages and limitations of NTTs. In addition, their impacts on microbiological, physicochemical, quality and safety of SSPs are elucidated.
