Effect of cold plasma on lipid oxidation of fish and fish‐based products: an invited review

Abstract

SummaryLipid oxidation is a major concern in preserving fish and its products, as it affects their quality, shelf life, and consumer acceptance. Cold plasma technology has emerged as a promising method for extending the shelf life of perishable products, including fish. However, the impact of cold plasma on lipid oxidation remains uncertain, as studies have reported conflicting findings. This review provides an up‐to‐date overview of the effects of cold plasma treatment on lipid oxidation in fish and fish‐based products, synthesizing existing literature in the field. A comprehensive analysis of factors such as plasma generation techniques, treatment parameters, fish species, and lipid composition is conducted to elucidate the observed discrepancies in outcomes. In conclusion, current research suggests that moderate oxidation does not have adverse effects on overall sensory quality and may even enhance the flavor of fish. The degree of oxidation can be controlled through plasma parameters, thereby improving the quality of fish and fish products.
