HPP can result in unwanted changes in fish products such as
acceleration of lipid oxidation, discolouration and cooked appearance
(Truong et al., 2015). The combination of HPP and freezing has
been studied to preserve mackerel and tuna muscle (Aubourg et al.,
2013; Ramirez-Suarez and Morrissey, 2006a) which improved the
texture, sensory and microbial quality of fish muscles without
causing the cooked appearance and lipid oxidation.
