Sensory characteristics wereestimatedafter2and6weeksbyatest panel (Fig. 2). Colour, aroma, taste, texture and general aspect of the HHP-treated sausages were consistently less favoured after 2 weeks as compared to the non HHP-treated sausages, for salami (Fig. 2a) as well as for morr (Fig. 2c). Differences in the sensory characteristics between the HHP- and non HHP-treated sausages were less marked after 6 weeks maturation, for salami (Fig. 2b) as well as for morr (Fig. 2d). Freezing of raw material produced a slight improvement of finalsen sorycharacteristicsoftheHHP-treatedmeatproducts.Thisim provement was more noticeable after 6 weeks for salami as well as for morr. It has been reported that freezing of beef carpaccio prior to HHP treatments helps to maintain its chromatic parameters (Szerman et al., 2011). Low-temperature HHP of frozen beef meat has also been suggested to prevent colour degradation as the fresh meat normal colour is recovered after thawing (Fernandezet al., 2007). Results from triang letests (resul tsnot shown) also showed that the test panel diffe rentiated between samples that were processed with and without HHP, and also between refrigerated HHP and frozen HHP samples (salami and morr, both after 2 and 6 weeks). After 2 weeks maturation the test panel preferred refrigerated salami and morr over refrigerated HHP salami and morr (p ≤ 0.05). The test panel also preferred frozen HHP salami and morr over refrigerated HHP salami and morr. After 6 weeks maturation these differences were no longer so evident, and only the difference between HHP refrigerated salami and HHP frozen salami was still significant, the panel lists still preferred frozen HHP salami. The samples were treated with 600 MPa during 6 min. It isreported that pressures above 400 MPa cause the myoglobin to denature and may result in oxidation of unsaturated lipids (Bak et al., 2012; Ma & Led ward, 2013). Substantial optimizing of the process is necessary to makeHHP pre-processed trimmings relevantin the market. Reduction of pressure level without compromising the safety and controlled
