Analysis of cured pork loin ham quality using wet-aging and a pulsed electric field system

The effects on the quality of loin ham from using wet-aging with a commercial refrigerator (CR) and with a pulsed electric field system refrigerator (PEFR, at 0 and − 1 °C) were compared. The CR sample recorded an increased cooking loss alongside a decrease in color stability and shear force. In contrast, the samples using PEFR observed improved color stability, water holding capacity, and weight loss. In electronic nose analysis, wet-aging samples were shown to be significantly different from raw meat samples, however, the use of PEFR did not significantly affect the flavor. In electronic tongue analysis, wet-aging was observed to increase the umami of the loin ham, whilst the PEFR − 1 °C sample showed the highest umami. In sensory evaluation, the PEFR 0 °C sample showed significantly higher overall acceptability than raw meat. Conclusively, the application of wet-aging with PEFR in the manufacturing of loin ham led to an improvement in quality.
