Abstract

Sixteen somimembranosus muscles were seamed out from sixteen left carcasses. They were cut into $7{\times}10{\times}2cm$ pieces and mixed randomly. Samples were assigned to four treatments: (T1) soy-based sauce; (T2) Kimchi-based sauce; (T3) pickled shrimp-based sauce; and (T4) onion-based sauce. Each treatment was aged in plastic box at $1^{\circ}C$ for 10 days. These samples were vacuum-packaged after treatment with sauces and held in a chill at $1^{\circ}C$ for 28 days. The pH of aged port in general, was decreased significantly (p<0.05) with storage in all treatments. Its falling rate was the slowest in T4 of all treatments, while it was faster in T2 and T3 than in T4. The salinity of aged pork was decreased (p<0.05) for T2 with increased storage days, but increased (p<0.05) for T1. The salinity showed T2 to be significantly higher (p<0.05) than T1 and T4 on 1 day, but to be lower(p<0.05) than T1 on 28 day. The saccharinity of T3 was significantly higher (p<0.05) on 1 day than those of T1 and T4, but decreased (p<0.05) on 14 and 28 day. While saccharinity of T1 was significantly the lowest(p<0.05) of all treatments on 1 day and increased (p<0.05) with increased storage days. For T1 and T2, the WHC (water holding capacity) results showed higher (p<0.05) on 14 day than on 1 and 28 day. On 28 day, the WHC result showed T4 to be the highest(p<0.05) of all treatments, but T2 to be the lowest (p<0.05). On 28 day, the shear force results showed a big difference (p<0.05) among treatments, being in order of T4>T3>T2>T1. Panelists rated T1 as having higher(p<0.05) aroma, flavor and overall acceptability than other treatments.
