초록

This study was carried out to investigate the effects on the quality and shelf-life of beef Hamburg patties. The patties composition, which used in the preparation of beef Hamburg patties is as the followings: Beef Tallow 20 Sodium 2(A), Beef Tallow 20 Sodium 2 Mugwort 1(B), Beef Tallow 20 Sodium 2 Mugwort 3(C) and were stored at -18$^{\circ}C$ for 30 days. The obtained results were summarized as the followings: The change of pH slightly decreased with increasing storage time. A(CON) decreased with increasing storage time, but the significant difference of pH changes were not shown between B(Mugwort 1%) and C(Mugwort 3%) group. The change of TBA values of all treatments increased during storage periods. The TBA value of A(CON) was the highest, and B(Mugwort 1%) was the lowest among groups. The change of VBN(volatile basic nitrogen) showed trends to increase during storage period in all groups. The number of microorganism increased during storage. The bacterial growth of C(Mugwort 3%) inhibited effectively, compared with the other groups. The number of E. coli decreased during storage periods. and the inhibitory effect of C(Mugwort 3%) was better than those of other groups.
