새로운 돔배기 절임공정을 개발하고자 상압과 감압하에 직간법과 물간법으로 염절임한 돔배기의 품질특성을 비교하였다. 무게 감소율은 물간법으로 상압하에서 절임 하였을 때 12.23%로 높았으며, 수분함량은 감압상태에서 물간법으로 절임한 돔배기가 65.46%로 높았다. 염함량은 직간법으로 감압상태에서 절임 하였을 때 3.02%로 높았으며, 보수력은 직간법으로 감압상태에서 절임한 돔배기가 60.2%로 높았다. 수분활성도는 상압상태에서 직간법으로 절임 하였을 때 0.926으로 낮았으며, 색차는 감압상태에서 물간법으로 절임한 돔배기가 9.75로 가장 낮았으며, 탄력성은 직간법으로 감압상태에서 절임한 돔배기가 91.7%로 높았다. 상압과 감압상태에서 절임한 돔배기을 비교하였을 때, 감압상태에서 절임한 돔배기의 품질특성이 더 좋은 것으로 나타났다. 따라서 감압상태에서의 절임법은 새로운 절임 가공 기술로 활용할 수 있는 가능성을 보였다.

We investigated the quality of Dombaeki (shark meat) treated without salting (NS), with salting (S), air-packed (A), and vacuum-packed (V), during storage at $4^{\circ}C$ and $-18^{\circ}C$. We explored water holding capacity, elasticity, total bacterial counts, pH, titratable acidity level, volatile basic nitrogen (VBN) value, and drip loss. Water holding capacity and elasticity values were better when salting and vacuum-packaging were employed than when samples were not salted and were packaged in air. The total bacterial counts in SV meat were significantly lower than in other samples. The pH of all samples increased slowly during storage, and the pH values of NSA samples were significantly higher than the pH values of other samples. The VBN level and drip loss of SV meat were the lowest of all samples during storage. The results show that salted vacuum-packed meat was of better quality than that stored without salting, and air-packed, regardless of storage temperature.

In previous paper (Lee et al., 1983) processing method of sardine meat "surimi" was described as a part of the wort to develop new types of ready-to-cook food materials with dark fleshed fishes. As the other part of the work, processing of low salt mackerel fillet was investigated, in this paper, in which fresh mackerel was filleted, salted in brine or with dry salt for an adequate time until the expected salt concentration reached, washed, air dried (3 m/sec, 15 to $20^{\circ}C$), and finally packed individually in K-flex film bag by vacuum or $N_2$ gas substitution. Salting time and salt concentration of brine was decided by the salt level penetrated into the fillet. As the final salt level was fixed to 4 to $5\%$, salting for 20 hours with $10\%$ dry salt or in $15\%$ brine at $5^{\circ}C$ was enough to get that level of salt. If the final salt level was set 5 to $6\%$, salting for 20-24 hours with $15\%$ dry salt or in $20\%$ brine was adequate. Salt penetration, however, was not much influenced by salting method and temperature. Changes in VBN and salt soluble protein occurred more rapidly in cases of salting with dry salt at $20^{\circ}C$ than salted in brine at $5^{\circ}C$, although it was not significant in the period of 20 to 24 hours. Oxidation of lipid and histamine formation during salting at $20^{\circ}C$ could not be neglected if it was delayed loger than 25 hours. Insolubilizing the salt soluble proteins during the storage of salted fillet occurred rapidly regardless of storage temperature. Browning and histamine formation, however, was depended on temperature and packing condition. In case of air pack, deterioration by browning and rancid was deeply developed but not the case for the packs by vacuum or $N_2$ gas substitution. The shelf-life of the salted mackerel fillet based on panel scores of brown color and rancidity, appeared 21 days for the air packed, and more than 30 days for vacunm or $N_2$ gas packed fillet at $20^{\circ}C$.
