  • Experiments were carried out to establish an effective artificial drying method of Pacific saury (Cololabis seira) to kwamaegi. Raw fish containing 67% moisture were dried up to containing less than 40% moisture by drying for 15 days. The fish lost moisture more rapidly during first 3 days of natural drying than artificial drying. Total lipid content increased from 16.1% to 30.3 and 29.8% by 15 days of natural and artificial drying, respectively. Neutral lipid occupying 91.63% of total lipid increased to 92~94% during 15 days of drying, while content of phospholipid and glycolipid decreased slightly. The values of peroxide and thiobarbituric acid increased up to 6 days of drying and then did not change. Peroxide levels were lower in artifically dried fish than in naturally dried ones.

  • Pacific saury, Cololabis saira kwamaegi, is a traditional local food of the Eastern sea area centering around Pohang. It is well-recognized as being both tasty and nutritious. Nevertheless, bacterial contamination, excessive dryness, and compositional changes have made it edible only during the winter months. Therefore, to improve its storage, this study examined the effects of storage material, type, temperature, and duration on compositional changes in kwamaegi. The studied samples were kwamaegis that had been dried naturally for 15 days. The storage materials included an A-film, a self-developed multi-film made of polyethylene, polyamide, EVOH, and polyethylene; as well as a B-film made of polyethylene, nylon, polyethylene, nylon and polyethylene. The B films were used after pressing and laminating. The storage types included one whole fish(1G), or 2 divided fish(2G), to increase eating convenience. The 2G type was the muscle portion divided vertically after discarding the jowl, skin, and internal organs. The storage temperatures were $0^{\circ}C$, $-15^{\circ}C$, and $-30^{\circ}C$, and the storage durations were 2, 4, and 6 months. Pathogenic bacteria and rheology were measured to observe general compositional changes. The whole kwamaegi showed a total cell number of $1,565{\pm}112$ CFU/100 g flesh, while the divided Kwamaegi showed significantly greater bacterial numbers at $2,031{\pm}145$ CFU/100 g flesh. Psychrophils and halophils increased significantly while coliform were not found; the number of mesophils also increased, but not significantly. There were no significant cell number variations between the A-film and B-film. At $0^{\circ}C$, both the A-and B-films resulted in cell numbers of $115{\sim}212$ CFU/100 g flesh, revealing just $7.3{\sim}10.4%$ of the initial storage levels. Overall, there were no significant differences between the storage materials. Generally, as the storage temperature and duration increased, the moisture content of the kwamaegi decreased. Also, as storage duration and temperature increased, crude protein and crude lipid contents increased; in addition, they increased proportionally as the moisture content of the fish decreased. There were no significant differences in crude ash content with respect to the storage materials, storage temperatures, or storage durations. Finally, there were no significant differences between the kwamaegi samples naturally dried for 15 days and those stored in the B-film vacuum storage for 6 months for strength, hardness, cohesiveness, springiness, gumminess, and water activity.

  • Kwamaegi is a traditional Korean seafood made from the flesh of Pacific saury Cololabis saira. It is recognized as a valuable, healthy food containing the ${\omega}$-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). This study was conducted in order to obtain basic data for application to the canning process of Kwamaegi using red pepper paste with vinegar. Commercial Kwamaegi was cut into $2{\times}3cm$ lengths and 90 g was put into cans (301-3). Then, 60 g of water was added and precooked for 10 minutes at $100^{\circ}C$. The water was drained after precooking. The precooked Kwamaegi was packed into cans, and 60 g of red pepper paste with vinegar was added. The cans were seamed using a vacuum seamer, then sterilized for differing times (8-12 minutes) in a steam system retort at $121^{\circ}C$. Parameters such as: pH, TVB-N, amino-N, total amino acid content, free amino acid content, color value (L, a, b), texture profile, TBA value, mineral content, sensory evaluation and viable bacterial count of the product produced under varying sterilization times (8-12 minutes) were measured. There were no remarkable differences between sterilization conditions and textural characteristics. The results showed that product sterilized for 8 minutes proved to be the most desirable.

  • Quality characteristics of Kwamaegi (semi-dried saury) prepared by treatment of chitosan-ascorbate (CA) and vacuum drying at $40{\sim}60^{\circ}C$(VDK), and the effect of the Kwamaegi on serum lipid profiles and anti-oxidation-related enzyme activity in rats fed high fat diets were investigated. The preparation periods were $4.5{\sim}8.3$ hr in VDK, while naturally dried Kwamaegi (NDK) took 360480 hr. Total microbe contents of VDK and NDK were $0.2{\sim}0.5$ and 8.2 log CFU/g, respectively. There was no significant difference in amino-nitrogen content. Compared with NDK, the acid and peroxide value, and fishy flavor of VDK40 (dried at $40^{\circ}C$) were significantly lower, and the texture, color and overall acceptability were higher. In animal experiments, weight gain, content of LDL-cholesterol and lipid peroxide, activities of total (T) and O type (O) xanthine oxidase, and the O/T ratio (%) were significantly lower in the VDK40 diet group than in the NDK diet group. The content of HDL-cholesterol in the VDK40 diet group was higher than in the NDK diet group. These results suggest that preparing CA-treated Kwamaegi with vacuum-drying at $40^{\circ}C$ can be applied throughout the year, and may shorten preparation time and improve its microbiological safety and nutritional values.

  • The Pacific saury, Cololabis saira Kwamaegi, is a traditional local food of the Eastern sea area, centered around Pohang. It is well-recognized as being both tasty and nutritious. Nevertheless, bacterial contamination, excessive dryness, and compositional changes render this fish edible only during the winter months. Thus, to improve its storage capabilities, this study assessed the effects of storage material, type, temperature, and duration on compositional changes in Kwamaegi. The assessed samples were Kwamaegi which had been naturally dried for 15 days. The storage materials included an A-film, a self- developed multi-film made of polyethylene, polyamide, EVOH, and polyethylene, and a B-film made of polyethylene, nylon, polyethylene, nylon, and polyethylene. The B films were utilized after pressing and lamination. The storage types included one whole fish(1G), or 2 divided fish(2G), to increase eating convenience. The 2G type was the muscle portion divided vertically after discarding the jowl, skin, and internal organs. The storage temperatures were 0, -15 and $-30^{\circ}C$, and the storage durations were 2, 4, and 6 months. Among the lipid rancidities, acid value and peroxide value showed the highest level of initial rancidity at a storage temperature of $0^{\circ}C$ for 2 months. We noted no significant differences between storage materials. The lower the storage temperatures, the less acid and peroxide were generated. Between the storage types, 1G evidenced lower less acid values than 2G. The TBA values revealed a dramatic increase at a storage temperature of $0^{\circ}C$ for 2 months, whereas this rapid progress was not observed at storage temperatures of -15 and $-30^{\circ}C$. Along with the acid value and peroxide value, the samples stored at 0, -15 and $-30^{\circ}C$ evidenced significantly lower TBA values. The B-film evidenced a slightly lower TBA value than was observed in the A-film, but no significant differences were observed.
