Effects of four kinds of phosphate complex on the water holding capacity(W.H.C) and protein solubility of yellow-corvenia(Pseudosciance manchurica) and hair tail(Trichurus lepturns) meat paste were investigated. The formulations of four kinds of phosphate complex employed to this experiment were made by mixing several phosphates such as sodium polyphosphate, sodium pyro-phosphate, sodium acid pyro-phosphate, potassium pyro-phosphate, sodium tetra meta-phosphate, sodium ultra meta-phosphate and sodium hexa meta-phosphate, and monoglyceride at different mixture ratios. Among the four kinds of phosphate complex, phosphate B complex which was formulated by mixing sodium poly-phosphate 50%, sodium pyro-phosphate 20%, sodium tetra meta-phosphate 20%, sodium acid pyrophosphate 5% and sodium ultra meta-phosphate 5% was most effective on enhancing the W.H.C and protein solubility of yellow corvenia meat paste, and in case of hair tail meat paste, phosphate C complex which was formulated by mixing sodium poly-phosphate 40%, sodium pyro-phosphate 30%, potassium pyro-phosphate 15%, sodium tetra meta-phosphate 10%, and sodium hexa meta-phosphate 5% was more effective than other phosphate complex, and their optimum addition level was 0.4% respectively in weight of fish meat paste. Texture characteristics such as hardness, cohesiveness, and springiness value of Kamaboko(fish meat paste product) were evaluated as best when 0.3% of phosphate B complex was added. The optimum cooking condition of Kamaboko to get good texture was heating for 45 minutes at 85$^{\circ}C$.

The purpose of this study was to develop a kelp (Laminaria japonica) product with optimal sensory and nutritional properties for eating as a snack by investigating its physicochemical properties and conducting sensory evaluation. A preliminary study using tripolypolyphosphate solution found that it was good for removing the fishy smell and for making it soft. We soaked the kelp in 0.3-0.4% sodium tripolyphosphate buffer and tested with or without baking. In searching for the optimal polyphosphate dilution concentration, soaking in 0.3-0.4% sodium tripolyphosphate resulted in the best texture and flavor. As kelp separates into thick or thin samples, thick kelp was best when soaked in 0.4% sodium tripolyphosphate buffer and thin soaked in 0.3%. The kelp snack made from the thick one (over 221 mm thickness) was better than the thin one. Baking improved the moisture, texture and feel of the kelp snack. Tripolyphosphate treatment affected protein contents and texture softening. The differences by baking and tripolyphosphate treatment were shown with electromicroscopic image. Kelp snacks with added sweet and hot taste were preferred to sour taste. In conclusion, in making kelp snacks, it is advisable to use a thick kelp, 0.3-0.4% sodium tripolyphosphate, and baking treatment for better texture and feel. This kelp snack has low fishy smell, better taste and soft feel. Further research is needed to support sea food's importance, and usefulness of the kelp snack to help prevent goiter in inland province citizens.

The processing conditions of low salt mackerel (Scomber japonicus) fillet was investigated, in which fresh mackerel was filleted, salted in brine until the expected salt concentration reached, dried with cool air (3 m/sec, $10{\sim}20^{\circ}C$), and finally packed individually in polyvinyl chloride film. Salting time and salt concentration of brine decided the final salt level penetrated into the fillet. As the final salt level was fixed to $0.8{\sim}1.0%, salting for $15{\sim}20 hours with 5% or 10% brine at $5^{\circ}C$ was enough to get that level of salt. Formation of histamine during salting was negligible. Changes in VBN, salt soluble proteins, and histamine formation of salted mackerel fillet during the storage occurred more rapidly in cases of storage at $5^{\circ}C than af $-2^{\circ}C and $-20^{\circ}C. Oxidation of lipid during the storage progressed, however it was delayed longer then 100 days in case of storage at $-20^{\circ}C. Addition of sodium erythrobate or ginger extracts could provide some extent of browning retardation. The shelf-life of the salted mackerel fillet based on panel scores of brown color and rancidity appealed to be 14 days when stored at $5^{\circ}C, and more than 28 days in case of storage at $-2^{\circ}C and about 3 months stored at $-20^{\circ}C.
