In this study, the quality stability of a kind of natural seasoning material, the mixture of enzyme treated mackerel meat and Laminaria powder during the storage was investigated by measuring the TBA(thiobarbituric acid)value, extend of browning, changes in amino nitrogen and chlorophyll a, and fatty acid composition, and the results of sensory evaluation. Addition of sodium alginates (0.08%) and calcium carbonate (0.02%) seemed effective as a binder to yield clarity of the hot water extract of the product. In results, the mixture of Laminaria powder and the enzyme treated mackerel meat added with 0.08% sodium alginate and 0.02% calcium carbonate was more stable in overall quality than the other cases of preparation. And the taste of the mixture could favorably compete with that of dried anchovy extracts.

In order to develop a new type of natural seasoning material combining fish meat with seaweed, a processing method of the mixture of enzyme treated mackerel meat and Laminaria powder was studied. Mackerel meat previously boiled and deboned was treated with proteolytic enzyme to enhance taste of meat by proper hydrolysis. The enzyme-treated meat was dried at $100{\pm}2^{\circ}C$ for 4 hrs, and finally mixed with kelp power, moistened in advance, plus binding agents (0.02% calcium carbonate) to aid the formation of pellets by extrusion. Boiled mackerel meat of enzyme treated (0.03% Protease-A) at $50^{\circ}C$ for 90 min was adequate to result an increase in 6 times of total free amino acid content and about 10% increase of taste-enhancing amino acids such as glutamic acid, glycine, arginine, lysine.
