As an investigation for utilization of squid viscera oil as a food source, we attempted to improve a quality of fish burger by addition of emulsion curd formed from gelatin, water and refined squid viscera oil. Judging from the results of peroxide value, brown pigment formation, color value of Hunter, jelly strength and sensory evaluation, the reasonable amount of emulsion curd for the improvement of a fish burger functionality was determined as 6% on the weight basis of the chopped mackerel meat. Total plate counts, volatile basic nitrogen and histamine contents in fish burger prepared by addition of 6% of emulsion curd were $6.2{\times}10^4\;CFU/g$, 19.0 mg/100 g, and 50.7 mg/100 g, respectively. It may be concluded, from the above results that the emulsion curd-added fish burger is a safe as a food commodity. The ratio of polyenes to saturates of emulsion curd-added mackerel burger was 1.13. By adding emulsion curd formed from gelatin, water and refined squid viscera oil, color in cross section, texture and lipid functionality of mackerel burger could be improved in part.

For the effective untilization of mackerel as a food source, the most desirable processing conditions of mackerel based burger were investigated. The mackerel was beheaded, gutted, washed with tap water and deboned with the meat seperator. Then it was substituted with 15% pig meat and mixed with additives such as 18.3% emulsion curd, 3.0% soybean protein, 2.0% sodium chloride, 2.0% sugar, 0.1% monosodium glutamate, 0.2% polyphosphate, 0.4% sodium bicarbonate, 0.5% beef extract powder, 0.3% onion powder, 0.1% ginger powder and 0.1% garlic powder to a mixed meat. The seasoned mackerel based meat was molded to a thickness of 10 mm and a diameter of 80 mm, fried for 2 min. The examined mackerel based burger was superior to mackerel based burger by another processing conditions.

In the present paper, we investigated the quality stability of mackerel based burger during frozen storage. The moisture and crude lipid contents of products were $60.2{\sim}61.5%$ and $14.7{\sim}14.9%$, respectively. The pH showed a tendency of decrease, while volatile basic nitrogen content showed a tendency of increase during frozen storage. The histamine content was $2.60{\sim}2.81\;mg/100g$, and this value increased slowly during frozen storage. The increasing ratio in the peroxide value, carbonyl value, TBA value, fatty acid composition and color value of vacuum packed product and antioxidants added product were lower than those of air packed product. The texture profile analysis parameters such as hardness and toughness showed a tendency of a slight increase in air packed product and showed less increase in vacuum packed product and antioxidants added product. From the results of chemical experiments and sensory evaluation during frozen storage, it is concluded that the vacuum packed mackerel based burger and antioxidants added mackerel based burger were good condition for preserving the quality during frozen storage of 60 days.
