매쇄 정어리 육에 정어리 자가 소화액 및 정어리 코오지를 첨가하여 발효 숙성시키므로서 질소 함량이 높고 풍미가 양호한 숙성 정어리 제조조건을 검토하였다. 정어리 자가 소화액의 제조조건은 마쇄한 정어리육에 $80\%$ 가수한 후 $55^{\circ}C$에서 180 r.p.m.으로 교반하면서 6시간 자가소화 시키는 것이 적합하였다. 속성 정어리 액젓 제조를 위한 식염 농도 및 발효 온도는 각각 $15\%$ 및 $40^{\circ}C$가 적당하였으며 마쇄정어리 육에 자가 소화액 및 정어리 기질 코오지를 각각 $10\%$ 첨가하고 식염, 밀가루, 정어리 자가 소화액을 각각 $15\%$, $10\%$ 및 $150\%$ 비율이 되도록 혼합한 후 $40^{\circ}C$에서 15일간 발효시키므로서 향미가 양호하고 질소함량이 높은 속성 정어리 액젓을 제조할 수 있었다.

Young male rats were fed for 10 and 20 days on different low-fat experimental diets ; 4% lard + 4% soybean oil, 4% sardine oil + 4% lard, 4% sardine oil with vitamin E+ 4% lard, 4% sardine oil with vitamin E+ 4% soybean oil. Lipid peroxide levels in liver were significantly higher in the sardine oil groups but the addition of vitamin Ehad no effects on the lipid peroxide values. Serum total cholesterol showed no significant difference among the groups but HDL-cholesterol in serum was increased in the sardine oil groups. However, the contents of serum triglyceride and phospholipid were unaffected by the replacement with sardine oil.

In order to establish the processing condition of salt-fermented liquefaction of sardine (Sardinops melanoslicta), effect of temperature, pH value, and concentration of salinity on crude enzyme activity of sardine viscera were investigated. The optimum temperature range of crude enzyme activity in sardine viscera was $45{\sim}50^{\circ}C$ and the optimum pH value of it was 9.8. According to the concentration of salinity increased the crude enzyme activity in sardine viscera decreased. The relationship between concentration of salinity (X) and the crude enzyme activity (Y) in sardine viscera is shown as follows; Y=-0.01363X+0.7676 (r=-0.88). For the purpose of processing conditions of rapid- and low salt-fermented liquefaction of sardine, changes of viable cell count, histamine content, and volatile basic nitrogen (VBN) in the chopped whole sardine with 8% NaCl during preheating process at $40^{\circ},\;45^{\circ}$ and $50^{\circ}C$ for 48 hrs were analyzed. During preheating, initial viable cell counts of chopped whole sardine were $10^{4-7}/g$, but they decreased $10^{1-5}/g$ after 48 hrs. Histamine contents during preheating process at $40^{\circ}\;and\;45^{\circ}C$ were gradually increased, whereas at $50^{\circ}C$ were almost the same level after 48 hrs. VBN contents were continuously increased during preheating, but preheating at $50^{\circ}C$ samples were lower level than that of $40^{\circ}\;and\;45^{\circ}C$ ones. For the purpose to accelerate the fermentation and liquefaction of chopped whole sardine, preheating at optimum temperature of crude enzyme activity for 48 hrs was useful processing method and the contents of viable cell count, histamine, and VBN were safety level for food sanitation.

Sardine oil was microencapsulated by spray drying method in wall systems containing corn syrup in combination with sodium casein or wheat protein. Analysis of microencapsulation yield of sardine oil was carried out by a modified soxhlet method which could reduce the extraction time of surface oil. Microencapsulation yield of sardine oil was ranged from 65.3 to 93.5 % depending on the sodium casein content.

정어리를 원료로 하여 통조림과 레토르트파우치제품을 제조하여 제조시 가열살균시간의 차이와 저장중 제품의 품질을 비교 검토하였다. 정어리레토르트파우치제품은 통조림에 비해 가열살균시간을 $20\%$ 단축시킬 수 있었다. 휘발성염기질소, 아미노질소, 및 산값은 통조림제품과 레토르트파우치제품 모두 제조 및 저장중 증가하는 경향이었고 제품간의 차이는 거의 없었다. 과산화물값은 제품 제조 및 저장중 증가하였으나 저장 90일 이후 감소하였고 통조림제품이 레토르트파우치제품보다 약간 높은 값을 나타내었다. TBA값은 제품 제조 직후 상당히 감소하였고 저장중에는 서서히 증가하는 경향이었다. 저장 60일째부터는 통조림제품이 레토르트파우치제품보다 약간 높은 값을 나타내었다. TMA는 제품 제조시 많이 증가하였고 저장중의 변화나 제품간의 차이는 거의 없었다. IMP함량은 두 제품 모두 $8.39{\sim}9.80{\mu}mole/g$의 범위로 제조 및 저장중 뚜렷한 제품간의 차이나 함량의 변화를 찾아볼 수가 없었다. 지방산조성은 제품의 제조 및 저장중 폴리엔산이 약간씩 감소한 반면 모노엔산이 증가하였으며 그 변화폭은 통조림제품이 다소 컸다. 텍스튜어는 경도(hardness)가 통조림에 비해 레토르트파우치제품이 약간 높았고 toughness, 탄성(elasticity)및 응집력(cohesiveness)은 제품간의 차이는 거의 없었다. 색조는 레토르트파우치제품이 통조림제품보다 약간 밝았다. 저장중 텍스튜어와 색조의 변화는 두 제품 모두 거의 없었다. 관능검사결과 색, 냄새, 조직감, 맛 및 종합평가의 모든 면에서 $1\%$는 물론 $5\%$의 유의수준에서도 제품간의 유의차는 없었다. 정어리레토르트파우치제품은 통조림에 비해 손색이 없다는 결론을 얻었다.

This study was performed to investigate the effect on polyunsaturate fatty acid diets and feeding periods on the antithrombosis. the hematological changes in the blood and fatty acid compositions of platelets in rats. Each group of rats was fed a diet containing 20%(W/W) corn oil beef tallow sardine oil and the general stock diet for 10, 20. 40 and 80 days. Rats fed sardine oil diet showed significantly longer bleeding time than any other diet groups after 20 days feeding The whole blood clotting time of sardine oil group fed for 80 days was increased significantly. The number of platelet and the concentration of hemoglobin showed no significant difference among all groups. The number of white blood cell was decreased continously in sardine oil group after 10 days feeding. The level of malondialdehyde generation during thrombin-induced aggregation of platelets was decreased continously in sardine oil grou after 20 days feeding. With regard to the composition of platelet fatty acid the ratio of eicosapentaenoic acid(EPA 20: 5 $\omega$-3) to arachidonic acid(AA 20:4 $\omega$-6) was increased in sardine oil group but decreased in corn oil groups and beef tallow groups with days. In conclusion the rats fed sardine oil diet for more than 20 days showed the fact that EPA induced the antithrombosis. the changes in number of white blood cell and the fatty acid composition of platelets.

This study was attempt to improve the quality of rapid- and low salt-fermented liquefaction of sardine (Sardinops melanoslicta). Effect of pretreatment methods such as water adding, heating, and intermittent NaCl adding on fermented liquefaction of chopped whole sardine were investigated. The divisions of the experimental samples by pretreatment methods were as follows; Sample A (water adding and heating): chopped whole sardine adding 20% water and then adding 3 and 5% NaCl consecutively at the intervals of 3 and 6 hrs during heating for 9 hrs at $50^{\circ}C$ and then fermented at $33^{\circ}C$ for 90 days. Sample B (preheating): chopped whole sardine with 8% NaCl and heating at $50^{\circ}C$ for 9 hrs and then fermented at $33^{\circ}C$ for 90 days. Sample C (control): neither pretreatment methods of water adding nor preheating on chopped whole sardine with 13% NaCl and then fermented at $33^{\circ}C$ for 90 days. Comparison of the appropriate fermentation period, yield of hydrolysate, chemical composition of fermented liquefied products were carried out. The highest content of amino nitrogen appeared at 60 days in the sample A, 75 days in the sample B, and 90 days in the sample C during the fermentation period. The appropriate fermentation period of the sample A was shorten 15 days than the sample B and 30 days than the sample C in the processing of sardine. The product A was lower NaCl (8.5%) and lower histamine content (25mg/100g) than the sample B and C. Possibly, three kinds of pretreatment methods such as water adding, heating, and intermittent NaCl adding, might be recommend as the processing of rapid- and low salt-fermented liquefaction product of chopped whole sardine.

This research was to investigate the effects of sardine oil with different antioxidants on tissue lipid peroxidation and the activity of superoxide dismutase in rats. Young male rats were fed for 6 weeks on different experimental diets containing 10% (w/w) sardine oil with $\alpha$-tocopherol (800mg / kg oil), $\delta$-tocopherol(1, 000mg / kg oil) or rosemary extract(1, 000mg /kg oil) as antioxidant and also sardine oil lard without antioxidant as control. In sardine oil group tissue lipid peroxide level and percentage of hemolysis were increased compared to those of lard group. By the addition of antioxidants, percentage of hemolysis reduced significantly but the lipid peroxide level in liver was unaffected. The activities of superoxide dismutase in erythrocyte and liver were not affected by either sardine oil ingestion or different antioxidants.

우리나라 사람들의 기호에 맞으면서 저장성이 있는 정어리 조미가공품의 제조를 위하여 초절임 중 품질변화에 대하여 실험하였다. Dressed한 정어리를 포화식염수에 염지한 결과 48시간까지는 수분함량의 경우 감소하였고, 염도, 휘발성염기질소함량 및 조직감의 경우 증가하였으나, 그 이상의 시간에는 거의 변화가 없었다. 정어리 초절임중에는 수분 및 회분은 거의 변화가 없었고, pH는 상당히 감소하였다. 가공 중 생균수는 감소하였고, histamine함량은 변화가 없어 식품위생적으로 안전하다고 판단되었다. TBA값, 과산화물값 및 지방산조성의 결과로 볼 때 염지한 정어리를 항산화제가 함유되어져 있는 조미액에 초절임하여 제조하는 경우 가공 중 지질산패가 상당히 억제되었다. 정어리 초절임제품의 맛성분은 함량으로 미루어 보아 신맛의 유기산과 histidine, lysine, glutamic acid 및 arginine과 같은 유리아미노산 그리고 IMP와 같은 핵산관련물질이 맛의 주체를 이루고, 총 creatinine, betaine 및 TMAO 등이 보조적으로 맛에 관여하였다.
