This study investigated on the effects of adding mechanically deboned chicken meat (MDCM) hydrolysates on the quality properties of imitation fish paste (IFP) during storage. IFP was prepared from Alaska Pollack, spent laying hens surimi and protein hydrolysates which were enzymatically extracted from MDCM. The study was designed as a $3{\times}4$ factorial design with three MDCM hydrolysate content groups (0%, 0.4%, and 0.8%) and four storage times (0, 2, 4, and 6 weeks). Addition of MDCM hydrolysates increased crude fat content but lowered water content (p<0.05). The breaking force of IFP, an indicator of gel formation, increased in treated groups compared to control (p<0.05). Angiotensin I-converting enzyme (ACE) activity was inhibited and free radical scavenging activity increased with increasing MDCM hydrolysate content (p<0.05). In conclusion, the addition of MDCM to IFP improves gel characteristics. Additionally, protein hydrolysates from MDCM serve as a potential source of ACE inhibiting peptides.

Gastric cancer was inducedd by N-nethyl-N'-nitro-N-nitrosoguanidine(MNNG) in Fisher 344 male rats. Freeze dried typical Koran feeds, aged kimchi, soybean paste and maejoo, and partially scorched barbecued bulgokee were fed to the rat in the diet, which were composing 10% of the total diet. Experimental desing was as follows ; (1) group C : Control, (2) group M : MNNG with control diet, (3) group MK : MNNG with 10% of kimchi, (4) group MS : MNNG with 10% of soybean paste and maejoo, (5) group MB : MNNG with 10% of barbecued bulagokee, (6) group MKSB ; MNNG with 10% of the mixture of kimchi, soybean paste and maejoo, and barbecued bulgokee. Each group was fed with isocaloric diet for 26 weeks. Comparing to control, the growth rate of the experimental group was decreased after administration of MNNG and experimental diet. The mortality rate of group MB was increased by 17% than the control group along with a significant decrease of body weight. The protein efficiency ratio and the food efficiency ratio of group MB were lower than the control. The incidence of gastric cancer in rats fed kimchi and barbecued bulgokee were 73% and 75%, respectively, while that of group M which fed MNNG remained only 56%. On the contrary, soybean paste and maejoo showed an inhibitory effect on the burden of gastric tumor. However, the combination of kimchi, soybean paste and maejoo, and barbecued bulogokee showed a synergistic effect of increasing tumorigenesis in rats. Pathological observations of the rat stomach represent that squamous cell type tumors occupied in most frequencies.

Sardine and mackerel so called dark muscled fish have been underutilized due to the disadvantages in bloody meat color, high content of fat, and postmortem instability of protein. Recent efforts were made to overcome these defects and develope new types of product such as texturized protein concentrates and dark muscle eliminated minced fish. Approach of this study is based on the rapid dehydration of foamed fish-starch paste by dielectric heating. In process comminuted sardine meat was washed more than three times by soaking and decanting in chilled water and finally centrifuged. The meat was ground in a stone mortar added Ivith adequate amounts of salt, foaming agent, and other ingredients for aid to elasticity and foam stability. The ground meat paste was extruded in finger shape and heated in a microwave oven to give foamed, expanded, and porous solid structure by dehydration. Dielectric onstant $(\varepsilon')$ and dielect.ic loss $(\varepsilon")$ values of sardine meat paste were influenced by wavelength and moisture level. Those values at 100 KHz and 15 MHz were ranged 2.25-9.86; 2.22-4,18 for E' and 0.24-19.24; 0.16-1.20 for E", respectively, at the moisture levels of $4.2-13.8\%$. For a formula for fish-starch paste preparation, addition of $20-30\%$ starch (potato starch) to the weight of fish meat, $2-4\%$ salt, and $5-10\%$ soybean protein was adequate to yield 4-5 folds of expansion in volume when heated. Addition of e99 yolk was of benefit to micronize foam size and better crispness. In order to provide better foaming and dehydration, addition of $0.2-0.5\%$sodium bicarbonate, foaming agent, was proper to result in foam size of 0.5-0.7 mm and foam density of $200-400\;/cm^2$ which gave a good crispness. Heating time was depended upon the moisture level of fish-starch paste. For a finger shaped paste (1.0cm. $D\times10cm.L$) heating for 150-200 sec. in a microwave oven (700W. 2.45GHz) was sufficient to generate foams, expand, and solidify the porous structure of fish-starch paste. When the moisture content was above $55\%$ browning and scorching was deepened due to over-expansion and over-heating whereas the crispness was hardened by insufficient expansion at lower moisture content. In quality evaluation of the product, chemical composition of $30\%$ starch and $3\%$ salt added product was moisture $8.8\%$, lipid $2.4\%$, carbohydrate $46.7\%$, protein $36.1\%$, and ash $6.0\%$. Eleven membered panel test evaluated that fish-starch paste was acceptable in color, crisp-ness, taste, except a trace of fishy odour which could be masked by the addition of spice extracts.

This study was undertaken to evaluate the change of major nutrient components in boiled broth of anchovy, fish paste, sea tangle, and radish subjected to the boiling processing. The crude protein, fat, ash, and carbohydrates in anchovy boiled broth were 0.1%, 0.04%, 0.1%, and 0% respectively as against 0.04%, 0.1%, 0.2%, and 0.4% in fish paste boiled broth. The protein content in the anchovy boiled broth, the fat and carbohydrate in the fish paste boiled broth, and the ash in the sea tangle boiled broth were high. Major components of the minerals were sodium plus potassium and the boiled broth in anchovy and fish paste had the contents of 19.41 plus 16.19 and 76.77 plus 10.41 mg, respectively. Especially, the potassium in boiled broth of the sea tangle was shown the highest content of 85.94 mg. The Vitamin B1 content in all broth samples were below 0.01 mg per 100 g edible portion. In the case of the B2 content, the anchovy boiled broth had 0.03 mg per 100 g edible portion. On the other hand, the niacin content of the boiled broth on a wet weight basis was detected at an average 0.1 mg. Vit. A, C, tocopherol, and cholesterol was not detected in the boiled broth of any of the subjects. As a result of applying the data of boiled broth in the fish paste soup instead of anchovy and sea tangle which are non-edible, the calcium, dietary fiber, and vitamin A were shown to have a difference of less than 50%.
