  • To elucidate the effect of protein films containing an antioxidant on lipid oxidation of fish paste products during storage, zein and soy protein isolate (SPI) films containing green tea extract were prepared and their physical properties were examined. Tensile strength and elongation of the protein films decreased by the addition of green tea extract compared to the control. Due to the addition of green tea extract, SPI film had an increase in yellowness, but zein film had a decreased yellowness. Wrapping of fried fish paste products by the zein and SPI films containing the antioxidant retarded lipid oxidation at 2 day storage by 3.6 mg MDA/kg sample and 3.6 mg MDA/kg sample, respectively, for instant fish paste compared to the control. For processed fish paste, they decreased the degree of lipid oxidation by 1.6 mg MDA/kg sample and 0.6 mg MDA/kg sample, respectively.

  • This study has been carried out in order to investigate the bacterial quality of fish meat paste products and the characteristics of isolated thermodurics from the products. Twenty samples of crab-flavored fish stick (Kematsal), 23 samples of plate fish meat paste (Panomuk, Kamaboko), 5 samples of fried fish meat paste (Tigimomuk), 2 samples of roasted fish meat paste (Puduromuk, Chikuwa), 20 samples of fish sausage were collected from processing plants and supermarkets in Pusan, Korea during the period from May to October in 1984. The results obtained are as follows. Amont the samples collected from supermarkets, roasted fish meat paste and fried fish meat paste marked hish counts in coliforms and fungi while very low in the samples of crab-flavored fish stick and plate fish meat paste. Salmonella was not detected in all the samples examined and Staphylococcus aureus was detected only in fried fish meat paste, Thermoduric bacteria were detected less than 10$^2$/g in the samples of crab-flavored fish stick and plate fish meat paste, which might come from subsidiary materials such as starch and seasonings. Among the isolated bacteria, distribution of the proteolytics were more than 87% and the lipolytics were less than 20%. Gram positive bacteria was more than 70% in crab-flavored fish stick and plate fish meat paste, 47.3% in fried fish meat paste. And rod in shape was almost more than 90% in all the samples. The most heat resistant bacterium isolated from the samples was identified as a Bacillus licheniformis(named B. licheniformis CR-11). The strain showed strong proteolytic activity and also grew well at above 2$0^{\circ}C$. The growth rate and generation time of CR-11 strain were 0.31 hr$^{-1}$ , 2.24 hr at 2$0^{\circ}C$, 0.64 hr$^{-1}$ , 1.09 hr at 3$0^{\circ}C$ and 0.78 hr$^{-1}$ , 0.89 hr at 35$^{\circ}C$. Heat resistance value of the spores of CR-11 strain suspended in phosphate buffer solution was D$_{85}$ $^{\circ}C$=41.9 min, D$_{90}$ $^{\circ}C$=27.9 min, D$_{95}$ $^{\circ}C$=10.2 min, D$_{100}$ $^{\circ}C$=4.3 min (Z=13.8$^{\circ}C$)

  • Thermal diffusivities of white muscled fish meat paste products were measured and an experimental equation for prediction of the thermal diffusivity was suggested. The thermal diffusivities of products with water contents of 43.03 to $82.49\%$ and lipid contents of 0.50 to $14.88\%$ could be deduced as following equations ; $$\alpha_{80.39^{\circ}C}=0.0832{\cdot}10^{-6}{\cdot}X_w+0.0797{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ $$\alpha_{100.63^{\circ}C}=0.0873{\cdot}10^{-6}{\cdot}X_w+0.0830{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ $$\alpha_{120.09^{\circ}C}=0.0842{\cdot}10^{-6}{\cdot}X_w+0.0901{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ From these equations, an experimental equation was derived for the prediction of thermal diffusivities of white muscled fish meat paste products ; $$\alpha=(1.308+0.1324{\cdot}X_w){\cdot}\alpha_w-0.0626{\cdot}10^{-6}{\cdot}X_w-0.1355{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ The errors of the thermal diffusivities predicted with this equation were less than ${\pm}\;0.30\%$ compared with those measured.

  • This study investigated the effects of the number of washes and alkaline treatments ($NaHCO_3$ concentrations) and the concentration of potato starch on the quality of fish meat paste products prepared from sand lance Ammodytes personatus Girard. We found significantly (P<0.05) higher ratings for the all textural parameters (hardness, brittleness, elasticity, and cohesiveness) of the sand-lance meat paste products (SLMPPs) that were washed three times with a 0.5% $NaHCO_3$ concentration. We determined that an 8% concentration of potato starch leads to the best textural properties in SLMPPs. As the amount of potato starch was increased, the redness values of SLMPPs decreased significantly (P<0.05), but the differences in the sensory evaluation parameters (texture, flavor, taste, and overall acceptability) between the SLMPPs were not significant.

  • To provide functional properties in fish paste, Styela plicata (Korean name: omandungi) having antioxidant and anticarcinogenic activity was added at 0, 5, 10, 15, and 20%. The fried fish pastes were investigated for color, textural properties, and sensory attributes. Fish paste containing 15% S. plicata showed the lowest values in lightness (L) and the highest values in redness (a) and yellowness (b). All test samples with 3 mm thickness had good flexibility and did not break even after folding 4 times. Fish paste containing 20% S. plicata showed the highest values in strength, hardness, and adhesiveness. In overall acceptance of sensory evaluation, fish paste containing 15% S. plicata acquired the highest score. These results support that S. plicata can be applied to fish paste products for the purpose of high quality and functionality.

  • Eh-jang (fermented aquatic products) of Asia can be classified 4 groups, those are Chot-kal (salted fish guts), Chot-kal Paste, Eh-ganjang (fish sauce) and Shic-hae (lactic acid fermented fish products). The native place of Eh-jang and rice culture is almost same and Eh-jang had been spread out all the area of Asia along with rice culture. Korea has variety of Chot-gal and consumes much Chot-gal that Korea is the culture area of both soybean sauce and Chot-gal. Eh-ganjang had been edible all area of Korea during Chosun Dynasty, but it remains only Southern part of Korea. Korean Chot-gal paste is produced as a form of Kon-chang-yi-chot. Korean Shic-hae had been edible all area of Korea during Chosun Dynasty, but remains at the east coast and some area of Hwang-hae Do and Kyung-sang-nam-do.

  • Fish paste containing Styela clava (Korean name: miduduk) was prepared for the supplementary value of the product, and it was evaluated for the color, textural properities, and sensory attributes. Increasing the amount of S. clava in the fish paste tended to increase the lightness (L), the redness (a), and the yellowness (b) in Hunter color values. All test samples with 3 mm thickness had good flexibility and did not break even after 4 times folds. Fish paste containing 20% S. clava showed the highest values in strength, hardness, and adhesiveness. In overall acceptance of sensory evaluation, fish paste containing 5% S. clava did not show any difference in comparison with non added control. These results suggest that S. clava can be applied to fish paste products to improve the quality and functionality.

  • The development of natural food preservatives instead of chemical synthetic food preservatives is world wide inte-rest. Authors already investigated that cinnamon bark extract revealed antimicrobial activity against general spoilage microorganisms of food especially its acitivity was stronger against molds than against bacteria. In this paper, authors examined the mirobial flora from the spoiled fish meat paste products and also checked the possibility of cinnamon bark extract food preservative for prolong the shelf life of the fish paste product and breads. The predominat bacteria was Bacillus sp. as about 98% of the total microorganisms isolated from unpacked or packed spoiled fish meat paste products. While molds and yeast are not detected from the vacuum packed products. The MIC(minimum inhibitory concentration) of cinnamon bark extract against the isolated spoilage bacteria and molds was 160~640$\mu\textrm{g}$/$m\ell$ and 40~80$\mu\textrm{g}$/$m\ell$, respectively. When the diluted cinnamon bark extract (the extract : ethanol=1 : 3) was sprayed on the surface of fried fish meat paste product, molds growth was delayed by 2 days at room temperature. The shelf lifes of sandwich and glutinousrice bread which surface sprayed with the diluted extract(1 : 1) was extended by 5 and 7 days, respectively.

  • In this paper, the influence of heating medium on the thermal diffusivities of fish meat paste products was studied. Model products were heated in boiling water, saturated steam and soybean oil. The differences in temperature raise of the products were interpreted with Biot number of the products. Because of the large overall heat transfer coefficient of heating medium, the temperature raise of the products in boiling water and saturated steam was fast and the Biot number of the products could be recognized as infinite. But the temperature raise of the products in soybean oil was slow and the Biot number of the products was less than 50.

  • To provide functional properties in fish paste, boiled-dried anchovy [small size (SS) and large size (LS)] powder containing high amount of calcium was added at 0, 1, 2, 5, and 10% (w/w) levels. The properties of fried fish paste were evaluated by determination of sensory properties and physicochemical characteristics such as color, texture, folding test, and calcium contents. Calcium content of the fish paste increased with increasing anchovy amount. Increasing the amount of SS and LS in fish paste tended to decrease lightness, redness in Hunter color value, while increasing yellowness. All samples with 3 mm thickness had good flexibility and did not break even after 4 times folds. The fish pastes containing 10% of anchovy showed the highest values in strength, hardness, adhesiveness. In overall acceptance of sensory evaluation, SS and LS fish paste containing 1% and 2% of anchovy powder did not show any difference in comparison with control. These results suggest that SS and LS anchovy powder can be applied to fried fish paste products to allow for high calcium contents.
