  • For the development of probiotics in aquaculture of marine organisms, three strains having psychrophilic and salt tolerant characteristics were isolated from Kimchi. Amng the isolated strains. MG19, MG89 and MG208 were identified as Lactobacillus brevis, Enterococcus faecium and Lactobacillus plantarum, respectively. The neutralized culture broth of isolated strains were tested in order to evaluate the antibactrial activity, 조초 showed high antibacterial activity against Edwardsiella tarda, Vibrio cholerae andPseudomonas fluorescens. In mixed culture of pathogens and isolated strain,pathogens were signifi-cantly inhibited after 2 days of cultivation but the isolated strains showed normal growth. When the Edwardsiella tarda was cultured with three isolated strains, its growth was completely inhibited after 254 hours of cultivation. The effect of isolated three strains as probiotics was investigated based on the changes in body weight of aquacultured flounder. After 50 days feeding trial, it was found that the mean body weight gain of the tested group fed freeze-dried isolated cells was significantly greater than that of the control group. These results suggest that these isolated strains can play an important role as probiotics in aquaculture.

  • Before Jin (秦) period, Oriental (Eastern) culture was established in Korea different from China. Bulgogi (babecued beef, 貊炙) and legume fermented soy were transmitted into China. Afterward, alcohol drink, rice cake and cookie, shic-hae (lactic acid fermented fish products), Kimchi (fermented vegetable) were introduced and modified for Korea. Buddhism was transmitted to Korea through China, but selective animal was used as food. Later period of Koryo Dynasty, meat-eating become common due to mongorian influence and distilled spirits was introduced by mongorian. During Chosun Dynasty, table setting of spoon and chopstick was established, due to Confucian influence, dog eating, raw fish and raw meat eating became popular and nutrition for elderly was developed, whereas tea culture declined. In recent period (under the Japanese rule) Chinese introduced chinese noodle, chinese cuisine, chinese pancake and sun-dried salt. many chinese cultivated chinese vegetables.

  • Two experiments were conducted to evaluate the use of fish silage prepared from Indian oil sardines, Sardinella longiceps, as partial replacement of soybean meal as a sole source of protein for growing broiler chickens. The main objective of Experiment 1, an ileal digestibility assay, was to assess the nutritional value of fish silage compared with soybean meal for feeding broiler chickens. The two test ingredients, soybean meal and dried fish silage, were incorporated into semi-synthetic diets, as the only component containing protein. The ileal digestibility coefficients of amino acids of fish silage were considerably higher than those of soybean meal (p<0.001). The lower digestibility of amino acids from soybean meal was related to the presence of anti-nutritional factors such as trypsin inhibitors. Fish silage had higher levels of sulphur-containing amino acids than soybean meal. The objective of Experiment 2, a growth study, was to evaluate the effect of feeding fish silage on performance and meat quality characteristics of broiler chickens raised under closed and open-sided housing systems. Four diets containing various levels of fish silage (0, 10, 20 and 30%) were evaluated. Daily feed intake, body weight gain and feed conversion ratio were measured. At the end of Experiment 2, 96 birds were randomly selected and slaughtered to evaluate meat quality characteristics. Housing type had significant effects on feed intake and body weight gain (p<0.01). Birds in the open-sided house consumed 4.7% less amount of feed and gained 10.6% less than their counterparts in a closed house. Birds in both houses fed diets containing 10 and 20% fish silage gained more than birds fed 30% fish silage. The current study produced evidence that fish silage can replace up to 20% of soybean meal in broiler diets without affecting either growth performance or the sensory quality of broiler meat.

  • Hatchery waste including infertile eggs, dead embryos in shell, dead or low grade chicks was cooked at $100^{\circ}C$ for 15 minutes and then oven dried and ground. Hatchery waste meal (HWM) thus prepared contained 44.25% protein, 4,573 kcal/kg gross energy, 3,600 kcal/kg metabolizable energy, 30% ether extract, 1.9% fibre, 14% ash, 9.8% nitrogen free extract, 7.26% Ca, 0.84%P, 1.86% lysine and 0.66% methionine with no Salmonella and E. coli. In biological evaluation trial, significantly higher weight gain was observed in ration containing 12% HWM compared with that containing similar amount of fish meal. Protein efficiency ratio on the two rations was 3.96 vs 2.85; protein digestibility, 86.02 vs 71.9; net protein utilization, 64.9 vs 42.37 and biological value, 75.37 vs 58.84, respectively, indicating better balance of amino acids in HWM compared with fish meal. Growth performance trial on broiler chicks also revealed better weight gain and feed efficiency on ration containing 12% HWM than that containing similar level of fish meal.

  • We proposed perfect recycling method of sea waste. The sea waste(rotten sea fish, rotten shell fish etc.) have bad smell and generate waste water, so these waste materials must be treated quickly. If we use speedy dryer, these sea waste can be changed to useful feed and liquid composts. Also this study relates to a method for drying a variety of untreated waste materials in a hermetically sealed state, and subsequently carbonizing the dried waste materials under a reduced pressure, thereby achieving a more stable and economical treatment for the waste materials, and an apparatus for performing the method. This effects of preventing generation of contaminants and environmental pollution while reducing fuel costs, and a carbide, obtained via the drying and carbonization of the waste material, are available into feed for poultry. The condensate water can be used to deodorants.

  • The aims of this study is to analyze the purchasing behavior of customers purchasing seafood using internet shopping mall based on the sales data of Suhyup Shopping Mall in 2016. The research shows three facts. First, 46.1% of those customers marine products in Suhyup Shopping Mall are purchasing less than 2 times a year and 62.7% of them are purchasing less than 5 times a year. Seconds, The amount of purchases of marine products using Suhyup Shopping Mall is very small. The proportion of purchasers with less than ₩100,000 per year is 48.5%, and the proportion of customers with annual purchases of less than ₩300,000 is 68.2%. Last, Relatively strong items were found by region and age. Abortion was a relatively strong item in the 20s, and In the 30s, the aquatic product set was a relatively strong item. In the 60s are seashells / scallops / shellfish and other fish, 70s are dried yellow croaker, abalone, tile fish and other fish. In the 60s and 70s, the other fishes showed strong relative strengths in terms of quantity and amount. But There were no relatively strong items due to regional differences according to the metropolitan area and nonmetropolitan area.

  • This study was carried out in order to investigate protein cross-linking in freeze-dried meat of flounder (Limanda herzensteini). Changes in solubility or extractability of proteins and electrophoretic patterns of the extracted proteins were determined to monitor the cross-linking during the storage of freeze-dried meat. Development of nonenzymatic browning and the loss of in vitro protein digestibilily were also measured to assess their influences on the changes of functional and nutritional properties of proteins. In addition, the effects of lysine added, and removal of fat and water extractives were also mentioned. The extractability of protein decreased upon storage time and temperature, and the loss of solubility of myosin was evident. In case of the samples stored at $5^{\circ}C$ for 150 days, the extractability of protein decreased $26.4\%$, while that of the samples stored at $20^{\circ}C$ for 60 days decreased about $39.7\%$. And it was noted that the loss of solubility of myosin was $68.3\%$ and $98.1%$ for the same storage conditions, respectively. It was noteworthy that the samples treated with $L-lysine{\cdot}HCl$ seemed to prevent more or less the loss of protein solubility, in that, even stored at $20^{\circ}C$ for 120 days, revealed only $57.03\%$ decrease. The nonenzymatic browning was proceeded with the increase of storage temperature, especially, in the samples treated with glucose. This suggests that the decrease in extractibility of myosin was accompanied by the extent of browning. But the browning was retarded in defatted samples. The in vitro apparent protein digestibility was also higher in the samples defatted or water extracted. It was suggested from these results that changes in properties of proteins in freeze dried fish meat were led by the protein cross-linking which was attributed to Maillard type of reactions and protein-lipid interactions.

  • The browning development, mainly through the Maillard reaction, occurring in the dried fish meat products during storage causes reduction of the nutritional value due to the loss of the essential amino acid such as available lysine as well as off -flavor resulting in the deterioration of the food quality thus shortening the shelflife. In the work, the changes in the amount of available lysine, extractable nitrogenous compounds (nonprotein-N, amino-N, trimethylamine oxide, trimethylamine, and free lysine) and development of browning were measured to assess the relationship between the shelflife and the quality loss in dried filefish under the steady state conditions (35,45, and $55^{\circ}C;a_{w}'s$ of 0.44 0.52, 0.65 and 0.75 at each temperature) and fluctuating temperature condition of $35/55^{\circ}C$ will. alternating 7 day periods at each water activity. The results indicated that the amount of available lysine and extractable nitrogenous compounds except TMA decreased rapidly with increasing temperatures and water activities while the rate of available lysine and extractable nitrogenous compounds must be involved in the initial stage of brown pigment formation. The available lysine loss of the dried filefish products stored under the fluctuating temperature conditions was greater than that stored under its fixed mean temperature, $45^{\circ}C$. The activation energies for lysine loss obtained from the Arrhenius plot ranged 6.9 to 4.4 Kcal/mol and $Q_{10}$ values at $40^{\circ}C$ were 1.4 to 1.2. The values for browning were 15.7 to 14.4 Kcal/mol and 2.2 to 2.0 respectively. Shelf-life, defined as the time to reach 0.15 O. D./g solid or the limit of off-color deterioration by browning reaction, was extented longer than the halflife of Iysine loss, actually corresponding $75\%$ loss of available lysine. This suggested that the halflife of lysine loss might not be adequate to assess the shelf-life of the food system with high potential of protein, nonproteinous nitrogen compounds, and lipids.
