The Korea-EU FTA will provide korea with a significant advantage in the region both international trade and consumer welfare. Under the Korea-EU FTA, increasing of bilateral trade in consumer and industrial products would become duty and most remaining tariffs would be eliminated. This article studies on EU product price level of Korean consumer for before and after Korea-EU FTA effectuation. The questionnaires are sended 1,000 samples and 780 returns, 283 of them are analyzed for a this study. This paper has there main a parts, A Paired Samples Test result shows that the EU goods price level are positively affected by Flesh-meat, Electronic device & Electric home appliances, Kitchen utensils, Fruit juice(beverage), alcoholic liquors(wine, whisky), Clothes & Fashion. However, The Clothes & Fashion does not affect in EU goods price level, the Clothes & Fashion positively affected price differential more FTA effectuation before than FTA effectuation after.
This study was performed to determine risk ranking of the combination of pathogen-livestock or livestock products to identify the most significant public health risks and to prioritize risk management strategies. First, we reviewed foodborne outbreak data related to livestock products and determined main vehicles and pathogens according to the number of outbreak and case. Second, expert's opinion about management priority of pathogen-livestock product pairing was surveyed with 19 livestock experts in the university, research center, and government agency. Lastly, we used the outcome of Risk Ranger (semi-quantitative risk ranking tool) of 14 combinations of pathogen and livestock or livestock products. We have classified the combination of pathogen-livestock products into group I (high risk), II (medium risk), and III (low risk) according to their risk levels and management priority. Group I, which is the highest risk for foodborne outbreak, includes Salmonella spp./egg and egg products, Campylobacter spp./poultry, pathogenic E. coli/meat and processed ground meat. In conclusion, the results of this study will provide the specific guideline of mid- and long-term planning for risk assessment and risk management prioritization of the combination of pathogen and livestock, or livestock product.
The present study was carried out to investigate the effect of the partial freezing as a means of keeping freshness of mullet (Mugil cephlus). Living samples were killed and stored by icing, partial freezing at $-3^{\circ}C$ and freezing at $-30^{\circ}C$, respectively, Changes in the freshness of the mullet muscle and the phys cal properties of its meat paste product were examined during storage. The results obtained are summarized as follows: The period that k value reached to $20\%$ during storage was the longest in the frozen storage, followed by the partial frozen storage and the ice storage, which was 4 days in the mullet muscle stored by partial freezing. In the case of VBN content, it was below 20 mg/100g in the mullet muscle stored by icing and partial freezing. The oxidation of lipids in the mullet muscle was greater in the ice storage than in the partial frozen storage. The myofibrillar protein of the mullet muscle was appeared to decrease during storage, which the decreasing ratios during storage for 9 days were below $3\%$ in the frozen storage, $17\%$ in the ice storage and $10\%$ in the partial frozen storage. While, the alkali-soluble protein showed to increase and in non-protein nitrgenous compounds, sarcoplasmic protein and stroma was not a great change during storage. The decrease of gel strength, folding strength and texture of meat paste products prepared under different storage conditions was the greatest in the ice storage, the next in the partial frozen storage and such changes in the frozen storage were not so much. In gel strength of the product prepared with sample fishes stored for 10 days, the gel strength in the ice storage, partial frozen storage and frozen storage was about $30\%,\;60\%\;and\;97\%$ of the control. respectively. The expressible drip of the products increased with storage time of raw fishes, which that of the products prepared with sample fishes stored for 15 days was about 2.1 times in the ics storage, about 1.5 times in the partial frozen storage and about 1.1 times in frozen storage as much as that of the control, respectively.
After pigs was fed by commercial diets supplemented with various concentrations (0, 0.5, 1, and 1.5%) of the fermented mushroom by-product of Pleurotus eryngii, the meat qualities and the serum lipid compositions of the individual pig groups were investigated. The levels of total lipid, total cholesterol, and triglyceride in the serum were significantly lower when the pigs were fed with the diet supplemented with 1.5% fermented mushroom by-product than those of the control pigs. HDL-, LDL-, and VLDL-cholesterol contents in the serum exhibited no significant difference between the pig group fed by the diet containing the fermented mushroom by-product and the control group. In comparison to the control group, the pig group fed by the diet supplemented with 1.5% fermented mushroom by-product showed significantly lower level of AI, CRF, GOT, and LDH values in the serum, whereas the difference in the level of antioxidant activity of the serum was not significant. Sensory evaluation regarding color, off-flavor, tenderness, juiciness, and overall acceptability also showed that the pork from the pig group fed by the diet supplemented with the fermented mushroom by-product ($0.5{\sim}1.5%$) was better than that from the control group. Although enhancement in the lghtness ($a^*$) value of the pork was significant in 20 days of storage at $4^{\circ}C$, the redness ($L^*$) value was not significantly differential during the storage periods regardless of the supplementation of the fermented mushroom by-product into the diet. The cooking loss of the pork from the pig group fed by the diet supplemented with the fermented mushroom by-product (1% and 1.5%) decreased in the storage 10 days, but it increased in the storage 20 days. After storage for 20 days at $4^{\circ}C$, shear force of the pork obtained from the pigs fed by the diet supplemented with $1%{\sim}1.5%$ fermented mushroom by-product appeared to become significantly lower than that of the control. There were, however, no significant changes between two groups in the level of moisture content, crude lipid, and pH during the storage period. Although the TBARS content was enhanced in all groups during the storage period, the enhancement appeared to be more significant in the pork from the pig group fed by the diet containing the fermented mushroom by-product in comparison to the control. On the other hand, the ratio of UFA/SFA for the pork obtained from the individual pig groups showed no considerable diet-associated alterations during the storage period.

This study was carried out to prepare the flavoring substance using sardine for instant soup, and to examine the taste compounds and storage stability of the product. In preparation of product, raw sardine are gutted, boiled for 10 minutes and smoked 3 times to $9{\sim}10%$ moisture content at $80^{\circ}C$ for 8 hours. The smoked-dried sardine meat were followed to be 50 mesh of particle size. The powdered-dried sardine were mixed 4.0% sugar, 20.0% table salt, 3.0% monosodium glutamate, 0.2% black pepper, 0.2% garlic powder and 0.2% onion powder, Finally the powdered instant soup product were vacuum packed in a laminated film(PET/A1 foil/CPP) bag, and then stored at room temperature for 120 days. The effect of smoking on enhancing flavor and on preventing lipid oxidation of product during storage were observed. From the chemical analysis and omission test, the principal taste compounds of product were IMP, 478.2mg/l00g; free amino acids such as glutamic acid, histidine, arginine, phenylalaine 3292.5mg/l00g; non-volatile organic acids such as lactic acid, ${\alpha}-ketoglutaric$ acid, 712.2mg/l00g; total creatinine 409.0mg/100g, and small amount of betaine, TMAO. Fatty acid composition of product were mainly consisted of polyenoic acids such as 20:5, 22:6, followed by saturated acids, monoenoic acid. The major fatty acid were 16:0, 16:1, 18:1, 20:5 and 22:6. From the results of sensory evaluation and chemical experiments during storage, the vacuum packed product were good condition for preserving the quality during storage for 120 days. We may conclude that the quality of present product was not inferior to that of seasoning powder of anchovy on the market, and it can be commercialized as a flavoring substance in preparing soup and broth.

Very little information is available in the literature on storage of fish sauce. Therefore, microbiological and chemical chracteristics during storage and quality of fish sauce were investigated and discussed to present data about the optimum storage condition. The chopped sardine meat was mixed with equal amount of water and $9\%$(w/w) of $75\%$ vital wheat gluten and then hydrolyzed by addition of commercial proteolytic enzymes such as bromelain, papaya protease, ficin and a enzyme mixture (Pacific Chem. Co.) for 4 hours at $52.5^{\circ}C$. The reaction mixture was heated for 30 min at $100^{\circ}C$ for enzyme inactivation, pasteurization and color development and then centrifuged for 20 min at 4,000 rpm. Table salt and benzoic acid were added for bacteriostatic effect and stored for 80 days at $15{\pm}1^{\circ}C$ and $30{\pm}1^{\circ}C$. The results were summarized as follows: 1. The amount of amino-nitrogen and pH of fish sauce were almost unchanged during storage. 2. Mininum concentration of salt for bacteriostatic activity was $9\%$(w/w) regardless of addition of benzoic acid. 3. the yields of amino-nitrogen were $63.1\%$ for the hydrolysate prepared without enzyme, $79.7\%$ for that with bromelain, $69.9\%$ with ficin, $74.3\%$ with papaya pretense, and $78.1\%$ with enzyme mixture, respectively. 4. The contents of amino-nitrogen were $4510.0mg\%$ on the dry basis for the product prepared by autolysis, $5483.2mg\%$ for that prepared with bromelain, $5305.7mg\%$ with ficin, $4994.1mg\%$ with papaya protease and $5582.3mg\%$ with the enzyme mixture, respectively. 5. The contents of crude protein were $51.35\%$ on the dry basis for the product prepared by autolysis and 55 to $59\%$ for prepared with commercial enzymes. 6. The hydrolysate prepared with the enzyme mixture revealed a little stronger meaty taste than any other products. 7. The level of crude protein in residues was still high ($69.5{\sim}77.2\%$ on the dry basis) and might be originated from the added vital wheat gluten.

Squid (Todarodes pacificus) is processed as dried or seasoned-dried products and its catch gradually increased from 270,298 M/T in 2005 to 367,940 M/T in 2008 in Korea. Squid processing by-product (viscera) was usually discarded as a waste resulting in environmental problem. In order to utilize squid viscera for more value-added products, a natural squid seasoning was developed by fermenting with Aspergillus oryzae koji. Squid viscera at 5, 10 and 15% salt concentrations with fixed levels of 5% koji and 30% water was fermented at room temperature. The quality properties of squid fermented products such as amino-N, TMA, VBN, total viable cell count, pH and total acidity were determined at different fermentation periods. The contents of amino-N, TMA, and VBN of squid seasoning at 5% salt concentration fermented for 14 days were the highest. Based on amino-N content, squid viscera at 5% koji fermented for 14 days was selected for further assays: the content of moisture, crude protein, crude lipid, crude ash, and carbohydrate were 5.98, 35.19, 33.08, 11.30, and 14.45%, respectively. The content of glutamate, alanine, leusine and lysine were 7.06, 12.34, 9.90 and 10.22%, respectively. The $IC_{50}$ values of DPPH scavenging and $\beta$-glucuronidase inhibitory activity were 12.89 and 12.58 mg/mL, respectively. A natural squid seasoning was manufactured by mixing fermented squid viscera and an ingredient. Based on the results of sensory evaluation, the fermented squid viscera seasoning was almost equal to other natural complex seasonings such as anchovy, cow meat, and fisheries seasoning.

With the annual report of National Nutrition survey, the trend of food intake of Korean is analyzed from 1969 to 1989. Total food intake is about 1,000g. The amount of plant foods intake is decreased but the amount of animal food intake is increased. Among plant foods, the consumption of cereals and grain product and starch and starch roots is decreased gradually. The degree of decreasing are evident in the amount of cereal and grain product intake, The amount of vegetable intake is kept fluctuating, but the amount of processed vegetable products intake shows an upward trend. The amount of legumes and their products, vegetables, fruits and seaweeds intake is increased each year. In addition, among animal foods, the amount of meat and products, eggs, fish and shellfish and milk and milk products intake is increased greatly.
This study compared the college students' dietary behavior for processed foods, who will be the main consumers in the future and looked for the measures to understand and establish the right food labeling system by surveying the level of understanding and utilization of food labeling. The data was analysed by SPSS win 17.0 program, and the results are as follows. For the standard of selecting processed foods, the group with high nutrition knowledge considered the reliability of foods as important and the group with low nutrition knowledge considered the products introduced in TV commercial as important. When purchasing processed foods, the group with high nutrition knowledge considered nutrition, taste, price, appearance(shape), and the consumable period more than the group with low nutrition knowledge. For trans fat, the group with high nutrition knowledge learned more about it than the group with low nutrition knowledge. The ratio of confirming food nutrition label was higher in the group with high nutrition knowledge. Regarding the level of confirming individual food labels, the highest level was for milk and dairy products. And there was significant difference for the processed products of meat, cookies, bread and noodles. It was found that the level of confirmation was higher in the group with high nutrition knowledge. And the most important indication for individual food product was the consumable period. To preserve the purchased foods, the group with high nutrition knowledge preserve the foods in line with the description written on the food cover sheet, and this group used to return or exchange the products when they found them spoiled or purchased by mistake. The group with high nutrition knowledge knew more about the nutrition indication than the group with low nutrition knowledge. The necessity of nutrition indication for processed foods and the need of education and PR(Public Relation) were acknowledged higher in the group with high nutrition knowledge. For the effect of nutrition indication, it showed that the group with high nutrition knowledge thought it would improve the quality and the group with low nutrition knowledge thought it would be helpful when comparing the product with others. The group with high nutrition knowledge showed higher understanding level about nutrition indication than the group with low nutrition knowledge.
This study was conducted to investigate the productivity of Hanwoo steers by feeding self-product organic rice straw and concentrates(conventional, T1 and organic T2). Sixteen Hanwoo steers(8 months on the average) were randomly assigned to two treatment groups. Feeding trail was carried out in 2 treatment(8 heads/ treatment) by Hanwoo steers for 600 days form 8 to 28 months in age. The range of average daily gains of T1 and T2 were 0.76 to 0.77kg in the growing stage, 0.93 to 0.90kg in the first fattening stage, 0.99 to 0.84kg in the middle fattening stage, and 0.59 to 0.64kg in the latter fattening, respectively, and the gains for overall period was higher in T1 than in T2. Concentrates and total digestive nutrients(TDN)(T1) intakes per unit of kg gains were higher than T2 without significant difference. In carcass characteristics, the carcass weight in T1 were higher about 5% than in T2. According to the above results, it may be concluded that dry matter(DM) intakes, crude protein(CP) and TDN contents of feedstuff between treatments was no significant difference. but marbling in T2 score was higher than in T1 about 20%. There were no significant differences rib-eye area, back fat thickness and fat color(p>0.05).
