The use of the polymerase chain reaction (PCR) method was described using two sets of primers based on the ceuN gene (JEJ 1 and JEJ 2) which encodes a protein involved in siderophore transport and 16S rRNA gene (pA and pB) for the sensitive and specific detection of enteropathogen Campylobacter jejuni. Six oligonucleotides were utilized in an amplification experiment and PCR products of predicted sizes were generated from whole cells and boiled cell lysates at the same intensity. Two sets of the primer pairs, JEJ and pAB, were specific enough for all C. jejuni strains tested for the direct use of whole cells without DNA extraction or lysis steps. In the PCR using the pAB primer pair, the detection limit, as determined by the ethidium bromide staining of the amplification products on agarose gels, was at the level of $10^1$ bacteria cells or less in both the pure culture and artificially inoculated milk and chicken enrichment samples, whereas the detection limit with the JEJ primer pair was relatively low, i.e. $10^3$ cells or more in the same PCR samples. The PCR method using either a primer JEJ or pAB was both repeatable and specific for the detection of C. jejuni in food. This method is simply completed within 4 h.

This study is focused on developing traditional folk products by utilizing the representative crops and indigenous products of Wanju area on the basis of surveys on the visitors to the native local restaurants. The study examined 110 visitors of thirty native local foods restaurants in Wanju area from December 5, 2007 to January 5, 2008. The result of this study is as follows. First, the restaurant visitors presented different opinions about the competitiveness of Wanju foods and gender-wise differences in their food competitiveness, food information and food choice. This can be translated as men and women had different preferences in how much they spend for eating out and choosing foods. Second, their different age, incomes and jobs also indicated their different preferences. Third, they point out broth, cooked rice, and dessert as the native local menu that must be developed in Wanju area. Among the local menu to be developed were Wanju style mushroom rice, chicken stew, oriental herb duck soup and fruit dessert.

To evaluate the methanol extract from Pinus strobus leave as a possible ingredient of health food, the sensory analysis and an animal experiment were designed using cookie, candy or chewing gum containing the methanol extract. Cookie, candy and chewing gum which contained 0.4%, 0.25% and 0.3% of the methanol extract, respectively, were prepared by Haitai Confectionary CO.. Sensory analysis of the products was evaluated by hedonic scale. Our results indicated that the addition of the methanol extract to the products provides better sensory perception in hedonic score and higher preference number than control, especially in candy and cookie. In the animal experiment, the chickens fed diet containing 10% of the cookie powder for 2 weeks exhibited a reduction of the serum cholesterol level by 18%, compared with the chickens fed basal diet. This result suggested that the methanol extract from P. strobus leave contained a potential ingredient to reduce the concentration of serum cholesterol. Therefore, extract from Pinus strobus leaves can be used as an ingredient of health food.

Demand for alternatives to petroleum is increasing the production of biofuels from food crops such as corn, soybeans, sorghum and sugarcane, etc. At least for the next 5 years, ethanol demand will be increased greatly in the United States and in the world. Presently, most ethanol produced in the United States is corn (Zea mays) ethanol. As a result, especially in the Americas and Southeast Asia, agricultural land is diverted to biofuel production. Even though biofuel industry has many advantage including national security, economical, energetical and sustainable impacts, it is driving grain prices up and creating considerable concern about the potential negative impacts on a wide range of food products that depend on gain : chicken, pork, beef, and dairy products such as milk, cheese, yoghurt, cream and ice cream. Feedstock crops are crops such as switchgrass(Panicum virgatum, L.), corn stover and grasses that can be used in industrial processes such as fermentation into alcohol fuels. Feedstock is no compete with food. Furthermore it is friendly environmental bioenergy crops. In Korea, with increasing demand for fossil fuels the exploration of alternative sources of liquid fuel is inevitable. I suggest Korea need to research and to develop actively on feedstock for biofuel production through this review.

This study was carried out to compare the cut meat yields of Cobb and Avian and their profits at productive aspect. Two different breeds, Cobb (34,086,758 birds) and Avian (4,087,600 birds) produced from January 2009 to August 2009 were used. The whole chickens were divided into cut meats including tenderloins, breast fillets, whole wings, boneless thighs, and drumsticks. The growth performance and cut meat yield of Cobb and Avian were measured to investigate possible profit difference. Cobb was superior in the aspect of production performance to Avian with significant differences in survival rate and slaughtering age. As the weight gained, the yields of Cobb increased in breast fillets and boneless thighs as well as lean meat percentage. Significantly higher yield (%) of breast fillets was produced by Cobb at size 14 when compared with Avian. However, there was no significant difference in expected market prices for both cut meat and whole chicken meat between the two breeds in all sizes.

This study investigated the effects of a healthy image on the preference and intake frequency of meat and animal products. The study looked into beef, pork, chicken, sausage, mackerel, cutlass fish, croaker, tuna, squid, shrimp, clams, fish cakes, eggs, milk, yogurt, ice cream, and cheese. A total of 359 usable surveys given to elementary school students, college students, and adults were collected using a convenient sampling method. While milk had the healthiest image, sausage had the least healthy image. The respondents preferred yogurt the most and sausage the least. The intake frequency of eggs was the highest and clams the lowest. The healthy image, preference, and intake frequency for all studied foods showed significant differences across both gender and age. The relationship between healthy image and preference was significant for all foods, and a healthy image always had a positive influence on preference. The relationship of healthy image and intake frequency was significant in 14 foods except for mackerel, cutlass fish, and tuna. Also a healthy image created a positive effect on the intake frequency of 14 foods.
