Seven selected commercial pure or refined olive oils were obtained from the market, and their physicochemical properties and volatile characterizations were investigated. Fatty acid profiles of the analyzed olive oils showed oleic $(61.2{\sim}74.7mole%)$, palmitic $(10.2{\sim}16.8mole%)$, linoleic $(9.4{\sim}18.0mole%)$, stearic $(1.9{\sim}3.0mole%)$, palmitoleic $(0.7{\sim}2.4mole%)$ and linolenic acid $(0.5{\sim}0.9mole%)$. According to Hunter#s color measurement, pure or refined olive oils showed $L^*$ value of $92.2{\sim}99.0$, $a^*$ value of $-22.2{\sim}-3.2$, and $b^*$ value of $18.5{\sim}55.0$. Their total phenol contents ranged from 1.9 to $13.3mg/100g$ while ${\alpha}-tocopherol$ content showed $7.91{\sim}13.88mg/100g$. Oxidation stability of the pure or refined olive oils were observed by Rancimat. The induction period ranged from 17.37 to 34.72 hr while their POV were $6.83{\sim}20.31meq/kg$ oil. Electronic nose and gas chromatograph-mass spectrometry with head-space solid phase microextraction were applied to identify and discriminate the volatile compounds and flavors in pure or refined olive oils, respectively.

This survey was conducted to assess the consumer perceptions of food-related hazard in 500 housewives from all over Korea. The subjects were selected by stratified random sampling method. The survey was performed using structured questionnaire through telephone interview by skilled interviewers. The results showed that 34.6% of the respondents felt secure and were not concerned about food safety, and 65.4% were concerned about food safety. Logistic regression analysis showed that the increasing concern on food brands, food additives (such as food preservatives and artificial color), and imported foodstuffs indicated the current increasing concern on food safety. Other related factors indicating the increasing concern on food safety were education level and care for children's health. The respondents who cared about food safety expressed a high degree of concern on processed foodstuffs such as commercial boxed lunch (93.3%), imported foods (92.7%), fastfoods (89.9%), processed meat products (88.7%), dining out (85.6%), cannery and frozen foods (83.5%), and instant foods (82.0%). The lowest degree of concern was on rice. All the respondents perceived that residues of chemical substances such as pesticides and food additives, and endocrine disrupters were the most potential food risk factors, followed by food-borne pathogens, and GMOs (Genetically Modified Organisms). However, these results were not consistent with scientific judgment. Therefore, more education and information were needed for consumers' awareness of facts and myths about food safety. In addition, the results showed that consumers put lower trust in food products information such as food labels, cultivation methods (organic or not), quality labels, and the place of origin. Nevertheless, the respondents expressed their desire to overcome alienation, and recognized the importance of knowing of the origin or the producers of food. They identified that people who need to take extreme precautions on food contamination were the producers, government officials, food companies, consumers, the consumer's association, and marketers, arranged in the order of highest to lowest. They also believed that the production stage of agriculture was the most important step for improving the level of food safety Therefore, the results indicated that there is a need to introduce safety systems in the production of agricultural products, as follows: Good Agricultural Practice (GAP), Hazard Analysis and Critical Control Point (HACCP), and Traceability System (75).

Identification of animals has been made with an ear tag with dummy code, and blood typing has been used for paternity and individual identification in live animals. As various genetic markers are for different cattle breeds vary, the discrete genetic markers are necessary to identify Hanwoo. A total of 740 progeny testing Hanwoo were used to identify Hanwoo specific markers. To examine traceability of individuals by using breed specific genetic codes, four animal were randomly sampled, and traced from live animals to post-slaughter processing stages. The candidate genetic makers used in the study were 16 DNA microsatellites which were identified in romosomes 1 and 14. The number of alleles of those DNA microsatellites ranged from a minimum of 3 to maximum of 12. The heterozygote frequency ranged from 0.022 to 0.824. Effective number of alleles for each DNA microsatellites were 3 to 6. Six selected candidate genetic markers were able ti trace individual cattle with an 100% confidence level.

2009년은 그야말로 새옹지마(塞翁之馬 : 인생에 있어서 길흉화복은 항상 바뀌어 미리 헤아릴 수 없다)와 같은 한 해로 기억에 오래 남을 듯 하다. 2008년 말에 2009년 양돈산업을 전망할 때 미국발 금융위기에도 불구하고 국내산 돈육 공급량 부족과 환율상승 및 급변으로 인한 돈육 수입량 부족, 그리고 수급 불균형으로 대부분의 전문가들이 역대 최고의 돈가를 예상했고, 실제로 3월에 지육가격이 5,000원/지육kg(전국 비육돈 평균시세)을 상회하면서 성수기에 돈가가 6,000원/지육 kg에 육박할 것이라 기대했었다. 그러나 4월 미국에서 발생한 신종인플루엔자가 초기에 돼지에서 유래된 인플루엔자라고 보도되면서 돈육소비량이 급감하였고 이로 인해 성수기에 돈가가 오히려 하락하는 기현상을 보였다. 다행히 신종플루가 돼지와 무관하다는 사실이 밝혀지면서 소비가 회복되었고 돈가 또한 회복되어 올해는 역대 최고의 돈가가 형성될 것으로 예상되고, 여기에 국제곡물시세가 안정되면서 사료가격도 여러 차례 인하되어 양돈 농장의 수익성은 상당부분 향상될 것으로 판단된다. 하지만 신종플루 사망자가 증가하면서 지금도 여전히 돈육소비가 위축되어 있어 막연히 호황을 기대하기 쉽지 않은 실정이다. 돈가의 급등과 급락, 외부요인에 의한 경제환경의 변화로 인한 환율의 변동 및 소비량의 변화는 2009년 양돈산업에 대한 불안감을 증폭시켜 높은 돈가와 수익성에도 불구하고 전체 산업의 규모가 커지지는 못했다. 여기에 국산 돈육에 대한 소비자들의 무한 신뢰로 인해, 2008년 12월 돈육 원산지 표시제 확대 실시로 국내산 돈육 수요가 증가 하여 여전히 75% 가량의 국산 돈육 자급율을 유지함에도 불구하고 아직까지 맛의 차별화 및 도축, 유통의 안전성에 대한 확고한 신뢰 구축을 위한 브랜드 돈육 유통의 확대가 소비자의 기대치만큼 자리 잡지 못하고 있는 실정이다. 또한 친환경적인 양돈산업 육성 및 분뇨 처리 관련하여도 뚜렷한 해답을 찾지 못하고 있어, 양돈 농가의 입장에서는 규모의 확장 및 신규 진입이 극도로 제한되어 있고 일부 지역에서는 사업의 존폐를 결정하는 주요 원인이 되고 있다. 그간 대한민국 양돈 산업의 경쟁력에 발목을 잡고 있던 낮은 생산성 문제와 소모성 질병에 의한 높은 폐사율 문제 또한 아직도 여전히 해결되지 못한 과제이다. <그림 1> 국가별 양돈 농장 생산성 현황에서 보는 바 와 우리나라 양돈 농장의 생산성은 여전히 PSY(모돈당 연간 이유자돈 두수)가 18두에 못 미치고 있어 국제 경쟁력을 논하기 자제 가 부끄러운 실정이다. 여러 가지 내 외부적인 어려운 환경에도 불구하고 올 2009년은 양돈농가들이 최고의 수익성을 기록한 한 해가 될 것이라는 사실에는 이의가 별로 없을 듯하다. 2년 여간의 고돈가로 인해 대한민국 양돈산업은 새로운 도약을 위한 밑천이 마련된 셈이라고 할 수 있다. 본고에서는 2009년 양돈산업 현황을 돌아보고 다가올 미래를 준비한다는 의미에서 우리나라 양돈산업이 집중해야 할 분야를 짚어보고자 한다.

This study analyzed the Importance-Performance Analysis of selective attributes of Home Meal Replacement (HMR). This study was conducted using a primary field survey on department stores and wholesale markets in Seoul and Gyeonggi province. A total of 201 out of 234 questionnaires were analyzed. First, the highest intake frequency was 1~3 times a month (100 respondents: 48%), the most common purchasing place was wholesale market (148 respondents: 73.6%), and the most cited reason for preference was convenience (115 respondents: 57.2%). According to the IPA results, selective attributes with low satisfaction and high importance in the second quadrant were 'quality', 'health', 'hygiene', 'origin of food', and 'safety'. These results suggest that the microbiological and sensory qualities of HMR production should be improved to meet consumer's expectations.
