To gain insight on cheese consumption and develop strategies for the cheese industry, we conducted a survey of 742 women (age 25 or older) who were responsible for purchasing food for their families. Of them, 49.5% consumed cheese more than once a week and 25.1% expected that the cheese consumption of their families would increase, whereas only 7.1% expected a decrease in consumption. The most important considerations for purchasing cheese were taste and price. Of the respondents, 40.6% purchased domestic cheese, whereas 49.1% were unconcerned about the country of origin. Of them, 20.6% had experience of purchasing farm-made cheese, and 62.7% of them were satisfied with the cheese. These results suggest that cheese consumption will increase in the future, and that with attention to quality improvement and advertising, domestic farm-made cheese consumption could increase accordingly.

Korea dairy industry has a long and chronic problems to consume raw milk , those are surplus milk and decline the market milk consumption continued about 10 years. This study was aim to propose and to find the solution for dairy industry problems. After WTO system, with the importation of dairy products, domestic milk production has fell into the situation of excess supply and huge inventory of dried milk, the milk powder stocks have increased since 2002. That made a chronic decline milk consumption in Korea. The core of chronic problem of Korea dairy industry is the decreasing in market milk consumption. If they have a settlement of any other way using their raw milk to process and consumption to market milk, there will be a solution to solve the chronic problems in this situation. Especially, that will be a development of small farm scale natural cheese production and consume. This may be lead a situation of increase the raw milk consumption, because natural cheese making needs much of raw milk more than market milk. But there are very low technical level of farmers cheese making status, so they need a cheese making educational program for their commercial level of cheese products. Under these situation, there are needed a way out of educational system for the dairy farmers to obtain the high level of cheese making technology from the trustable and scientific organization. The natural cheese making technique of dairy farmers should be accumulated to get the consumers' solid recognition of high quality of natural cheese as LOHAS(Lifestyle Of Health And Sustainability) foods.

One of the most critical issues in the dairy industry, alongside the low birth rate and the aging population, is the decrease in demand for milk. In this study, the consumption trends of 12 major dairy products distributed in Korea were predicted using a logistic model, the Gompertz model, and the Bass diffusion model, which are representative S-shaped growth models. The 12 dairy products are fermented milk (liquid type, cream type), butter, milk powder (modified, whole, skim), liquid milk (market, flavored), condensed milk, cheese (natural, processed), and cream. As a result of the analysis, the growth potential of butter, condensed milk, natural cheese, processed cheese, and cream consumption among the 12 dairy products is relatively high, whereas the growth of the remaining dairy product consumption is expected to stagnate or decrease. However, butter and cream are by-products of the skim milk powder manufacturing process. Therefore, even if the consumption of butter and cream grows, it is difficult to increase the demand of domestic milk unless the production of skim milk powder produced from domestic milk is also increased. Therefore, in order to support the domestic dairy industry, policy support should be focused on increasing domestic milk usage for the production of condensed milk, natural cheese, and processed cheese.

Cheese is generally considered a safe and nutritious food, but foodborne illnesses linked to cheese consumption have occurred in many countries. Several microbial risk assessments related to Listeria monocytogenes, Staphylococcus aureus, and Escherichia coli infections, causing cheese-related foodborne illnesses, have been conducted. Although the assessments of microbial risk in soft and low moisture cheeses such as semi-hard and hard cheeses have been accomplished, it has been more focused on the correlations between pathogenic bacteria and soft cheese, because cheese-associated foodborne illnesses have been attributed to the consumption of soft cheeses. As a part of this microbial risk assessment, predictive models have been developed to describe the relationship between several factors (pH, Aw, starter culture, and time) and the fates of foodborne pathogens in cheese. Predictions from these studies have been used for microbial risk assessment as a part of exposure assessment. These microbial risk assessments have identified that risk increased in cheese with high moisture content, especially for raw milk cheese, but the risk can be reduced by preharvest and postharvest preventions. For accurate quantitative microbial risk assessment, more data including interventions such as curd cooking conditions (temperature and time) and ripening period should be available for predictive models developed with cheese, cheese consumption amounts and cheese intake frequency data as well as more dose-response models.

BACKGROUND/OBJECTIVE: It is expected that dairy products such as cheeses, which are the main source of cholesterol and saturated fat, may lead to the development or increase the risk of cardiovascular and metabolic diseases; however, the results of different studies are inconsistent. This study was conducted to assess the association between cheese consumption and cardiovascular risk factors in an Iranian adult population. SUBJECTS/METHODS: Information from the Isfahan Healthy Heart Program (IHHP) was used for this cross-sectional study with a total of 1,752 participants (782 men and 970 women). Weight, height, waist and hip circumference measurement, as well as fasting blood samples were gathered and biochemical assessments were done. To evaluate the dietary intakes of participants a validated food frequency questionnaire, consists of 49 items, was completed by expert technicians. Consumption of cheese was classified as less than 7 times per week and 7-14 times per week. RESULTS: Higher consumption of cheese was associated with higher C-Reactive Protein (CRP), apolipoprotein A and high density lipoprotein cholesterol (HDL-C) level but not with fasting blood sugar (FBS), total cholesterol, low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and apolipoprotein B. Higher consumption of cheese was positively associated with consumption of liquid and solid oil, grain, pulses, fruit, vegetable, meat and dairy, and negatively associated with Global Dietary Index. After control for other potential confounders the association between cheese intake and metabolic syndrome (OR: 0.81; 96%CI: 0.71-0.94), low HDL-C level (OR: 0.87; 96%CI: 0.79-0.96) and dyslipidemia (OR: 0.88; 96%CI: 0.79-0.98) became negatively significant. CONCLUSION: This study found an inverse association between the frequency of cheese intake and cardiovascular risk factors; however, further prospective studies are required to confirm the present results and to illustrate its mechanisms.

The taste preference for cheese is primarily dependent on an individual's habitual experience, such as personal memories since childhood. Cheese is not a traditional food in Korea, and therefore, the liking of cheese is acquired mainly through the exposure to European natural cheese by frequent travels rather than habitual experience. Although Korean dairy farms started the production of European style natural cheese because of surplus milk undulation, yet its demand has been consistently increasing in the last decade. Most of the mountain cheese variety in Europe are produced during the summer season on mountain pastures, especially in countries surrounded by the Alps. Nevertheless, not only consumers but also mountain cheese producers cannot comprehensively explain the differences in the nutritional properties of the milk from cows that grazed on mountain pasture and cows that were raised indoors. As the demand for cheese consumption is steadily increasing in Korea, it is necessary to study the effects of providing marketing information regarding the health conditions and rearing system of dairy cows in relation to the nutritional composition of cheese. In addition to the marketing focus on health-promoting unsaturated fatty acid composition of milk and cheese, the relationship between providing the marketing information on the raising environments of cows and the overall liking of mountain cheese were also investigated.

L. monocytogenes는 고병원성 식중독 세균으로 치즈, 식육 및 식육가공품, 훈제연어 등을 통해 식중독을 일으킨다. 현재 국내 식품공전 상 치즈에서는 L. monocytogenes에 대하여 불검출 기준을 적용하고 있으나, 이에 대한 과학적 근거가 확실하지 않고 L. monocytogenes 식중독에 대한 국민의 경각심을 일깨우기 위하여 기존에 수행된 연구들을 토대로 위해평가를 실시하였다. 그 결과, 치즈에 L. monocytogenes의 초기오염수준은 -4.0 Log CFU/g으로 확인되었다. 2018년 국민건강영양조사 결과 치즈의 섭취자 비율은 11.8%이고, 치즈 섭취량에 대한 최적확률분포는 Lognormal distribution이며 평균 32.5 g의 치즈를 섭취하는 것으로 확인되었다. 치즈 섭취로 인한 L. monocytogenes 식중독 발생 가능성은 일반군에서 평균 5.09×10-7, 민감군에서 평균 4.32×10-6로 분석되어, 민감군에서의 식중독 발생 가능성이 다소 높은 것으로 확인되었다. 식중독 발생 가능성에는 섭취자 비율이 가장 큰 영향을 미치지만 보관 및 운송 시간 또한 영향을 미치는 것으로 확인되어 유통환경에 대한 철저한 관리가 중요한 것으로 사료된다. 본 위해평가를 통하여 치즈에서의 L. monocytogenes의 기준규격을 뒷받침 할 수 있는 과학적인 데이터를 확보할 수 있었다. 향후 다양한 식품에서의 L. monocytogenes 위해평가 연구가 수행되어야 할 것으로 사료된다.

This study evaluated the risk of Clostridium perfringens (C. perfringens) foodborne illness from natural and processed cheeses. Microbial risk assessment in this study was conducted according to four steps: hazard identification, hazard characterization, exposure assessment, and risk characterization. The hazard identification of C. perfringens on cheese was identified through literature, and dose response models were utilized for hazard characterization of the pathogen. For exposure assessment, the prevalence of C. perfringens, storage temperatures, storage time, and annual amounts of cheese consumption were surveyed. Eventually, a simulation model was developed using the collected data and the simulation result was used to estimate the probability of C. perfringens foodborne illness by cheese consumption with @RISK. C. perfringens was determined to be low risk on cheese based on hazard identification, and the exponential model ($r=1.82{\times}10^{-11}$) was deemed appropriate for hazard characterization. Annual amounts of natural and processed cheese consumption were $12.40{\pm}19.43g$ and $19.46{\pm}14.39g$, respectively. Since the contamination levels of C. perfringens on natural (0.30 Log CFU/g) and processed cheeses (0.45 Log CFU/g) were below the detection limit, the initial contamination levels of natural and processed cheeses were estimated by beta distribution (${\alpha}1=1$, ${\alpha}2=91$; ${\alpha}1=1$, ${\alpha}2=309$)${\times}$uniform distribution (a = 0, b = 2; a = 0, b = 2.8) to be -2.35 and -2.73 Log CFU/g, respectively. Moreover, no growth of C. perfringens was observed for exposure assessment to simulated conditions of distribution and storage. These data were used for risk characterization by a simulation model, and the mean values of the probability of C. perfringens foodborne illness by cheese consumption per person per day for natural and processed cheeses were $9.57{\times}10^{-14}$ and $3.58{\times}10^{-14}$, respectively. These results indicate that probability of C. perfringens foodborne illness by consumption cheese is low, and it can be used to establish microbial criteria for C. perfringens on natural and processed cheeses.

국민소득의 증가와 수입자유화에 따라 치즈 소비량도 매년 증대되어 1991년 8천 5백톤에서 2001년에는 5만 3천여톤으로 10년간 6배 이상의 소비증대를 나타내었으며, 같은 기간 신선한 치즈(H.S. 0406.10.1000)의 수입량도 2톤, 3만 달러에서 2만톤, 4천 9백만 달러로 양으로는 만 배, 금액으로는 1,600여배 증가하였다. 또한, 가공 치즈에 있어서도 1991년 4,790톤에서 2001년 24,973톤으로 5.2배의 소비증가를 나타내었으나 성분규격 및 분류체계는 적절하지 못하게 규정되어 있다. 자연치즈의 경우 정의에 따라 총고형분이 유고형분과 차이가 없을 것으로 생각되며, 한 종의 연성치즈를 제외하고는 모두 규격을 만족시켰으나 유고형분 함량에 따라 '생치즈'와 '연성치즈'가 구별되지는 않았다. 따라서, CODEX의 규정을 참조하여 지방을 제외한 성분중 수분함량(MFFB)에 따라 초경질, 경질, 반경질, 연질로 구분하는 것이 치즈의 조직적 특성을 고려할 때 적절하리라 생각되며, 건물중 지방함량에 따라 60% 이상을 '고지방', 25∼60%를 '중지방', 25% 이하를 '저지방'으로 분류하는 것이 바람직하리라 생각된다. 가공치즈는 소비자의 기호에 따라 다양한 제품이 개발되고 있으며 앞으로도 더욱 소비확대가 기대되는 제품으로서, 유고형분 15∼34% 제품을 '치즈가공품'으로 분류하여 규정하는 것이 가공치즈의 개발 및 소비촉진을 위해 필요하다고 생각된다.

전해오는 전설에 의하면 인류 최초의 치즈는 양의 위를 가지고 만든 주머니에 우유를 담아 사막을 횡단하던 아라비아 상인에 의해 발견된 것으로 전해오고 있다. 기원전 9,500년경부터 메소포타미아의 비옥한 초승달 지대에 살던 농부들은 인류의 문명만큼이나 오래된 치즈라는 유산을 남기게 되었다. 우리나라 최초의 치즈는 1964년 임실성당 주임신부로 부임한 지정환 신부에 의해서 1968년 제조에 성공한 까망베르 치즈이다. 이후 지정환 신부는 1970년 모짜렐라 치즈, 1972년 체다치즈를 생산, 유통 시킴으로서 한국 치즈산업 발전의 토대를 만들었다. 이후 1980년대 후반 슬라이스 형태의 가공치즈가 출시 됨에 따라 다양한 가공치즈 제품들이 생산되기 시작하였다. 2000년대에는 웰빙 트렌드에 힘입어 유기농 치즈와 다양한 기능성 성분을 첨가한 기능성 가공치즈의 전성기를 맞이하게 된다. 국산 자연치즈(숙성치즈)는 2004년 까망베르와 브리 치즈가 출시됨으로서 본격적인 숙성치즈 시대를 열게 되었다. 최근의 치즈 소비 트렌드는 진품치즈, 강렬한 풍미, 세련된 스낵치즈 및 전통적인 방식으로 제조한 치즈를 선호하며 음식점에서 인기 있는 치즈는 모짜렐라, 파르메산, 체다, 프로볼로네 및 페타 치즈 등이다. 현재 우리나라는 수입치즈의 영향으로 자연치즈 생산량은 감소, 가공치즈 생산량은 증가 추세에 있으며 전체적인 소비량 역시 매년 증가 추세이다.
