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.

Listeria monocytogenes is a highly pathogenic gram-positive bacterium that is easily isolated from cheese, meat, processed meat products, and smoked salmon. A zero-tolerance (n=5, c=0, m=0/25 g) criteria has been applied for L. monocytogenes in cheese meaning that L. monocytogenes must not be detected in any 25 g of samples. However, there was a lack of scientific information behind this criteria. Therefore, in this study, we conducted a risk assessment based on literature reviews to provide scientific information supporting the baseline and to raise public awareness of L. monocytogenes foodborne illness. Quantitative risk assessment of L. monocytogenes for cheese was conducted using the following steps: exposure assessment, hazard characterization, and risk characterization. As a result, the initial contamination level of L. monocytogenes was -4.0 Log CFU/g in cheese. The consumption frequency of cheese was 11.8%, and the appropriate probability distribution for amount of cheese consumed was a Lognormal distribution with an average of 32.5 g. In conclusion, the mean of probabilities of foodborne illness caused by the consumption of cheese was 5.09×10-7 in the healthy population and 4.32×10-6 in the susceptible population. Consumption frequency has the biggest effect on the probability of foodborne illness, but storage and transportation times have also been found to affect the probability of foodborne illness; thus, management of the distribution environment should be considered important. Through this risk assessment, scientific data to support the criteria for L. monocytogenes in cheese could be obtained. In addition, we recommend that further risk assessment studies of L. monocytogenes in various foods be conducted in the future.

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.

Cheese consumption in Korea has continuously increased far the last decades by industrialization and globalization. In addition, import of fresh cheese has increased from 2 tons, and 30 thousand dollars in 1991 to 20 thousand tons, and 49 million dollars in 2001. However, Korea standard for cheese differs from CODEX, and is not consistent. To investigate more proper standards for cheese, 20 natural cheeses and 17 process cheeses were obtained from market and analysed. All the cheeses except 1 soft cheese met the standard, but 'unripened cheese' was not different from 'soft cheese' in milk solid content. Natural cheese firmness showed exponential inverse relationship(R=0.8226) to moisture on a fat-free basis(MFFB) which is used for the natural cheese standard in CODEX. Therefore, it was thought appropriate to refer to CODEX standard for using textural terminology in Korea standard for natural cheese. For process cheese, milk solid cant be estimated by the analysis, and there are no merits and penalties by the classification. It was thought proper to classify the process cheese by types, such as 'Powder', 'Slice', 'Spread', and 'Portion'. Rule for 15∼34% milk solid content of products should be prepared in standard for animal products as 'Process cheese products' for the promotion of development and consumption of cheese.

Cheesemaking is believed to have been first practiced in prehistoric times, about 9,500 years ago, in the area around the Fertile Crescent of Mesopotamia and they left legacy in the name of cheese. Father Chi Chong-Hwan(Didier Serstevens) started for his provost in Imsil Catholic church in 1964. In 1968, cheese was first produced Camembert in Korea by Father Chi Chong-hwan, and then made Mozzarella in 1970, Cheddar in 1972. Father Chi lay the foundation of a cheese industry in Korea. The processed cheese market was highly grown after putting on the market of sliced cheese in the late 1980s, and the various products that complied with wellbeing trends such as organic and high functional cheese produced in the 2000s. The natural cheese opens up a new domestic market after producing Camembert and Brie cheese in the end of 2004. At present, major trends in cheese are authenticity, bold flavor, snack sophistication and tradition. Mozzarella, Parmesan, Cheddar, Provolone, Feta cheese still top in foodservice. In Korea, production of natural cheese is decreasing by the influence of the imported cheese. Production of processed cheese is increasing and total consumption of cheese is also increasing year by year.
