In 1967, cheese was first produced with small scale of mozzarella cheese in Korea. The processed cheese market was highly grown after putting on the market of sliced cheese in the late 1980's, and the various products that complied with well-being trends such as organic and high functional cheese have been produced in the 2000's. The natural cheese opens up a new domestic market after producing camembert and brie cheese in the end of 2004. At present. the cheese market is expanded with differentiated products such as high value added and high functional cheese. The size of domestic cheese market remains about 200 billion won, but it is expected to go over a trillion won on account of growing preference of natural cheese with well-being trends. To promote domestic cheese industry, differentiation policy of raw milk price for cheese, diversification of cheese products, financial support to farm-made cheese industry and automation and processing development to improve productivity should be taken into account in the future in Korea.

To determine changes in nitrogen contents and optimal rates as N fertilizer, we investigated nitrogen characteristics in the slurry in the respond to the application of 0, 0.5, and 1 g of ferrous sulfate or alum /25g of dairy slurry. Additions of ferrous sulfate or alum increase total nitrogen, inorganic nitrogen, available nitrogen, and predicted available nitrogen contents in dairy slurry, resulting in reduction in pH. The best results were found in the treatment with 0.5 g of ferrous sulfate or alum /25 g of dairy slurry. In conclusion, the use of ferrous sulfate or alum as on-farm amendment to dairy slurry should be represented an alternative to improve N in dairy slurry.

This study investigated the awareness and consumption behavior of 118 vegetarians and omnivores toward plant-based dairy alternatives. The preference and choice attribute questionnaires were compared. Significant differences were obtained between the two groups when considering the purchase experience, preference, and selection attributes of plant-based dairy alternatives. Vegetarians had more experience purchasing plant-based dairy alternative products. In both groups, environmental and animal protection were the major factors that influenced the highest response rate for purchasing plant-based dairy alternatives. The preference score of vegetarians for plant-based dairy alternative products was high, indicating that vegetarianism had a significant effect on their preference for plant-based dairy alternative products. Analysis of selection attributes revealed that price, product weight, appearance, and manufacturer were considered important by vegetarians, whereas nutritional components and labeling, manufacturing environment, composition of ingredients, and taste and texture were considered more important by the omnivores. Results of this study can be used as basic data for the future development of the fast-growing industry producing plant-based dairy alternative products.

본 연구는 일반적으로 사용되고 있는 vitamin C 분석방법인 2,4-dinitrophenylhydrazine(DNP), indophenol, 그리고 HPLC법을 이용하여 시판중인 다양한 제품을 이용하여 보존조건($10^{\circ}C,\;20^{\circ}C$)에 따른 vitamin C 함량을 세 가지 방법으로 비교 검토함으로서 가장 이상적인 분석방법을 조사하였다. $10^{\circ}C$ 보존시 요쿠르트 A 제품에서의 vitamin C 변화 추세를 살펴보면, DNP법은 초기와 말기 TAA 함량이 각자 26.7과 22.8mg/100mL로 측정되었으나, 저장 3일째와 10일째에 오히려 증가하는 현상을 보였으며, 또만 indophenol법은 초기와 말기에 각각 28.6과 9.5mg/100mL로, HPLC법은 30.5와 14.6mg/100mL로 확인되었다. 그리고 본 실험에서는 indophenol법과 HPLC법은 일정한 감소 추세를 보였다. 따라서, 가장 이상적인 vitamin C 분석 방법은 HPLC법이며, 저장 초기에 간단하게 vitamin C 함량을 측정할 경우에는 indophenol법을 이용하여도 신뢰할 수 있는 결과를 얻을 수 있는 것으로 사료된다.

Milk pasteurization is used to destroy harmful bacteria present in the raw milk for improvement of the keeping quality of dairy products. It is generally carried out in dairy industries as the heating process of raw milk in properly designed and operated equipment to a specific temperature for a specified a specified period. However, thermal processing may cause quality changes in milk as well as significant nutritional losses. Hence, many researchers have started work to design alternative strategies to produce safer foods with minimal thermal treatments for pasteurization. Therefore, the present paper shows the current status of commercial pasteurization system of dairy products in korean industry and the research efforts carried out by researchers on novel milk pasteurization system that could be an alternative to traditional thermal processes for maintaining the freshness of dairy products.

Dairy goat production continues to be a socially, economically and culturally important part of the livestock industry in North, Central and South America and the Caribbean islands. Goat milk, cheese and other dairy products offer consumers food products with nutritional, health and environmental benefits. In North America, Mexico produces the greatest volume of goat milk, but most is for family or local consumption that is typical of a mixed farming system adopted by subsistence farmers in dry areas. The United States is not yet a large global goat milk producer, but the sector has expanded rapidly, with dairy goat numbers doubling between 1997 and 2012. The number of dairy goats has also increased dramatically in Canada. Commercial farms are increasingly important, driven by rising demand for good quality and locally sourced goat cheese. In South America, Brazil has the most developed dairy goat industry that includes government assistance to small-scale producers and low-income households. As of 2017, FAO identified Haiti, Peru, Jamaica, and Bolivia as having important goat milk production in the Western Hemisphere. For subsistence goat producers in the Americas on marginal land without prior history of chemical usage, organic dairy goat production can be a viable alternative for income generation, with sufficient transportation, sanitation and marketing initiatives. Production efficiency, greenhouse gas emission, waste disposal, and animal welfare are important challenges for dairy goat producers in the Americas.

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.
