  • Cheese is a nutritious food with various balanced nutrients, such as proteins, peptides, amino acids, fats, fatty acids, vitamins and minerals. Domestic cheese varieties and quality need to be improved to prevent imported cheese. To develop those cheeses, search for previous works and research for new products are needed. In cheese ripening of hard cheese, such as Cheddar or Parmesan cheese, is ripened for 2 to 24 months at 2 to 16$^{\circ}C$ to develop desired cheese flavor and body characteristics. Long time with low temperature to ripen the cheese requires high expenses. So accelerated cheese ripening is a good potential for saving in industry. Methods for acceleration of cheese ripening are temperature control, addition of bacteria or enzymes. To develop the functionality of cheese, addition of microencapsulated various probiotics and nutrients, such as iron, removal of cholesterol by crosslinked ${\beta}$-cyclodextrin, lowering blood cholesterol and serum glucose by nanopowdered functional materials et al. are necessary. Therefore, this review focused on the functionality of cheese, such as the acceleration of cheese ripening, microencapsulated probiotics and iron, and cholesterol removal.

  • 현재 한국에서 소비되는 치즈는 수입 의존도가 높은 편이며, Mozzarella 치즈의 경우 10% 미만이 한국에서 제조되나, 가격 경쟁력에서 수입제품에 비해 크게 불리한 입장이다. 무엇보다 높은 원유가격과 Mozzarella 치즈의 급격한 소비 증가는 적당한 공급가를 일정하게 공급하기에 많은 어려움이 있는 실정이다 따라서 대두단백을 이용한 Mozzarella cheese analogue 제품 제조가 요구되어 다양하게 생산 및 제조되고 있다. 대두단백은 유제품성분의 한정적인 공급과 caseinate의 높은 가격 때문에 Mozzarealla cheese analogue 제조에 많이 사용되고 있다. Casein-based Mozzarella cheese analogue보다 soy-based Mozzarella cheese analogue가 오랜 기간 동안의 안정성과 실질적인 가격우위는 높은 경쟁 잠재력이 있다. 또한 Mozzarella cheese analogue는 저수분 Mozzarealla 치즈처럼 풍미의 문제점은 없지만, 몸체가 용해될 때 신축이 잘 되지 않고, 과도한 caseinate, 대두단백 특유의 콩비린내(beany flavor), 이상한 풍미, 갈변화 등의 문제 등이 존재하는 것이 사실이지만, 대두를 이용한 다양한 cheese analogue는 기존의 자연치즈에 비하여 가격이 저렴할 뿐만 아니라, 소비자의 다양한 수요 요구를 충족할 수 있는 장점이 있다. 더 나아가서 콩의 부가가치 향상과 국민영양 개선의 측면에서도 효과가 많은 것으로 사료된다. 무엇보다 cheese analogue의 제조는 수입 억제 효과와 수출 증진 효과에도 크게 기여할 것으로 사료된다. 따라서 cheese analogue 제조에 많은 관심과 지속적인 연구가 진행되어야 할 것이다.

  • This study was conducted in order to evaluate the quality characteristics of Gouda cheeses supplemented with fruit liquor (Prunusmume or Cornus officinalis). Fruit liquor was supplemented to Gouda cheeses during preparation. Changes in chemical composition, lactic acid bacterial population, pH, water-soluble nitrogen, sensory characteristics, and proteolysis were monitored in the prepared ripened cheese. The electrophoresis patterns of cheese proteins, fruit liquor functional component concentrations, and the flavonoid content of the cheeses were also determined. The addition of fruit liquor did not affect (p> 0.05) the appearance or sensory characteristics of the cheeses. Higher amounts of crude ash, mineral, and flavonoids (p< 0.05) were observed in the liquor supplemented cheese than in the control cheese. Findings from this study suggest that wine supplemented Gouda could provide additional nutrients while maintaining flavor and quality.

  • The present study aimed to investigate the microbial diversity in Gouda cheese within the four months of ripening, via next-generation sequencing (NGS). Lactococcus (96.03%), and Leuconostoc (3.83%), used as starter cultures, constituted the majority of bacteria upon 454 pyrosequencing based on 16S rDNA sequences. However, no drastic differences were observed among other populations between the center and the surface portions of Gouda cheese during ripening. Although the proportion of subdominant species was <1%, slight differences in bacterial populations were observed in both the center and the surface portions. Taken together, our results suggest that environmental and processing variables of cheese manufacturing including pasteurization, starter, ripening conditions are important factors influencing the bacterial diversity in cheese and they can be used to alter nutrient profiles and metabolism and the flavor during ripening.

  • EMC는 치즈와 유사한 효소작용은 거치게 되지만 치즈에 비하여 더 많은 효소작용에 의하여 더욱 강력한 풍미를 생산하게 된다. 이러한 우수한 EMC의 개발을 위하여 적합한 효소를 찾아내는 것은 중요한 과제이다. 심지어 동일한 PGE도 송아지의 것이 어린 염소나 어린 양의 것에 비하여 더 부드러운 맛을 생산할 수 있다. 특히 체다치즈의 풍미를 위하여는 미생물효소보다 동물성 esterase나 peptides가 유리한 것으로 알려지고 있으며, 체다치즈나 스위스치즈의 경우 비단 백태 질소화합물의 양도 EMC가 치즈에 비하여 3배 가까이 많았다. 체다 EMC의 성분 비율에서도 유리지방산에는 butyric acid, myristic acid, palmitic acid와 oleic acid가 많았고, 유리 아미노산에는 glutamic acid, valine, leucine과 lysine이 많은 것으로 나타났다.

  • Molds cause severe cheese deterioration, even though some white and blue molds are used for the manufacture of Camembert and Blue cheese, respectively. The species of Geotrichum, Moniliella, Aspergillus, Penicillium, Mucor, Fusarium, Phoma, and Cladosporium are the main fungi that affect contamination during cheese ripening. Once deteriorated by fungal spoilage, cheese becomes toxic and inedible. Fungal deterioration of cheese decreases the nutritional value, flavor profiles, physicochemical and organoleptic properties, and increases toxicity and infectious disease. Fungal contamination during cheese ripening is highly damaging to cheese production in Korean farmstead milk processing companies. Therefore, these companies hesitate to develop natural and ripened cheese varieties. This article discusses the recent and ongoing developments in the removal techniques of fungal contamination during cheese ripening. There are 2 categories of antifungal agents: chemical and natural. Major chemical agents are preservatives (propionic acid, sodium propionate, and calcium propionate) and ethanol. Among the natural agents, grapefruit seed extract, phytoncide, essential oils, and garlic have been investigated as natural antifungal agents. Additionally, some studies have shown that antibiotics such as natamycin and Delvocid$^{(R)}$, have antifungal activities for cheese contaminated with fungi. Microbial resources such as probiotic lactic acid bacteria, Propionibacterium, lactic acid bacteria from Kimchi, and bacteriocin are well known as antifungal agents. In addition, ozonization treatment has been reported to inhibit the growth activity of cheese-contaminating fungi.

  • Milk and milk products, especially the cow's milk and cheese, have been used since the ancient time. Because they contains almost all kinds of nutrients that are necessary for human beings except for iron, n-3 fatty acid, and vitamin C. Milk is an excellent dietary source of protein, calcium and phosphorus. The biological value of milk protein is as high as those of red meat and eggs. So cheese, a food processed from concentrated milk protein, is highly recommended food for the patient of diabetes mellitus. Because the major form of milk lipids is n-6 fatty acid, milk and milk products may not be a good food for the patients of cardiovascular disease. But the nutritional quality of milk lipids cannot be inferior to those of margarine, fish oil, and vegetable oil. Milk has been produced commercially since 1936 in Korea. The most popular milk product is a drink milk now in Korea. But according to the change of dietary pattern the consumption of yoghurt and cheese has been enormously increased during the last 20 years. As the soy sauce, tofu, and soy been paste have been the fundamental seasoning and source of protein in Korea, milk and cheese have consisted the essential flavor of western cuisine. But the basic idea for the usage of protein, peptides, and amino acids are the same. We found that milk and milk products can be nicely added in many Korean dishes such as Juk, Mandoo, Jeon, and Bindeatuk for the diversity of traditional flavor.

  • This study was conducted to develop a novel cheese tofu hybrid product by increasing the calcium content of cheese, an animal protein source, and tofu, a vegetable protein source. Both pH and moisture were lower in the cheese tofu hybrid than those values in the control group (6.03% and 72%, respectively). Protein and fat were slightly higher than in the control (15.43% and 9.91%, respectively). Total bacteria count increased at the end of the product's shelf life, but did not affect its texture. The cheese tofu hybrid displayed stronger a) red, and b) yellow coloration than the control, and its lightness (L) was lower than that of the control. The cheese tofu hybrid possessed high hardness, and displayed high values for gumminess and brittleness. Sensory evaluation by a specialized agency examined consumer preferences, purchase intentions, strengths, and weaknesses of the developed product line. A panel of 30 female volunteers in their 20s and 40s recorded an overall preference for cheese tofu of 5.40 points, fairly good. Cheese tofu was found to be better than the control tofu, with appealing differences in appearance, color, nutty aroma, chewiness, and cheese flavor.
