  • The advent of the Internet and social media has given rise to a number of anti-milk articles that contain a lot of misinformation. Should milk and dairy products really not be consumed past a certain age? To answer this question, the history of milk consumption must be examined to understand the long-term benefits of milk. Historically, dairy products were among the foods served to the angels in the Old Testament of the Bible. Furthermore, dairy products were consumed even before the Bronze Age, and are defined by many food and animal scientists, and nutritionists as a complete food containing a lot of nutrients. Milk and dairy products have significantly contributed to the Korean and Japanese people's current body structures; this is evident in the fact that they are taller than their ancestors, primarily due to the increased consumption of milk and dairy products following industrialization. The average height of Koreans rose drastically in the 1960s, after milk consumption increased as a result of the dairy promotion policy. This article seeks to help understand milk by looking into the content published by a life insurance company in 1927.

  • The purpose of this study was to determine if Theory of Planned Behavior (TPB) variables predict soy milk intake in a sample of WIC participants in 2 Illinois counties (n = 380). A cross-sectional survey was used, which examined soy foods intake, behavioral beliefs, subjective norms, motivation, and intention. Soy product intake was low at both sites, and many participants (40%) did not know that soy milk was WIC approved. Most (> 70%) wanted to comply with their health care providers, but didn't know their opinions about soy milk (50-66%). Intention was significantly correlated with intake (0.507, P ${\leq}$ 0.01; 0.308, P ${\leq}$ 0.05). Environmental beliefs (0.282 and 0.410, P ${\leq}$ 0.01) and expectancy beliefs (0.490 and 0.636, P ${\leq}$ 0.01) were correlated with intention. At site 1, 30% of the variance in intention to consume soy milk was explained by expectancy beliefs and subjective norm beliefs (P < 0.0001); at site 2, 40% of the variance in intention was explained by expectancy beliefs. The TPB variables of expectancy beliefs predicted intention to consume soy milk in WIC participants. Therefore, knowing more about the health benefits of soy and how to cook with soy milk would increase WIC participants' intention to consume soy milk. Positive messages about soy milk from health care providers could influence intake.

  • Immunoblotting and competitive indirect enzyme-liked immunosorbent assay(Ci-ELISA) was used for detection of ${\beta}$-lactoglobulin(BLG) in dairy products, such as milk, dried milk and fermented milk. In immunoblotting, human IgE weakly recognized proteins of fermented milk, but still responded to dried milk even though become weak. Rabbit polyclonal antibody to BLG, used as a model of antigen, and milk allergic patients' IgE was used in the ELISA. Reactivities of Abs were the highest in market milk. BLG in fermented milk was detected in a low content. This result indicates the fermented milk have the lowest BLG content and could be used as hypo-allergenic food for milk-allergic individual.

  • Many studies have shown that advanced glycation end-products (AGEs) and glycation adducts are significantly linked to aging and disease. Particularly, the level of glycation in human milk is important because the AGE intake is closely related to AGE levels in infants. In this study, we used human milk samples obtained from four primiparae and four multiparae. We isolated proteins using acetone and trichloroacetic acid (TCA) precipitation. A total of 67 glycated proteins and 122 glycated peptides was quantified; among them, 19 glycated peptides were differentially expressed. We confirmed that the degree of glycation differed according to fertility. The study provides a foundation for using proteomics to evaluate the mother's milk quality and link between maternal health and human milk quality.

  • This study was conducted to investigate the relationship among the current status of calcium intake from milk and milk products, physical growth and bone mineral density in 664 male and female middle school and high school students aged 15-17 years. In the study, the current status of calcium intake from milk and milk products was analyzed, and the height, body composition, and bone mineral density of the right heel bone (calcaneus) were measured. The daily calcium intake of milk and milk products was calculated as the 'dairy equivalent of calcium', which is the calcium content in 200 mL of white milk. The cutoffs of tertiles of the dairy equivalent of calcium were calculated and then the subjects were categorized into 3 groups according to the tertiles, Q1 group (lower intake group), Q2 group (middle intake group) and Q3 group (upper intake group). The daily calcium intake of milk and milk products in Q1, Q2 and Q3 groups was 16.2 mg, 99.7 mg, and 284.0 mg, respectively, and the ratio of milk and milk product consumption to the daily total calcium intake was 5.4%, 27.4%, and 49.7%, respectively. The ratio of total calcium intake to the daily recommended intake in study subjects was 30.5% in Q1, 42.3% in Q2, and 60.7% in Q3, with significant differences (P < 0.05). Height, body weight, BMI, and % of body fat in three tertile groups (Q1, Q2 and Q3) were not significantly different. However, the T scores for bone mineral density in female students in three tertile groups (Q1, Q2 and Q3) was significantly different (P < 0.05). The study showed that the intake of milk and milk products in adolescents, particularly in girls, can improve the bone mineral density without increasing body weight, and thus confirmed that milk intake is important in adolescence.

  • Consumers have become increasingly more aware of food safety issues, as a consequence of s number of food scandals. Most of these scandals have been related to livestock products. However, most consumers still believe that it is possible to produce safe food at low prices, while a small group of consumers is willing to pay a price surplus for special quality. Organic standards, especially for livestock products, have very few definitions of process quality, and even fewer of these definitions that influence product quality. This paper work to organic milk production and marketing trends in Korea.

  • Objective : Tarag refers to fermented milk, which has been recognized as daily food of summer in nomadic culture. Also, tarag is cleary defined as a fermented milk product in most of east Asian medical texts. When it comes to tarag-juk described in Korean medical texts, however, there is no definite distinction between milk porridge and tarag-juk. This paper is aimed at finding out whether tarag was merely meaning milk in Joseon. Method : Historical documents of related historical stage, Tibetan and East Asian medical texts, and some cookbooks are mainly consulted, as well as other sources that contains the perception of tarag in Korean history. Result : Tarag is documented as fermented milk in the medical texts of herbs, while tarag-juk is defined as milk porridge in some medical texts in Korea. In one of the Mongolian-Korean dictionary of 18C, milk tea is explained as tarag tea. Conclusion : Although there is not much evidence to back up this conclusion with satisfaction, it would not be to much to say that conception of tarag met some changes from yogurt to boiled milk during Joseon dynasty.

  • There has been a successful re-entry in the form of infant foods and as a product concept of "well-being" milk by feeding goat natural medicinal plants in high mountain lands and goats eating natural feeds. Typical composition of cow's milk and goat's milk are not significantly differ in major nutritional constituents. However, the noticeable differences between milks of the bovine and caprine species concern in the dimensions of the micelles, in casein composition, in size of the micelles and in the mineral charge of the micelle, but the ratio Ca/Pi in the micelle is very close for the two species The potential market in Korea could be expected to expand by keeping its freshness and nutritional benefits. The supply of goat milk products all year around is also an important to the consumers. In order to increase its market scale of goat milk, product manufacturers need extensive advertising promotion. Domestically, goat milk is currently manufactured at small scale dairy goat milk companies and consumed mainly in the form of fresh or fermented goat milk, while imported goat milk powder is used to produce infant goat milk formula by major dairy companies. Decreasing the unpleasant goaty flavour for the Korean consumers would be essential for the researchers who work for dairy science and technology.

  • In Korea, there are a couple of risk assessment organizations: The Animal Plant and Fisheries Quarantine and Inspection Agency(QIA) and the Korea Food and Drug Administration (KFDA). The major food laws include the Food Sanitation Act (FSA), the Livestock Product Processing Act (LPPA), and the Agricultural Products Quality Control Act (APQCA). Milk and dairy products are mostly controlled by the Food Sanitation Act and the Livestock Product Processing Act. This study was carried out to estimate the current standard methods of foodborne pathogens for dairy products, comparing the Livestock Products Processing Act with the Food Sanitation Act. The standard methods of foodborne pathogens for dairy products are composed by growth culture, isolation culture, and identification, however, standard methods of QIA and KFDA are different at the using of medium and inspection stage. Therefore, consolidation of risk management and risk assessment methods are regarded important to provide safe dairy products to consumer.

  • A duplex PCR technique was applied for specific identification of cow and goat milk in milk products by using primers targeting the mitochondrial 12S rRNA gene. Duplex PCR using primers specific for cow and goat generated specific fragments of 223bp and 326bp from cow and goat milk DNA, respectively. Duplex PCR was applied to 15 milk products purchased from the market to verify label statements. The labeling statements of four market milk products, three yoghurt products, and one whole milk powder product were confirmed in the duplex PCR. The labeling statements of five of seven infant milk powder products were also confirmed by duplex PCR but the other two products were shown to be contaminated with either cow or goat milk. The proposed duplex PCR provides a rapid and sensitive approach to detection of as little as 0.1% cow milk in goat milk and one-step detection of cow or goat milk in milk products.
