This study was carried out in order to facilitate the consumption of milk which tend to decrease in recent years and to improve the school milk program. The survey by means of prepared questionnaire was conducted to investigate a perception and satisfaction of school milk program, and milk intake at home and school with elementary, middle, and high school students. Most of the subjects thought drinking milk is important for their health but only 50.2% of them were actually drinking milk everyday. In particular, the frequency of consuming milk at home was significantly lower in students being provided with school milk program than the students without school milk program. Most of the students commonly drunk plain milk rather than flavored milk, however actually they preferred flavored milk to plain milk. The frequency of consuming milk and the degree of satisfaction for milk being served in the school milk program was lowered. The major reason of disliking milk being served in school milk program was ‘poor taste’. And to promote milk consumption in school milk program, the subjects anticipated the serving of various milk and dairy products, flavored milk and yogurt etc. Thus, it was suggested that to improve the school milk program and promote milk consumption among the students, serving various products that can satisfy their preferences and demands and the proper food guide and education on nutrition are called for.

The purpose of this study was to investigate the nutrition knowledge, perception, and intake frequency of milk and milk products among middle school students as well as provide the basic data needed for increasing milk and milk product consumption. To achieve the purpose of this study, a survey with 385 students of four middle schools located in Chuncheon was conducted. The level of nutrition knowledge of milk and milk products in females was slightly higher than that in males (p<0.01). Flavored milk and ice cream were preferred the most in each category, and 'taste' influenced the selection of milk and milk products the most. The intake frequency of whole milk was the highest, and that of flavored milk was lowest among various milks. Ice cream showed the highest intake frequency while cheese showed the lowest among milk products. Male students showed higher intake frequency of milk and milk products. Groups having high level of nutrition knowledge showed the highest intake of whole milk, whereas groups having a low level of nutrition knowledge preferred processed milk, low fat or non-fat milk, and cheese the lowest.

Accuracy of dietary assessment depends on correct estimation of quantity as well as correct data on composition of the products. Milk and soymilk were considered quite homogeneous in items of package size and composition. One serving size of fluid milk and soymilk is considered 200 mL but there are products with different amounts on the market. This study was conducted to investigate variations of amounts and composition of fluid milk and soymilk products of one portion siz on Korean market. Twenty-nine milk products were purchased and categorized into 8 groups-regular, low-fat, skim, chocolate, strawberry-flavored, banana-flavored, and black soybean-added. Sixteen fluid soymilk products were purchased and categorized into 4 groups-regular, infant, black sesame or black soybean added and others. Actual volume of each product was measured by mass cylinder and compositions of major nutrients on the package were compared to the values in the most widely used nutrient DB in Korea. Amounts of milk specified on the package of purchased products were 182.3-318.5 ml, the largest being banana-flavored milk. Amounts of soy milk were 184.3-240.5 mL, the largest being regular soymilk. Measured amount of each products were close to the amount on the package (<5%). Contents of macronutrients on the package were different from the food composition table in several products. The amounts of calcium varied greatly among the products due to the popularity of adding calcium to milk and soymilk products recently. These variations in the amount and contents of major nutrients in milk and soymilk products can lead to considerable error to the results of dietary assessment unless the amount and the composition of each product are regularly updated in the food composition table whenever the new products are introduced in the market.

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.

This study was designed to examine the level of milk consumption and perception of the school milk programs among elementary, middle and high school students, which provides the information to improve the school milk program. Using a self-administered questionnaire survey, the data collected from 1,725 students nationwide were analyzed. The results showed that whole milk was the type of milk most frequently drunk by the students, although flavored milk and yogurt products were also highly preferred. When asked whether they wanted the school milk program or not, approximately 30% of the students in the schools presently participating in the school milk program and 50% of the students in the schools not participating the school milk program answered "yes". However, all of the respondents preferred to have a choice for the school milk program. The elementary school students showed a higher level of satisfaction with the school milk program than the middle and high school students. Especially, the level of satisfaction with the taste and flavor of the milk was the lowest among the various satisfaction items. However, the students were reported to believe that milk is highly nutritious and good for their health in the present study. Our results suggest that providing a choice of dairy products would improve the students' satisfaction with the school milk program, and that continuous education about the benefits of drinking milk would also encourage them to participate in the school milk program.
