This study was conducted to investigate the consumption of milk, along with satisfaction for improvement of the school milk program in middle school. The subjects were 447 middle school students(265 male, 182 female) in the Gyeonggi area, whowere asked to fill out the questionnaire. The collected data were analyzed by a SAS package. The results showed that 53.2% of the subjects were participating in the school milk program. Regarding the frequency of milk consumption, 77.7% of students reported daily milk consumption and 65.3% of students reported they drank milk when it was available. 56.8% of the students responded that they were satisfied with the school milk program. Male students not participating in the school milk program cited the reason as "eating at home", while non-participating female students cited the reason as "tasteless". When asked whether they accepted or rejected the school milk program, male students(97.7%) and female students(97.8%) answered "it should be executed". To improve the school milk program, most of the students(72.2%) stated that "it should be selected among flavored milk(strawberry, banana, chocolate, black bean, and husked rice milk) instead of white milk". Therefore, in order to increase the intake of milk, the students should develop the habit of drinking milk to gain the attention of parents. Also, schools should attempt to help through offering proper dietary education.

This study examined the satisfaction of a school milk program as well as the preference of school milk and flavored milk. The subjects of this study were $4^{th}$
, $5^{th}$ and $6^{th}$ grade students in 4 different elementary schools, who were attending the school milk program in Ulsan. The survey was conducted from April 10, 2009 to April 30, 2009. Of the 403 questionnaires distributed, 347 responded and analyzed (usage rate: 86%). The results were as follows. Of the 347 respondents, 53.9% were boys and 46.1% were girls. 34%, 31.1% and 34.9% of the students were $4^{th}$, $5^{th}$ and $6^{th}$ graders, respectively. Second, 80.1% of the students reported 'have milk everyday', and 89.9% of the students reported 'have milk as it is'. Third, the overall satisfaction with the school milk program was 3.32 based on a 5-point likert scale, the 'guidance of nutrition teachers and class teacher' was 3.21 and 'taste of school milk' was 3.37. There were significant positive correlations between the school milk satisfaction variables and overall satisfaction (p<0.01). Fourth, the preference for school milk was 3.33. The preference for flavored-milk were 3.63 (coffee milk), 4.44 (chocolate milk), 4.16 (strawberry milk), 4.26 (banana milk) and 3.53 (black bean milk). Fifth, to improve the school milk program, 85.9% of students wanted a provision for flavored milk. In conclusion, schools need to find a way to increase the satisfaction of the school milk program and the preference of school milk to increase the milk intake of students. Nutrition education for students and parents should be conducted systematically and choices for various kinds of milk and milk products should be given to the students.
This study was performed to investigate the relationship between milk and milk product consumption and dietary nutrient intake among Korean adolescents. Questionnaire survey and 3-day diet survey using the food record method were completed by a total of 664 subjects. Subjects were divided into three groups, Q1 (low group), Q2 (middle group), and Q3 (high group), according to dairy equivalent of calcium. Dairy equivalent of calcium was determined by the amount of calcium eaten from milk and milk products by individual subjects. As a result, the ratio of school milk service was higher in Q3 (P<0.001). The most frequent answer about the reason for consuming milk and milk products was 'to be taller' followed by 'good taste' and 'health promotion'. Preference for all types of milk such as white-, enriched-, and flavored-milk was higher in Q3 followed by Q2>Q1 (P<0.05). Ratio of mean daily dietary nutrient intakes of dietary fiber, vitamin C, folate, and calcium to RNI was lower than 2/3 for all of the groups. These mean daily dietary nutrient intakes were significantly higher in Q3 (P<0.05), and in particular, mean daily dietary calcium intake, which was the lowest nutrient consumed by Korean adolescents, was also the highest in Q3 followed by Q2>Q1 (P<0.05). The above results suggest that the school milk program is very helpful in encouraging adolescents to consume milk and milk products and consequently ensure their optimal nutrition. Therefore, we should try to encourage adolescents to participate in the school milk program more actively through nutritional education and government policy.

Acid dairy drinks(ADD) are a worldwide product existing in many variations: fruit milk drinks, yogurt drinks, soy milk, butter milk, whey drinks and kefir etc. These drinks are marketed with different shelf lives depending on processing: -Short shelf life(maximum 3 weeks, cold storage) - Long shelf life(2 to 9 months, pasteurized, sterilized or retorted) Acidic protein drinks tend to a separation or destabilization process in the absence of stabilizing system during the shelf life of the ADD. A phase separation results in sedimentation of large particles at the bottom of the package and/or the formation of a serum layer at the top(whey off). These beverages are usually composed of an acid dairy phase (fermented base)or a natural base(milk, soymilk etc.)with an acidic medium (fruit phase: pulp, fruit concentrate etc.) which can be flavored. Sugar and stabilizers are added. It has been proved since the late 1950's that adding high methoxy pectin (HM pectin)to acid milk drinks is the best way to prevent the formation of a sediment and/or the whey off. In this presentation, we explain about stabilization mechanism of ADD induced by pectin. Applications and market trend of ADD in Asia and Europe are explained.

Purpose: This study examined the yearly trend of milk consumption and the nutritional status of subjects aged 6-18 years using the 2007-2015 Korea National Health and Nutrition Examination Survey data. Methods: Milk and dairy products were classified into plain milk, flavored milk, and dairy products (ice cream, milkshakes, cheese, and yogurt, etc.). This study compared the milk and dairy products intakes, some nutrients intakes and percent of dietary reference intakes for Koreans in the milk intake and non-milk intake groups. Results: Plain milk intake decreased with year (male, p = 0.0199; female, p < 0.0001; elementary school, p = 0.0013; high school, p = 0.0061), whereas flavored milk and dairy products intake in these subjects increased with year. In all subjects, 49.9% of subjects did not drink milk at all. The intakes of energy, protein, fat, calcium, phosphorus, and riboflavin in the milk intake group were significantly higher than those in the non-milk intake group, even after adjusting for covariates (p < 0.05). The odds ratio of the prevalence of nutritional deficiency in the non-milk intake group was 3.2 times higher than that of the milk intake group (p < 0.001), even after adjusting for covariates. The odds ratio for the prevalence of excess intake of the energy/fat was not significant with milk intake. Conclusion: The prevalence of milk intake decreased every year in the subjects. Calcium deficiency and nutritional deficiency were very high in the non-milk intake group. Efforts should be made to improve the calcium status in children and adolescents by strengthening nutrition education about the importance of milk intake.
This study was performed to investigate the frequency of dairy beverage consumption and factors which affect the dairy beverage consumption of women. The subjects were 1,012 females living in Seoul. They preferred milk, yakult. flavored milk, liquid yogurt, semi-solid yogurt, and low fat milk in order of frequency. The consumption of the dairy beverage was not related to season. The respondents knew that the dairy beverages were nutritious and good for their health. More than fifty percent of them answered that dairy beverages tasted good. The consumption of milk and yakult were related with their occupation, habitual aspect, and practical factors. The consumption of liquid yogurt was affected by their family income, habitual aspect, practical factors and familarity with that beverage. The consumption of semi-solid yogurt was affected by their family income, health status, habitual aspect, and practical factors. The consumption of most beverages were affected by the recognition of those beverages rather than by socio-demographic factors. In order to enough drink dairy beverage, nutritional education messages should encourage consumption of dairy beverages. Policies that make students access dairy beverages at school should be promoted.
The global consumption of fructose in the form of high-fructose corn syrup (HFCS) has increased considerably over the past several decades. The current intake of HFCS exceeds that of other major caloric sweeteners such as sucrose. Fructose has potentially adverse effects on human metabolism. Therefore, the objective of this study was to analyze the monosaccharide contents of 13 sweetened milk-based beverages by using high-performance liquid chromatography (HPLC). The total monosaccharide (fructose and glucose) contents of various sweetened milk-based beverages ranged from 0.60 g/100 mL (cheese) to 26.03 g/100 mL (maple caramel snack), while milk showed only 0 g/100 mL monosaccharides. The fructose-to-glucose ratio of various popular sweetened milk-based beverages ranged from not-detected (ND) to 2.24 g/100 mL, but the content of glucose was higher than that of fructose in only three samples, namely, strawberry flavored milk, shrimp chips, and maple caramel snack. The analyzed results revealed important basic information about monosaccharides in various milk-based sweetened beverages, presenting ideas for future fructose research.

The purpose of this study was to analyze the amount of sugar from the afternoon snack menu of childcare facilities in Gyeongsangbuk-do. The amount of sugar was analyzed for afternoon snacks provided by childcare facilities between March and April 2016. The snacks provided were the same for processed and non-processed foods at 50.0% respectively. White milk accounted for the largest portion with 26.4%, followed by fruits with 19.9% and grains (sweet potatoes, rice cakes, etc.). It has been confirmed that the larger the facility, the lower the frequency of provision of non-processed foods, and the higher the provision of processed foods (p<0.05). Snacks served as non-processed foods showed the highest frequency of fruits and sweet potatoes. On the other hand, processed foods provided many sugar-rich products, such as liquid yogurt, hot cakes, and cereal, excluding white milk. The average sugar content was highest in processed milk products (13.9 g), followed by white milk (8.6 g), bread and snacks (8.0 g), other (4.6 g), and mixed grains (1.6 g). Of the total 216 snacks, banana flavored milk had the highest sugar content of 27.0 g, followed by strawberry milk (15.0 g) and castella (21.6 g). The findings are expected to be used as basic data for choosing the right snacks provided by childcare facilities and practicing reducing sugar intake.
We conducted a study to investigate milk and dairy products consumption among elementary school students to identify ways to increase their intake of milk and dairy products. We asked 518 students in Seoul to fill out questionnaire. Only 55.6% of the subjects consumed milk daily, and 43.7% of them drank at least 1 cup per day. The frequency and quantity of milk consumption were higher in male students than female students. The majority of the subjects consumed whole milk, and most students(59.5%) preferred flavored milk to whole milk. The reasons given for drinking milk included 'wanting to be tall'(66.1%) and 'for good health'(47.1%), while the main reason given for not drinking milk was stomach pain (68.4%). Records of having an unpleasant experience and upset stomach after drinking milk occurred at a higher rate for those who did not drink milk(84.2%) than for those who did(53.3%). Of the students questioned, 36.9% consumed dairy products other than milk 3~4 times per week, and liquid-type yoghurt(43.8%) and ice cream(35.4%) were the preferred dairy products among students. The reasons given for consuming dairy products were 'good taste'(56.6%), 'good to eat'(46.6%), 'wanting to be tall'(32.4%), and 'for good health' (25.4%). Among those students who did not consumed dairy products, the major reason given was 'family does not eat at home'(33.3%). After consuming the dairy products, 71.4% of participants thought that dairy products did not result in physical improvement. Most students had experienced purchasing milk and dairy products by themselves. When they bought milk or dairy products, the reasons given for making a particular selection were 'shelf-life'(61.6%) for milk, and 'favorite dairy products'(54.1%) for dairy products. According to participants, the factors that need to be considered for milk and dairy product consumption among elementary school students are 'higher nutrition' (60.8%), 'better sanitation'(57.3%), and 'better quality and taste'(55.2%).
This study was performed to investigate the consumption pattern of school milk programs for elementary school students. The subjects were 518 students residing in Seoul area. The survey was conducted by using a self-administered questionnaire, and the collected data were analyzed by SAS package. Of the subjects, 88.2% of the students were provided with a school milk program, and the number of the students was higher in male students than in female ones(p<0.05). 81.8% of them drink milk every day from the school milk program. For the degree of satisfaction for milk served in the school milk program, 47.9% of the students were satisfied. An upset stomach after drinking milk and poor taste of milk were the main reasons why milk consumption decreased. Only 30.7% of the subjects perceived that they should drink milk in the school milk program. And the subjects anticipated that flavored milk and yogurt should be served to promote milk consumption in a school milk program. Therefore, a proper food guide and a dairy education program should be developed for elementary school students.
