  • The purpose of this study is to confirm the relevance between the frequency of beverage consumption and periodontal disease among Korean adults. The data used for analysis was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). The subjects were 9,042 adults aged 19 to 64. In non-smoking group, people with periodontal disease had less intake of milk, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In smoking group, people with periodontal disease had less intake of milk, liquid yogurt, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In the results of verifying the correlation between periodontal disease and beverage intake in accordance with the matter of smoking after revising the socio demographic characteristics, in non-smoking group, the intake of coffee was correlated with periodontal disease. In smoking group, the intake of milk was correlated with periodontal disease. Since the intake frequency of some beverages is related to periodontal disease, there should be guidelines on beverage consumption during the periodontal disease prevention education.

  • The soy milk prepared from soy protein concentrate was treated with microbial protease or papain. Growth and acid production by Lactobacillus acidophilus in soy milk containing partially hydrolyzed proteins were investigated. Sensory evaluation of yogurt beverage prepared from protease treated soy milk was also performed. Protease treatment of soy milk enhanced acid production by lactic acid bacteria, particularly in case of microbial pretense and simultaneous treatment by two types of protease showed synergistic effect. pH and number of viable cells were not affected markedly by pretense treatment. Microbial pretense treatment up to 15 minutes or papain treatment up to 45 minutes enhanced acid production, but further treatment up to three hours did not affect the acidity markedly. rho sensory evaluation showed that overall acceptability and taste of soy yogurt beverage were slightly improved when soy milk was treated with microbial pretense of 0.2% or papain of 0.2%. The amount of non-protein nitrogen considerably increased by pretense treatment of 15 minutes and it increased gradually by further treatment up to three hours.

  • Vegetarians have claimed and actively promoted the advantages of plant-based alternative milks as the best option for human nutrition and health, compared to the natural dairy milk. However, numerous scientific evidences and reports have demonstrated that the natural milk possesses more beneficial nutrients and bioactive components than artificially manufactured plant-derived milks. The biochemical and nutritional advantages and functionalities of natural dairy milk cannot be replaced by man-made or crafted plant-based beverage products. On the other hand, the tremendous increase in production and consumption of the plant-based alternative milks in recent years has led a serious business downturn in traditional roles and stability of the dairy industry, especially in the major dairy producing Western countries. Although plant-based milk alternatives may have some benefits on nutrition and health of certain consumers, the plant-derived alternative milks may not overshadow the true values of natural milk. Milk is not a high fat and high cholesterol food as animal meat products. Unlike plant-based alternative milks, natural milk contains many bioactive as well as antiappetizing peptides, which can reduce body weight. It has proven that taking low-fat, cultured and lactase treated milk and dairy products with other diversified nutritionally balanced diets have been shown to be healthier dietary option than plant-based milk/foods alone.

  • The purpose of this study was to estimate beverage consumption frequency and determine related problems of elementary school students in Chungnam. The survey was conducted with 488 students(boys=230, girls=258) using a questionnaire. The average age of the students was 10.1 years old, thir average height and weight were 145.1 cm and 39.5 kg, respectively and the obesity index was -1.3%. The frequencies for breakfast, lunch and dinner were 5.8 times/week, 6.7 times/week and 6.4 times/week, respectively. Regarding the frequency of snacks, high response rates for 'once/day'(38.3%) and 'none' (30.5%) were observed. Nutrition label on beverages were identified rarely(39.1%), nearly never(19.7%), and never(12.9%). The choice factors in selecting beverage were taste, nutrition, and price. For the type of snack most often consumed, fruit or juice was 25.8%, snack items were 25.2%, bread was 24.8%, dairy products were 7.6%, beverages were 7.0%, noddles were 6.2%, and rice cakes were 3.5%. The kinds of favorite beverages were carbonated drinks(30.3%), functional drinks (24.4%) and milk and yoghurt(23.8%), and main reason for the choice of beverage was "it tastes good". For the point of time that students wanted to drink a beverage, "when I feel thirsty" appeared most often for dairy products and beverages and the next most frequent answer was "after exercise". Therefore it may be necessary to administer systematic nutritional education on perception on nutrition fact label of beverage. And it is thought that plan for proper beverage consumption in elementary school students may be established.

  • Thermal pasteurization has been effectively used for decades as a method to extend the shelf life of milk and to inactivate any pathogenic bacteria that it may contain; however, it can negatively affect the nutritional properties of milk. In recent years, the food industry has sought new, less aggressive technologies that affect food freshness and its nutritive and health benefits less significantly. Various means have been used to extend the shelf life of dairy foods, such as high-pressure processing, irradiation, ohmic heating, and pulsed electric field (PEF) technologies. Of these, PEF technologies are potential alternatives to traditional thermal milk pasteurization, owing to their advantages in minimizing sensory and nutritional damage. In this review, we have primarily focused on the feasibility of applying PEF technologies to the sterilization of dairy products and briefly discussed whether they should be adopted for use in the dairy beverage industry in the future.

  • This study was carried out to find a cholesterol removal rate, flavor development, and bitter amino acid productions in Cheddar cheese treated with -cyclodextrin (${\beta}-CD$): 1) Control (no homogenization, no ${\beta}--CD$), and 2) Milk treatment (1000 psi milk homogenization, 1% ${\beta}-CD$). The cholesterol removal of the cheese were 79.3%. The production of short-chain free fatty acids (FFA) increased with a ripening time in both control and milk treated cheese. The releasing quantity of short-chain FFA was higher din milk treated cheese than control at 5 and 7 mo ripening. Not much difference was found in neutral volatile compounds production between samples. In bitter-tasted amino acids, milk treatment group produced much higher than control. In sensory analysis, texture score of control Cheddar cheese significantly increased, however, that in cholesterol-reduced cheese decreased dramatically with ripening time.

  • Soy milks prepared from full-fat soy flour, defatted soy flow, soy protein concentrate (SPC) and soy protein isolate (SPI) were fermented with Lactobacillus acidophilus. Effects of lactic fermentation on the flavor and volatile compounds of soy milks were investigated. Sensory evaluation showed that the flavor of soy yogurt beverages was inferior to that of milk yogurt beverage and the flavor of SPI-yogurt beverage was better than that of other soy yogurt beverages. SPI-milk fermented with L. acidophilus was more acceptable than unfermented SPI-milk. Lactic fermentation reduced n-hexanal in SPC-milk and SPI-milk while it increased diacetyl in both soy milks.

  • The purpose of this study was to investigate the relation of the fast food and beverage intake on sociality and anger expression of adolescents. Questionnaires were distributed to the adolescents of 599 middle and high school students in Busan. According to the results, the preference-intake frequency analysis (PEA) on fast food grid, high preference and high intake frequency were 'dukbokki', 'chicken' and 'mandu' and low preference and high intake frequency were 'ramyon', 'gimbab. PEA on beverage grid, high preference and high intake frequency were 'milk-dairy product', 'fruit juice', 'isotonic beverage' and low preference and high intake frequency were 'carbonate drink'. The intake frequency of 'pizza', 'sandwich', 'udong', and 'dukbokki' had a positive relationship with sociality. 'Hamburger', 'chicken', 'french fry', 'gimbab', 'mandu', and 'ramyon' showed a positive relationship with anger-out. The intake frequency of 'carbonated drink' had a negative relationship with anger-control, but 'green tea' showed a positive relation with it. 'Carbonate drink', 'isotonic beverage', 'coffee', and 'milkshake' had a negative relationship with anger-out. The explanation power ($R^2$) of intake of fast food and beverage on sociality was $0.019{\sim}0.038$, and 'carbonated drink' and 'coffee' had a negative influence on sociality. The explanation power ($R^2$) of intake of fast food and beverage on anger expression was $0.011{\sim}0.041$, and 'carbonated drink' had a negative influence on angercontrol. 'Hamburger', 'carbonated drink', and 'coffee' showed a positive influence on anger-out. From these results, it was necessary to develop the practical eating-out habits program on proper fast food and beverage choice for adolescents.
