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.

This study sought to analyze the need for nutritional education to enhance the selection of desirable foods by adolescents. A total of 480 high school students in Incheon were surveyed and their responses were analyzed for the recognition of nutrition labeling and their consumption of processed foods and snacks. Almost all the students (93.1%) recognized nutrition labeling, but 54.6% rarely checked the nutrition labeling. The nutrients recognized as important in the nutrition label of processed foods were total fat/saturated fat/trans fat (3.75 out of 5), calories (3.68), and sodium (3.67) in that order. The recognition of the importance of calories was significantly higher in female students compared to male students (3.78 vs. 3.58, P<0.05). The information identified as important were the date of manufacture and expiration (4.21 out of 5), price (4.14), and the nutrition label (3.15). The preference for processed foods was highest in the order of beverages (4.03 out of 5), noodles (4.02), and frozen desserts (3.97), and the preference of females for processed foods was significantly higher than males (P<0.001). The time when snacks were most frequently consumed were before going to the academy (21.0%), after school (19.4%), and after attending private institutes (15.0%). The main reasons for using processed foods as snacks were taste (44.4%), 'no time to eat a meal' (26.4%), and low price (17.7%). In conclusion, while students mostly recognized nutrition labeling, the actual usage rate was low, and snacks were selected and consumed instead of meals for reasons such as attending academic institutes after school. Thus, to encourage the choice of proper processed foods and snacks for adolescents, practical nutrition education using nutrition labeling is needed.

The objective of this study was to investigate the consumption pattern of snacks-containing trans-fatty acid in adolescents living in the Kwang-ju area of Korea, and to analyze the relevance toward their eating behaviors, body composition, nutrient intakes, and consumption frequency of snacks-containing trans fatty acid. A survey questionnaire was developed in order to investigate general environmental factors, eating behavior, nutritional knowledge, and the consumption frequency of snacks-containing trans fatty acid. A total of 312 middle school students were surveyed. The collection rate was 97% and ultimately 282 cases were analyzed. Anthropometric measurements, body composition data, and nutrient intakes were also collected. The consumption frequencies for snacks-containing trans-fatty acid were negatively correlated with food behavior scores (p<0.01) however, pocket money and snack intake frequency per day were positively correlated with consumption frequency. Also, snack consumption frequency had some correlation with the subjects' anthropometric measurements and body composition data such as total body water (p<0.01), body protein (p<0.01), body minerals (p<0.01), and skeletal muscle mass (p<0.01). Finally, the consumption frequency of snacks-containing trans fatty acid was significantly correlated with calcium intake (p<0.05), it also showed correlations with vitamin A, retinol, ${\beta}-carotene$, and folic acid intake, although statistical significance was not verified.

Fish-frames are processing byproducts, which are left after obtaining fillets or muscle during fish processing. The fish-frame generally consists of muscle, collagen, calcium, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). We used fish-frame powder (FFP) of chum salmon and skipjack tuna to prepare and characterize snacks for human consumption with different proportions of FFP. The crude protein and lipid contents of fish-frames were 16.3 and 9.4% for chum salmon and 18.6 and 8.3% for skipjack tuna, respectively. The volatile basic nitrogen (30.6 mg/100 g) and browning index (0.393) of FFP from chum salmon were lower than those of FFP from skipjack tuna. Thus, the FFP of chum salmon was better for making snacks than that of skipjack tuna. Five snacks were prepared with 0, 10, 20, 30, and 40% (w/w) substitution ratios of FFP from chum salmon. The moisture content of the snacks decreased (33.6 to 11.5%) with increasing FFP substitution ratio, whereas crude ash (2.9 to 7.5%), protein (11.4 to 18.4%) and lipid (13.7 to 35.1%) increased. Sensory scores for the texture and taste of the snack with 30% FFP were significantly higher (p<0.05) than those for other snacks; the color and flavor scores of all snacks did not differ significantly. The major fatty acids in the snacks were 16:0 and 18:0 as saturates, 18:1n-9 as monoenes, and 18:2n-6 and 18:3n-3 as polyenes. Snacks with FFP contained small amounts of EPA (0.5 to 0.8%) and DHA (1.3 to 1.8%) in the total lipid composition. The total amino acid content (16.08 g/100 g) of the snack with 30% FFP was higher than that of the snack without FFP (11.18 g/100 g), and the major amino acids were aspartic acid, glutamic acid, glycine, leucine, and lysine. The calcium and phosphorus contents of the snack with 30% FFP were 1,272 mg/100 g and 854 mg/100 g, respectively, and their ratio was the optimal range (2:1 to 1:2) for body absorption efficiency.

Fried-fish snacks containing surimi are a popular seafood product in Asia. To prepare fried-fish snacks, various ingredients are added to surimi. Among them, starch is important for producing snacks of desirable texture and taste. We investigated the physicochemical properties of fried-fish snacks containing arrowroot, potato, sweet potato, corn, and tapioca starches. The fried-fish snack with arrowroot starch showed the highest drying rate; after drying for 3 hours, the water content was unchanged. None of the starches affected the total volatile basic nitrogen values of the fried-fish snacks, which were approximately 1.5 mg/100 g, indicating freshness. The fried-fish snacks with corn and arrowroot starches had the highest brightness (L) values and the fried-fish snack with tapioca starch, the lowest L value. The hardness value of the fried-fish snack with tapioca starch was significantly higher than that of the other fried-fish snacks. In the sensory evaluation, the fried-fish snacks with arrowroot starch showed the best overall acceptance.

The purpose of this study was to find out how much they have several aspects of food related knowledge and eating behaviors of high school students in Sungnam area. The self-administrated questionnaire was used. The result were as follows: 1. The average height of boys and girls was $172.6{\pm}0.7$ cm and $156.3{\pm}1.5$ cm respectively. The average weights of them were $62.4{\pm}0.5$ kg (male) and $47.2{\pm}0.8$ kg (female). BMI (Body Mass Index) of them were $20.74{\pm}0.14$ (male), $18.82{\pm}0.28$ (female). The average age is 16.7 years old. 2. The 66.5% of the subjects were spent more than one-third of their pocket money in buying on light meals during three times a week. There were significant differences between income level of family. Boys spent more money on each meal than girls. And significant differences were also obserbed by their residence area and Bundang residences spent more in buying snacks. 3. The rate of skipping meals was 51.2% in boys compared with 68.0% in girls. The frequencies of buying snacks instead of main meal were high in girls. Time limits in eating may possibly be the main reason for skipping meals (59.8%), especially in the morning. Skipping a breakfast becomes general eating habits in high school students, because of pressure for time to go to school. 4. It is required that parents should be taught to prepare balanced lunch box for their children because the rate of students who prepared two lunch boxes are 49.4%. 5. The students took snacks once or twice a day. They usually bought snacks in school concessions (51.8%) and they selected items of snack instinctivly. The girls ate snacks during lunch break time (31.7%) and after dinner (23.6%). Boys ate snacks after dinner (29.1%). Preference of foods were different by sex. Boys preferred bread (31.7%), milk and otherdairy products (80.8%), cola and soda (42.0%) as their snacks between meals. Girls selected biscuit, chip, beverage, coffee as their snacks, frequently. 6. BMI value of the group who ate between meals more than three times a day was lower $(18.78{\pm}0.65)$ than that of the group who ate nothing between meals $(20.71{\pm}3.79)$. 7. As for the nutritional knowledge, the students generally had higher correct rate of answer about which nutritive components of food has (76.6%). But they had lower knowledge on questions of nutritive values in food (10.6%). There was a meaningful relation between favorite food and nutritional knowledge. In conclusion, there were some problems on nutritional knowledge and eating habits among the high school students. Therefore, it was required that girls should be learned to recognize the importance of breakfast and needed to select balanced meals and snacks. And it was required that the nutrition education should be complemented to motivate and improve practical eating behaviors.

Persimmon has been known to help alcohol intoxication in Korea for a long time and is prepared as a processed food. The effect of dried persimmon snacks on alcohol metabolism was determined in vivo. Eight Korean men (25~27 years old) were administered 3.5 mL/kg of alcohol (22.5%, w/v) with or without a dried persimmon snack (2g/kg). The levels of alcohol in the blood and of acetaldehyde in the blood and the urine were determined by alcoholmeter and assay using alcohol dehydrogenase and HPLC, respectively. All subjects showed decreased levels of alcohol in blood, and six subjects showed a decrease of alcohol in urine after consumption of ethanol with dried persimmon snacks. Concentration of acetaldehyde in the blood an urine decreased significantly in three and five of the eight subjects, respectively. Reduction was more significant for alcohol than for alcohol than for acetaldehyde with administration of ethanol and dried persimmon snacks. This in vivo result suggests that dried persimmon snacks are effective in decreasing th concentration of alcohol after alcohol intake.

This study was conducted to evaluate menu pattern and nutritional contents of snack menus provided by child care information centers in Seoul. Snack menus during March 2013 (morning snack : 125 cases, afternoon snack : 100 cases), including information on portion size, were collected from five child care information centers, after which the number of menu items, menu patterns, and nutritional contents were analyzed. About two-thirds of total snack menus included two menu items. There were significant differences in service time (morning & afternoon snacks). 'Beverage+Food' pattern (66.7%) was the most commonly used; 'Beverage' pattern was significantly higher in morning snacks (10.4%) than in afternoon snacks (1.0%). Morning and afternoon snacks provided 124.5 and 170.6 kcal of energy and 116.4 and 90.9 mg of calcium, respectively, which are 8.9% and 12.2% as well as 19.4%, and 15.2% of children's daily energy and calcium requirements. To improve the quality of food and nutrition offered to children through snacks at child carre centers, a more detailed snack menu plan as well as nutritional guidelines for institutions should be developed.

Purpose: The storage life of pearl millet-based, deep fried, ready-to-eat snacks, packaged in aluminum-laminated polyethylene having a thickness of $50{\mu}m$ (with and without nitrogen) was evaluated under storage conditions of $38{\pm}2^{\circ}C$ and 90% RH. Methods: The moisture content, free fatty acids (FFA), peroxide value, and crispness of the snack were evaluated throughout the storage period. The moisture content, FFA, and peroxide value increased with an increase in storage period, but the increase was less in packages flushed with nitrogen gas. The crispness decreased with an increase in the storage period, for snacks both with and without nitrogen packages. However, the decrease was less in nitrogen-flushed packages. FFA and peroxide values were strongly correlated with the moisture content of the snack. The storage life of the snack was found to be 60 and 45 days in packages with and without nitrogen respectively. Conclusions: The snack's predicted storage life, for snacks with and without nitrogen packages, was determined as 294 and 254 days respectively.

This study was carried out to investigate the eating habits and preference of snacks for students in Chungnam province. Questionnaires were collected from 333 students, which were divided into male and female, food nutrition majors and non-majors, and weight groups according to BMI. The results obtained were as follows; 1. 62.8% of students responded that they were healthy. A significant difference on the health question was found between male and female students (p<.05). Male students responded more positively to the question related to health than the females, saying they felt healthy (71.1%). There was no significance between the different majors, but a significant difference was found in weight groups compared to normal groups (p<.05). 2. 72.1% of respondents enjoyed omnivorous meals. The significant differences were not found in gender groups and major groups. However, there was a significant difference between the weights of the students (p<.01). 3. Most of the students liked sweet foods (42.3%). The significant difference was found in gender groups for food tastes. The male students preferred spicy foods (37.0%), but the females preferred sweet foods (49.5%). Taste for the major and weight groups was not significantly different. 4. 50.5% of respondents answered that they frequently ate snacks. The significance was found in gender groups (p<.01). The females had a higher intake of snacks than the males. The significant difference for taste was not shown in the major group, but was found in the weight groups (p<.05). 5. Students preferred snacks and candy (16.8%). The males liked dairy products (19.3%), while the females preferred snacks and candy (23.7%). Students majoring in food nutrition have a tendency to prefer snacks (32.1%). Appropriate calorie intake and desirable eating habits should be recommended for healthy control and maintenance of students through eating nutritionally balanced foods.
