  • Objectives: This study investigated the menu and nutritional contents of convenience store lunchboxes, and evaluated the nutritional content by meal type, price, and store brand. Methods: In September 2019, 93 convenience store lunchboxes from the top five franchise stores were purchased. Relevant information on price, food weight, food ingredients, cooking methods, and nutrition labeling were subsequently collected. Nutritional content was evaluated based on the daily value (DV) and Index of Nutritional Quality (INQ), and energy contribution of carbohydrate, protein, fat, saturated fat and sugar was compared with the recommended range. Results: Most lunchboxes included the food groups; grains/starches, meats/fish/eggs/legumes, and vegetables. However, none provided fruits, and only a few lunchboxes provided milk/milk products. Stir-frying, deep-frying, and pan-frying were the most frequent methods of cooking. The average energy content of the lunchboxes was 736.6 kcal, whereas the average contents of protein, fat and saturated fat were higher than 40% of the DV, and sodium content was 66.8% of the DV. The contents of most nutrients in traditional type lunchboxes were higher, as compared to nutrients in onedish type lunchboxes. Considering pricing of lunchboxes, protein and sodium contents were higher in the higher-priced lunchboxes as compared to lower-priced lunchboxes, but there were no differences in the INQs. The contents of energy, protein, fat, saturated fat, and cholesterol significantly differed by brand. Conclusions: Our results indicate that convenience store lunchboxes contain high levels of protein, fat, saturated fat, and sodium. The nutritional contents differed by meal type, price, and store brand, and higher price did not imply higher nutritional quality. We propose the need to educate consumers to check nutrition labels and purchase appropriate lunchboxes. Manufacturers also need to make efforts to reduce the amounts of fat, saturated fat, and sodium, and not provide protein in excess.

  • To investigate the nutritional quality of packaged meals produced by packaged meal manufactures, a nutritional evaluation was conduced. Samples examined in this study were 95 Products which composed of 86 Doraks, 7 Kimplabs and 2 Yubuchopabs Produced in packaged meal manufactures in Seoul City and Kungki-do province The distribution of food groups showed that amounts of animal foods were abound, but amounts of green vegetables, limited in Dosirak comparing to one meal RDA levels. Amounts of meats, fishes and shells are increased more than amounts of egged and legumina with increase of price of Dosirak. The total kinds of food and the amounts of certain food in Kimpab and Yubuchopab were lower than Dosirak. The energy and protein contents of Dosirak were found to be higher than one meal RDA levels, with exception of protein content in Dosirak of the price 1000 won. The contents of energy and protein in Kimpab and Yubuchopab are less than one meal RDA levels. Calcium and iron contents in Dosirak, and calcium content in Yubuchopab were present in excess compared to the one meal RDA. However, In Kimpab, calcium and iron contents were lower than the one meal RDA. On the whole, vitamin contents of Dosirak were sufficient whereas vitamin contents of Kimpab and Yubuchopab were lower than the one meal RDA. Number of side dishes used in Dosirak were 6-23 items depending on prices. Guidelines were suggested for effective nutritional quality control of packaged meals.

  • Objectives: This study evaluated nutritional quality of convenience store meal boxes according to store company and meal price. Methods: In May 2020, 71 meal boxes from five major convenience store companies were collected. Respective weights of all dishes and food ingredients included in each meal box were measured with a digital scale. Information on nutritional contents was collected from nutrition fact panels on packages. Food group patterns, dietary diversity scores (DDS), and dietary variety scores (DVS) were analyzed. Nutritional contents, i.e., amounts of energy, protein, and sodium, and percentages of energy from carbohydrate, sugar, fat, and saturated fat were compared with respective standards based on the 2020 Dietary Reference Intakes for Koreans. Comparison was made among five companies (Company A, B, C, D, E) and three price groups (≦ 4,200 won, ≧ 4,300 and ≦ 4,500 won, ≧ 4,600 won). Multiple regression analyses were conducted to examine the difference of nutritional contents according to company and price, respectively while holding the other variable constant. Results: DDS, but not DVS, significantly differed among companies. The percentages of meal boxes meeting the nutritional standards of sodium significantly differed among companies; the percentage was highest in companies B (75.0%) and C (73.3%). "Company" was associated with amount of energy, protein, and sodium, and percentage of energy from saturated fat. "Price" was associated with the amount of energy and percentage of energy from carbohydrate. The average number of satisfied standards was highest in companies B (5.0) and C (4.0). About two-thirds of the meal boxes provided less amount of energy than the standard; the percentage of such meal boxes was highest in meal boxes with price of 4,200 won or lower. Conclusions: There were significant differences in the nutritional quality of meal boxes according to "company". Meanwhile, higher-priced meal boxes did not necessarily ensure better nutritional quality.

  • This study was conducted to evaluate the nutritional value of locally produced organic agricultural by-products to substitute imported organic feeds for organic ruminant farming. Imported organic feeds (corn grain, soybean meal, soybean seed, oat grain, barley grain, wheat grain, buckwheat, sunflower seed meal) and byproducts (rice bran, grape seed meal, rice straw, soybean hull, soybean curd, rice hull, green kernel rice, and crushed rice grain) were analyzed for chemical composition and NDF, ADF, mineral, and amino acid contents and anti-nutritional factors. Dry matter, NDF and ADF contents in organic feeds were higher than those in conventional feeds. Especially, the 9.65% fat content of organic soybean meal was 6 times higher than the 1.95% fat content of conventional soybean meal. Fat contents of rice bran, grape seed meal, green kernel rice, and crushed rice grain were 25.66, 6.09, 3.57 and 1.59%, respectively. Protein contents of soybean hull and soybean curd were 14.68 and 19.87%, respectively, which are highest among organic by-products. Levels of aflatoxin in all feeds were below the safety level. Therefore, organic rice bran, green kernel rice and crushed rice as energy source, and soybean hull and soybean curd as protein source could partial replace imported feeds for organic ruminant farming.
