Objectives: This study investigated the utilization and satisfaction of lunchbox by considering the dietary lifestyle of the consumer, in order to refine the purchasing behavior of adults with experience in using lunchboxes, and to provide basic data for efficient menu configuration and direction towards improvement. Methods: A total of 600 adults in Seoul and Gyeonggi-do answered a self-administered questionnaire designed to investigate general characteristics, utilization, menu preference, satisfaction, prospection, and improvement of lunchbox, according to the dietary lifestyle. Results: The study subjects were classified into 5 groups: 'taste seeking group', 'safety seeking group', 'health seeking group', 'economic seeking group' and 'convenience seeking group. Considering purchase value of the lunchbox, the 'taste seeking group' had a high utilization rate (35.1%) for prices less than 4,000 won (P < 0.05). Lunchboxes were mainly purchased at the lunchbox store (43.3%) and convenience store (37.7%). The important factor that contributed to purchasing a lunchbox was taste (61.3%), which was highest in the 'taste seeking group' (P < 0.01). The 'health seeking group' showed the highest preference for the low-salt diet lunchbox menu (26.0%) (P < 0.05). The satisfaction of 'health seeking groups' was lowest when considering addition of condiments (2.34%), origin of ingredient (2.59%), and provided calorie (2.81%) (P < 0.05). The overall response indicated future use of the lunchbox (69.6%) (P < 0.01); 35.8% respondents recommended the purchase of lunchbox, where convenience of purchase was the highest factor contributing to recommendation (50.2%) (P < 0.05). Conclusions: Taken together, our results indicate that taste was emphasized in every group purchasing the lunch box. Convenience of purchase was the highest factor contributing to satisfaction, which was relatively low when considering addition of condiments, nutrition and origin of ingredients. We propose that it is necessary to improve the development of various menus for increasing satisfaction by selecting the right ingredients contributing to good health of the consumer.

Purpose: This study was to evaluate the microbiological quality of salads in lunchbox's based on the holding time and temperature at convenience and franchise stores. Methods: Cabbage salad and crab meat salad were targeted for microbiological quality assessment. They were tested for aerobic plate counts, coliforms, Escherichia coli, Staphylococcus aureus and Enterobacteriaceae and assessment were performed by Korean Food Standards Codex. Results: In cabbage salad at convenience franchise store's at $5^{\circ}C$, the aerobic plate counts did not exceed the Korean Food Standards Codex. For cabbage salad stored at $25^{\circ}C$, the aerobic plate counts was 5.08 log CFU/g we hours after purchase, which exceeded the Korean Food Standards Codex. In case of cabbage salad in franchise store, the E. coli and S. aureus count exceeded Korean Food Standards Codex 3 hours after purchase. Microbiological analysis did not exceed the Korean Food Standards Codex at $5^{\circ}C$ in crab meat salad in convenience store. At $25^{\circ}C$, the aerobic plate count was detected at 4.45 log CFU/g after 32 hours, coliforms, E. coli, and S. aureus did not detect, but Enterobacteriaceae was found to be 2.34 log CFU/g after 9 hours in franchise store's crab salad. Coliforms was detected at 1.18 log CFU/g after 3 hours, and S. aureus was detected at 2.04 log CFU/g after 6 hours at $25^{\circ}C$ in the franchise store. The lunchbox' salad under cold storage ($5^{\circ}C$) generally meet the Korean Food Standards Codex. Conclusion: The results indicate an urgent need to implement proper management guidelines for the production of lunchbox foods to ensure microbiological safety, and to improve the shelf life from production to consumption.

본 연구는 효율적인 정보전달을 위한 편의점 도시락 레이블에 관한 연구로써, 구매자들이 원하는 정보의 중요도를 파악해 도시락 구매 시 구매자들에게 도움을 줄 수 있는 레이블을 정립하는 데 그 목적이 있다. 연구방법으로는 문헌 연구와 설문조사를 통해 구매자들이 도시락을 구매할 때 중요하게 생각하는 요소와 레이블에서 확인하는 정보 및 그 정보들의 중요도 순서를 분석하였다. 연구결과 도시락 구매자들이 중요하다고 생각되는 레이블 정보는 가격, 유통기한, 칼로리, 도시락 구성요소, 제조일자 순으로 나타났다. 또한, 레이블을 확인하지 않는 구매자들은 가독성이 떨어지는 레이블을 지적했다. 본 연구는 구매자들이 중요하다고 생각하는 정보들을 레이블에 새롭게 정립한다면 구매자들이 레이블을 통해 쉽게 정보를 확인하고 구매할 수 있을 것으로 기대한다.

본 연구는 편의점 도시락을 이용한 경험이 있는 성인 817명을 대상으로 식생활 라이프 스타일에 따른 편의점 도시락 이용현황과 만족도 차이를 분석하였고 편의점 도시락 시장에 효율적인 메뉴 구성과 개선 방향을 제안하는 기초자료를 제공하고자 하였다. 식생활 라이프 스타일 유형을 군집분석한 결과는 미각추구 집단, 경제추구 집단, 편의추구 집단, 건강추구 집단 등의 4가지 집단으로 군집화되었다. 도시락 이용현황을 살펴보면 도시락 제품 구매가격은 3,500~4,000원이었고, 도시락은 주로 점심 식사용으로, 혼자 먹는 것으로 나타났다. 편의점 도시락에 대한 정보를 얻는 곳으로는 편의점 매장, 인터넷 SNS 순이었다(p<0.05). 도시락은 영양성분을 고려하여 구매하였고(p<0.001) 중요한 영양소는 단백질, 열량, 나트륨이라고 하였다. 도시락의 용기는 위생적이고 청결해야 하며 용기 표면에 제품에 대한 정보를 부착하는 것을 중요하게 생각하고 있었다(p<0.01). 4개의 군집 중 경제추구집단은 도시락의 맛(3.66점)과 양(3.60점)에서 가장 만족도가 높았고(p<0.001), 다음은 가격(3.49점), 열량(3.43점)순이었다(p<0.01). 건강추구 집단은 메뉴의 다양성(3.76점)에서 만족도가 높은 반면 편의추구 집단은 메뉴의 다양성(3.47점)에서 만족도가 낮게 나타났고(p<0.05), 모든 집단에서 도시락 구매의 편리성(p<0.001)과 제품브랜드의 신뢰성, 다양한 할인제공도 만족하는 것으로 나타났다. 그러나 음식의 영양과 조미료의 첨가 여부는 상대적으로 낮은 만족도를 보였다. 도시락의 밥종류로는 백미밥을 선호하였고(p<0.001) 좋아하는 식재료는 육류인 것으로 나타났다(p<0.01). 모든 집단에서 밥과 찬으로 구성된 도시락을 좋아하였고 저염식과 고단백식을 지향하였으나 유의적인 차이는 없었다. 앞으로도 편의점 도시락은 계속 이용할 것이며(p<0.01), 주변인에게 구매의 편리함과, 저렴한 가격, 신선한 재료, 풍부한 영양 등으로 도시락 이용을 추천하겠다고 하였다. 본 연구의 조사결과 모든 집단에서 가장 중요한 요인은 맛으로 나타났으며, 편리성에서 가장 높은 만족도를 보였지만 음식의 영양과 조미료의 첨가 여부는 상대적으로 낮은 만족도를 나타냈다. 따라서 편의점 도시락 시장이 성장하기 위해서는 도시락의 품질개선과 다양한 메뉴 개발 등이 이루어져야 할 것으로 보인다.

This study compared and analyzed the importance-satisfaction regarding the selection attributes of the convenience store focusing on PB lunch box for consumers of 20s and 30s. According to the research results, the importance of factors such as easy purchase, time reduction, convenient intake were found to be high among the selection attributes of the convenience store PB lunchbox and those of factors such as confirmation of food ingredients, nutrition, and new taste were found to be relatively low. In addition, factors with high satisfaction included easy purchase, convenient intake, time reduction, while factors with low satisfaction were confirmation of food ingredients, nutrition and hygiene. The results of the IPA analysis were as follows: The $1^{st}$ quadrant (Keep up the good work) included convenience, time reduction, easy purchase, convenient intake, convenient cooking method, and convenient packing container Etc. $2^{nd}$ quadrant (possible overkill) includes origin labeling and the 3rd quadrant (low priority) includes packing container design, convenient storage, consistency of quality and taste, good taste, moderate amount, new taste, one meal, moderate quantity and quality, inexpensive intake, and hygiene Etc. $4^{th}$ quadrant was found to include no corresponding factors.

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.
