The objectives of this study were to develop Korean dishes acceptable for quick-service Korean food restaurant franchising operations in the U.S. and to test consumer preferences of 6 Korean dishes developed. One hundred American consumers evaluated beef(Bulgogi), pork(Jeyuk-bokkeum), chicken(Dagkalbi), noodles with seasoned vegetables(Japchae), braised tofu(Dubujorim), and stir-fried kimchi (Kimchi-bokkeum). Consumer preferences for color and aroma of the three dishes(Bulgogi, Jeyuk-bokkeum and Dagkalbi) were not different with most indicating they liked these attributes. Bulgogi was preferred over Dagkalbi and Jeyuk-bokkeum was least acceptable. Consumers rated the flavor of the Bulgogi from a little too mild to just right while both the Dagkalbi and Jeyuk-bokkeum were rated from just right to too strong. Overall acceptance was inversely related to spiciness. Bulgogi and Dagkalbi were ranked significantly higher than Jeyuk-bokkeum with Bulgogi receiving a slightly higher score. Overall acceptance was higher for the Japchae than the Kimchi-bokkeum. Dubujorim was intermediate and not preferred or disliked more than either of the others. Consumers rated the flavor of the Japchae and the Dubujorim higher than the Kimchi-bokkeum, indicating that the flavor of the Kimchi-bokkeum was too strong. Almost half indicated both the Dubujorim and Kimchi-bokkeum were slightly or much too hot. The Japchae and the Dubujorim were ranked equally high and significantly higher than the Kimchi-bokkeum. We suggest that control of spiciness is a main factor to develop Korean dishes acceptable for quick-service Korean food restaurant franchising operations in the U.S.

본 연구는 미국에서 우리나라 전통과자인 한과의 판매 가능성과 수용여부를 파악하기 위해서 미국인 대학생을 대상으로 설문조사와 관능검사를 실시한 결과이다. 설문 시에는 적절한 양과 가격, 섭취경험, 구입의사 등에 대해서 조사하였고, 관능검사 시에는 다식, 산자, 약과, 엿강정에 대해서 색깔-모양- 냄새와 greasiness, sweetness, firmness, adhesiveness, crispiness, dryness, overall acceptance에 대해서 평가하였다. 관능검사 결과 약과는 greasiness 가 유의적으로 높았고(p<0.01), 산자와 엿강정은 crispiness 가 유의적으로 높게 조사되었다(p<0.01) 전체적인 수용도는 다식이 유의적으로 낮게 조사되었다(p<0.01). 조사대상자는 한과를 스낵(42.9%)으로 이용하겠다고 가장 많이 응답했다. 그러나 구입의사에 대한 항목에서는 시식 후 90.5% 가 구입의사가 없다고 응답했으므로 한과의 세계화를 위해서는 각 나라의 식문화를 고려하여 각 나라 사람들에게 친숙한 향과 맛을 첨가하여 제품을 생산할 필요가 있다고 사료된다.

Differences in dietary intake of Korean Americans (KA) by the length of residence in the U.S. were studied in relation to health and disease patterns in Michigan. Of 1860 questionnaires mailed, 637 (34.3%) responded with demographics, anthropometrics, self-reported disease patterns, lifestyle, and dietary patterns (93-item FFQ developed for KA). Complete responses were available for 498 people (263 men,253 women, aged 30-87 yr), who were then divided into three groups based on the number of years lived in the U.S.: 15y, 16-25y, 26y. Age-adjusted weight, height, BMI, and waist to hip ratio were within the normal ranges and did not differ among the three groups. Chronic diseases frequently reported in men and women (age-adjusted) included hypertension (14.4%, 14.1%), digestive diseases (5.4%, 8.5%), diabetes (3.6%,4.9%), and arthritis(3.3%, 12.5%), respectively. The length of residence in the U.S. was inversely associated with the age-adjusted prevalence of digestive diseases (12.4%, 6.5%, 0.4% in men, 13.0%, 11.7%, 0% in women). The length of residence was positively associated with health consciousness, receiving regular health care, taking supplements regularly, and exercising, while inversely related to smoking. The majority favored American foods for breakfast and Korean foods for dinner. Foods frequently consumed included cooked rice (w/other grains). kimchi, coffee (w/cream and sugar),bread (white and dark), citrus juice, milk (low fat and skim), lettuce and cucumber, apple, seaweed, and soda. Intake frequency of the Korean starch food group was inversely associated with the length of residence for both men and women (p<0.001), but not with the American starch food group. Fat intake did not differ by the length of residence in the U.S. The dietary changes were associated with the length of residence and chronic disease patterns for the first generation of KA, which should be further examined 'for the subsequent generation of KA.
