Abstract

The purpose of this study was to analyze the labeling of commercial protein bars in Korea and USA to develop Korean protein bars. Furthermore, we compared protein contents of products with daily protein intake, DRI, and AMDR. The protein bars were sampled in off- and on-line markets of both countries, with 17 in Korea and 113 in the US. As the results, since US products have bigger than one serving size than Korean ones, the intake of overall nutrients is higher, especially protein and sodium. Protein contents (per 100 g) of products in US were higher than those of Korea. The highest protein was soy protein isolate (SPI) in Korea and whey protein isolate (WPI) in the US. This is thought to be influenced by the preference and familiarity of food according to the country. In conclusion, since there are difference in eating habits, intake and preference of the protein source, it is necessary to develop suitable protein bars for Koreans. Therefore, this research provides the baseline of protein bars for consumers to choose products.

본 연구는 한국인에게 적합한 단백질 바를 개발하기 위하여 한국과 미국의 시판되고 있는 단백질 바의 라벨 분석을 하였다. 또한 조사한 단백질 바의 단백질 함량과 일일단백질섭취량, 단백질 권장섭취량(DRI), 그리고 단백질 에너지섭취분율(AMDR)과 비교 분석하였다. 단백질 바는 두 나라의 오프라인과 온라인 마켓을 통해 한국의 17개 제품과 미국의 113개 제품을 수집하였고, 영양소 함량과 원재료를 조사하였다. 그 결과, 미국의 단백질 바가 한국의 것에 비해 1회 제공량이 더 많기 때문에 전체적인 영양소의 함량도 높았는데, 특히 100g으로 환산하였을 때 단백질과 나트륨의 함량은 큰 차이로 높았다. 원재료를 통한 단백질 소재를 분석하였을 때, 한국은 분리대두단백(SPI)이, 미국은 분리유청단백(WPI)이 가장 많이 이용되었다. 이는 나라별 식품의 선호와 친숙함에 영향을 받은 것으로 보인다. 결론적으로, 두 나라의 식습관과 단백질 급원에 대한 섭취 및 선호가 다르기 때문에 한국인에게 적합한 단백질 바의 개발이 필요할 것으로 사료되며, 본 연구의 결과는 소비자들이 단백질 바를 선택하는 데 도움을 줄 것이다.
