초록/요약

The demand for high protein nutrition bars that can easily replace meals is increasing due to busy life styles and changes in life patterns of modern people. In this study, we developed a sample of four flavors (grain, chocolate, coconut, and cinnamon) that are popular domestically and abroad by adding soy protein isolate, which is the most commonly used protein enhancer in Korea. All developed samples are high-protein bars containing more than 23% protein per 100 g, according to FDA regulations. A survey was conducted on 117 consumers in their 20s∼30s to evaluate purchasing behaviors for bar snacks and the palatability of the developed high protein bars. According to the analysis of consumers' purchase behavior of snack bars, they generally prefer snacks (59.8%) and consume them as meal substitutes (49.0%). Further, most consumers buy the bars 'themselves' (49.6%), 'one at a time' (53.4%), and 'at convenience stores' (61.4%). The palatability of the developed samples showed the highest preference for grain flavor and the lowest preference for chocolate flavor. In addition, the taste and flavor preferences were examined in the same order by sample. The degree of hand stickiness, crispiness, and texture preferences seem to be driven by the degree of processing, such as dryness of the added ingredients, from of powder, etc. In addition, the result of Correspondence Analysis showed that the preference for the sample is increased when the product name can be reminiscent of the taste or has a familiar or healthy taste. Also, the appearance is important due to the characteristics of the bar product. © 2020 Korean Society of Food Science and Nutrition. All rights reserved.
