와송 분말을 첨가한 쌀머핀의 품질 특성 및 항산화 활성

Abstract

This study aimed to suggest the usability and optimal amount of Orostachys japonicus in foods. Orostachys japonicus powder was added at 0% (Con), 3% (O3), 5% (O5), 7% (O7), and 9% (O9) to rice muffins and the quality and antioxidant characteristics of the muffins were determined. The moisture content and pH of the muffins decreased as the amount of Orostachys japonicus powder added increased. The weight increased as the amount of Orostachys japonicus powder added increased, but the volume, specific volume, and baking loss rate decreased. The L- and b-values of the muffins decreased as the a-value increased. The texture, hardness, gumminess, and chewiness of muffins increased while adhesiveness, springiness, and cohesiveness decreased. Polyphenol, flavonoid, DPPH, and ABTS+ radical scavenging activity, as well as reducing power, increased as the amount of Orostachys japonicus powder added increased. In the sensory test, the 5-7% addition group showed high scores in appearance, flavor, taste, texture, and overall preference. The degree of flavor and astringency of muffins, which are evaluation items for characteristic strength, increased as the amount of Orostachys japonicus powder added increased, and the level of moistness decreased. Therefore, the addition of 5-7% of Orostachys japonicus powder is thought to have a positive effect on the muffins. The purpose of this study was to suggest the usability and optimal addition amount of Orostachys japonicus powder and to provide basic data on foods with Orostachys japonicus added.
