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.
