참죽 분말을 첨가한 매작과의 품질 특성 및 항산화 활성

Abstract

Cedrela sinensis is a Korean traditional wild herb that has a special taste and aroma. This study is conducted to investigate the effect of Cedrela sinensis powder on the antioxidant activity and the quality characteristics of Maejakgwa (Korean traditional cookie). Maejakgwa was prepared with different amounts of Cedrela sinensis powder (in ratios of 0, 5, 10, 15 and 20% to the flour quantity). The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenol content in Cedrela sinensis powder and Maejakgwa. For analyzing the quality characteristics, the bulk density and pH of the dough, moisture contents, volume, color, texture profile analysis, and sensory evaluations were measured. The bulk density, moisture contents, volume, total phenol contents and DPPH free radical scavenging activity of Maejakgwa significantly increased with increasing Cedrela sinensis powder (P<0.001), while the pH of the dough, L values and b values of Maejakgwa significantly decreased with increasing Cedrela sinensis powder content (P<0.001). The consumer acceptability score for 10% Cedrela sinensis Maejakgwa ranked significantly higher (P<0.001) than those of the other groups in overall preference, flavor, taste, crispiness and color. From these results, we suggest that Cedrela sinensis is a good ingredient for increasing the consumer acceptability and functionality of Maejakgwa.
