본 연구는 유과의 저장안전성 및 관능적 품질개선을 위한 연구의 일환으로 가루녹차를 첨가하여 유과를 제조한 후 품질특성을 비교 평가하고 최종적으로 가루녹차 첨가 유과의 품질 및 저장성 증진에 미치는 영향을 평가하고자 실시하였다. 그 결과 가루녹차 1, 2, 3% 첨가량에 따른 수분 함량은 변화가 없었으며, 조지방 함량은 첨가량이 증가할수록 유의적으로 낮아지는 것으로 나타났다. 가루녹차 첨가 유과의 기공크기와 팽화율은 가루녹차 첨가량이 증가할수록 감
This study investigated the effects of green tea powder (GTP) on the quality characteristics of Yukwa during storage, to improve shelf-stability and sensory quality. The crude lipid contents of Yukwa decreased with increasing levels of GTP, but significant changes in moisture contents were not found. 'The blowhole size and expansion rate of Yukwa decreased with increases in GTP. The hardness of Yukwa samples with over 2% (w/v) GTP significantly increased, but no notable changes in hardness during storage were found. Sensory evaluation tests indicated that all sensory characteristics decreased with increasing GTP levels, but there was no significant difference in overall acceptability between Yukwa samples with 1% (w/v) GTP and control. Antioxidant activity increased as the concentration of GTP increased 'The results indicate that addition of 1% (w/v) G1P yielded optimal quality of Yukwa during storage.
