배즙과 배 건조분말을 이용하여 기능성 양갱을 제조하기 위하여 물대신 배즙을 넣고 배건조분말(열풍, 동결), 백앙금, 한천, 젤라틴, 소금을 첨가하여 배양갱을 제조하였다. 배양갱의 일반성분, 총 폴리페놀 함량, 항산화활성, 색도, 조직감, 관능평가를 실시한 결과는 다음과 같았다. 물을 이용한 C양갱의 수분함량은 27.9%로 가장 많았고 열량과 탄수화물 함량은 가장 적었으며, 배즙 양갱(PJ)과 배즙과 배 열풍건조분말 양갱(PJH), 배즙과 배 동결
This study was conducted to investigate the physicochemical characteristics of yanggaeng prepared with pear juice and dried pear powder. The proximate composition and total polyphenol content, antioxidant activities, Hunter's color values, texture, sensory properties of pear yanggaeng variants [pear juice (PJ), pear juice and hot-air-dried pear powder (PJH), pear juice and freeze-dried pear powder (PJF) yanggaeng] were examined. The moisture content was highest (27.9%) in the control (C) yanggaeng, but the latter's energy and carbohydrate content were lower than in the pear yanggaeng variants. The differences between the pear yanggaeng variants were not significant.The total polyphenol content was highest in the 20.7 mg/100g PJF yanggaeng. The antioxidant activities of PJF yanggaeng were higher than those of the other pear yanggaeng varients. The Hunter color value results showed that the lightness (L) values were highest in C yanggaeng whereas the redness(a) and yellowness(b) values were highest in PJH yanggaeng. The springiness in texture was lowest in C yanggaeng and not significant in the others. The hardness and chewiness were highest in PJH and PJF yanggaeng, but adhesiveness was lowest therein. The results of the sensory test showed that PJF yanggaeng was the highest in flavor, color, taste, hardness, chewiness, and overal quality. Based on these results, it can be concluded that pear juice and freeze-dried pear powder yanggaeng has excellent physicochemical and antioxidant activities.
