Abstract

본 연구는 아사이베리 분말을 첨가한 양갱의 품질특성과 항산화 효과의 측정 및 관능평가를 실시하였다. 아사이베리 분말을 첨가한 양갱의 수분함량은 아사이베리 분말 첨가비율의 증가에 따라 높아졌다. pH와 당도는 아사이베리 분말의 첨가비율이 높아질수록 낮아졌다. 색도는 아사이베리 분말의 첨가비율이 높아질수록 L값과 b값은 낮아졌고, a값은 높아졌다. 조직감은 아사이베리 분말의 첨가비율이 높아질수록 경도, 검성, 응집성, 씹힘성이 낮아졌고, 탄력성은 유의성이 나타나지 않았다. 아사이베리 분말 첨가 양갱의 총 페놀성 화합물 함량과 DPPH 라디컬 소거능은 아사이베리 분말의 첨가비율의 증가에 따라 유의적으로 높아졌다. 아사이베리 분말 첨가 양갱의 관능평가 결과는 아사이베리 분말 4% 첨가구가 맛과 전반적인 기호도에서 우수한 기호도를 나타내었고, 다른 관능 기호도 항목에서도 비교적 양호한 점수를 나타내었다. 이상의 결과들을 고려하였을 때, 양갱의 제조 시에 아사이베리 분말을 첨가하는 것은 양갱의 항산화 효과와 관능 기호도 상승효과를 꾀할 수 있을 것으로 판단되며, 백앙금량 대비 4%의 아사이베리 분말을 첨가하는 것이 항산화 효과 및 관능 기호도 측면에서 가장 적합할 것으로 판단된다.

The quality characteristics of Yanggaeng with 0%, 2%, 4%, 6%, and 8% acaiberry (Euterpe oleracea Mart.) powder added were analyzed for physicochemical, antioxidant effects, and sensory preferences. The moisture contents of the Yanggaeng added with acaiberry powder were significantly(p<0.001) increased as the acaiberry powder levels (0%, 2%, 4%, 6%, and 8%) increased. The pH and $^{\circ}brix$ values of Yanggaeng added with acaiberry powder were significantly reduced as the acaiberry powder levels(0%, 2%, 4%, 6%, and 8%) increased (p<0.001). According to the hunter color of Yanggaeng added with acaiberry powder, the L-value(lightness) and the b-value(yellowness) significantly decreased(p<0.001), whereas the a-value(redness) increased as the acaiberry powder levels increased(p<0.001). For the textural characteristics, the addition of acaiberry powder decreased the hardness(p<0.001), gumminess(p<0.001), cohesiveness(p<0.05), and chewiness(p< 0.01), whereas springiness not significantly changed. The total polyphenol contents and DPPH radical scavenging activities were significantly increased aciberry powder(p<0.01, p<0.001). In sensory evaluation, Yanggaeng addition with 4% acaiberry powder had excellent scores in taste and overall sensory preference. These results suggest that acaiberry powder may be a useful ingredient in Yanggaeng for the improvement of sensory preference and antioxidant potential. Considering both the functional and sensory preference aspects of the acaiberry Yanggaeng, the 4% acaiberry powder dosage level can be considered ideal.
