Abstract

The objective of this study was to asses the quality characteristics of yanggaeng prepared with different ratios of chestnut powder: 0%, 5%, 10%, 15%, and 20%. The moisture content of the control yanggaeng was higher than that of any other chestnut powder added groups. In terms of color, The lightness (L) and yellowness (b) decreased significantly, but redness (a) increased with increasing contents of chestnut powder. The total polyphenol content and DPPH free radical scavenging activities increased as the amount of chestnut powder. Texture profile analysis showed that the hardness, adhesiveness, cohesiveness, and chewiness were higher than the control group. The result of sensory evaluation test and the overall acceptability showed that the taste, color, flavor, chewiness, softness and overall acceptability were the highest in the 10~15% added group while the color and softness were identified no significant different group. Based on these results, it is suggested that yanggaeng with up 10~15% added chestnut powder can be developed as products.

본 연구에서는 밤을 건조하여 분쇄한 분말을 첨가하여 제조한 양갱의 물리적인 특성과 항산화 활성, 관능검사를 실시하여 제품 특성을 분석하였다. 밤 분말을 첨가하지 않은 양갱의 수분 함량은 35.10%이었으나, 밤 분말의 첨가량이 증가함에 따라 39.24~45.24%로 점차 증가하였다. 밤 양갱의 색도측정에서 명도(L)와 황색도(b)는 밤 분말의 첨가량이 증가할수록 감소한 반면, 적색도(a)는 증가하였다. 총 페놀 화합물 및 항산화 활성은 밤 분말 첨가량이 증가할수록 총 페놀함량과 DPPH free radical 소거능은 유의적으로 증가하였다. 기계적인 조직감은 밤 분말을 첨가할수록 경도, 부착성, 응집성, 씹힘성은 증가하였으나, 탄력성과 끈적임성은 감소하였다. 밤 분말을 첨가한 양갱의 전체적인 기호도는 맛, 색, 향, 씹힘성, 부드러운 정도, 전체적인 기호도는 밤 분말 10% 첨가군에서 가장 높게 나타났다. 이상의 결과로 볼 때 양갱에서 밤 분말 첨가는 10~15%가 가장 적당할 것으로 사료되며, 기능성 가공 식품의 제품 개발 및 연구에 밤의 활용도를 높여 가공식품의 시장에 도입하면 밤 생산 및 밤을 이용한 상품개발에 바람직하며, 밤을 대량 생산하는 공주 지역 발전에도 도움이 될 것으로 사료된다.
