Abstract

The ground red pepper puree was treated with cellulase (C treatment), pectinase (P treatment), amylase (A treatment) and/or enzyme complex (CP, CA, PA and CPA treatment) for 2~8 hours to improve the yield and bioactivity of extracts. And physicochemical and sensory properties of red pepper extracts were evaluated. The extraction yield of the control was 38.84%, which was lower than those of the enzyme treatments. And extraction yields of enzyme complex treatments were higher than that of single enzyme treatments. Especially, extraction yield was increased to 74.37% by cellulase + pectinase + amylase complex treatment (CPA treatment). The soluble solid and reducing sugar contents were higher in the extracts treated with enzymes compared with the control. CA and CPA treatment showed the highest soluble solid and reducing sugar contents. No significant changes in lightness, redness and yellowness of the control and the samples by enzyme treatments were observed during 2~8 hours experiments. The sensory evaluation results revealed that panelists preferred the extracts with enzyme treatments to the control. Therefore, enzyme treatment for red pepper extracts is a good method to improve the yield and sensory properties.

고추 추출액의 수율 및 생리적 기능성을 향상시키기 위하여 고추에 cellulase(C 처리군), pectinase(P 처리군), amylase(A 처리군)를 각각 또는 이들 효소들을 혼합(CP, CA, PA 및 CPA 처리군) 첨가하여 2~8시간동안 가수분해시킨 후 가열처리하고, 여과시킨 추출액에 대하여 이화학적 및 관능적 평가를 측정하였다. 효소 처리 고추 추출액의 수율은 효소 처리를 하지 않았을 때 38.84% 정도로 매우 낮게 나타났지만, 효소처리군이 높은 수율을 보였고, 효소 단독처리군보다는 병용처리 시 수율이 증가하였으며, 효소 처리 시간이 길어질수록 유의적으로 수율이 증가하는 것으로 나타났다. 특히 cellulase + pectinase + amylase(CPA) 복합처리군은 추출수율이 74.37%까지 증가하였다. 가용성 고형분의 함량변화는 대조군의 경우에는 8.51% 를 나타내었으나, 효소처리군은 대조군보다 높은 함량을 나타내었으며, CA 혼합처리군과 CPA 혼합처리군이 가장 높은 가용성 고형분 함량을 보였다. 환원당의 함량 또한 효소 처리에 의하여 증가하는 것으로 나타났다. 효소 처리에 의한 색도의 변화에서는 대조군과 효소처리군 간에 색도의 변화를 보이지는 않았다. 효소 처리한 고추 추출액에 대한 관능검사 결과에서는 전반적으로 효소 처리를 하지 않은 대조군에 비하여 효소 처리 시 기호도 면에서 우수한 것으로 나타나, 고추 추출물 제조를 위한 효소 처리는 수율 및 기호도 증진을 위한 좋은 방법으로 사료된다.
