본 연구는 옥수수 수염 추출액과 흑미를 이용한 식혜를 제조하였다. 옥수수 수염 추출액/흑미 식혜(CSE/BR-SH)의 당화 과정 중 pH는 초기 pH 에서 당화 1시간째 5.92로 약가 증간 후 서서히 감소하여 당화 종기(6시간째) 로 나타났다. 반면에 brix 당도와 환원당은 각각 초기 brix와 g/L에서 당화 6시간째 각각 brix와 로 증가하였다. 한편 당화 초기 95.23%에서 당화 1시간되는 시점에 최대 활성인 116.12%를

We prepared sikhe (CSE/BR-SH) using corn silk extract and black rice. The pH decreased during saccharification, from pH to pH after 6 h. However, the brix and reducing sugar contents increased during saccharification of CSE/BR-SH, with the highest levels ( brix and g/l, respectively) being attained at 6 h. Amylase activity increased to 116.12% of control values 1 h after saccharification of CSE/BR-SH, and decreased thereafter. CSE/BR-SH was light purple in color. Soluble phenolic concentration increased markedly from an initial 8.43 g/l to 23.09 g/l at the end of saccharification (6 h), as did DPPH radical-scavenging activity (from an initial 17.3% to 70.98%), Increases were noted in all of ABTS radical-scavenging activity (from 40.25% to 75.32%), reducing power (from 0.241 to 0.682), and ferric reducing antioxidant power (FRAP) (from 0.288 to 1.071).
