Abstract

The natural sources extracted from crab shell Korean tagnrine peel, sesame meals were utilized to investigate the effects of extracts on free radical reaction, lipid oxidation and nitrite scavenging ability. The recovery percentage of extracts from waste resources (crab shell, sesame meal, dry korean tangrine peel) were chitosan 11.6%, crude sesamol 2.2% and ascorbic acid 2.8%, respectively. The antioxidants were tended to have a lower TBARS value than those of control. The nitrite scavenging and electron donating ability of crude sesamol were tended to be the most effective extract among all extracts. However, In case of chitosan, the superoxide dismutase (SOD)-like activity was the most highest, compared to other extracts.

폐자원으로 얻어지는 게껍질, 감귤껍질, 참깨박이 free radical 반응 및 지방산화 억제에 미치는 영향과 nitrosamine 생성의 직접적인 영향인자인 아질산염에 대한 폐자원의 분해 효과를 검토하였다. 폐자원(게껍질, 참깨박, 감귤껍질)으로 부터 유효성분인 chitosan, crude sesamol, ascorbic acid는 각각 11.6%, 2.2%, 2.8%로 나타났으며, TBARS값은 대조구에 비하여 낮은 값을 나타내어 항산화성이 인정되었다. 또한, 전자공여능은 chitosan 29.8%, crude sesamol 35.2%, 감귤껍질 추출물 15.8%로 나타났으며, SOD 유사활성능은 전반적으로 SOD 유사활성이 8% 이상으로 나타났으며, chitosan 51.3%, crude sesamol 19.9%, 감귤껍질 추출물 8.4%로 나타났다. 폐자원 추출물의 nitrite 소거작용은 pH 1.2에서 chitosan 17.4%, crude sesamol 56.4%, 감귤껍질 추출물 19.0%로 나타났으며, crude sesamol이 pH 1.2와 pH 3.0에서 각각 56.4%, 55.4%의 높은 소거작용을 나타내었다.
