초록

염생식물인 함초는 우리나라에서 가능성 있는 기능성 식품소재의 알려져 있다. 본 연구는 돈육 지방에 대한 기능성 식품소재로서의 가능성을 알아보기 위해 실험을 수행하였다. 해안에서 채취한 함초를 부분적으로 잎, 줄기, 뿌리로 구분하여 항산화 효과를 비교하였다. 시료에 대한 항산화 효과는 TBA 방법을 사용하여 살펴보았다. 해안 함초의 경우 동격 건조한 잎(FLC)이 0일째에 BHT 다음으로 낮은 TBARS치를 나타내어 가장 항산화 효과가 좋았다. 그러나 저장 7일에는 온풍 건조한 잎(OLC)과 TBARS치가 큰 차이가 없었다. 저장 14일에는 온풍 건조한 잎(OLC)이 BHT 다음으로 높은 항산화 효과를 나타냈다. 결론적으로 해안에서 채취한 함초는 항산화 효과를 보였으며, 온풍 건조시킨 시료에서 잎 >뿌리 >줄기 순으로 돈육의 지방에 대한 항산화 효과를 나타냈다. 특히, 함초는 천일염(sea salt)과 죽염(bamboo salt)보다 2배이상의 항산화 효과를 보였다.

Classwort (Salicornia herbacea L.), a halophyte, is a potential functional food resource in Korea. This study was conducted to determine the antioxidant activity of glasswort, as a functional food material, on the lipid oxidation of pork. To compare antioxidant effect of different parts of glasswort, samples such as dried ground leaves, stems, and roots of glasswort were prepared. The antioxidant activity was determined by the TBARS(Thiobarbituric Acid Reactive Substances) method. Freeze-dried leaves of glasswort at 0 day of storage had the lowest TBARS values, suggesting the highest antioxidant effect. But the antioxidative effect of freeze-dried leaves of glasswort was less than that of BHT. At 7 days after storage, however, the values were not different from oven-dried leaves. The oven-dried leaves at 14 days after storing should highest antioxidative activity. In conclusion, antioxidative effect of glasswort was apparently exhibited through measurement of TBARS. Antioxidative effect from ground leaf sample of glasswort harvested in coastal region was the highest, followed by root and stem samples. Glasswort had twice as high antioxidative effect as sea salt and bamboo salt.
