Abstract

Lipid oxidation and antioxidant stabilities of nut-sesame yeotgangjeong (Korean traditional candy bar) with different binders were evaluated during storage in the dark. S1, S2, and S3 binders consisted of starch syrup, sugar, and water (58:34:7.6, w/w/w); starch syrup, jocheong, honey, trehalose, and water (43.5:11.6:2.9:34:7.6, w/w/w/w/w); and starch syrup, jocheong, honey, sugar, trehalose, and water (43.5:11.6:2.9:17:17:7.6, w/w/w/w/w/w); respectively. Lipid oxidation was determined by peroxide and p-anisidine values, and tocopherol, lignan, and polyphenol contents were determined spectrophotometrically. Peroxide values were significantly higher (p<0.05) in yeotgangjeong samples with S2 or S3 binder than in those with S1; however, the converse was true for tocopherol degradation. Lignan was the most stable antioxidant in yeotgangjeong. The results suggest that tocopherols have a priority over lignans to control the lipid oxidation of yeotgangjeong during storage; reduced lipid oxidative stability after substituting sugar with trehalose might be because it increases oxygen diffusivity and inhibits the antioxidant action of tocopherols on lipids.

결착제의 조성을 달리하여 제조한 견과-깨 엿강정의 저장 중 지방질 산화 정도와 산화방지제 함량을 평가하였다. 엿강정 제조시 결착제를 물엿 대신 꿀, 조청, 그리고 설탕 대신 트레할로스로 전부 또는 일부 대체하였을 때 엿강정의 저장 중 지방질 산화가 증가, 가속되었으며 트레할로스에 의한 산소 퍼짐도 증가가 일부 기여했을 가능성이 있다. 또한 엿강정을 저장하였을때 산화방지제 중 리그난의 안정성이 가장 높았으며, 토코페롤 분해속도는 설탕을 트레할로스로 대체한 엿강정에서 낮아 트레할로스가 토코페롤의 지방질 산화방지작용을 억제한 가능성을 제시하였다.
