붉은 양배추와 마늘종 추출물의 항산화 및 항균활성 평가와 냉장저장 중 돈육패티에 이용

This study was carried out to investigate antioxidative and antimicrobial activities of ethanol extracted garlic stem and red cabbage, and their application to pork patties during refrigerated storage. Total phenolic compounds of ethanol extracted garlic stem and red cabbage were 3.13 g/100 g and 3.99 g/100 g, respectively. 1,1`-diphenyl-2-picryhdrazyl (DPPH) radical scavenging activity of garlic stem extracts increased up to 0.05%. Iron chelating activities of both garlic stem and red cabbage increased up to 0.5%, and red cabbage up to the concentration of 1% had similar iron chelating activity to those of EDTA. Pork patties containing garlic stem had higher Hunter L and b values, (p＜0.05), whereas those with red cabbage had highest Hunter a values, resulting in similar value to those of control (p＞0.05). Thiobarbituric acid reactive substances (TBARS) of pork patties with garlic stem were lower than those of the control (p
