상어 collagens(SC)(ASSC: 산가용성 껍질 collagen, ASMC: 산가용성 육 collagen, PSSC: pepsin 가용성 껍질 collagen, PSMC: pepsin 가용성 육 collagen)의 항산화성, 항균성, tyrosinase 및 elstase 저해활성을 표품(시판 marine collagen)과 비교하였다. SC()의 전자공여능은 로 표품의 에 비하여 배가 높았다. SC()의 SOD활성은 4.67로 STMC
The antioxidant and antimicrobial effects of acid-soluble and pepsin-solubilizable shark (Isurus oxyrinchus) collagens (SC) (ASSC: acid-soluble shark skin collagen, ASMC: acid-soluble shark meat collagen, PSSC: pepsin-solubilizable shark skin collagen, PSMC: pepsin-solubilizable shark meat collagen) and standard marine collagen (STMC) as materials, and the ability of these materials to inhibit tyrosinase and elastase, were investigated. The electron-donating ability of SC () was , which was -fold higher than that of STMC at the same concentration. Also, the SOD(superoxide dismutase)-like activity of SC (5.80 mg/mL) was , thus -fold greater than that of STMC. The MIC values of SC against Staphylococcus aureus and Salmonella enteritidis were /disc, which were remarkably lower than that of STMC (/disc). There was no antimicrobial activity against Escherichia coli in STMC, but the MIC against E. coli was /disc for acid-soluble SC and /disc for pepsin-solubilizable SC. The inhibition of tyrosinase by SC (3-5 mg/mL) was , -fold higher than that of STMC (). Also, elastase inhibition by SC (at 1 mg/mL) was , -fold greater than that of STMC. These results indicated that shark collagens may be valuable new functional materials owing to their antioxidant and antimicrobial properties, and because the inhibitory activities against elastase and tyrosinase are better than those of standard marine collagen.
