摘要:

目的:对不同来源(猪皮、牛皮、驴皮、鳕鱼皮、牛骨)胶原肽的抗氧化活性和吸湿保湿性能进行比较研究。方法:采用清除 DPPH 自由基和 ABTS+·及还原力测定进行胶原肽抗氧化活性的评价,同时对胶原肽的吸湿性和保湿性进行比较分析。结果:驴皮胶原肽具有较强的清除DPPH 自由基的能力,IC50 值为0.63mg/mL。鳕鱼皮胶原肽具有较强的清除ABTS+·的能力,IC50 值为0.12mg/mL。驴皮胶原肽具有较强的还原力,在质量浓度10mg/mL 时,OD700nm 值为0.61。驴皮胶原肽具有较好的吸湿保湿性,在相对湿度43% 的环境下,24h,吸湿率10.17%、72h,保湿率98.90%。结论:驴皮胶原肽具有很好的抗氧化性和吸湿保湿性。

Abstract:

Objective: To explore the antioxidant activity, moisture-absorbing and moisture-retention properties of collagen peptides from different sources. Methods: The antioxidant activities of collagen peptides from different sources were evaluated by determining their scavenging activities on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azino-bis-2-ethybenz-thiazoline-6-sulfonic acid (ABTS+) free radicals and their reducing power. Results: The collagen peptide from donkey revealed the strongest scavenging activity on DPPH free radicals with IC50 of 0.63 mg/mL. The collagen peptide from Alaska pollack skin exhibited stronger scavenging activity on ABTS+ free radicals with an IC50 of 0.12 mg/mL. Meanwhile, the collagen peptide from donkey also exhibited the strongest reducing power, which was 0.61 at the concentration of 10 mg/mL. The moisture-absorbing and moisture-retention rates of collagen peptide from donkey were 10.17% and 98.90% under the relative humidity of 43%. Conclusion: The collagen peptide from donkey can be used as a good additive in functional food and cosmetics.

Key words: collagen peptide, antioxidant activity, moisture-absorbing property, moisture-retention property
