为探讨花生肽亚铁在模拟人胃肠仿生消化条件下抗氧化活性变化规律,研究了仿生消化过程中表面疏水性、DPPH·清除率、O_2~- ·清除率、·OH清除率、亚油酸氧化抑制活性和脂质过氧化抑制活性等指标变化。结果发现:模拟胃肠仿生消化后花生肽亚铁表面疏水性得到增强,仿生消化270 min时表面疏水性最大((15.84 ± 0.33)μg);仿生消化增强了DPPH·清除活性,仿生消化300 min时,DPPH·清除率为(88.77 ± 1.00)%,显著高于1.0 mg /mL V_C(p < 0.05);胃肠仿生消化物O_2~- ·和·OH清除活性分别显著低于1.0 mg /mL V_C和0.6 mg /mL V_C;胃肠仿生消化物具有较好的亚油酸氧化抑制作用,小肠仿生消化物抑制活性最...

To investigate the changing rule of antioxidant activity of peanut peptide-ferrous(PPF)during simulated human gastrointestinal digestion(SHGD),the surface hydrophobicity,DPPH·scavenging rate,O_2~- ·scavenging rate,·OH scavenging rate,linoleic acid oxidation inhibitory activity and lipid peroxidation inhibitory activity of PPF during SHGD were studied.The results showed that SHGD enhanced the surface hydrophobicity,and the surface hydrophobicity of(15.84 ± 0.33)μg was the highest at 270 min.SHGD enhanced the DPPH·scavenging capacity,the DP...
