In this study, fresh pork was used as raw material to make minced pork, then Purslane extract (PE) with different concentrations (0.2, 0.4, 0.8 g/kg) was added, and 0.8 g/kg of butyl hydroxyanisole was used as positive control and blank control was set at the same time. The changes in thiobarbituric acid value (thiobarbituric acid reactive substances, TBARs), carbonyl content, total sulfhydryl content, surface hydrophobicity, color, and texture characteristics of minced pork during cold storage (1, 3, 5, 7, 9 days) were studied, and the effects of PE on fat, protein and quality of minced pork during cold storage were evaluated. The results showed that 0.8 g/kg purslane extract could significantly reduce the increase of TBARs, surface hydrophobicity and carbonyl group (P＜0.05). The 0.4 g/kg purslane extract could effectively reduce the decrease of the total sulfhydryl group (P＜0.05), and there was no significant difference between the three concentrations at the later stage of storage (P>0.05). The 0.2 g/kg purslane extract could significantly reduce a* decrease and hardness increase (P＜0.05). The extract of portulaca oleracea also reduced meat cohesion and L* value (P＜0.05), but it had little effect on b* value, chewiness and elasticity. Therefore, three concentrations of PE could inhibit the oxidation of fat and protein to a certain extent, improve the quality characteristics of minced pork, and show a certain concentration dependence on TBARs value, carbonyl group and surface hydrophobicity.
