In this research, the Aronia melanocarpa pomace polyphenols (AMPPs) were extracted and purified. The purified AMPPs contained the most abundant chlorogenic acid (CGA) at 36.91 mg/100 mg, followed by chrysin at 8.61 mg/100 mg. At a concentration of 60 μg/mL, the purified AMPPs exhibited stronger scavenging activity against: DPPH radical, hydroxyl radical, ABTS∙, and also showed greater Fe reducing activity than the V control group. To solve the problem of easy spoilage of chilled meat during storage, gelatin edible coatings containing Aronia melanocarpa pomace polyphenols, referred to as G/AMPPs, were investigated for their effect on the chilled storage of pork. At a 1:1 volume ratio of 1 % polyphenol solution to 3 % gelatin solution, the G/AMPPs coating effectively curbed pH, TVB-N, TVC, drip loss, and b* value increases in chilled pork, while delaying declines in hardness, adhesion, a* value and L* value; The TVB-N content and TVC values demonstrated that the G/AMPPs coating significantly extended the shelf life of chilled pork by up to 15 days. The results showed that G/AMPPs had good preservative, antibacterial and antioxidant effects on chilled pork and thus development of G/AMPPs based coating shows appeared to offer promise for meat preservation.
在这项研究中，从黑果腺肋花楸废渣中提取并纯化了多酚。纯化后的黑果腺肋花楸多酚（AMPPs）含有最丰富的绿原酸（CGA），为 36.91mg/100mg，其次是白杨素，为 8.61mg/100mg。在 60μg/mL 浓度下，纯化的 AMPPs 对 DPPH 自由基、羟基自由基、ABTS·表现出更强的清除活性，并且其铁还原活性也比 V 对照组强。为了解决冷藏肉在储存过程中容易变质的问题，研究了含有黑果腺肋花楸废渣多酚的明胶可食用涂层，称为 G/AMPPs，以研究其对冷藏猪肉的影响。在多酚溶液与明胶溶液体积比为 1:1 的 1%浓度下，G/AMPPs 涂层有效抑制了冷藏猪肉 pH 值、TVB-N、TVC、滴水损失和 b值的增加，同时延缓了硬度、附着力、a值和 L*值的下降；TVB-N 含量和 TVC 值表明，G/AMPPs 涂层可将冷藏猪肉的货架期延长多达 15 天。结果表明，G/AMPPs 对冷藏猪肉具有良好的保鲜、抗菌和抗氧化作用，因此基于 G/AMPPs 的涂层的开发似乎为肉类保鲜提供了希望。
