Abstract Beer is a fermented beverage rich in polyphenols, with approximately 30% derived from hops and 70–80% originating from the malt. In a previous study, a native plant called Parastrephia lucida was reported as a new natural source of antioxidant compounds. Thus, this study aimed to produce a Porter-style craft beer enriched with P. lucida, for a higher antioxidant capacity. The addition of P. lucida was shown to increase linearly relative to the concentration of bioactive compounds and antioxidant activity compared with the control beer. In conclusion, an enriched Porter-style beer was brewed with a native plant, as a source of bioactive compounds, which allowed for the production of a beer with high antioxidant activity, while maintaining the characteristics of the beer.

酿造富含植物 Parasrephia lucida 的波特精酿啤酒：抗氧化化合物的有希望的来源

摘要 啤酒是一种富含多酚的发酵饮料，其中约 30% 来自啤酒花，70-80% 来自麦芽。在之前的一项研究中，一种名为 Parasrephia lucida 的本地植物被报道为抗氧化化合物的新天然来源。因此，本研究旨在生产一种富含 P. lucida 的波特式精酿啤酒，以提高抗氧化能力。与对照啤酒相比，P. lucida 的添加显示出相对于生物活性化合物的浓度和抗氧化活性呈线性增加。总之，一种浓缩的波特式啤酒是用一种本地植物酿造的，作为生物活性化合物的来源，这使得生产具有高抗氧化活性的啤酒，同时保持了啤酒的特性。
