Brewing of a Porter Craft Beer Enriched with the Plant <i>Parastrephia lucida</i>: A Promising Source of Antioxidant Compounds

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.
