Effects of dandelion addition on antioxidant property, sensory characteristics and inhibitory activity against xanthine oxidase of beer.

ABSTRACT: The effects of dandelion addition (DA) on the physiochemical properties, antioxidant activity, inhibitory activity against xanthine oxidase (XOD) and flavor of craft beer were investigated. It was found that DA changed the pH value, total acid content, thiobarbituric-acid-value, sugar content and color of beer, and increased the contents of total polyphenols and flavonoids and thus the antioxidant activity of beer. HPLC analysis showed that DA provided beer with chlorogenic, caffeic, ferulic, and chicoric acid, contributing to the inhibition activity against XOD that is a key enzyme in uric acid production. GC-MS analysis showed that 3-methyl-1-butanol, isopentyl acetate and ethyl caprylate were main aroma components of all samples. Although DA introduced the special aroma component of azu
