Differences in physicochemical, mineral and nutraceutical properties between regular, light and zero beers

The differences in physicochemical, mineral and nutraceutical properties between regular, light and zero beers were evaluated. The pH, titratable acidity and colour values of all beers were in the range quality criteria of beer industry. On the other hand, zero beer showed the highest content of Ca, Mg, K and Na, light beer obtained the highest content in Cu, Zn and Fe, while Mn was detected only in regular beer. The highest content of total phenols was found in regular beer, followed by zero and light beers, while in total flavonoids, zero beer obtained the highest content, followed by regular and light beers. Considering the in ABTS, DPPH, FRAP and ORAC antioxidant capacity the results were: regular beer > zero beer > light beer.
