Quercetin has antioxidant, anti-inflammatory, antiproliferative and anticarcinogenic properties. In plant foods, quercetin occurs mainly bound to various sugars via a beta-glycosidic link. We hypothesized that lactase phlorizin hydrolase (LPH), an enzyme at the brush border membrane of intestinal cells, is
