Development of new plant extracts rich in hop polyphenols
نویسنده
چکیده
Investigations were started to develop methods for isolating beneficial polyphenols from hops. As a result two new types of extracts were developed. One is mainly consisting of prenylflavonoids (main ingredient is xanthohumol). This product is not soluble in water but in ethanol. The other extract is water soluble and rich in glycosidically bound polyphenols (multifidol, quercetin, kaempferol). Each of both hop products could constitute an innovative ingredient of functional food or food supplements. A non-alcoholic mixed beverage containing an extract rich in xanthohumol is already on the market. To overcome its water insolubility a food grade emulsifier is added.
