ABSTRACT
Poland with production of clear apple juice concentrates up to 200,000 tons processes yearly more than 1.5 mln t. of apples. Commercial technologies of processing are very effective but 12 to 20% of processed raw material remains as a waste product after juicing. Typically such material containing sugars, acids and traces of proteins is utilized for animal feeding or composted. Pomace after juice production still contains significant amount of valuable compounds beneficial for human health; polyphenolics and fiber. The content of dietary fiber constitutes is on the average 50% of dry weight. In this study, it was proved that pomace from modern juice production plant contained 60-64% of TDF, 1850-2550 mg/kg dm of flavan-3-ols and 7000 mg/kg dm of polyphenols (with Folin-Ciocalteau method). It was proved that such a raw material is useful for the preparation of liquid and solid phenolic concentrates containing 2.5 and 33% of polyphenols, respectively. Such extracts may be considered as an excellent components for the production of new more healthy and valuable products.
