Are brought in the State registry of grades of Ukraine of 7 grades of hop plant. Biochemical criteria for identification of selection grades fixed. During a storage of hop cones the index of oxidation of a bitter principles considerably grows. At oxidation of a bitter principles in aromatic grades bitterness of a must with hop plant decreases for smaller magnitude, than at utilization of bitter hop plant. Trial brewings on studying influence of separate selection grades and hoparoms - ethanol and carbon dioxide extracts, granules of type 90, an isomer of granules and granules with antioxidants, and also structure of a bitter principles and polyphenols on quality of a must and beer and his physicochemical parameters are lead Product Description popup.authors popup.nrat_date 2020-04-02 Close
