Abstract
Способ переработки коры деревьев хвойных пород, включающий измельчение, последовательную экстракцию растворителями возрастающей полярности, концентрирование экстракта и выделение целевых фракций липидов и полифенолов, отличающийся тем, что остаток коры подвергают гидролиз - экстракции при температуре 70-75°С; гидромодуле 1-2,0-2,5; в течение 6-7 ч, с последующим концентрированием экстракта методом ультрафильтрации, высаживанием фракции пектиновых веществ алифатическими спиртами, отделением осадка пектинов центрифугированием и сушкой; оставшуюся проэкстрагированную кору используют для производства корокомпостных удобрений.A method of processing the bark of coniferous trees, including grinding, sequential extraction with solvents of increasing polarity, concentrating the extract and isolating the desired fractions of lipids and polyphenols, characterized in that the remainder of the bark is subjected to hydrolysis - extraction at a temperature of 70-75 ° C; hydromodule 1-2.0-2.5; for 6-7 hours, followed by concentration of the extract by ultrafiltration, precipitation of a fraction of pectin substances with aliphatic alcohols, separation of the pectin precipitate by centrifugation and drying; the remaining extracted bark is used for the production of crust fertilizers.
