Process for producing raw beta-glucan from oyster cap mushroom (pleurotus oestratus) sporocarps or from a substrate for culturing the oyster cap mushroom

摘要

the essence of the problem is that the solution na.sub.2.n.co.sub.3.n.a nahco.sub.3.n.pripravu00ed buffer with ph value of 9.5 to 10.0 to start over at a temperature at least 58.degree.c, to the solution primu00edchaju00ed crushed part plodnic hlu00edvy u00fastricnu00e9 mushrooms (pleurotus oestratus) and / or the substrate for pestovu00e1nu00ed hlu00edvy u00fastricnu00e9 prorostlu00e9ho mycelium fungus of mushroomwhile the fraction primu00edchanu00fdch part lies in the range from 5 mm to 10 mm, a buffer, and primu00edchanu00fdch part has a dry matter content in the range of from 5 to 8%, and extracted with stirringnaceu017e to separate filtrate, start over, figure below is neutralised and cool, odstrenu00ed is vysru00e1u017eenu00e9 proteinsto kapaline after odstredenu00ed is pridu00e1 the same volume of 2-propanol zchlazenu00e9ho temperature 2 to 4.degree.c, smes are mixed and odstredu00ed with compressed raw. beta. - glukan. odstredenu00fd. beta.glucan is dissolved in distilled water and with the advantage of ultrasound desintegru00e1torem at temperature 90 to 100.degree.c disperguje colloidal solution.
