FIELD: vegetable raw technology. ^ SUBSTANCE: invention relates to a method for isolating pectin from vegetable raw. Method for preparing pectin involves milling and mixing sunflower heads and citrus husks, hydrolysis-extraction of mixture, separation of a liquid phase and isolation of the end product from its. Citrus husks and sunflower heads are extracted with ethyl acetate and liquid acetylene before mixing separately and successively under the above atmosphere pressure. The second extract is separated without pressure change followed by abrupt dropping pressure over a solid phase to atmosphere value and feeding a solid phase to hydrolysis-extraction after mixing. Invention provides enhancing quality of the end product due to elimination of undesirable taste and odor being without deterioration of its technological properties and without reducing the specific yield of pectin. ^ EFFECT: improved preparing method. |
