|
|
FIELD: vegetable raw technology. SUBSTANCE: invention relates to a method for isolating pectin from vegetable raw. Method for preparing pectin from citrus husks involves hydrolysis-extraction of a solid phase and separation of a liquid phase. Before hydrolysis-extraction a solid phase is extracted with dimethylformamide and liquid acetylene successively under the above atmosphere pressure. The second extract is separated without pressure change followed by abrupt dropping pressure over a solid phase up to atmosphere value and feeding a solid phase to hydrolysis-extraction. Invention provides reducing loss of pectin being without deterioration of its organoleptic properties. EFFECT: improved preparing method.

| Method for manufacturing carbohydrate-containing gelling concentrate for confectionary products / 2246858 The suggested concentrate should be prepared due to pressing the juice out of sugar beet prepared with deodorated carbon dioxide in supracritical state. Residues should undergo hydrolysis-extracting with hydrochloric acid solution obtained directly in the mentioned process at separate supply of water and liquid hydrogen chloride for this stage. Obtained extract without residues should be mixed with sugar beet juice and supplement the blend with liquid ammonia along with an extract obtained due to extracting Mortierella globulifera micromycete biomass. The blend should be concentrated due to vacuum evaporation. The concentrate should be treated with liquid carbon dioxide and supplemented with a solid residue obtained as a result of extracting the biomass of the mentioned micromycete and treated with liquid ammonia. The mixture should be heated up to 60 C, not less. The innovation provides increased output of the target product and improved structure=-forming properties. |
| Method for preparing pectin substance / 2244441 Invention relates to a method for preparing biologically active substances from medicinal vegetable raw, in particular, to preparing pectin substances from wild strawberry leaves (Fragaria vesca L.). Raw is extracted preliminary with hot water at heating to 95oC in the ratio raw : extractant = 1:10 for 1 h to separate water-soluble polysaccharides followed by filtration off. Raw residue is extracted with mixture of 0.5% oxalic acid solution and ammonium oxalate (1:1) in the ratio = 1:20 at 80-85oC for 1 h. The repeated extracted is carried out twice. The vegetable material is separated by filtration and combined extracts are evaporated. Pectin substances are precipitated with 5-fold amount of 96% ethyl alcohol at room temperature. The precipitated dense deposit is filtered off, washed out with 96% ethyl alcohol and dried. Method provides elevating yield of the end product up to 12.5% of vegetable raw mass of wild strawberry leaves. |
