(54) METHOD FOR OBTAINING POLYSACCHARIDES OWNED BY EMULSING PROPERTIES

poking through a double layer of gauze and filtering GNGb) Gmagu. The filtrate is concentrated by evaporation in vacuum at 70 ° C until the specific gravity of the extract is 1.06. A sample of the extract is taken of 5 ml and the alcohol number of the extract is determined by titration with 96 ° ethanol (1: 5) and the product PS precipitates - sediment-coagulant cooled (5: 5 ° C) with 96 ° ethanol in an ratio equal to / 2 alcohol number (1: 2.5). Blend || incubate for 3-6 hours and the PS product is separated by filtering over canvas with a cloth or filter paper and dried at 50-60 ° C until the moisture content is no more than 10%. The PS product is a light-gray powder of a polysaccharide nature, yield 7–8%, emulsifying activity ± 10., Foaming capacity E, 3-4 ml / ml:

The mother liquor filtrate from the PS AHVTCHHH product is concentrated in a vacuum by evaporation and dried at a temperature of 60 - TOC.

The product of SF (dried filtrate) 1a) - hygroscopic brown color powder., Yield 7-10 / o. S: - 120 m 2 / g ± 9; Eio 2.5 - 3.3 ml / ml. . Example 2. Take 5 kg of herb clover volzuchey (Trifolium repense L), from the concentrated extract (sp. Weight 1.06) precipitated product PS 96 ° 7th ethanol in a ratio equal to the alcohol number

(1: 5) and then proceed as indicated in

example 1. The product yield PS 6-7%,

S 100m2 / g ± 7, Edo 1.0-1.5 ml / ml;

The output of the product of the SF 10: -16% .i

Example 3. Take 5 kg of grass clover plow (Trifoliae arvense L) and then proceed as indicated in example 2. The product yield PS 5 - 6%, S 88, E, 2.1 - 2.5 ml / ml.

The product yield SF 8 - 10% .;

Example 4. Take 5 kg of grass spine: multi-leaf (Anthvllis polvphilla Wj, the extract is concentrated in vacuo to a specific weight of 1.038-1.042. From the extract, product PS is precipitated (fraction a) with 96 ° ethyl alcohol in a ratio equal to the alcohol number (1: 6 ) and then proceed. as indicated in example I. The yield of the product PS: (fraction a) 3 - 4%, Sx, 137 ± 10, E / lo 3.7 - 4 ml / ml.

If the PS product is precipitated from the extract

(fraction b), then 96 ° ethyl alcohol is poured in a ratio of 2/3 - 3/4 of the alcohol number (1: 4-1: 4.5) and then proceed as indicated in Example I.

. The product yield PS (fraction b) 4 - 8% 25. The product yield SF 7-10%, 5., and 8m2 / g ± 10.

The table shows the surface-active properties of the resulting polysaccharides products PS and SF.

The proposed method provides for obtaining target products with high emulsifying activity - 88- 99 m / g PS and SF - 120-147, as compared with the known -51.1.
