Problems solved by technology

However, fenugreek gum made by traditional methods is easy to agglomerate in water, difficult to disperse and takes a long time to dissolve, so it cannot be directly applied to industries such as health food and medicine

Embodiment 1

[0026] In a beaker, 200g of high-quality fenugreek film was fully mixed with 220g of water (water temperature 40° C.) and stirred for 20 minutes. It is then flaked, dried and comminuted using laboratory equipment. The sieving method selects the material with a particle size of 120 to 180 mesh and impregnates it with 85% edible alcohol (solvent ratio is 1:3), and the impregnation treatment time is 3 hours, then centrifuges and precipitates, and vacuum-dries at 70°C with a vacuum degree of 0.092Mpa 2 hours.

[0027] The sample prepared by the above method was compared with the commercially available fenugreek gum for water dispersibility, dissolution rate and 1% glue viscosity. The result shows: sample can disperse rapidly (dispersion time-1 ), commercially available fenugreek gum is easy to agglomerate in water, and it takes about 3 hours to completely dissolve and reach the maximum viscosity under strong stirring, and the viscosity value of 1% glue is 210mPa.s (170s -1 ). C...

Embodiment 2

[0029] In a beaker, 200 g of high-quality guar gum flakes were fully mixed with 300 g of water (water temperature 45° C.) and stirred for 60 minutes. It is then flaked, dried and comminuted using laboratory equipment. The sieving method selects the material with a particle size of 120 to 200 mesh and impregnates it with 65% edible alcohol (solvent ratio is 1:6), and the impregnation treatment time is 0.5 hours, then centrifuges and precipitates, and vacuum-dries under 55°C and a vacuum degree of 0.095Mpa 4 hours.

[0030] The samples prepared by the above method were compared with commercially available guar gum for water dispersibility, dissolution rate and 1% glue viscosity. The results show that: the sample can be quickly dispersed in water (dispersion time-1 ), commercially available guar gum is easy to agglomerate in water, and it takes about 3 hours to completely dissolve and reach the maximum viscosity under strong stirring, and the viscosity value of 1% glue is 253mPa...

Embodiment 3

[0032] In a beaker, 200 g of high-quality saponins and 140 g of water (water temperature 20° C.) were fully mixed and stirred for 40 minutes. It is then flaked, dried and comminuted using laboratory equipment. The sieving method selects the material with a particle size of 120 to 240 mesh and impregnates it with 95% edible alcohol (solvent ratio is 1:1). The impregnation treatment time is 6 hours, then centrifugal precipitation, and vacuum drying at 75°C and vacuum degree of 0.07Mpa 3 hours.

[0033] The samples prepared by the above method were compared with the commercially available saponin gum in water dispersibility, dissolution rate and 1% glue viscosity. The result shows: sample can disperse rapidly (dispersion time-1 ), commercially available acacia gum is easy to agglomerate in water, and it takes about 3 hours to completely dissolve and reach the maximum viscosity under strong stirring, and the viscosity value of 1% glue is 265mPa.s (170s -1 ). Compared with comme...

Abstract

A fast-dispersing quick-dissolving galactomannan gum is prepared from high-quality industrial-class galactomannan gum chips through hydrating while continuous stirring, airflow drying, pulverizing by at least 100 meshes, classifying by 100-240 meshes, impregnating in 65-95% edible alcohol, centrifugal desolvation, and vacuum drying.

Description

technical field [0001] The invention relates to a production method of galactomannan gum. Background technique [0002] Galactomannan gum is a polysaccharide gum isolated and extracted from plant seeds such as fenugreek, guar, acacia, wild acacia, Tara and tianjing. Its structure is composed of D-mannose through β-1,4 glycosides Links form the main chain, and D-galactose and D-mannose form side chains through α-1,6 glycosidic bonds to form multi-branched glycans. Galactomannan gum has good cross-linking properties and can form a stable aqueous solution with high viscosity at low concentration. Therefore, it is widely used as a thickener, stabilizer, adhesive, etc. in petroleum drilling, textile printing and dyeing, mining ore dressing, military explosives, daily chemical ceramics, wood processing, papermaking and other industries. The production of galactomannan gum is first to separate the endosperm sheet (also called film in industry) from the seed by physical method, an...
