Problems solved by technology

Compared with guar beans and fenugreek, acacia seeds are large, with thick and hard seed coats, and the outer layer of seeds has a waxy layer. Even if the seeds are soaked in warm water for 20 hours, the inside of the seeds still does not absorb water, so the endosperm slices are separated It is difficult to make glue

Embodiment 1

[0023] Take by weighing the honey locust seed 10Kg after impurity removal, magnetic separation, be 2450MHz with 1KW microwave drier (WX10S-A, Nanjing Sanle Electric Appliance Factory) heating frequency, after heating 20min, obtain moisture content and be 10%, impurity rate is 1 %, the acacia seeds without iron impurities, then enter the hammer mill to open the slices with a rotating speed of 3700rpm, the distance between the hammer mill blade and the fixed tooth plate is adjusted to 10mm, and the apertures of the first, second and third screening screens are respectively 8, For 12 and 16 mesh, the rotational speed of the pulverizer is 3500rpm when selecting slices, and the rotational speed of the pulverizer is 3300rpm when selecting. Seeds can be separated to obtain endosperm film after sliced, selected, selected and screened. The yield, polysaccharide content, cellulose content and 1% glue viscosity of the endosperm film were measured. The results are shown in Table 1.

Embodiment 2

[0026] Take by weighing the acacia seed 10Kg after impurity removal, magnetic separation, be 2450MHz with 3KW microwave drier (WX10S-A, Nanjing Sanle Electric Appliance Factory) heating frequency, after heating 12min, obtain moisture content and be 8%, impurity rate is 2 %, the acacia seeds without iron impurities, then enter the hammer mill to open the slices with a rotating speed of 3700rpm, the distance between the hammer mill blade and the fixed tooth plate is adjusted to 12mm, and the apertures of the first, second and third screening screens are respectively 8, For 10 and 18 mesh, the speed of the pulverizer is 3600rpm when selecting pieces, and the speed of the pulverizer is 3200rpm when selecting. Seeds can be separated to obtain endosperm film after sliced, selected, selected and screened. The yield, polysaccharide content, cellulose content and 1% glue viscosity of the endosperm film were measured. The results are shown in Table 2.

Embodiment 3

[0029] Take by weighing the acacia seed 10Kg after impurity removal, magnetic separation, be 2450MHz with 4KW microwave dryer (WX10S-A, Nanjing Sanle Electric Appliance Factory) heating frequency, after heating 25min, obtain moisture content and be 6%, impurity rate is 0.5 %, the acacia seeds without iron impurities, then enter the hammer mill to open the slices with a rotating speed of 3500rpm, the distance between the hammer mill blade and the fixed tooth plate is adjusted to 15mm, and the apertures of the first, second and third screening screens are respectively 12, For 16 and 20 mesh, the speed of the pulverizer is 3300rpm when selecting pieces, and the speed of the pulverizer is 3000rpm when selecting. Seeds can be separated to obtain endosperm film after sliced, selected, selected and screened. The yield, polysaccharide content, cellulose content and 1% glue viscosity of the endosperm film were measured. The results are shown in Table 3.

Abstract

The invention discloses a manufacturing method of using microwave method to separate and extract gleditsin polyoses glue. The method eliminates the impurities and selects with magnetism, then uses microwave to preheat, dry, makes the binding force of husk, endosperm and embryo weaken, makes the seed vessel embrittlement, crushes them with breaking machine, then the first screen sizing, breaking machine crushes and selects, then the second screen sizing, concentration and the third screen sizing, and separates out the endosperm film.

Description

technical field [0001] The invention relates to a preparation process for extracting acacia polysaccharide gum, in particular to a preparation process for separating and extracting acacia polysaccharide gum by microwave method. Background technique [0002] Honey locust (Gleditisia sinensis Lam.) is a deciduous tree or small tree of the family Fabaceae. The content of polysaccharide gum in saponin locust seeds is 36-40%. After analysis, the polysaccharide gum of saponin locust belongs to galactomannan type vegetable gum, and its structure is to form the main chain by connecting D-mannose through β-1, 4 glycoside bonds. D- Galactose and D-mannose form side chains through α-1,6 glycoside bonds to form multi-branched glycans. Galactomannan gum has the characteristics of high viscosity in low-concentration aqueous solution, so it is widely used as thickener, stabilizer, adhesive, gelling agent, flotation agent, flocculant, dispersant, etc. in oil drilling, Food and medicine, t...
