Embodiment 1

[0047] Embodiment 1: the preparation method of saponins polysaccharide gum

[0048] 1. Sulfur treatment: Submerge 500g of acacia seeds (9.2% water content, 1.5% impurity content) in 900mL sulfuric acid solution with a volume concentration of 55%, and perform acid treatment in a 60°C water bath for 2 hours;

[0049] 2. Hulling and drying: Rinse the acid-treated acacia seeds with 1500 mL of cold water, and scrub to remove the carbonized seed shells on the outer layer, and dry the shelled seeds in a fluidized bed drying oven at 90°C for 30 minutes;

[0050] 3. Opening: using a hammer mill, the distance between the blade and the fixed tooth plate is 7mm;

[0051] 4. Slice selection and screening: the aperture of the screen for the first screening is 13 mesh, the rotating speed of the pulverizer in the sheet selection section is 3200 rpm, and the aperture of the screen for the second screening is 22 mesh, namely the polysaccharide film;

[0052] 5. Hydrated polysaccharide film: th...

Abstract

The invention relates to a Gleditsia sinensis polysaccharide gum and a preparation method thereof. The preparation method of the Gleditsia sinensis polysaccharide gum comprises the following steps: preprocessing the Gleditsia sinensis seed with sulfuric acid, then shelling, drying, chipping, selecting, screening, hydrating, and grinding. The method prepares the polysaccharide gum by steps of preprocessing the Gleditsia sinensis with sulfuric acid, and separating by washing with water, chipping, and so on, the ratio of galactose to mannose in product is changed while the content of water insoluble matter in product is lowered, so that the polysaccharide gum has better gel property after being blended with xanthan gum.

Description

technical field [0001] The invention relates to acacia extracts, in particular to a saponins polysaccharide gum and applications thereof. Background technique [0002] Due to its unique rheology, galactomannan gum is widely used as a thickener, stabilizer, flocculant, dispersant, etc. in petroleum drilling, food and medicine, textile printing and dyeing, mining and mineral processing, military explosives, Daily chemical ceramics, architectural coatings, paper and other industries. [0003] Galactomannan gum is divided into leguminous herbaceous plant gum and leguminous woody plant gum according to resource varieties. The United States began to develop and utilize woody carob gum in the early 20th century, and it has been used in many fields by the 1940s. field. During World War II, carob resources were greatly reduced. The United States searched for and developed herbal guar beans to replace carob beans. Guar beans are native to India and Pakistan, and the United States ha...
