Embodiment 1

[0029] 10kg of wild honey locust gum powder is added to stirring device, add 0.75kg sodium hydroxide, 1.5kg95% ethanol, 0.75kg water, stir for 45 minutes, semi-wet wild honey locust gum powder is placed in microwave drying equipment, adjust microwave power 750 watts, Treat for 25 minutes, dissolve the treated rubber powder in water to form a solution with a concentration of 15%, adjust the pH to 7.0 with citric acid, pass the solution through a hollow fiber membrane with a molecular weight cut-off of 2000 Daltons at room temperature, and work at a pressure of 0.12Mpa. The Acacia oligosaccharide solution passing through the membrane was spray-dried, and the spray drying outlet temperature was controlled at 85° C. to obtain 7.3 kg of white Acacia oligosaccharide powder.

Embodiment 2

[0031] Put 10kg of fenugreek powder into the stirring device, add 0.6kg of sodium hydroxide, 1.3kg of isopropanol, 0.7kg of water, stir for 35 minutes, put the semi-wet powder of fenugreek in the microwave drying equipment, adjust the microwave power 500 watts, treat for 15 minutes, dissolve the processed rubber powder in water to make a solution with a concentration of 12%, adjust the pH to 7.0 with hydrochloric acid, pass the solution through a hollow fiber membrane with a molecular weight cut-off of 2000 Daltons at room temperature, and work at a pressure of 0.14Mpa , and spray-dry the Acacia oligosaccharide solution passing through the membrane, and the temperature of the spray-drying air outlet is controlled at 75° C. to obtain 8.6 kg of white oligosaccharide powder.

Embodiment 3

[0033] Add 10kg of guar gum powder into the stirring device, add 0.8kg of potassium hydroxide, 1.5kg of methanol, 0.8kg of water, stir for 25 minutes, place the semi-wet wild honey locust gum powder in the microwave drying equipment, adjust the microwave power to 1200 watts, and process After 10 minutes, dissolve the treated rubber powder in water to make a 10% solution, adjust the pH to 7.0 with citric acid, pass the solution through a hollow fiber membrane with a molecular weight cut-off of 2000 Daltons at room temperature, and pass the membrane at a working pressure of 0.15Mpa. Acacia oligosaccharide solution was spray-dried, and the spray drying outlet temperature was controlled at 85° C. to obtain 6.8 kg of white oligosaccharide powder.

Abstract

The present invention discloses semi-dry microwave treating process of preparing galactomanoligose. Galactomanoligose is prepared with galactomannan powder as material and through the steps of hydration, microwave treatment, water dissolving and neutralizing, membrane separating and drying. The process has short production period, high production efficiency, less pollution and low power consumption.

Description

technical field [0001] The invention relates to a method for preparing galactomannan oligosaccharides by semi-dry microwave treatment. Background technique [0002] Oligosaccharides, also known as oligosaccharides, refer to straight-chain or branched-chain sugars formed by connecting 2 to 10 monosaccharides through non-α-1,4-glycosidic bonds. It has good physical and chemical properties such as low heat, stability, safety, non-toxicity, and no residue. It is a recognized functional factor of health food, which can significantly proliferate beneficial bacteria such as bifidobacteria, regulate the balance of intestinal flora; effectively inhibit harmful bacteria and reduce toxin production; enhance immunity, inhibit and prevent tumors; promote digestion and absorption; moisturize Laxative, prevent constipation; promote the absorption of minerals such as calcium, magnesium, iron, zinc, etc. Widely used in dairy products, baby food, health products, medicines, etc. [0003] Si...
