Embodiment 1

[0034] (1) After pretreatment, saccharification, plate and frame filtration, sterilization, decolorization, ion exchange, purification and concentration of xylo-oligosaccharide production raw materials, the content of 80 wt. % (80wt% in dry matter total sugar is xylooligosaccharide) xylooligosaccharide concentrate, specifically as follows:

[0035] a. Mix deionized water, xylooligosaccharide production raw materials and MgO at a weight ratio of 5:1:0.15, and cook at 165° C. for 3 hours. Squeeze out the yellow liquid in the cooked pulp and wash it 6 times with deionized water, then extract it with 10wt% KOH aqueous solution for 6h, filter and remove the cellulose to obtain the filtrate, then precipitate the filtrate with 4 times the volume of absolute ethanol to obtain the rich Xylan-containing hemicellulose;

[0036] b. Saccharification: mix deionized water, the above-mentioned xylan-rich hemicellulose and xylanase in a weight ratio of 9:1:0.05, and then saccharify in a solut...

Embodiment 2

[0044] (1) After pretreatment, saccharification, plate and frame filtration, sterilization, decolorization, ion exchange, purification and concentration of xylo-oligosaccharide production raw materials, the content obtained with a refractive index of 70% (equal to total sugar in dry matter) is 60wt % (60wt% in the total sugar of dry matter is xylooligosaccharide) concentrated solution of xylooligosaccharides, specifically with embodiment 1;

[0045] (2) Dihydrate crystalline trehalose, mannitol and gum arabic were heated and dissolved in deionized water at 70°C to obtain dihydrate crystalline trehalose solution, mannitol solution and gum arabic solution respectively. Xylan concentrated solution, dihydrate crystalline trehalose solution and mannitol solution are added to the gum arabic solution, and fully mixed; the mass ratio of the dihydrate crystalline trehalose, mannitol and acacia gum is 12:18:20, and the above The weight ratio of the dry matter total sugar in the xylo-oli...

Embodiment 3

[0049] (1) After pretreatment, saccharification, plate and frame filtration, sterilization, decolorization, ion exchange, purification and concentration of xylo-oligosaccharide production raw materials, the content of 40wt obtained with a refractive index of 60% (equal to total sugar in dry matter) % (40wt% in the total sugar of dry matter is xylo-oligosaccharides) concentrated solution of xylo-oligosaccharides, specifically with embodiment 1;

[0050] (2) Dihydrate crystalline trehalose, mannitol and gum arabic were heated and dissolved in deionized water at 70°C to obtain dihydrate crystalline trehalose solution, mannitol solution and gum arabic solution respectively. Xylan concentrated solution, dihydrate crystalline trehalose solution and mannitol solution are added to the gum arabic solution, and fully mixed; the mass ratio of the dihydrate crystalline trehalose, mannitol and arabic gum is 7:12:14.3, and the above The weight ratio of the dry matter total sugar in the xylo...

Abstract

The invention discloses a preparation method of a composite functional xylooligosaccharide composition for facilitating drying and resisting moisture absorption. The composite functional xylooligosaccharide composition comprises the following raw materials: an xylooligosaccharide concentrated solution with total sugar of dry matter being 30-70wt%, crystallized trehalose dehydrate, mannite and Arabic gum, wherein in the total sugar of dry matter, xylooligosaccharide accounts for 25-95wt%, the mass ratio of the crystallized trehalose dehydrate, the mannite and the Arabic gum is 5-15:5-20:10-20,and the weight ratio of the total sugar of dry matter in xylooligosaccharide concentrated liquor to the sum of the crystallized trehalose dehydrate, the mannite and Arabic gum is 1-3: 1. The formula is scientific and reasonable, the obtained product tastes delicious, a glass transition temperature is high, the product cannot adhere to a wall in a dyring process, the mobility and stability of the product are good, moisture absorption resistance is high, caking and liquefying can be prevented effectively, and follow-up processing, storage, conveying, selling and utilization can be prevented effectively.

Description

technical field [0001] The invention belongs to the field of food science and technology, and in particular relates to a preparation method of a composite functional xylo-oligosaccharide composition that promotes drying and resists moisture absorption. Background technique [0002] Xylooligosaccharides, also known as xylooligosaccharides, refer to functional polymeric sugars composed of 2 to 7 xylose molecules linked by β-1,4 glycosidic bonds. The sweetness of xylo-oligosaccharide is about 40% of that of sucrose, and it has a pure sweetness similar to that of sucrose. It can be used as a functional sweetener and additive; xylo-oligosaccharide is an excellent bifidobacteria proliferation factor that can promote The growth of beneficial bacteria in the intestinal tract can inhibit the reproduction of harmful microorganisms. It has the effects of improving constipation, anti-cancer, lowering cholesterol and enhancing the immune function of the body. It is one of the most promis...
