preparation example Construction

[0022] In order to solve the problems of low conversion rate, complex process and high production cost in the previous preparation methods of fructo-oligosaccharides, the invention provides a non-synthetic preparation method of fructo-oligosaccharides, which is specifically prepared by the following steps:

[0023] 1) The inulin solution is hydrolyzed by endo-inulinase, and the enzymatic hydrolysis product is filtered to obtain a filtrate;

[0024] 2) Decolorize the filtrate with activated carbon;

[0025] 3) After decolorization, use PAM flocculant for flocculation treatment;

[0026] 4) Desalination by ion exchange resin, further impurity removal, deodorization, and purification of fructooligosaccharides;

[0027] 5) Evaporate, concentrate and spray dry the above product to obtain fructooligosaccharides.

[0028] The method for preparing non-synthetic fructo-oligosaccharides in the present invention uses inulin as a raw material and uses an endo-inulinase method to produce...

[0037] project index character White or light yellow amorphous powder odor fructooligosaccharide fragrance taste Sweet and refreshing

[0038] The physical and chemical indicators of the non-synthetic fructooligosaccharides are shown in Table 2.

[0040] project index Total content of fructo-oligosaccharides (mass fraction) / % ≥ 95.0 Moisture (mass fraction) / % ≤ 5.0 PH value 4.5~7.0 Conductivity ash / % ≤ 0.4

[0041] Compared with the production of fructo-oligosaccharides from sucrose, this method has obvious advantages in the total content of fructo-oligosaccharides in the final product.

[0042] The final product of the sucrose method has a high content of glu...

Abstract

The invention discloses a preparation method of non-synthesized fructooligosaccharide. The preparation method comprises the following steps of (1) carrying out enzymolysis on an inulin solution, and filtering an enzymolysis product to obtain a filtrate; (2) decolorizing the filtrate; (3) flocculating the decolorized filtrate; (4) after flocculating and filtering, desalting by using ion exchange resin, removing impurities, eliminating odor and purifying; (5) evaporating, concentrating and spray-drying the product to obtain fructooligosaccharide. The preparation method of the non-synthesized fructooligosaccharide is used for preparing 95-97% of fructooligosaccharide with the fructose polymerization degree of 2-9 by utilizing the partial hydrolysis action of an incision enzyme of inulin; in addition, compared with a sucrose conversion method, the preparation method has the advantages of simple process, few byproducts, high conversion rate and the like.

Description

technical field [0001] The invention relates to a preparation method of fructo-oligosaccharide, which belongs to the field of food processing, in particular to a preparation method of non-synthetic fructo-oligosaccharide. Background technique [0002] Fructo-oligosaccharide is a functional oligosaccharide, its sweetness can reach 0.6 times that of sucrose. It not only maintains the pure sweet taste of sucrose, but also is refreshing than sucrose, and has a fat-like fragrance and refreshing creamy feeling. Fructose-oligosaccharide is a kind of water-soluble dietary fiber, which is fermented by bacteria in the large intestine to produce L-lactic acid, which can dissolve calcium, iron, zinc and other minerals, and promote the absorption of minerals by the human body; it has the functions of regulating intestinal flora, proliferating Bifidobacterium, a new type of sweetener with health functions such as regulating blood lipids, improving immunity, and anti-caries, has been used ...
