Problems solved by technology

[0004] At present, the raw material for the production of isomaltooligosaccharide is mainly corn starch or corn steep liquor. The traditional wet corn starch processing technology has disadvantages such as high energy consumption and serious pollution, and the comprehensive utilization rate of corn is not high.

Embodiment

[0020] Taking corn flour made by peeling and degerming as raw material, it includes the following steps:

[0021] (1) Dissolve the corn flour in water, add 0.06-0.1% of the weight of the corn flour to the dissolving solution, adjust the pH to 5.5-6.0, and keep it at 87-92°C for 15-25 minutes;

[0022] (2) Cool the dissolving solution to 40-50℃, add 0.1-0.2% of the weight of corn flour fungal enzyme, keep it for 15-20h, then add 0.6-1% of the weight of corn flour α-glucosidase, 40 Incubate at -50°C for 10-15 hours, adjust the pH to neutral, add 1-2% of the weight of the corn flour with neutral protease, enzymatically hydrolyze at 35-40°C for 2-4 hours to obtain an enzymatic hydrolysis solution;

[0023] (3) Filter the enzymatic hydrolysate, decolorize it, refine it through a continuous particle exchange system, and finally concentrate to obtain a concentrated solution; adjust the pH of the enzymatic hydrolysate to 4-5, add flocculants, and stand at 70-80°C for 40°C -50min, then add a...

Abstract

The invention belongs to the technical field of starch sugar and especially relates to an isomaltose hypgather cleaning and production method. The isomaltose hypgather cleaning and production method comprises the following steps: using peeled and degermed corn flour as a raw material, dissolving the corn flour by adding water, adding alpha-amylase in the dissolved solution, and adjusting pH value and keeping warm; cooling the dissolved solution and adding fungal enzyme for thermal insulation, adding alpha-transglucosidase and keeping warm, adjusting pH to neutral, and adding neutral protease to carry out enzymolysis so as to obtain an enzymatic hydrolysate; filtering, decolouring and refining the enzymatic hydrolysate and finally concentrating to obtain a concentrate; separating the concentrate by a sequential simulated moving bed, respectively collecting effluents of isomaltose hypgather, glucose and polysaccharide, concentrating the isomaltose hypgather eluant, and drying to obtain the product. The method provided by the invention has advantages of simple step and stable reaction, is easy to carry out, is adopted to effectively raise production efficiency and utilization rate of raw materials, reduce energy consumption and production cost and mitigate environmental burden, and is beneficial to industrial production.

Description

(1) Technical field [0001] The invention belongs to the technical field of starch sugars, and particularly relates to a clean production method of isomalt oligosaccharides. (2) Background technology [0002] Isomaltooligosaccharides are oligosaccharides in which 2-8 glucose molecules are connected by α-1,6 glycosidic bonds; usually, isomalt oligosaccharides are not fermented by yeast and are non-fermentable oligosaccharides. Isomalt-oligosaccharides can effectively promote the growth and reproduction of beneficial bacteria-Bifidobacterium in the human body, so it is also called "Bifidobacterium growth promoting factor", or "Bifido factor" for short. After years of clinical and practical applications, it has been shown that bifidobacteria have many health-care functions, and isomaltose-oligosaccharides, as a promoting factor for bifidobacteria, have naturally attracted attention. [0003] Because of its excellent processing characteristics, isomalt oligosaccharides have no spec...
