Embodiment 1

[0020] 1.1, Milling

[0021] After the corn kernels are cleaned of impurities and stones, they are prepared with water to make the total moisture of the corn kernels reach 16%, the water temperature is 40°C, and the time is 5 minutes, and then transported to the peeling equipment for the separation of the cortex, using "gradual pressure and rotary peeling" , so that the corn cortex is completely separated from the kernel and quickly sucked out of the peeling room, and the unpeeled corn continues to be peeled repeatedly. The sifted skin is powdered, and the powder from the belt is recovered.

[0022] The peeled corn is watered again to make the total moisture of the corn reach 19%, and the time is 1.5h, and then the embryo is broken. After the embryo is sieved, the separated germ is powdered, and the powder brought out by the germ is recovered. , after breaking the embryo, the crushed corn is screened and entered into the mill to be crushed into 80-100 mesh corn flour, the cor...

[0028] 2.1, Milling

[0029] After the corn kernels are cleaned of impurities and stones, they are prepared with water to make the total moisture of the corn kernels reach 18%, the water temperature is 30°C, and the time is 10 minutes, and then transported to the peeling equipment for the separation of the cortex, using "gradual pressure and rotary peeling" , so that the corn cortex is completely separated from the kernel and quickly sucked out of the peeling room, and the unpeeled corn continues to be peeled repeatedly. The sifted skin is powdered, and the powder from the belt is recovered.

[0030] The peeled corn is watered again to make the total moisture of the corn reach 20% for 1 hour, and then the embryo is broken. After the embryo is sieved, the separated germ is powdered and the powder brought out by the germ is recovered. After breaking the embryo, the groat corn is screened and entered into a mill to be crushed into 80-100 mesh corn flour with a fat content of 0.1...

Abstract

The invention provides preparation method for high-purity isomaltose hypgather, which takes corn starch as a raw material and adopts simulated moving bed chromatography separation technology, also comprises a preparation method of the corn starch. The specific method comprises the steps of 1. preparing the corn starch by adopting a dry method; 2. directly preparing the isomaltose hypgather by adopting the corn starch to obtain 50 type isomaltose hypgather; and 3. separating glucose by adopting a simulated moving bed chromatography separation system and taking water as an eluent under the operation temperature being 60-70 DEG C to obtain the high-purity isomaltose hypgather and glucose syrup. Due to the adoption of the method provided by the invention, the production links from the corn kernels to the isomaltose hypgather can be reduced, the production cost and the environment burden can be lowered, meanwhile, the fermented flavor in a finished product can be reduced, and the final product quality is improved. IMO in the isomaltose hypgather prepared by the invention can be more than 92%, and the content of soluble protein can be more than 0.85%.

Description

technical field [0001] The present invention relates to a kind of preparation method of high-purity isomalto-oligosaccharide, more specifically relate to the preparation method of the corn flour of producing isomalto-oligosaccharide and the method for directly producing high-purity isomalto-oligosaccharide with corn flour as raw material. Background technique [0002] With the improvement of people's living standards and their concern for their own health, the market of Yikang food and health food has broad prospects for development. Isomaltooligosaccharide is called a prebiotic, because it has the function of proliferating beneficial bacteria in the intestine and improving the digestive system of the human body. It has been widely added to food and health products, and the market demand is huge. [0003] At present, the main raw material for the production of isomaltooligosaccharide is corn starch or corn steep liquor. The traditional wet corn starch processing technology h...
