Embodiment 1

[0050] A kind of production technology of present embodiment prepares solid sorbitol and co-produces fructose syrup, comprises the following steps:

[0051] (1) The starch is prepared into starch milk of 20 degrees Baume (°Be'), and the concentration of Na is 10% by mass percent. 2 CO 3 The solution adjusts the pH value of the starch milk to 5.7-6.0. Calculated based on the dry matter of the starch milk, add 400g / t of high-temperature-resistant a-amylase (Novoxiry high-temperature-resistant a-amylase), and liquefy at 108°C. A liquefied liquid (A) is obtained.

[0052] (2) Use 30% hydrochloric acid to adjust the pH value of the liquefaction solution to 4.0-4.4, then add 450g / t compound enzyme preparation (purchased from Novozymes, trade name: Dextrozyme DX), and saccharify at 60°C for 48h to obtain A saccharified liquid (B) with a glucose content of 95.5%.

[0053] (3) First use a vacuum drum filter to filter the saccharification solution to remove protein, then add 0.2% act...

Embodiment 2

[0070] A kind of production technology of present embodiment prepares solid sorbitol and co-produces fructose syrup, comprises the following steps:

[0071] (1) The starch is prepared into starch milk of 18 degrees Baume (°Be'), and the concentration of 10% Na with a mass percent concentration 2 CO 3 The solution adjusts the pH value of the starch milk to 5.7-6.0. Calculated based on the dry matter of the starch milk, add 400g / t of high-temperature-resistant a-amylase (Novoxiry high-temperature-resistant a-amylase), and liquefy at 108°C. A liquefied liquid (A) is obtained.

[0072] (2) Use 30% hydrochloric acid to adjust the pH value of the liquefaction solution to 4.0-4.4, then add 450g / t compound enzyme preparation (purchased from Novozymes, trade name: Dextrozyme DX), and saccharify at 60°C for 48h to obtain A saccharified liquid (B) with a glucose content of 95.5%.

[0073] (3) First filter the saccharification solution with a nanofiltration membrane to remove protein, ...

Abstract

The invention discloses a process for preparing neosorb and coproducing fructose-glucose syrup. The process comprises the steps of (1) preparing a saccharified liquid from starch, and removing impurities to obtain a refined saccharified liquid; (2) carrying out nanofiltration treatment on the refined saccharified liquid to respectively obtain glucose filtrate and a disaccharide-concentrated liquid; (3) preparing neosorb from glucose filtrate; (4) carrying out nanofiltration treatment on the disaccharide-concentrated liquid to respectively obtain a glucose washing and filtering liquid and a washed and filtered concentrated liquid; and (5) preparing the fructose-glucose syrup from the glucose washing and filtering liquid, and mixing the washed and filtered concentrated liquid and the starch in the step (1) to prepare the saccharified liquid. According to the process, a continuous nanofiltration separation technology is adopted, the refined saccharified liquid is separated into several components with different glucose contents, then, products such as neosorb and the fructose-glucose syrup are respectively prepared according to different contents of all the components, and a low-content glucose solution is recycled, so that the whole process has the advantages that the saccharified liquid is efficiently utilized, and no resources are wasted.

Description

technical field [0001] The invention belongs to the technical field of starch deep processing, and in particular relates to a production process for preparing solid sorbitol and co-producing fructose syrup. Background technique [0002] The full name of sorbitol is sorbitol, and its molecular formula is C 6 h 14 o 6 , with a molecular weight of 182.17; white hygroscopic powder or crystalline powder, flakes or granules, odorless; depending on crystallization conditions, its melting point varies within the range of 88-102°C, and its relative density is about 1.49; easily soluble in water (1g Soluble in about 0.45mL water), slightly soluble in ethanol and acetic acid; it has a cool sweet taste, the sweetness is about half of that of sucrose, and its calorific value is similar to that of sucrose. [0003] Sorbitol is a chemical product with a wide range of uses. It is mainly used to synthesize vitamin C and make explosives. It can also be used directly as medicine (such as sy...
