Embodiment 1

[0049] The preparation method of xenograft syrup comprises acid hydrolysis, calcium carbonate neutralization, yeast culture, ion exchange, and vacuum concentration, and the steps are as follows:

[0050] (1) Mix corn husks (dry basis) with sulfuric acid solution at a weight ratio of 1kg: 8kg, the concentration of the acid solution is 2.0wt%, hydrolyze at 115° C. for 3 hours, filter the corn husk residue, and obtain the corn husk hydrolyzate;

[0051] (2) Add light calcium carbonate to the corn bran hydrolyzate prepared in step (1) to adjust the pH to 4.0, let it stand at 75°C for 1 hour, filter out the precipitate, and obtain a neutralized hydrolyzate; add 0.5wt% activated carbon, at 80°C, decolorize for 30min;

[0052] (3) Cool the neutralized hydrolyzate after the decolorization treatment in step (2) to 30°C, inoculate yeast, the inoculum amount of yeast is 0.2wt% (dry basis), ventilate, maintain dissolved oxygen at 10-15%, and cultivate 12h, use the microfiltration membran...

Embodiment 2

[0059] The preparation method of xenograft syrup comprises acid hydrolysis, calcium carbonate neutralization, yeast culture, ion exchange, and vacuum concentration, and the steps are as follows:

[0060] (1) Mix corn bran (dry basis) with sulfuric acid solution in a weight ratio of 1kg: 10kg, the concentration of the acid solution is 1.0wt%, hydrolyze at 125°C for 3.5h, filter the corn bran residue, and obtain the corn bran hydrolyzate;

[0061] (2) Add light calcium carbonate to the corn bran hydrolyzate prepared in step (1) to adjust the pH to 5.0, let it stand at 80°C for 1 hour, filter out the precipitate, and obtain a neutralized hydrolyzate; add 1.5wt% activated carbon, at 75°C, decolorize for 30min;

[0062] (3) Cool the neutralized hydrolyzate after the decolorization treatment in step (2) to 26°C, inoculate yeast, the inoculum amount of yeast is 1.5wt% (dry basis), ventilate, maintain dissolved oxygen at 15-20%, and cultivate 16h, use the microfiltration membrane to ...

Embodiment 3

[0069] The preparation method of xenograft syrup comprises acid hydrolysis, calcium carbonate neutralization, yeast culture, ion exchange, and vacuum concentration, and the steps are as follows:

[0070] (1) Mix corn husks (dry basis) with sulfuric acid solution at a weight-to-volume ratio of 1kg: 9kg, the concentration of the acid solution is 2.0wt%, hydrolyze at 120°C for 2.5h, filter the corn husk residue, and obtain the corn husk hydrolyzate;

[0071] (2) Add light calcium carbonate to the corn bran hydrolyzate prepared in step (1) to adjust the pH to 4.5, let stand at 75°C for 1 hour, filter out the precipitate, and obtain a neutralized hydrolyzate; add 1.0wt% activated carbon, at 78°C, decolorize for 30min;

[0072] (3) Cool the neutralized hydrolyzate after the decolorization treatment in step (2) to 28°C, inoculate yeast, the inoculum amount of yeast is 1.0wt% (dry basis), ventilate, keep dissolved oxygen at 12-16%, and cultivate 15h, use the microfiltration membrane ...

Abstract

The invention relates to xylose-arabinose syrup and a method for preparing the same, belonging to the technical field of the food additive. The xylose-arabinose syrup comprises 60-80 percent by weight of dry matters and 20-40 percent by weight of water. The dry matters comprise the following components by weigh percent by taking the weigh of the dry matters as the radix: 56-58 percent of xylose, 34-36 percent of arabinose, 0.5-4.0 percent of glucose and the balance of impurities. The xylose-arabinose syrup integrates the advantages of both the xylose and the arabinose and has the multiple efficacy of reducing the blood sugar, preventing the obesity, improving the diabetes symptoms after being added to food. The xylose-arabinose syrup can be widely used and can be hydrogenated to further produce the complex sugar alcohol. The source of corn husk which is used as the raw material of the xylose-arabinose syrup is extensive, thus the xylose-arabinose syrup is less affected by the seasonable factor. The xylose-arabinose syrup has better development prospect and market prospect.

Description

technical field [0001] The invention relates to xyloara syrup with xylose and arabinose as main components and a preparation method thereof, belonging to the technical field of food additives. Background technique [0002] Both xylose and arabinose are five-carbon sugars with good health functions. Xylose and arabinose are functional syrups with xylose and arabinose as the main components. At present, there is no research and production of this product at home and abroad. Xylose production It is produced from corncobs, and there is no industrialized manufacturer of arabinose in China. [0003] Corn bran is a by-product of corn starch production, and its output generally reaches 12.5% ​​of the total corn. The value of the product is low, and it is mainly sold as feed raw materials. Corn bran is rich in cellulose and hemicellulose, and various sugars can be obtained by acid hydrolysis, including six-carbon sugar and five-carbon sugar, of which xylose is 30-35%, arabinose is a...
