Embodiment 1

[0049] The preparation method of mu arabic syrup includes acid hydrolysis, calcium carbonate neutralization, yeast culture, ion exchange, and vacuum concentration. The steps are as follows:

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

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

[0052] (3) Cool the neutralized hydrolysate after decolorization in step (2) to 30℃, inoculate yeast, the yeast inoculation amount is 0.2wt% (dry basis), ventilate to maintain dissolved oxygen at 10-15%, and cultivate 12h, use a microfiltration membrane to filter out the yeast to obtain the f...

Embodiment 2

[0059] The preparation method of mu arabic syrup includes acid hydrolysis, calcium carbonate neutralization, yeast culture, ion exchange, and vacuum concentration. The steps are as follows:

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

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

[0062] (3) Cool the neutralized hydrolysate after decolorization in step (2) to 26℃, inoculate yeast, the yeast inoculation amount is 1.5wt% (dry basis), ventilate to maintain dissolved oxygen at 15-20%, and cultivate 16h, use a microfiltration membrane to filter out the yeast to obtain th...

Embodiment 3

[0069] The preparation method of mu arabic syrup includes acid hydrolysis, calcium carbonate neutralization, yeast culture, ion exchange, and vacuum concentration. The steps are as follows:

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

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

[0072] (3) Cool the neutralized hydrolysate after decolorization in step (2) to 28°C, inoculate yeast, the yeast inoculation amount is 1.0wt% (dry basis), ventilate to maintain dissolved oxygen at 12-16%, and cultivate 15h, use a microfiltration membrane to filter out the yeast t...

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 a xylose syrup with xylose and arabinose as main components and a preparation method thereof, and belongs to the technical field of food additives. Background technique [0002] Xylose and arabinose are both five-carbon sugars and have good health care functions. Xylose syrup is a functional syrup with xylose and arabinose as the main components. Currently, there is no research and production of this product at home and abroad. Xylose production It is produced using corn cob as raw material, and there is no industrialized manufacturer of arabinose in China. [0003] Corn husk 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 a feed material. Corn husk is rich in cellulose and hemicellulose. Acid hydrolysis can produce various sugars, including six-carbon sugars and five-carbon sugars. Among them, xylose is 30 to 35%, arabino...
