Refining technique method in malt amylin production process

Abstract

The invention discloses a refining process method for the productionof maltodextrin. The technical proposal of the method is as follows: the prior ion exchange refining system is adjusted, and a macroporous nonpolar adsorption resin column is added behind an adjustment column to form an ion exchange and adsorption resin refining system; a decolorized sugar solution directly enters the adsorption resin column through an ion exchange column for further removal of impurities and peculiar smell, and then is sent to a concentration and drying system to be processed into a dextrine product. The light transmittance of the sugar solution treated by adopting the technical proposal is improved to 96.2 percent from the prior 92.2 percent, and is improved by 3. 28 percent; the chroma is improved to a value less than 15Hz from a value which is averagely less than 40Hz; the white content is improved to 92.5 percent from average 89 percent; and particularly the odor of the product is apparently improved, is reduced to a light odor or no odor from the prior strong acid and base odor and burned odor, and achieves the requirement of customers.

Description

Technical field: [0001] The invention belongs to the field of maltodextrin production and relates to a refining process of maltodextrin. Background technique: [0002] Maltodextrin is one of the deep-processing products of starch. It is a product between starch and starch sugar obtained by controlled low-level enzymatic hydrolysis from starch slurry. Maltodextrin is widely used in candies, beverages, In food, medicine, cosmetics and other industries, it can also be used as a dispersant and stabilizer in other industrial production processes. [0003] The existing dextrin products are mainly produced according to the national standard product standards, and the production process is also controlled to meet the national standard requirements. However, with the improvement of quality requirements of food and beverage users, the whiteness of the original product standards , odor, ash and other indicators can not meet the requirements of users, the need to further improve the qu...
