Method of decolouring glucose saccharifying liquid by ion exchange resin

Abstract

The invention discloses the method for decolouring dextroglucose liquid with ion exchange resin. The method comprises the following steps: confirming the temperature, concentration and flow velocity, putting the 35-45% liquid glucose into ion-exchange device at 40-50Deg.C and 2.5-4.0BV / h; or using activated charcoal to decolour liquid glucose, and then putting it into ion-exchange device. The light transmittance ratio of the decolour liquid is up to 100%, and the conductance is reduced to below 10 mus / cm.

Description

technical field

[0001] The invention relates to a production method of crystalline glucose, in particular to a method for decolorizing glucose saccharification liquid by using ion exchange resin. Background technique

[0002] Glucose is a kind of monosaccharide, which is an important source of energy for humans and animals, and has a wide range of uses in the food industry and pharmaceutical industry. The color of glucose is a very important sensory index of glucose products. Choosing an economical and very effective decolorization method has always been a concern of many manufacturers. Glucose is produced through jet liquefaction at high temperatures, during which some pigments are produced. Its pigment is the product of the reaction of sugar and colored substance precursors. For example, melanoids are produced by the interaction of sugar and amino acids (Maillard reaction), and another type of pigment is produced by the thermal degradation of sugar (such as caramel).
