Description
Technical field
The present invention relates to cane molasses manufacture field, more particularly to a kind of cane molasses decoloration process.
Background technology
Cane molasses are a kind of accessory substances of cane sugar manufacture industry, are a kind of dark-brown, thick and semifluid liquid.
Molasses are cheap and easy to get and the technique of the utilization of resources 11 is simple, so, have in chemical industry, light industry, food, medicine and building material industry higher
Value, how simply, efficient, low and coloring matter leverages application of the molasses in industry-by-industry in molasses,
Cost, which removes coloring matter in molasses, turns into first of threshold of molasses application.
Coloring matter mainly includes aldehydes matter and high molecular polymer in cane molasses, in cane milling and clarifying process
The dark matter that aldehydes matter is decomposed in middle sugarcane and the effect of polycondensation forms HMW again, in addition, in production process
Reduced sugar and amino acid reaction（Maillard reaction Maillard reaction）The brown of the high relative molecular mass generated is gathered
Compound.The pigment formed through caramelization and Maillard reaction, it is final all to accumulate in molasses.
Existing molasses discoloration method mainly has two kinds, and one kind is in acid hydrolysis molasses after colloid, utilizes charcoal absorption
Pigment, second is to utilize membrane filtration after molasses dilution is handled, the pigment in the part molasses that dam.Both approaches exist bright
Aobvious shortcoming, first, be required to be diluted with water, cause very big environmental pollution, second, production cost it is high, it is difficult to promote, the 3rd,
It is not notable that pigment departs from effect.
The content of the invention
Based on this, it is necessary to provide a kind of cane molasses decoloration process.
A kind of cane molasses decoloration process, comprises the following steps：
After first cane molasses are mixed with composite assistant, wherein, the purity of first cane molasses（Total sugar/folding
Penetrate brix）Between 60.0% and 70.0%, the composite assistant is the mixture containing 1 part of lactic acid and 12 parts of glycerine, obtains
Two cane molasses；
Air is filtered, becomes pure air, and compresses and preheats, obtains handling air；
Second cane molasses and processing air are ejected into immobilised enzymes column by injection apparatus（Enzyme plate）On, carry out enzyme
Processing, wherein, the immobilised enzymes column is Laccase Immobilization column, and it is 55u/cm that the ratio of immobilised enzymes, which is lived,2；
By the 3rd cane molasses of immobilised enzymes ferment treatment, as decolourize molasses.
