Abstract
The invention discloses a novel process for improving crystalline maltose yield. The process is characterized in that: maltose mother liquor after crystallization separation is injected into a saccharifying tank independently, or the maltose mother liquor, together with liquefied starch milk, is injected into the saccharifying tank for saccharification to convert trisaccharides, tetrasaccharides and polysaccharides in the maltose mother liquor into maltose; and the saccharification process has the following technical parameters: the saccharification time is 40 to 60 h, the pH value is 5.0 to 5.5, the temperature is between 60 and 62 DEG C, the dosages of pullulanase, beta-amylase and maltotriose enzyme which are added for synergistic hydrolysis are 0.5 to 2.5 L/TDS, 0.8 to 3 L/TDS and 0.5 to 2 L/TDS respectively. In the process, the mother liquor in the production process of crystalline maltose is sacchrified again to further convert the trisaccharides, the tetrasaccharides and the polysaccharides in the mother liquor into the maltose, so the yield of maltose dry basis can be improved by 15 to 20 percent; therefore, the utilization rate of the maltose mother liquor is improved, the cost is reduced, and the economic benefit and the added value of the product are improved.
Description
Technical field
The invention belongs to technical field of functional sugar production, relate to a kind of novel method that improves crystalline maltose yield.
Background technology
Maltose is the disaccharide that a kind of 1-4 key links, it is one of low sugariness carbohydrate of low heat value, sugariness is equivalent to 30～40% of sucrose, calorific value only is 5% of a sucrose, be additive, preservation agent, the wetting Agent for Printing Inks of using always, have good fermentable, do not play Maillard reaction basically, the every field that is used for food service industry is as solid food, liquid foodstuff, frozen product, colloid food etc.It also has a purposes widely industrial.
Have a large amount of maltose mother liquor in the crystalline-maltose production process and produce, the mother liquor dry matter content is about 50%, and wherein maltose purity is about 80%, and trisaccharide maltose, maltotetrose and purity of polysaccharide are about 18%, monose purity about 2%.Therefore, except the maltose that contains more amount, also contain a large amount of oligose components in the mother liquor.
At present, the maltose mother liquor is mainly sold with the form of waste material or high maltose syrup, makes maltose can better effectively not utilize, and has caused maltose yield and economic benefit on the low side.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned traditional treatment method exists, a kind of novel process that improves crystalline maltose yield is provided, mainly sell to solve prior art maltose mother liquor with the form of waste material or high maltose syrup, maltose fails effectively to utilize, and causes problems such as maltose yield and economic benefit be on the low side.
The technical solution adopted for the present invention to solve the technical problems is: the maltose mother liquor that Crystallization Separation is come out is squeezed into saccharifying tank separately, or the maltose mother liquor squeezed into starch milk liquefaction liquid carry out saccharification in the saccharifying tank, add Pullulanase, beta-amylase and trisaccharide maltose enzyme synergetic hydrolysis, make in the maltose mother liquor trisaccharide maltose, maltotetrose and polysaccharide once more saccharification be converted into maltose.Use this technology, maltose butt yield can improve 15-20%.
Processing parameter in its saccharifying is: saccharification time 40～60h, pH value 5.0～5.5, temperature 60-62 ℃, add Pullulanase, beta-amylase and trisaccharide maltose enzyme synergetic hydrolysis, enzyme dosage is respectively 0.5-2.5L/TDS, 0.8-3L/TDS, 0.5-2L/TDS.
Enzyme concentration is used as standard with contained butt amount in the mother liquor, so enzyme concentration of the present invention is the required saccharifying enzyme quantity of mother liquor that whenever contains 1 ton of butt.
Adopting positively effect of the present invention is mother liquor saccharification once more with the maltose production process, improved the utilization ratio of maltose mother liquor, make wherein trisaccharide, tetrose and polysaccharide further be converted into maltose, thereby improved the yield of maltose, reduce cost, improved economic benefit and value-added content of product.The maltose mother liquor is after above-mentioned saccharification, and maltose purity can reach 88～92%.Maltose mother liquor and starch milk liquefaction liquid mix carry out above-mentioned saccharification after, maltose purity can reach 89～94%, effect is better than separately mother liquor being carried out saccharification result, transformation efficiency is higher.
Specific implementation method:
Example 1
The maltose mother liquor is squeezed into saccharifying tank, saccharification time 45 hours, and pH5.4,60 ℃ of temperature add Pullulanase, beta-amylase and trisaccharide maltose enzyme, and enzyme dosage is respectively 1.2L/TDS, 1.5L/TDS, 1.0L/TDS.Obtain maltose purity after the saccharification and be 91% solution.
Example 2
Maltose mother liquor and starch milk liquefaction liquid are squeezed into saccharifying tank by 5: 5 mixed, saccharification time 48 hours, and pH5.3,61 ℃ of temperature add Pullulanase, beta-amylase and trisaccharide maltose enzyme, and enzyme dosage is respectively 1.2L/TDS, 1.5L/TDS, 1.0L/TDS.Obtain maltose purity after the saccharification and be 93% solution.
Claims (2)
1. novel process that improves crystalline maltose yield, it is characterized in that the maltose mother liquor after the Crystallization Separation is squeezed into saccharifying tank separately, or the maltose mother liquor after the Crystallization Separation squeezed into starch milk liquefaction liquid carries out saccharification in the saccharifying tank, make in the maltose mother liquor trisaccharide, tetrose and polysaccharide once more saccharification be converted into maltose; Processing parameter in its saccharifying is: saccharification time 40～60h, pH value 5.0～5.5, temperature 60-62 ℃, add Pullulanase, beta-amylase and trisaccharide maltose enzyme synergetic hydrolysis, enzyme dosage is respectively 0.5-2.5L/TDS, 0.8-3L/TDS, 0.5-2L/TDS.
2. according to the described a kind of novel process that improves crystalline maltose yield of claim 1, it is characterized in that enzyme concentration is the required saccharifying enzyme quantity of mother liquor that whenever contains 1 ton of butt.
