Abstract

The present invention relates to a process for enzymatic hydrolysis of granular starch into a soluble starch hydrolysate at a temperature below the initial gelatinization temperature of said granular starch.

Description

Starch process
The application is a Chinese patent application (denomination of invention: starch process; The applying date: on February 10th, 2003; Application number: the dividing an application of 03803986.9 (international application no: PCT/DK03/00084)).
Invention field
The present invention relates in the single stage method that granular starch hydrolyzing is become the Zulkovsky starch hydrolysate, this method is carried out under the temperature of the initial gelation temperature that is lower than described granular starch.
Background of invention
Described many with starch change into starch hydrolysate, such as maltose, glucose or extraordinary syrupy method, these hydrolysates both can be used as sweetener, also can be as such as other sugared precursor of this class of fructose.Glucose fermentation can also be become alcohol or other tunning.
The high-molecular weight polymer that starch is made up of glucose unit.It is made up of about 80% amylopectin and 20% amylose starch usually.Amylopectin is the side chain polysaccharide, and wherein the straight chain of α-1,4 D-glucosyl residue connects by α-1,6 glycosidic link.
The amylose starch straight-chain polysaccharide that the D-Glucopyranose unit that connects by α-1,4 glycosidic link constitutes of serving as reasons each other.Starch is being changed in the situation of Zulkovsky starch hydrolysate the starch depolymerization.Depolymerization commonly used by gelling step and two successive processing steps, be that liquefaction process and Mashing process are formed.
Granular starch is made up of water-fast microscopic particles at room temperature.When with aqueous starch when heating slurry, particle swelling and finally breaking, thus starch molecule is scattered in the solution.In this " gelling " technological process, viscosity significantly increases.When solids concn is 30-40% in the typical industrial method, must make starch thinning or " liquefaction " so that can operate on it.Mainly viscosity is reduced at present by enzymatic degradation.In the liquefaction step process, α-Dian Fenmei becomes less side chain and straight chain unit's (Star Dri 5) with the long-chain starch degradation.Liquefaction step is generally under about 105-110 ℃ about 5-10 minute, under about 95 ℃ about 1-2 hour subsequently.Make temperature reduce to 60 ℃ then, add glucoamylase or beta-amylase and optional debranching factor, such as isoamylase or Starch debranching enzyme and make the about 24-72 of saccharification step hour.
Obviously can see that from above-mentioned discussion conventional starch conversion method extremely consumes energy because of the demand to temperature in various steps.Whole technology needs thus to select used in the method enzyme so that can be carried out needn't making under the starch agglomerative condition.These class methods are themes of US4591560, US4727026 and US4009074 and EP0171218 patent.

About 200 hours of the dosage work of the glucoamylase of reactor use 100KNU/kgDS CGT-ase T and 300AGU/kg DS.Use the mean holding time in 35-45 hour the reactor, system produces the DP1=93% glucose syrup with the whole time limit of quiet rum, and productive rate is near 100%.
Under agitation load the 60kgCerestar C x PHARM 03406 type W-Gum that is suspended in 58 ℃ of city tap-waters of 140L to reactor tank.Make steam heated cover with temperature regulation to 60 ℃.Use 30%HCl to make pH reduce to 4.5 from 6.1.Check pH (pH=4.5) after 15 minutes once more.In the time of 0 hour, add the preceding sampling immediately of enzyme CGTase T (100KNU/kg starch) and glucoamylase (300AGU/kg starch) and be used for being determined at desk centrifuge with the sludge volume % of 3000rpm after centrifugal 3 minutes.In addition, the use refractometer is measured the BRIX in the supernatant liquor.Regularly measure the BRIX in sludge volume and the supernatant liquor after the reaction process as mentioned above.
Load cold city tap-water of 186L and 80kg Cerestar C x PHARM03406 type W-Gum for the entry mixers jar.Maintenance to the slow stirring of entry mixers and with 30%HCl with pH regulator to 4.5.Use water coolant that temperature is remained on 7-8 ℃ and add enzyme CGTase T (100 KNU/kg starch) and glucoamylase (300AGU/kg starch).Guarantee low temperature so that do not react.
Open continuously suddenly ° Brix-value stabilization behind (upstart) reactor to 30 hour about 27.Use the pressure drop of 0.15Bar then and guarantee that the maximum phegma of this pressure flow to start microfiltration.Make filtrate be recycled to reactor tank first 5.7 hours.After this in separating tank, collect filtrate and be the function of time stereometry.Start the reactor feed pump at this time point place and be adjusted to flow velocity and be equal to flow of filtrate (L/ minute).Make the volume in the reactor tank keep constant by implementing this step.
Make the starch slurry charging continuously, simultaneously sampling as mentioned above.In addition, get filtrate sample.By increasing the decline that the phegma flow compensates any flow of filtrate, the filter cake on the broken thus film.Thereby pressure drop is also increased.Sample is regarded as the function of the time of HPLC and BRIX filtrate and also measured the volume of collecting.Sampling is used to measure total DS, sludge, ° Brix and sugar is formed and carries out HPLC from reactor simultaneously.
This test duration 220 hours.When this time point, pressure drop increases to about 0.4Bar.
The enzyme system of being made up of CGTase and glucoamylase as the flow of filtrate (based on unitary determination) of function mensuration process period and average flow of filtrate value (integration) demonstration is kept separately in process period and is guaranteed regime flow growing.This results highlight the potential industrial advantages of this stable system.
Result and material balance are listed among the table 16-18.

Compare with the batch test of carrying out in the simple jar that stirs, use the set(ting)value of said hydrolyzed granular starch that the reaction times is significantly reduced.If use 30%DS not run into viscosity problem, think so to make DS increase to 40%, and even 45% is high and still to keep stable operation be practicable.
Embodiment 8
Present embodiment has compared the inventive method and the ordinary method that is used for producing from the living starch Yellow Dent No.2 of dried ground corn form fuel alcohol or drinkable alcohol.
In the blue lid of 250ml flask, make thick W-Gum contact cold liquefaction and saccharification simultaneously with the 30%DS slurry of tap water preparation dry grinding corn and with the inventive method.This slurry is heated to 60 ℃ in the water-bath that magnetic stirs, use 30%HCl is with pH regulator to 4.5 and add CGTase T (75KNU/kgDS) and glucoamylase (500AGU/kg DS).After 48 hours, flask is cooled to 32 ℃ in water-bath.
Make 30%DS slurry liquefaction in advance in the conventional continuous processing of forming by pre-liquefaction vessel, jet-type pulp digester, flasher (flash) and liquefaction back container of dry grinding corn.Add genus bacillus α-Dian Fenmei (10KNU/kgDS) in the pre-liquefaction process under 70-90 ℃ and after about 85-90 ℃ liquefaction, add genus bacillus α-Dian Fenmei (20KNU/kg DS) in the process again.Under 115-120 ℃, carry out the jet-type boiling.Under stirring, magnetic carries out premashing by in the lid of the indigo plant in the water-bath flask mash being heated to 60 ℃.After using 30%HCl, add the glucoamylase that dosage equals 500AGU/kg DS with pH regulator to 4.5.After 48 hours, flask is cooled to 32 ℃ in water-bath.
In being installed, the indigo plant lid flask that charges into soybean oil of yeast lock directly ferments.Add the Bakers yeast (Saccharomyces cerevisiae) of the consumption equal 1,000 ten thousand/mL living yeast and the yeast nutrition thing of 0.25% urea form is joined in each flask.Handle all by carrying out in triplicate at every turn.
By the CO that measures as the flask of weighing in regular intervals of time 2Consume the monitoring fermentation.Use following formula to calculate L EtOH/100kg cereal dry-matter (DS) then:
