Abstract
The invention belongs to the technical field of food additive, and specifically relates to a production method of high-grade maltodextrin. According to the invention, refined corn starch is adopted as a raw material, and processes such as material blending, jet liquefaction, flash evaporation, filtering, primary decolorization filtering, secondary decolorization, ion exchange, evaporation concentration, spray drying, and the like are carried out, such that MDl00 high-grade maltodextrin with a liquefaction DE value smaller than 10 is produced. With the method, requirements of current food and medicine production upon high-grade maltodextrin can be satisfied.
Description
Technical field
The present invention relates to a kind of production method of high-grade maltodextrin, belong to technical field of food additives.
Background technology
Maltodextrin also claims water-soluble dextrin or enzyme process dextrin.It is to make raw material with each kind of starch, transforms through acid system, enzyme method technique low degree control hydrolysis, purifies, and drying forms.Because it is low that maltodextrin has sugariness, free from extraneous odour, easily digestion, low-heat, solvability is good, and fermentable is little, filling effect is good, be difficult for the moisture absorption, thickening property is strong, and carrier is good, good stability, the characteristic that is difficult to go bad is widely used in industries such as beverage, frozen product, candy, oatmeal, milk-product, medicine, healthcare products, also can be applicable in weaving, daily use chemicals, the medicine production.
The production method of maltodextrin mainly contains acid system production technique and enzymatic production process.Acid system production is mainly adopted in early stage maltodextrin production, the major defect of acid system production technique is the distribution of the uncontrollable product hydrolysis of the producer, and the maltodextrin of producing when leaving standstill because the macromolecular gathering of long-chain linear, be easy to wear out, muddiness, simultaneously can't reduce bad color and luster and the local flavor that side reaction causes.Compare technology with acid system and compare, the starch liquefacation product that enzymatic production process is easier to produce the starch hydrolysis production of low-conversion or is suitable for further handling, and also side reaction is few, and mild condition is easy to control to have at present replaced by enzymatic production process.Chinese patent CN101429534A discloses a kind of production technique of maltodextrin, this patent is the raw material production maltodextrin with corn or rice or potato class, weak point product DE value can't adapt in current infant or baby food and the pharmaceutical production demand to high-grade maltodextrin still between 14-20 and unstable product quality.
Summary of the invention
For overcoming above deficiency, the invention provides a kind of production method of high-grade maltodextrin.The present invention is a raw material with refining W-Gum, produces the MDl00 top grade maltodextrin of liquefaction DE value＜10 by batching, steam ejection liquefaction, flash distillation, filtration, decolorization filtering, secondary decolourization, from operations such as friendship, evaporation concentration, spraying dryings.
The present invention adopts following measure to realize:
A kind of production method of high-grade maltodextrin is characterized in that may further comprise the steps:
(1) batching: add refining W-Gum and water thorough mixing in material-compound tank, transferring starch concentration is 15-20 ° of Be, adds Na
2CO
3Transfer PH to 5.0-7.0, add 0.15%(dry-matter meter) calcium chloride, as diastatic protective material and activator, add high temperature resistant a-amylase 0.4-1.0L/t dry starch at last;
(2) steam ejection liquefaction: pre-thermal sprayer and laminar flow jar to 100 ℃, carry out steam ejection liquefaction then, one time the steam ejection liquefaction temperature is 100-110 ℃, enters laminar flow jar insulation 90-120 minute after the feed liquid cooling of coming out from injector, and temperature maintenance is at 95-97 ℃; Carry out second spraying then, temperature is controlled at 110-145 ℃, and keeps the 5-10 minute enzyme that goes out in high temperature is kept jar;
(3) flash distillation: feed liquid is reduced to 70 ℃-90 ℃ through temperature behind the flash tank, and adjusts the pH value to 4.8-5.0;
(4) filter: after feed liquid was reduced to 70 ℃, filtrate was through the flame filter press filter cleaner, and filter residue can be processed into feedstuff raw material and be used in field of fodder.
(5) once decolour, filter: in bleacher, add after gac 4-8kg/t dry starch stirs 30 minutes after-filtration of 80 ℃ of insulations;
(6) secondary decolourization: in the secondary decolourization jar, after adding gac 2.5-5kg/t dry starch stirred, 80 ℃ of insulations were sloughed one in 15 minutes and are taken off unclean pigment;
(7) from friendship: adopt highly acidic cation-weakly-basic anion-storng-acid cation exchange resin, temperature 40-50 ℃, remove metal-salt and pigment in the liquid;
(8) evaporation concentration: imitate plate-type evaporator from handing over back liquid to enter eight, concentration is concentrated into 50-60%;
(9) spraying drying: concentrate back liquid and adopt the high pressure homogenizer pressurization, get product to the drying tower spraying drying.
Process innovation point of the present invention:
1, adopt special steam ejection liquefaction system, liquefaction thoroughly, protein and starch good separating effect, the albumen flocculating effect is good.Not only make yield improve (〉=89%), and solved a difficult problem-filtration problem of Production by Enzymes maltodextrin maximum;
2, heightened the concentration of starch milk, had an original 15-17 ° Be to heighten, because of feed concentration improves to 20-22 ° of Be, the water consumption of feed liquid is reduced, the water coolant of required consumption and steam are also reduced in process of production, reduce the time that feed liquid is transported in pipeline simultaneously, reduce power consumption; 3, liquefaction evenly, under the qualified preceding topic of iodine examination, the liquefaction DE value that may command is lower, highly difficult, the high-grade maltodextrin that price is higher of production MDl00; 4, reduce facility investment, improve plant factor.Suitably adjusting process route and processing condition adopt a production line, both can produce maltodextrin, but the bigger dextrinosan of the difficulty of production spraying drying again.
