Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, the low sugariness of a kind of novelty, low in calories, high-nutrition food raw material, the starchiness agricultural-food such as starch or corn, potato class of take are raw material, the pure carbohydrate of the class being transformed through amylase low degree between starch and sugar, its dextrose equivalent value (calling DE value in the following text), lower than 20, only contains a large amount of polysaccharide.
The present invention is achieved in that a kind of production technique of maltodextrin, and the production technique of maltodextrin has three kinds of acid system, acid-enzyme hydrolysis method and enzyme process.Acid system filtration difficulty wherein, product poorly soluble, acid-enzyme hydrolysis method effect is better, but is unwell to direct employing starchy material (as corn, potato class), adopts enzyme method technique the most applicable.Its production technique is: the liquefaction → high temperature of starch → sizing mixing → for the first time go out the enzyme → enzyme that liquefies for the second time → go out decolouring → filtration → ion-exchange → concentrated → spraying dry → product.Technology point is as follows: (1) starch is sized mixing, gelatinization is because the crystalline texture of starch granules is stronger to the resistibility of enzyme effect, can not make enzyme directly act on starch, so first with hot water by the starch milk of starch furnishing 30-32%, and make its abundant water-swelling, gelatinization.Regulate pH value to 6.2-6.4 simultaneously, add 0.5-1.0% calcium chloride, to improve diastatic thermotolerance.(2) this is the critical process of production maltodextrin to transform (liquefaction), because the maltodextrin low conversion product that is starch, DE value is controlled between 10-20, viscosity is higher, bad if liquefaction is controlled, and can bring many difficulties to later process, cause yield low, poor product quality.For this reason, first by α-amylase by the starch slurry DE value 2-5 that liquefies, be warmed up to rapidly 140 ℃, protein-based impurity is condensed, cool to 88-90 ℃, the more enzyme-added DE value needing that is transformed into, such conversion fluid filtering property is good.(3) refining 1. filtration: the throw out in above-mentioned conversion fluid, with Filter Press, general available diatomite etc. are made flocculating aids, to accelerate filtration velocity.This procedure can be removed the impurity such as fiber, protein substance and lipid material, obtains the filtrate of clarification.2. decolouring: filtrate gives purifying treatment with gac, the consumption of gac is 0.5% left and right of filtrate dry-matter, the decoloring ability of gac different pH values in the scope of pH4-6 is basic identical, the liquid glucose that decolours under lower pH value be heated color and luster increase few, so decolouring operation can adjust pH to 4.5-5.0.Bleaching temperature is general adopts 80 ℃, keeps 30 minutes.3. from friendship: in order further to improve the quality of products, spent ion exchange resin is removed salt.(4) evaporation (concentrating), in vacuum evaporating pot, can adopt standard type evaporating pot, carries out just steaming or being directly concentrated to 76% concentrated solution.(5) a kind of dry reasonable method of spraying is that the maltodextrin of purifying is just steamed to concentrated solution through heat exchanger heats to 110 ℃, by high-pressure pump, through nozzle, spray in kiln and arrive moisture content below 3% with the warm air contact drying of 150-200 ℃, obtain white powder, this product is soluble in water, and transparency is high.(6) finished product packing can adopt double-layer food plastics bag or accompany the double-deck kraft bag packing of moisture-proof barrier.The hydrolytic process of maltodextrin makes starch molecule from large to small, is actually the mixture of maltose, fructose, dextrin etc.Because dextrin ratio is large, dextrose equivalent value reduces relatively, so its sweet taste is faint, thickening property is strong, and fermentable is little.Therefore, maltodextrin has following features: solvability is good, energy is water-soluble, therefore can make thickening material in beverage, improves the thickness sense of beverage; Water absorbability is low, particularly makes powdery, particulate solid beverage (comprising local flavor soup stock) is difficult for the moisture absorption, prevented from caking; A little less than reducing sugar, the brown stain in the time of can reducing food-processing; Good fluidity, storage is got conveniently, easily mixes; Good film-forming property and froth stability are strong, can give the certain form of food and viscosity, and can suppress the crystallization to granulated sugar; Digestion and absorptivity are strong, should make patient, baby, arsenic, are suitable for doing the patients' such as coronary heart disease, obesity, sclerosis low-heat dietetic food.
