Abstract
The invention discloses a method for producing maltodextrin by using rice, which comprises the steps of soaking and grinding, rice milk concentration adjustment at 15 to 16Be, liquefying and deslagging, primary and secondary neutralization and filtration, ion exchange, concentration, drying, crushing and packing. The method overcomes the defects that the conventional maltodextrin uses corn, cassava and the like as raw materials, but the starch granules of the corn and the cassava are greater than that of the rice and are not favorable for gelatinization, and the process using the rice as a raw material is not mature enough. Through proper rice milk concentration and proper alpha-amylase additive amount, the mixture of filter aid and active carbon is adopted for neutralizing, decoloring and filtering; then ion exchange refining is carried out and proper amount of sodium metabisulfite is added, so the stability of sugar is improved; and the mixture is concentrated to certain concentration by using a quadruple effect falling film evaporator and a standard evaporator, and then the mixture is dried by using a vacuum low-temperature continuous dryer. The maltodextrin product has the advantages of crystal color, good liquidity, no peculiar smell, good solubility property, strong heat resistance, no brown stain, unique flavor and fragrance, strong digestive absorption capacity, low irritability and high biological value.
Description
Technical field
The present invention relates to the making method of maltodextrin, particularly a kind of method of producing maltodextrin with rice.
Background technology
At present, maltodextrin is generally with raw material production such as corn, cassavas, ripe not enough with rice as the technology of raw material, but because contained starch granules is about 2-10um, only greater than oat less than corn, cassava etc. in the rice, and a factor of the big minor matter decision gelatinization speed of starch granules, the little then easily gelatinization of particle, particle greatly then is not easy gelatinization, therefore be badly in need of having a kind of sophisticated be that the method for raw material production maltodextrin is come out with the rice.Maltodextrin is widely used in candy, malted milk, fruit tea, milk powder, ice-creams, beverage, can and other food, and it is the stopping composition and the thickening agents of varieties of food items.
Summary of the invention
At above problem, the invention provides a kind of method of producing maltodextrin with rice, the product maltodextrin color and luster that this method is produced is sparkling and crystal-clear, good fluidity, free from extraneous odour, solubility property is good, and thermotolerance is strong, not brown stain, have unique local flavor and fragrance, it is strong to digest and assimilate ability, hypoallergenic, the biological value height has the incomparable advantage of maltodextrin of other Starch Production.
Production method of the present invention may further comprise the steps:
(1) soak defibrination: behind the rice wash clean, adjust to pH value 8-9 with soda ash, defibrination after immersion for some time, fineness is more than 60 orders;
(2) size mixing: 15-16Be ° of the concentration of sizing mixing, transfer pH value 5.8-6.0 with soda ash or hydrochloric acid, add calcium chloride 0.2-0.5 kilogram by dry-matter per ton, add a-amylase 400-450mL again, stir and sent into liquefaction transfer jar in 30 minutes;
(3) slag is taken off in liquefaction: adopt injector liquefaction, one time injection temperature 105-110 ℃, enter pressurize and keep jar pressurize about 5 minutes, the flash distillation cooling is sent into continuous liquefaction streamline column for 95 ℃, guarantee the albumen flocculation, liquefaction thoroughly, 60-90 minute laminar flow time, detect DE value and reach 12%-18%, iodine try into brown or iodine liquid true qualities after, pass through the second spraying device again, the controlled temperature 125-130 ℃ of enzyme that goes out kept jar pressurize about five minutes in pressurize, 115-120 ℃ of flash distillation cooling after taking off slag transfer jar and cooling to 95-100 ℃ with the logical cold water of coil pipe, filtered and taken off slag, syrup is cooled to the 80-90 degree with plate-type heat exchanger, delivers to neutralization tank one time;
(4) once neutralization is filtered: after one time neutralization tank receives the sugar material, survey pH value, transfer to 4.4-4.8 with hydrochloric acid or soda ash, temperature is controlled at 80-90 ℃, to contain proteic substance more because of syrup, filtration difficulty is pressed 5kg/ ton dry-matter and is added flocculating aids, stirs 15 minutes, add gac 3-4kg behind the filtering layer to be formed again, stirred 20 minutes, sampling is filtered with test paper, and color and luster can filter when reaching water white transparency or little yellow;
(5) in the secondary and filter: after the secondary neutralization tank receives the sugar material, add gac 3kg/ ton dry-matter, keep 80-90 ℃ of temperature, stirred 30 minutes, adopt airtight filter to filter, the feed liquid requirement is as clear as crystal, no foreign matter, the visible impurity of no naked eyes;
(6) ion-exchange: use from handing over post to exchange the sugar material, discharging is clarified, water white transparency, free from extraneous odour, transparence 〉=95%, pH value 4.0-6.0, adding Sodium Pyrosulfite saturated solution 400-500mL in sugar material after handing over;
(7) concentrate: adopt the evaporation of quadruple effect falling film evaporator, evaporative concn adopts the standard pan evaporative concn to 81%-83% to 71%-73% more for the first time;
(8) drying: select vacuum and low temperature continuous drier drying for use, vaporization temperature is no more than 80 ℃, finished product moisture content≤6%;
(9) pulverize: broken with the stainless steel abrasive dust, fineness is controlled at the 100-120 order;
(10) packing: adopt automatic packing machine between sterile packed, to pack.
The present invention has following advantage: the present invention guarantees gelatinization effect in liquefaction process by suitable Rice ﹠ peanut milk concentration and suitable a-amylase addition, in time knocks out amylase activity by secondary liquefaction again, guarantees that the DE value is at 12-18%; For solving the sugar material because of containing the problem of the more filtration difficulty of albumen, adopt in the mixing of flocculating aids and gac and decolorization filtering, sugar material after guaranteeing to filter does not contain the albumen composition, refining and add an amount of Sodium Pyrosulfite by ion-exchange again, improve the stability of sugar material, be concentrated into finite concentration with quadruple effect falling-film evaporator and standard pan, use vacuum and low temperature continuous drier drying again.The maltodextrin color and luster that the inventive method is produced is sparkling and crystal-clear, good fluidity, free from extraneous odour, solubility property is good, and thermotolerance is strong, not brown stain, have unique local flavor and fragrance, to digest and assimilate ability strong because of it, hypoallergenic, the biological value height has the incomparable advantage of maltodextrin of other Starch Production.The industry such as basic material, cold drink industry, ready-to-eat industry and chemical industry, weaving, leather that is widely used in infant or baby food and extraordinary crowd's food.
