Abstract
A kind of high-carbon alcohols non-silicon defoaming agent and preparation method thereof, the antifoaming agent as mass fraction, include 5 35% oil phases, 3 15% emulsifiers and 1 3% thickener；Wherein, oil phase includes atoleine, n-octyl alcohol, stearic acid and octadecyl alcolol, emulsifier includes combination one kind or two or more in Distilled glycerin monostearate, sorbitan monostearate, sucrose fatty ester, and thickener is microcrystalline cellulose and/or sodium carboxymethylcellulose.The present invention provides a kind of safety, cheap, the good food-grade antifoaming agent of non-silicone of defoaming, to meet the production needs of soybean protein processing enterprise using high-carbon alcohols material with phase inversion mode.
Description
Technical field
The present invention relates to a kind of high-carbon alcohols non-silicon defoaming agents and preparation method thereof, are processed available for soybean protein isolate,
Belong to technical field of fine.
Background technology
In the production of existing soybean protein, a large amount of foams are often generated, influence end product quality and production capacity, most
Simple effective method is to achieve the purpose that control foam using antifoaming agent.Existing market antifoaming agent is of numerous names, by chemical group
Into alcohols, fatty acid, amides, polyethers, polysiloxanes etc. can be divided into；According to the difference of component, organosilicon can be divided into and disappeared
Infusion, antifoaming agent of non-silicone.
Organic silicon defoamer is equipped with suitable quantity of water by silicone grease, emulsifier, waterproofing agent, thickening agent etc. and is formed through machinery emulsification.
Its main feature is that surface tension is small, high surface activity, defoaming power is strong, and dosage is few, at low cost, wherein dimethyl silicone polymer and gas phase
Silica can all cause silicon residual quantity high.Silicone content as only liquefaction company of Japan requires is less than 40ppm, and external is same
For row product silicone content between 100-250ppm, home products silicone content is between 100-400ppm, far above only liquefaction public affairs
The standard of department.Therefore, antifoaming agent of non-silicone must be selected in production, does not add antifoaming agent even to meet the requirements, but do not add
Add antifoaming agent that can not eliminate the harmful effect of foam.In the product introduction of fewer companies, in order not to adding organic silicon substance and
Insecurity substance, such as triethanolamine, aluminum stearate are used.With the promotion of awareness of safety, given birth in soybean protein isolate
During production, higher requirement also proposed to the safety of antifoaming agent.The research of novel antifoaming agent is further promoted to open as a result,
Hair.
If CN 102895805A disclose a kind of production method of non-silicon defoaming agent, this method is with White Mineral Oil, white carbon,
Polyethers, polyether polyol, castor oil prepare ointment, add in from after stirring evenly newborn silicone oil, tributyl phosphate, add in water phase inversion,
Thickener is added after phase inversion to be made.CN 1762532A disclose a kind of water phase system non-organic silicon defoaming agent, are applied suitable for papermaking
Cloth and the defoaming of copy paper plain boiled water.The higher aliphatic of use, higher aliphatic polyethers, nitrogen-containing polyether, aliphatic ester, hydrophobic particles and
Mineral oil body, emulsifier and water mainly solve high temperature emulsification and antifoaming agent performance and increase the problems such as decaying, tool with temperature
There is the features such as safe and efficient, economic.Food additives provide polyoxyethylene propylene oxide glycerine using standard GB 2760-2014
Ether (bubble enemy) and polypropylene glycerol aether (glycerin polyether GP) are the antifoaming agent for zymotechnique, such antifoaming agent generally existing
Use condition is by temperature limiting, and the defects such as brokenly bubble efficiency is low.
In addition, research finds that the fatty acid ester compounded object of higher alcohols also can preferably be used for disappearing in soybean protein processing technology
Infusion.If CN 103476267A disclose a kind of food antifoaming agent, this method use diglycerol with specific composition with it is pungent
Acid and/or the Esterification product of certain herbaceous plants with big flowers make its defoaming effect in a low temperature of 0-20 DEG C suitable with organic siliconresin antifoaming agent performance.But
Its poor dispersion in water of antifoaming agent made from this method, leads to its limited defoaming capacity and seriously restricts speed of production and effect
The raising of rate influences product quality and after-processing technology etc..
Invention content
For this purpose, one of the objects of the present invention is to provide a kind of high-carbon alcohols non-silicon defoaming agent, to overcome more than organosilicon
Antifoaming agent safety and the weakness of oil phase antifoaming agent.The present invention provides one kind using high-carbon alcohols material with phase inversion mode
Safety, cheap, the good food-grade antifoaming agent of non-silicone of defoaming, to meet the production needs of soybean protein processing enterprise.
A kind of high-carbon alcohols non-silicon defoaming agent as mass fraction, includes 5-35% oil phases, 3-15% emulsifiers and 1-
3% thickener；
Wherein, oil phase includes atoleine, n-octyl alcohol, stearic acid and octadecyl alcolol, and it is sweet that emulsifier includes distillation monostearate
One kind or two or more combination in grease, sorbitan monostearate (sorbester p18), sucrose fatty ester, preferably distillation are single
Tristerin, sorbitan monostearate (sorbester p18) and sucrose fatty ester, thickener for microcrystalline cellulose and/or
Sodium carboxymethylcellulose, preferably microcrystalline cellulose and sodium carboxymethylcellulose.
Preferably, the mass ratio of atoleine in oil phase, n-octyl alcohol, stearic acid, octadecyl alcolol is 1-10:0.2-2.5:
0.2-1.5:1。
Preferably, Distilled glycerin monostearate in emulsifier, sorbitan monostearate, sucrose fatty ester
Mass ratio is 0.2-5:0.2-5:1.
Preferably, emulsifier is the 8-10% of oil phase quality.
