Description
Technical field
The present invention relates to the sterilising medium for the packing that are used as packaging for foodstuff, this medium comprises the aqueous system of hydrogen peroxide and dispersant additives composite.The invention still further relates to the method for this sterilising medium of preparation, sterilization is as the laminate wrapping material of packaging for foodstuff or the method for its container, and is being used for the use of sterilization as the sterilising medium dispersant composition that comprises hydrogen peroxide of the packing of packaging for foodstuff or container.
Background technology
In the production of sterilized packaged food, a plurality of factor interactions are in order to obtain the food product that for a long time preservation and taste and nutritional quality can not descend.The degree that germ can not breed in the longer-term storage process of importantly this food product being sterilized, and this product is packed into this package carries out under the germ-free condition in clean machine and in the clean environment, and this package itself can keep this product not to be subjected to for a long time the impact of ambient moisture, light, oxygen and bacterium.Certainly, the most important thing is that these packing or package are aseptic, namely do not have germ when this food is filled into wherein.The sterilization of packaging machine, packing to be filled or package can be various different modes realize, for example by applying chemical disinfection liquid or gas phase medium on surface to be sterilized, by UV light or the combination by electron beam irradiation or these methods.Certainly, at first thoroughly clean and utilize aseptic water washing also greatly to help in packaging machine, to obtain gnotobasis.
The disposable use packing container that is used for liquid and heavy body supping is often made by packaging laminate, and this ply wood comprises sandwich layer and outmost liquid-tight, the heat-sealing polyolefin layer of Paper or cardboard.Common this packing container is with trade mark Tetra Brik
Or Tetra Classic
Introduce to the market, and be mainly used in such as liquid foods such as milk, fruit juice.Packing in these known packing containers are ply wood normally, and it comprises bulk core layer and the outer, liquid-tight layers of Paper or cardboard.In order to make this packing container light tight and airtight, particularly airtight to oxygen, the purpose that for example is used for aseptic packaging and juice packages, the ply wood that is used for these packing containers generally is provided with at least one extra layer, the most frequently used aluminium foil, it be also so that these packing can come heat seal by the conduction heat-sealing, this be obtain mechanically firm, liquid-tight in these container manufacturing processs and be tightly connected or seam fast and effective technology.Inboard at this ply wood, namely will face a side of the contents of the container of being made by this ply wood, an outermost layer will be arranged, use this aluminium foil on it, this outermost, inboard layer are comprised of a plurality of sublayers (part layer), and it comprises sticky polymers and/or polyolefin.
This packing container generally relies on that the prefabricated embryo material by coiled material or packing forms, the wrapping machine manufacturing of filling and sealed package.For example, by coiled material, packing container is made like this, that is, being bonded to each other by two longitudinal edges with this coiled material forms tubulose again in overlapping joint portion.Desired liquid food products filled by this pipe and the repetition transverse sealing by this pipe is divided into independent package, and these are sealed in below the height of contents in this pipe at a distance from each other.This package separates by cutting in these transverse sealings, and by providing needed geometric construction along ready broken line folding and forming in these packing, generally is parallelepiped or tetrahedron shape.
Form and before product inserted this pipe, this coiled material was usually by having the groove of liquid disinfectant at pipe.The roller that is called squeegee (squee-gee) squeezed away the remnants that remove this sterilised liq by the remnants with sterilised liq from this coiled material before this pipe utilizes hot filtrated air drying.Compared with just by guiding this coiled material to flood this coiled material by the dark bath of sterilising medium, the additive method of this packaging material tube of sterilizing be utilize roller to packaging material web spraying, gas phase liquefaction or, to apply the most at large, with this uniform liquid be applied to the surface of this packaging material web.
A kind of disinfectant very commonly used is hydrogen peroxide (H
2O
2), it is applicable to liquid phase or gas phase medium.Under normal circumstances, for the application in the food industry, hydrogen peroxide is as the aqueous system of the about 35wt% of concentration, but higher concentration also is feasible, for example up to 50wt%.Use other disinfectants toward contact, such as peracetic acid.
The degree that Disinfection Effect can arrive depends on this sterilising medium well-distributed ability and concrete surperficial wetting behavior on whole surface to be sterilized.When surface tension was too high, this sterilising medium formed larger drop and can not evenly scatter on this surface.Two main problems appear in the result of this situation.First is that disinfection efficiency is low, because disinfectant does not act on whole surface and regional considerably less between that because used too much sterilising medium in the zone of larger drop.Second Problem is that the remnants of sterilising medium after sterilization will be retained on this surface, because be difficult to remove satisfactorily larger drop in the high production speed situation in wrapping machine.
These two problems are interrelated, because hydrogen peroxide will help the evaporation of drop in drying in better distribution on the coiled material, and therefore cause residual peroxide less in package.
These two problems are more remarkable in high-speed production, because this disinfectant only has the minimum time to be worked in surface to be sterilized and very fast removal before filling food product like this.When surface to be sterilized was level and smooth especially and glossy, this problem was also remarkable especially, such as outermost some the film character as packaging laminate.For example, high-viscosity products needs this viscous foodstuff product can not stick to the outermost material surface, namely directly towards the side of packing container the inside, in order to promote emptying of this package.Nature, this disinfectant yet can not spread and remain and evenly be coated on this " non-adhesion " surface.And, have so non-wetting behavior as some film character (being used for covering the longitudinal sealing of this package the inside) of the inside band (inner strip) that is attached to innermost layer.Although this disinfecting process can be remained under the tight control and obtain abundant and enough sterilizations with the disinfectant with hydrogen peroxide medium that utilizes current use, but need to be for the wider operation window of correlation parameter, such as temperature and the concentration of speed of production and contact time, disinfectant.
In order to remedy to a certain extent these problems, knownly for a long time aqueous hydrogen peroxide solution and nonionic wetting agent (are called " Tween
TM20 ", carbowax 20 sorbitan laurates (polyethylene glycol 20sorbitan monolaurate)) mix.Obtain certain diffusion effect, but it stays improved space, particularly for high-speed production and when the variation in the technological condition is difficult to control.
By EP1384670, in containing the hypochlorous water-soluble thimerosal of chloro disinfectant, use wetting agent as can be known, i.e. fatty acid value or lecithin.Yet, only have when sterilization method also comprises heat sterilization, just might obtain in short contact time the sufficiently sterilised effect.
From US5,858,933 use chemical modification lecithin bound fat ester as the lubricating additive that utilizes clay coated paper coiled material in the manufacturing process as can be known, cause the coating quality that improves owing to the viscosity control that improves, the flowing power that improves and coating problem still less (such as calcification, speckle, the accumulation of salt in the surface soil etc.).These attributes depend on these particulates and pigment in this application composition, disperse have how good.
From US4,200,551 further improve the dispersiveness of non-modified natural lecithin as can be known by increasing nonionic emulsifier.
Yet, also do not imagine so far these discoveries about lecithin compound be developed as suitable dispersing agent adding ingredient for water-soluble disinfectant with hydrogen peroxide medium.
Summary of the invention
So, the objective of the invention is to overcome or relax the problems referred to above.
Total target of the present invention provides the sterilising medium based on hydrogen peroxide, and it has improved at lip-deep diffusion attribute to be sterilized.
So, the sterilising medium that provides based on hydrogen peroxide is provided, it is more effective and can improve the robustness (robustness) of this sterilization process, and is namely insensitive for the variation of technological condition, and therefore also can work well in the higher speed of production of wrapping machine.More specifically, its objective is the sterilising medium that provides based on hydrogen peroxide, it has improved Disinfection Effect.The specific purposes of the preferred embodiments of the present invention provide the sterilising medium based on hydrogen peroxide, and it has wetting about sterilising medium and Disinfection Effect consumption aspect the best.
The further specific purposes of the present invention provide the sterilising medium based on hydrogen peroxide, and its surface after sterilization stays the residual volume of minimizing.
The another further purpose of the present invention provides the sterilising medium based on hydrogen peroxide, and it also works well for level and smooth and glossiness surface with low moisturing capacity.
According to the present invention, the sterilising medium based on hydrogen peroxide that defines by claim 1 reaches these purposes.The preferred embodiment of sterilising medium of the present invention limits in claim 2-11.
Therefore, according to the present invention, reach these purposes by the sterilising medium that comprises aqueous hydrogen peroxide solution and dispersant additives composite, said composition comprises the cmpd of selecting from the group of lecithin and chemical modification lecithin, and further comprises nonionic emulsifier.
Hydrogen peroxide becomes the most frequently used disinfectant because of its outstanding bactericidal effect, relatively low cost and in the health and safety characteristic aspect the food applications.Concentration can be used for this invention up to the aqueous hydrogen peroxide solution of 50wt%, and for the application of food industry, is available up to the about solution of 35wt%.Preferably, according to the present invention, in sterilising medium, use 30 to 40wt% concentration, most preferably 35wt%.
Lecithin is thought better tolerance and nontoxic inhibiter.It is used for human edible by the approval of U.S. food and Drug Administration, state be " GenerallyRecognized As Safe " (GRAS), and also ratified as food additives by EU.In biochemistry, lecithin is typically used as the synonym of phosphatid ylcholine, and phosphatide is the main portion of the phosphatide fragment that can separate with yolk or soya bean.Commercial lecithin is the compound of phosphatide in oil.Phosphatid ylcholine, phosphatidyl-ethanolamine and phosphatidic acid from the main phosphatide in the lecithin of soybean or sunflower oil.In order to adapt to the performance of lecithin, they can chemical modification.
Being used for suitable chemical modification lecithin of the present invention generally can be dispersed in water and usually have a iodine number (I.V.) less than 50 than natural lecithin is easier.This iodine number is relevant with the unsaturated number of ethene in the related substances molecule.This chemical modification is introduced hydrophilic substituent in this fatty acid ester group usually, and it is transferred so that this lecithin is more hydrophilic.Preferably, this chemical modification lecithin is hydroxylation or acetylizad lecithin, the acetylation lecithin of the hydroxylated lecithin of saponification or saponification or its compound.Other chemical modification lecithin can be by obtaining with enzyme reaction, such as lipase.Most preferably, be hydroxylated lecithin according to chemical modification lecithin of the present invention.
Yet, find that unexpectedly unmodified, natural lecithin also can very well disperse and work in aqueous hydrogen peroxide solution.Probably, this is because chemical reaction or interaction between unmodified lecithin and the aqueous hydrogen peroxide solution cause, and so initial unmodified lecithin chemical modification that becomes in fact at last probably has the hydroxyl in the picture hydroxylated lecithin.
Although lecithin compound is to a certain extent as coming work for the independent dispersing agent that contains the aqueous hydrogen peroxide solution sterilising medium, but find surprisingly, in the time of in being combined in the dispersant composition with non-ionic emulsifying agent, this dispersibility based on the sterilising medium of hydrogen peroxide significantly improves.Preferably, this nonionic emulsifier is polyethyleneglycol derivative or the polyethyleneglycol derivative of partial fatty acid ester or the compound of hexitan or these emulsifying agents of fatty glyceride.The polyethyleneglycol derivative of partial fatty acid ester and the representative illustration of hexitan are POE (carbowax) 20 anhydrosorbitol monostearates, POP (polypropylene glycol) 20 anhydrosorbitol monostearates, POE20 anhydrosorbitol tristearate, POE10 anhydrosorbitol distearate, POE15 dehydration sweet mellow wine monopalmitate, POE10 dehydration sweet mellow wine two myristinates, POE20 anhydrosorbitol dioleate, the POE20 dehydrating sorbitol monooleate, POE20 anhydrosorbitol trioleate, POE20 galactitol monostearate, POE20 galactitol dioleate, POE30 anhydrosorbitol monostearate, POE20 monolaurate, the POE20 sorbitan-monopalmityl ester, POE5 dehydrating sorbitol monooleate etc.
The monoglyceride of fatty acid polyglycol ethylene glycol derivative and diglyceride are according to following formula
(I)CH2(r2)CH(R3)CH2(R4)
Wherein (R2), (R3), and (R4) at least two be selected from the fatty acid ester with at least 12 carbon atoms and the polyalkylene glycol moiety that is expressed from the next
-(-OCH2CH(Y)-)n-OY
Wherein n represents to repeat the mean of carbowax unit, and Y is hydrogen atom or methyl and the remaining R1 of formula (I), and R2 or R3 partly are hydroxyl, polyalkylene glycol moiety or fatty acid ester.
More preferably, nonionic emulsifier is the alkoxylate sorbitan fatty ester, most preferably is carbowax 20 sorbitan fatty esters.An example that preferably, works well is carbowax 20 sorbitan monolaurates, is also referred to as " Tween
TM20 ".
Have been found that sterilising medium should preferably comprise 0.1wt% to non-modification or the chemical modification lecithin of 0.4wt%.Be higher than 0.4wt%, sterilising medium becomes oily and more is difficult to when drying from disinfecting surface removal.Be lower than 0.1wt% lecithin, consumption or the absorption of disinfectant (being hydrogen peroxide) became low, and namely to be sent to the effect of surface to be sterilized and sterilization too poor unreliable for very few hydrogen peroxide.
Therefore further this lecithin compound is mixed with nonionic emulsifier, improves diffusion, and preferably, and the concentration of nonionic emulsifier should be that the 0.1wt% of sterilising medium is to 0.3wt%.Best, this sterilising medium comprises the nonionic emulsifier of 0.2wt% to the chemical modification lecithin of 0.3wt% and 0.1wt% to 0.2wt%.Absolute preferably and the best preferably, this sterilising medium comprises that the chemical modification lecithin of about 0.3wt% and 0.1wt% are to the nonionic emulsifier of 0.2wt%.In a different manner statement, this dispersant additives composite should most preferably comprise the nonionic emulsifier to the chemical modification lecithin of 75wt% and 25wt% to 40wt% with the total weight 60wt% of dispersant composition.
According to a further aspect in the invention, pass through according to the sterilising medium based on hydrogen peroxide of the present invention: at first with weight ratio 1: 5 to 1: 20, preferably at about 1: 10, add the dispersant additives cmpd of from the group of lecithin and chemical modification lecithin, choosing to aqueous hydrogen peroxide solution or deionized water, stir this compound to obtain stable emulsion, add the water-soluble dispersing agent lecithin emulsions that obtains like this to the disinfectant with hydrogen peroxide medium aqueous system, add nonionic emulsifier and stir to obtain stable disinfectant with hydrogen peroxide medium at last in certain stage.Which stage to add this nonionic emulsifier in is not very important for net result, but preferably, at first nonionic emulsifier is added to this dispersant additives lecithin emulsions to form the dispersant additives composite.Perhaps, the stable aqueous emulsions form that this nonionic emulsifier can be independent directly is added to this aqueous hydrogen peroxide sterilising medium.
According to a third aspect of the present invention, describe and a kind ofly sterilize on the surface to be sterilized as the packing of packaging for foodstuff or the method for container by sterilising medium of the present invention is applied to.According to a preferred embodiment of the present invention, by being immersed the sterilised liq groove, these packing apply sterilising medium.According to another preferred embodiment of the present invention, by transfer roller the liquid disinfection medium is sent to this package material surface from the sterilised liq groove and applies these packing and apply this sterilised liq.Again further embodiment according to method of the present invention applies this sterilising medium by this liquid disinfection medium is sprayed on package material surface to be sterilized.

Fig. 4 is shown schematically in the wrapping machine, how by a side that sterilised liq is sprayed on the laminated coiled material sterilising medium to be coated on this coiled material, and in due course, use subsequently UV radiation exposure surface to be sterilized, this wrapping machine is generally to be used for making the freezing ESL (long preservation of plan, Extended ShelfLife) type of the package of storage
Fig. 5 a to 5j illustrates by the standard according to the method for top Fig. 2 and applies the UV photo that roller is applied to distribution or the diffusion of this sterilising medium liquid on the packing, and this sterilising medium liquid has the film formed surface to be sterilized of very level and smooth porous.This UV picture is by with fluorescer (namely
) be included in this sterilising medium and obtain.
When Fig. 6 a, 6b and 6c illustrated the sterilization process of describing about Fig. 2 above using, this sterilising medium was on the impact of sterilised liq surplus.
The specific embodiment
Therefore Fig. 1 a illustrates the principle of this packing and sterilization process 10, and wherein guiding packing veneer roll material bathes 12 by the liquid disinfection medium is dark in wrapping machine, and this wrapping machine is to be commonly used to produce Tetra Brik
That packs is the sort of.Usually, time length (sterilizing in this package material surface in the meantime) is that this packaging material web is immersed in the total time in the sterilised liq groove.Almost after this coiled material leaves from this groove, drain by the device that is called squeegee 13, this roller bearing pushes away liquid from this coiled material, and subsequently by dry this coiled material of the filtrated air of heat.When by this technique sterilization, there is not actual wetting problem, because surface to be sterilized is immersed and the whole direct contact liq long enough time.Yet, also can exist: this coiled material by this rubber cylinder after on this surface drop have muchly, and have when therefore dry and manyly remove easily, and the problem of sterilised liq surplus on the sterilization rear surface that causes thus.After sterilizing operation, this web shaped becomes pipe 14, and filling liquid food product 15 seals and is divided into independent package 16.
In Fig. 1 b, illustrate for continuous high speed packing Tetra
The example of the wrapping machine 10b of Aseptic package.With this stratiform packaging material web at the rear portion of this machine under spool 11 volumes, and just guide this coiled material to pass through sterilised liq groove 12 applying thermoplastic polymer's longitudinal sealing cover fillet (cover strip) 11 ' afterwards.Dry and evaporate after this sterilised liq, this coiled material is formed pipe 14, its longitudinal sealing and similar in same operation the pipeline 15 by entering this pipe top ' filling 15 food products, at this pipe of surface underneath transverse sealing of the food product of filling, and cut away 16 independent packages and last folding and this package formed their final form 17.
In Fig. 2, use sterilization process 20, according to this technique, this package material surface can directly not contact the part that this liquid surpasses total " time length ", namely this sterilising medium acts on this lip-deep time, namely this packaging material web immerses the lasting limited time of groove, is called shallow bath.In the machine that uses this decontamination system, by being immersed shallow bath 22, packaging material web 21 carries out test as mentioned below.Rubber cylinder 23 is removed the sterilised liq residue from this coiled material, then this web guide is passed through heating chamber 25.For efficient and the minimizing sterilising medium surplus that improves this sterilization process, this system is equipped with the device that is named as bubble roller (blister roller) 24 that has especially rough surface in heating chamber 25, it is decomposed into less liquid with the drop on this package material surface.In order further to raise the efficiency, extra heating and drying unit 26 with other thermal source and air stream can be connected to this heating chamber 25.
In Fig. 3, use sterilization process, be coated with sterilising medium according to this package material surface of this technique by the roller effect, namely transfer roller 33 is sent to packing 31 surfaces with the liquid disinfection medium from shallow bath 32.The surface that applies is dry by the heater element (not shown) subsequently.When applying sterilising medium according to the specially designed transfer roller of this technology utilization, only compare this coiled material is immersed liquid, can obtain more uniformly surface coating.Seen when lecithin is used alone as dispersant additives the additive Tween traditional with independent use
TM20 compare, and obtain passing through the better sterilising medium diffusion of this package material surface, and in the later case this dispersion is also bad.
By the sterilization method of Fig. 4, purpose is to be manufactured on to deposit the packing container that the subject word aspect has low requirement, as being used for the package of refrigeration ELS storage.Yet aseptic sterilisation methods also may comprise sterilised liq is sprayed on the package material surface to be sterilized.Packaging material web 41 is guided through chamber 44, wherein rely on nozzle 42 sterilised liq to be sprayed on the whole surface of this coiled material, and afterwards this web guide is passed through UV lamp 43, be used for utilizing the same surface of UV irradiation, independent package is filled and finally be sealed into to dry this coiled material and form pipe afterwards.
Example
The chemical modification lecithin that uses in these examples is from American lecithin Company
Aquasperse A.This product is hydroxylated lecithin, and it has water dispersibility characteristics.After chemical modification, this lecithin keeps oil molten, but also becomes water dispersible and can form emulsion oil-in-water.The lecithin of modification mixes with aqueous hydrogen peroxide solution or deionized water by mixer or by rocking in the container with very tight lid, in order to obtain stable emulsion.So the lecithin mixture of dilution is dispersed in the superoxol easily.The optical detection of moisturing capacity that contains the sterilising medium of lecithin is called by comprising in this sterilising medium
Fluorescer and the UV of coating surface take a picture to carry out.
According to table 1, modified lecithin and/or the non-ionic emulsifier polyethylene glycol 20 sorbitan monolaurate (Tween of multiple different amounts
TM20) mix with the aqueous hydrogen peroxide solution of 35wt%.The concentration of Tinopal is 2wt% in whole examples.The UV photo of Fig. 5 a to 5j is with same order correspondence example separately in the table.First three example is the benchmark example, does not comprise any dispersing agent fully or only comprises Tween20.
| Lecithin wt% | Tween20 wt％ | Tinopal wt％ | Wetting | Consumption | |
| Benchmark example 1 | --- | --- | 2 | --- | |
| Benchmark example 2 | --- | 0.3 | 2 | --- | |
| Benchmark example 3 | --- | 0.1 | 2 | --- | |
| Example 1 | 0.1 | --- | 2 | Good | Low |
| Example 2 | 0.1 | 0.1 | 2 | Good | Good (minimum level) |
| Example 3 | 0.3 | 0.1 | 2 | Good | Good |
| Example 4 | 0.3 | 0.2 | 2 | Good | Good |
| Example 5 | 0.1 | 0.3 | 2 | Good (minimum level) | Good |
| Example 6 | 0.3 | 0.3 | 2 | Good (minimum level) | Good |
| Example 7 | 0.4 | 0.3 | 2 | Oil is well still arranged a little | Good |
Example 1-7 illustrates when independent use modified lecithin and with various variable concentrations and Tween
TMDuring 20 compound, can obtain acceptable wetting, but can obtain in according to the situation of example 2-4 about the best attributes of consumption (being the absorption of superoxol)." consumption " meaning is to be carried and by this rubber cylinder and the amount that enters the disinfectant of heating chamber by this coiled material.If consumption is too low, final, Disinfection Effect is insufficient and unreliable.
Studied the impact of sterilising medium on surplus on the disinfecting surface, the result is illustrated among Fig. 6 a-6c.Used known
The ferric rhodanate method.According to this method, immerse with the ampoule of reagent (being ferric ion and ammonium thiocyanate acid solution) and to be filled with in the package of deionized water.If the residual peroxide of any trace is in the package of filling deionized water, it will become oxidation of divalent iron ion the ferric iron attitude and form red thiocyanate complex so.According to concentration, redness will have the different depths.In order to pass through approval, surplus should be less than 0.4ppm.
In these figure, unit is that the surplus of ppm is illustrated by Y-axis, and the time after the beginning illustrates in X-axis.After between one section of wrapping machine (use according to top Fig. 2 decontamination system) beginning, carry out the measurement of surplus at a plurality of diverse locations of package, namely after beginning 1,30,60,90,102 and 105 seconds, and 1,2 (3 package) after the beginning, 3,6,9,12,15,18,20 (2+5 packages), 23,26 and 29 minutes.Can find out that the value stabilization of surplus is in lower level along with machine gets warm and this technique arrive stabilized conditions.Operation test under three different conditions, namely about Fig. 6 a, adopt the operated by rotary motion of machine and use chemical modification lecithin (hydroxylated lecithin) as wetting agent, in Fig. 6 b, after heating chamber, do not produce such as extra air stream and the device of heat in order to reduce surplus, and at the bubble roller of heating chamber internal action on this coiled material, but utilize lecithin as wetting agent.About Fig. 6 c, this machine operates in the setting same with Fig. 6 b, but utilizes Tween
TM20 as unique wetting agent rather than this hydroxylated lecithin.The concentration of hydrogen peroxide in these three tests is identical in general, and therefore can not affect the output of these tests.Can find out that from Fig. 6 c by at the device that does not use any minimizing sterilised liq remnants, and this sterilised liq only has the Tween that adds this aqueous hydrogen peroxide solution to
TMCarry out this sterilization in 20 the situation, the hydrogen peroxide surplus is in unacceptable level.By making device above-mentioned, surplus will be reduced to below the 0.4ppm, use hydroxylated lecithin as the degree in the situation of wetting agent but also be less than.In Fig. 6 a and 6b, in this decontamination system, to use and do not use these extra devices, surplus is all very low, and is certainly, better in the first situation.
By using non-modified lecithin to replace the hydroxylated lecithin repetition according to the example of Fig. 5 and 6, the i.e. Leciprime of Cargill
TM1400IP.Acquisition is about the same result of hydrogen peroxide surplus in wetting, absorption and/or the package.This is possible according to principle of work, because when mixing with hydrogen peroxide, and the non-modified lecithin chemical modification that becomes.In the sterilising medium that obtains, no matter be to mix with chemical modification lecithin or general unmodified lecithin, total all will finally obtain same component and composition.When the non-modified lecithin of same use, this effect that obtains is unexpected and surprising.This effect is also extremely beneficial, because general, non-modified lecithin more cheaply and find in market easilier.
