Next the present invention mainly proves in terms of three:
Embodiment 7 sanitary considerations
Really wax bulk composition natural fat hydrochlorate demonstration: natural acid such as lac (light eleostearic acid class), Colophonium (abietic acid class),
Palmic acid (palmitic acid) etc. and ammonia (NH3-H2O), morpholineChemical combination.Chemically principle is inferred, main
To be following four big reaction species.
1, fatty acid ammonium salt: R-COOH+NH3·H2O→R-COO·NH4+H2O
Reaction condition: relatively low >=30 DEG C of i.e. solubilized reactions, activity is maximum.
Performance effect: water solublity is good, very effective can improve machine spray effect on fruit wax storage stability and fruit wax.Other
Without very positive interaction, it is auxiliary element in fruit wax.
Environmentally-friendly sanitary: be easier to decompose, is reduced into organic acid and volatilization ammonia, poisons the least, discuss slightly.
2, morpholine fatty acid salt (hydrogen bond salt):
Reaction condition: moderate, after fatty acid dissolves, 60～80 DEG C can be reacted, and activity is bigger.
Performance effect: good water solubility, stable.Fruit wax glued membrane levelability, adhesive force, brightness, vivid can be effectively improved
Property etc. a series of effects, and because glued membrane water suction is moderate, i.e. a large amount of water suctions are readily soluble is difficult to whiting, also can be extensive after a small amount of water suction whiting
Multiple, therefore can have preferable fresh-keeping effect as the main component of fruit wax, be early than the seventies in last century by the U.S.
402 succeed in developing the main body fruit wax composition being developed so far.
Environmentally-friendly sanitary: can decompose.Morpholine and corresponding fatty acid is resolved into after entering human body.U.S. testing result rat
LD50 of passing through mouth is 1600mg/kg, and within 1977, morpholine fatty acid salt is classified as GRAS material by U.S. FDA.
3, morpholine fatty acid ester salt:
(this ester salt is one of subject matter, and ester salt is the fruit wax bulk composition of the present invention)
Reaction condition: slightly higher.Preferably fatty acid is in 80～90 DEG C after alcohol water fully dissolves, and a few hours react, and activity is moderate.
Performance effect: good water solubility, stable.Waxing effect equally can be effectively improved fruit wax levelability, attached with hydrogen bond salt
Put forth effort, brightness, a series of effects such as vibrancy, and because ester bond salt is difficult to cracking because of steady chemical structure, therefore can inhale
Water and being difficult to returns white, protects light fresh-keeping effect time ester salt and certainly will be better than hydrogen bond salt.
Environmentally-friendly sanitary: be difficult to cracking.Enter human body the most substantially to discharge with esters state, though cracking, also ratio hydrogen bond salt
Produced morpholine much less.Clearly, morpholine belongs to a kind of harmful organic amine, though U.S. FDA is through rat entrance
It is classified as GRAS material after test, is indicated the boundary that can not be immediately poisoned.If nevertheless, when human body is few or time long
Trace takes in morpholine organic amine, and its harmful consequences is uncertain.In brief, human body had better not take in such material,
The fewest more non-hazardous.
4, morpholine fatty acid amide:
Reaction condition: higher, it is necessary in high temperature dehydration state response.Activity is little.
Performance effect: poorly water-soluble, nontransparent stable.Upper machine sprayability, quick-drying are better than ester salt and hydrogen bond salt, but attached
Put forth effort, brightness, other aspects such as freshness all not as good as ester salt and hydrogen bond salt, being particularly susceptible water suction whiting difficulty and recovering the most de-
Glue, cannot function as fruit wax bulk composition at all.There is not yet this type of report both at home and abroad, but the author it is reported, some Guo La manufacturer domestic
Because considering that dissolving hard fat acid (lac class etc.) needs, and heats up (how at 110～130 DEG C) with dissolved fat to water body pressure
Acid is reacted with morpholine and is converted wax, possible some do not know, at this point in the reaction, generate morpholine fatty acid amide probability significantly carry
, so that often there are the sequela such as whiting dewaxing in height on this market.
Environmentally-friendly sanitary: be difficult to cracking, toxicity is not surveyed, and enters human body and certainly easily drains not as good as ester salt and hydrogen bond salt, should not
Become fruit wax composition.
Morpholine fatty acid salt class (ester salt and hydrogen bond salt) contrast demonstration:
According to the acid number of natural acid, may infer that the compound molecular weight being combined with morpholine, thus judge that morpholine accounts for
The number of components of its compound, is contrasted by solid content weightless after solid content original after film forming and baking, and then infers because of cracking
The soap structure component of weightless composition.
Lac resin: acid number mostly is about 70, and single moles of carboxylic acids molecular weight is about 800, in conjunction with molecular weight after morpholine
Being 887, wherein morpholine occupancy volume is 9.81%.Rosin resin: acid number mostly is 100～130, and single moles of carboxylic acids molecular weight is 560
～430, in conjunction with molecular weight after morpholine 647～517, wherein morpholine occupancy volume is 13.44～16.82%.Palmic acid: acid number
218.8, single moles of carboxylic acids molecular weight 256, in conjunction with molecular weight 343 after morpholine, wherein morpholine occupancy volume is 25.36%.
The present invention specially utilizes lac and Colophonium respectively to do one group of contrast test, formula identical (especially fatty acid with
Quinoline ratio is consistent), main difference is reaction controlling condition.
After the hydrolysis of S-49: alcohol, 80～85 DEG C are reacted three hours；After the hydrolysis of S-50: alcohol, 75～80 DEG C are reacted one hour, pine
Fragrant；(formulation weight percentage ratio: abietic acid: morpholine: ammonia: ethanol: deionized water=18.0～19.0:3.0～3.2:2.8～
3.0:8.0～10.0:65.0～68.0)
After C-410:80 DEG C of hydrolysis, >=90 DEG C are reacted three hours；After C-425:65 DEG C of alcohol hydrolysis, >=90 DEG C of reactions three are little
Time, lac；(formulation weight percentage ratio: eleostearic acid: morpholine: ammonia: ethanol: deionized water=18.0～19.0:3.6～3.8:2.0
～2.5:8.0～10.0:65.0～68.0)
Test imagination, same reaction formula difference control condition, Colophonium group should be many with S-49 ester salt composition, and weightlessness should be less than
S-50；Lac should be many with C-425 ester salt composition, and weightlessness should be less than C-410.
Experimental Comparison result: original solid content (0) [100 DEG C of * 2hr], baking solid content (1) [130 DEG C of * 3hr], weight-loss ratio
After being baking, weight loss accounts for the percentage ratio of original solid content.Result of the test is determined for compliance with test imagination, S-50 and C-410 is weightless
Rate, obviously higher than S-49 and C-425, refers to table 1.
Meanwhile, the present invention has carried out tens groups times repeatedly test SW-68 and the U.S. 402 and many group waxy product of domestic fruit
Baking weight-loss ratio, refers to table 2.
Table 1
Table 2
Deduction, above-mentioned fruit wax main component can be inquired into.
SW-68A: natural acid morpholine ester salt, silicone-acrylic water-soluble resin；
SW-68B: silicone-acrylic water-soluble resin, light eleostearic acid morpholine ester salt；
SW-68C: silicone-acrylic water-soluble resin, (lysate is mainly NH3)；
U.S. 402: fatty acid morpholine hydrogen bond salt masterpiece, FDA author；
Beautiful 402D:402 improves thing, it is clear that ester salt composition improves, and hydrogen bond salt composition the most substantially lowers perhaps added with modification
Resin, is the imported product of China's current consumption maximum, and reaction is good；
State sample A: approximation 402D, ester salt hydrogen bond salt equilibrium, concentrated expression is normal, is increasingly becoming a domestic brand；
State sample B: it will be apparent that main body is palmitic acid morpholine hydrogen bond salt, with low cost, Market reaction still can, but because of easily water
Molten delustring, therefore the effect such as fresh-keeping is not as good as domestic sample A；
State sample C: fatty acid morpholino amide is many, therefore muddiness is the most durable, and the whiting that easily absorbs water, future trouble is not surveyed, and is that high temperature is high
Suppress standby, in currently improving；
State sample D: similar domestic sample C, there is a morpholino amide composition, but fewer than C (translucent and store this point of long susceptible of proof), it is coated with
The most hygroscopic whiting of fruit.
Integration test result is seen, SW-68 high temperature weight-loss ratio is all significantly lower than 402D (being more more than 402), then the most permissible
Inferring, SW-68 mono-aspect had both met current FDA standard, and on the other hand it is not surveyed hazardness and is less than 402D yet.From the perspective of from this point,
Whether relevant hygiene department should revised sanitary standard: improves ester salt composition, reduces hydrogen bond salt composition, stops amide
Part.For another point says the most permanently effective science health angle point, really the direction of wax development should be SW-68C series products,
Organic amine without morpholine, even if stable is difficult to cracking fission and the polymer waterborne thing mistake without other bad sequela
Food is also easily normally mediated.
It is presently believed that development fruit wax based food contact series products even other direct foodstuff products, must abundant profit
Inquire into by chemistry base reason and speculate and then resolution, the most just meet the scientific development of human survival.
Machine effect in embodiment 8
Any industrial products, if supreme machine operability, even if environmentally-friendly sanitary, performance are the best again, all are futile effort.Really
Wax is operated the computer to be become China and waxes now the actual state of industry, therefore upper machine controllability must be paid attention to, and the present invention is according to existing
The result of field experimental observation, is summarized as follows.
1, upper machine spraying (predominantly fruit wax sprayability): SW-68A, SW-68B are bordering on 402D, and current machine performance can be grasped
Make；SW-68C atomization shortcoming (Polymer Systems, though water-soluble good, viscosity is slightly higher)；
2, aridity (predominantly quick-drying and non-stick): SW-68A, SW-68B, SW-68C are significantly better than that 402D；
3, brightness (predominantly showing aesthetic property): due to the factor containing natural acid, so SW-68A, SW-68B
Being coated with fruit the most same vibrancy 402D, though SW-68C bright property is good, but vivid degree is not as good as SW-68A, SW-68B, 402D；
4, smoothness (performance handling property): SW-68 is superior to 402D, the viscous packaging of tack-free viscous bag；
5, store long property: current Tu Guo enterprise mostly is open place, and go out the fruit phase and mostly be early autumn to the early spring, different places or areas,
Affecting the heaviest phase is the severe winter, and really wax i.e. has thick change in case of cold or be weak to freezing, necessarily affects painting fruit efficiency and performance, so item is wanted
Ask and must give attention.SW-68 and 402 all stores the most resistance to freezing, even if at subzero 10 degree～during 20 degree of fully charges, defrosting can be the most extensive
Restore state.
In terms of sprayability, ester salt is micro-is inferior to hydrogen bond salt (hydrogen bond water-soluble is slightly higher than ester salt)；In light freshness and storage
Property aspect for a long time, the two is consistent；In terms of aridity with smoothness, ester salt is substantially better than hydrogen bond salt.Here it is both upper machine effects
Comparison.
Embodiment 9 fresh keeping property
Really film function: one is appearance looks elegant；Two is the most fresh-keeping.In terms of primary efficacy, should be the latter, but the two is in fact
Consistent.Inventor arrives through experimental observation over the years, if being often coated with wax fruit outward appearance have mutation water suction, delustring or coloured different,
Finally the most easily go mouldy rotten.
Fruit is anhydrous i.e. has no result, and water, for fruit growth and storage, has a basic biotic factor, but water pair exactly
The destructive degree also maximum of fruit is the easiest.For Fructus Citri tangerinae orange Citrus chachiensis Hort., process the most in time after once soaking water, then the most i.e. can be mould
Rotten.Naturally preserve observation from fruit, also can every day weightless (the most namely dehydration), weightlessness to a certain extent that is is gone rotten, institute
With, the most fresh-keeping key element of fruit waxing safeguards water balance in sporocarp exactly, extends equilibration time, reduces weight-loss ratio, its
Key element controls chemical equilibrium the most exactly.For in this way: really wax fruit wax, should can water-soluble be first to become water-based system,
Even if can excrete after being fully hydrolyzed next to that eat by mistake, these are environmentally-friendly sanitary requirements；Also want to control Wax with water contained film
After the most hygroscopic, meet cold and hot change be difficult to cracking change, these are fresh-keeping requirements.How to study well the performance chemical balance of water,
Here it is that develops fruit wax at all will be.
For fatty acid, potassium, sodium salt should be not only stable water soluble but also preferably, but owing to potassium, sodium salt water suction are the most general
In vain, dying upper selects with this without producer, and amide is water-soluble good is difficult to the most again whiting, so numerous manufacturer the most all selects its adapted.?
Quinoline is the most water-soluble to be had not only corresponding adhesive force simultaneously but also is difficult to whiten relatively stable, therefore the U.S. has started this type of fruit wax and continued into the present.But
The present from that discussed above in for known chemically structure, ester salt is than hydrogen bond salt is stable and water solublity is the best, after becoming cere, ester salt
Hydrogen bond salt all it is better than in water-fast anti-whiting, brightness, fresh-keeping persistent period.
The author in recent years from China fruit the field observation of wax market and repeatedly contrast sampling test learn, water-fast on current market
Fresh-keeping effect, is really best with U.S. 402D.
Table 3 (really wax is coated with Fructus Citri tangerinae submerging test):
Chemical analysis structural agent is discussed: 68A combination natural acid morpholine ester salt and organosilicon acrylic resin；68B combines light paulownia
Acid morpholine ester salt and organosilicon acrylic resin；The pure organosilicon acrylic resin of 68C.The little activity of abietate's molecules of salt amount the most easily splits mutability, light eleostearic acid greatly
Ester salt is the most stable, and silicon third is the most stable without mutation.Immersion failure test exactly adds clear this point.
Table 4 (really wax immersion go mouldy weightless contrast) A (SW-68A) D (402D)
Table 5 (natural storage weightlessness contrast after really wax is coated with fruit)
Illustrate: it is similar with 402D that the present invention has SW-68A structural constituent only, therefore the contrast taken.Result shows, broken in immersion
Bad property test aspect, both contrasts are relatively big, and SW-68A is substantially better than 402D, and in terms of natural storage, both are very nearly the same, but still
So SW-68A to be better than 402D slightly.
Immersion 4 minutes SW-68A, 402D homogeneous weeks of failure test are out of control, but contrast test SW-68B of the present invention is soaked 5 points
Within one or two weeks, also normally SW-68C immersion is more as good as more than 15 minutes January clock.Known have chemical analysis master control to be become, the most
State.
Embodiment 10 comprehensively illustrates
The ultimate constituent of novel fruits preservative fruit wax SW-68A, SW-68B, SW-68C of the present invention (includes other by-products
Or leave over composition) refer to lower list 6 (percentage ratio).
Table 6
Novel fruits preservative fruit wax SW-68A, SW-68B and SW-68C of the present invention are full water-soluble system；SW-68A、
SW-68B outward appearance is purplish red as clear as crystal, and SW-68C outward appearance pure water color is colourless as clear as crystal；Its master control water-soluble components is fat
Barbiturates and middle polyphosphazene polymer ester ammonium salt.
Complete water-soluble system wax liquid is all better than oil-in-water type or floating type wax liquid in stability, the carefully property tied, film property each side,
The most just due to combine salt water soluble natural sex, the environmentally-friendly sanitary that is also highly advantageous to control particularly become cere eat by mistake after also
Can normally excrete, so these main points are i.e. the primary starting points of the present invention.
Design synthesis, with fatty acid morpholine ester salt for main body fruit wax composition, is possible not only to substantially reduce morpholine lysate to subtract
Harm human factor improves hygiene and health effect less, and its water solublity is similar with morpholine fatty acid hydrogen bond salt.Its comprehensive preservation
Effect is also better than hydrogen bond salt, and this is one of the main points of the present invention.
Design synthesis be polymerized with the aqueous solution of organosilicon-modified acrylic in macromolecule resin for fruit wax auxiliary ingredients or
Main component, reduce or the most Chu fatty acid morpholine salt composition.The environmental protection that such technical products should become the mankind controlled is defended
Raw and cheap and good-quality novel fruit wax (or other similar hygienic article) developing direction.This is the two of main points of the present invention.
Although pure acrylic acid is water-soluble good stable again, but is extremely short of at aspects such as adhesive force, water-resistance, cold-and-heat resistents, draw
Enter active organosilicon copolymerized therewith, this respect can be overcome completely to be short of, can extremely efficient reach the most molten water but also control water
Advantage.
By-product (unreacting propylene acid esters, potassium sulfate): one of future trouble factor of high molecular polymerization, it is necessary to control.This
Bright utilize special process (particularly adding initiator, such as potassium peroxydisulfate) to be reduced or eliminated, current unreacted monomer trace, add
Upper toxicity own is the least, more go up film and almost volatilizees nothing left, so nothing very hidden danger.For potassium peroxydisulfate consumption in this this formula relatively
Many, its effect one is to cause macromolecule, and two is to close macromolecule, and residue person becomes K in body series2SO4Potassium sulfate, for people
Class edibility salt, harmless.
Auxiliary ingredients: fatty acid ammonium salt, auxiliary body, improves water-soluble；Ammonium hydroxide regulation finished product PH；Ethanol, isopropanol are
Controllability food grade solvent.This kind solvent contributes to fat acid dissolution reaction and high molecular weight reactive in a word, is also highly advantageous to and is being coated with
Fruit plays table bactericidal action at the beginning, i.e. volatilizees after achievement wax；Deionized water is the pure water specially processed, and is the main body of water-borne wax liquid
Solvent.
