Embodiment 7 sanitary considerations
Really wax bulk composition natural fat hydrochlorate demonstration: natural acid such as lac (light eleostearic acid class), Colophonium (fir
Acids), Palmic acid (palmitic acid) etc. and ammonia (NH3-H2O), morpholineChemistry knot
Compound.Chemically principle is inferred, 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, are 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, light can be effectively improved
Degree, a series of effects such as vibrancy, and because glued membrane water suction is moderate, i.e. a large amount of water suctions are readily soluble is difficult to whiting, few
Also can recover after amount water suction whiting, therefore can have preferable fresh-keeping effect as the main component of fruit wax, be
Succeeded in developing the main body fruit wax composition being developed so far by the U.S. 402 early than the seventies in last century.
Environmentally-friendly sanitary: can decompose.Morpholine and corresponding fatty acid is resolved into after entering human body.U.S.'s detection knot
Really rat oral LD50 is 1600mg/kg, and within 1977, morpholine fatty acid salt is classified as GRAS by U.S. FDA
Material.
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,
Activity is moderate.
Performance effect: good water solubility, stable.Waxing effect equally can be effectively improved fruit wax levelling with hydrogen bond salt
Property, adhesive force, brightness, a series of effects such as vibrancy, and because ester bond salt because of steady chemical structure not
Easily cracking, therefore can absorb water and be difficult to return white, protect 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 can discharge with esters state, even if crack, also than
Morpholine much less produced by hydrogen bond salt.Clearly, morpholine belongs to a kind of harmful organic amine, the U.S.
Though FDA is classified as GRAS material after rat entrance is tested, indicate the boundary that can not be immediately poisoned.But
In any case, if trace takes in morpholine organic amine when human body is few or time long, 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 at adhesive force, brightness, other aspects such as freshness all not as good as ester salt and hydrogen bond salt, it is particularly susceptible water suction general
White difficulty recovers even degumming, cannot function as fruit wax bulk composition at all.There is not yet this type of both at home and abroad to report, but pen
Person it is reported, some Guo La manufacturer domestic is because considering that dissolving hard fat acid (lac class etc.) needs, to water body
Pressure heat up (how at 110～130 DEG C) react with morpholine again with dissolved fat acid and convert wax, possible some do not know,
At this point in the reaction, the probability generating morpholine fatty acid amide is greatly improved, so that often occurring general on this market
The sequela such as butter wax.
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
Quinoline accounts for the number of components of its compound, is contrasted by solid content weightless after solid content original after film forming and baking, enters
And infer because of the soap structure component of the weightless composition of cracking.
Lac resin: acid number mostly is about 70, and single moles of carboxylic acids molecular weight is about 800, in conjunction with morpholine
Rear molecular weight is 887, and wherein morpholine occupancy volume is 9.81%.Rosin resin: acid number mostly is 100～130, list
Moles of carboxylic acids molecular weight is 560～430, and 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 molecule after morpholine
Amount 343, wherein morpholine occupancy volume is 25.36%.
The present invention specially utilizes lac and Colophonium respectively to do one group of contrast test, identical (the especially fatty acid of formula
Consistent with morpholine ratio), 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 of reactions
One hour, Colophonium；(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 anti-
Answer three hours, 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, lose
Heavily 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 * 3
Hr], after weight-loss ratio is 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 weight-loss ratio, obviously higher than S-49 and C-425, refers to table 1.
Meanwhile, to SW-68 and the U.S. 402 and how the group waxy product of domestic fruit have carried out tens groups times instead to the present invention
Repetition measurement tests 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 and perhaps adds
Having modified resin, be the imported product of China's current consumption maximum, reaction is good；
State sample A: approximation 402D, ester salt hydrogen bond salt equilibrium, concentrated expression is normal, is increasingly becoming domestic product
Board；
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 the most water-soluble 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 do not surveys,
It is prepared by High Temperature High Pressure, in currently improving；
State sample D: similar domestic sample C, there is a morpholino amide composition, but fewer than C (translucent and storage can be demonstrate,proved for a long time
This point real), 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
Last it is inferred that SW-68 mono-aspect had both met current FDA standard, on the other hand it is not surveyed hazardness and wants yet
Less than 402D.Froming the perspective of from this point, whether relevant hygiene department should revised sanitary standard: improve ester salt one-tenth
Part, reduce hydrogen bond salt composition, stop amide composition.The most permanently effective science health angle is said from another point
For Dian, really the direction of wax development should be SW-68C series products, and without morpholine organic amine, stable being difficult to is split
Even if solving fission and the polymer waterborne thing without other bad sequela being eaten by mistake and also easily normally mediated.
It is presently believed that development fruit wax based food contact series products even other direct foodstuff products, must fill
Divide and utilize chemistry base reason to inquire into supposition 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.Really wax is operated the computer becomes China and waxes now the actual state of industry, therefore upper machine controllability must weigh
Depending on, the present invention, according to the result of on-the-spot experimental observation, is summarized as follows.
1, upper machine spraying (predominantly fruit wax sprayability): SW-68A, SW-68B are bordering on 402D, now machinery
State is operable；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 the most excellent
In 402D；
3, brightness (predominantly showing aesthetic property): due to the factor containing natural acid, so SW-68A,
SW-68B be coated with fruit the most same vibrancy 402D, though SW-68C bright property is good, but vivid degree 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, sky
North, ground, south, affect 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 and imitates
Rate and performance, so item requires to give attention.SW-68 and 402 all stores the most resistance to freezing, though subzero 10 degree～
During 20 degree of fully charges, defrosting can recover rapidly ortho states.
In terms of sprayability, ester salt is micro-is inferior to hydrogen bond salt (hydrogen bond water-soluble is slightly higher than ester salt)；Bright and new
Spending and store long property aspect, the two is consistent；In terms of aridity with smoothness, ester salt is substantially better than hydrogen bond salt.This
It it is exactly the comparison of both upper machine effects.
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 its
It is consistent both real.Inventor arrives through experimental observation over the years, has mutation to inhale if being often coated with wax fruit outward appearance
Water, delustring or coloured different, 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 exactly
It is that water is the easiest to the destructive degree also maximum of fruit.For Fructus Citri tangerinae orange Citrus chachiensis Hort., process the most in time after once soaking water,
The most i.e. can go 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, so, the most fresh-keeping key element of fruit waxing safeguards water in sporocarp exactly
Balance-dividing, extends equilibration time, reduces weight-loss ratio, and 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 next to that eating by mistake after being fully hydrolyzed
Can excrete, these are environmentally-friendly sanitary requirements；Also want can control Wax with water contained film after the most hygroscopic, meet cold and hot
Change is difficult to cracking change, and these are fresh-keeping requirements.How to study well the performance chemical balance of water, here it is grind
System fruit wax at all will be.
For fatty acid, potassium, sodium salt should be not only stable water soluble but also preferably, but due to potassium, sodium salt water suction
I.e. easily whiting, dying upper selects with this without producer, and water-soluble good being difficult to the most again of amide is whitened, so numerous manufacturer is also
All select its adapted.Morpholine 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. opens
Create this type of fruit wax to continue into the present.But the present from that discussed above in for known chemically structure, ester salt hydrogen bond to be compared
Salt is stable and water solublity is the best, and after becoming cere, ester salt is equal in water-fast anti-whiting, brightness, fresh-keeping persistent period
It is better than hydrogen bond salt.
The author in recent years from China fruit the field observation of wax market and repeatedly contrast sampling test learn, on current market
Water-fast 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 group
Close light eleostearic 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 is the most relative
Easily splitting mutability, light eleostearate is the most stable, and silicon third is the most stable without mutation.Immersion failure test is exactly added
Understand 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,
In terms of immersion destructive testing, both contrasts are relatively big, and SW-68A is substantially better than 402D, in natural storage side
Face, both are very nearly the same, but still 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
Soak 5 minutes one or two weeks also normal, SW-68C immersion is more as good as more than 15 minutes January.Known have chemistry one-tenth
Much more no longer part master control is become, to 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 it
His by-product 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 fatty acid salt and middle polyphosphazene polymer ester ammonium salt.
Complete water-soluble system wax liquid is all better than oil-in-water type or floating type in stability, the carefully property tied, film property each side
Wax liquid, the most just owing to combining the water soluble natural sex of salt, the environmentally-friendly sanitary that is also highly advantageous to controls particularly
Cere is become also to be able to normally excrete, so these main points are i.e. the primary starting points of the present invention after eating by mistake.
Design synthesis, with fatty acid morpholine ester salt for main body fruit wax composition, is possible not only to substantially reduce morpholine cracking
Thing improves hygiene and health effect to reduce harm human factor, and its water solublity is with morpholine fatty acid hydrogen bond salt phase
Imitative.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 assists into macromolecule resin in the aqueous solution polymerization of organosilicon-modified acrylic for fruit wax
Part or main component, reduce or the most Chu fatty acid morpholine salt composition.Such technical products should become the mankind
Controlled environmentally-friendly sanitary 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 the most deficient at aspects such as adhesive force, water-resistance, cold-and-heat resistents
Lack, introduce active organosilicon copolymerized therewith, this respect can be overcome completely to be short of, can extremely efficient reach
The most molten water but also the advantage controlling water.
By-product (unreacting propylene acid esters, potassium sulfate): one of future trouble factor of high molecular polymerization, it is necessary to control
System.The present invention utilizes special process (particularly adding initiator, such as potassium peroxydisulfate) to be reduced or eliminated, and shows
Time unreacted monomer trace, add that toxicity own is the least, more go up film and almost volatilize nothing left, so without the most hidden
Suffer from.More for potassium peroxydisulfate consumption in this this formula, its effect one is to cause macromolecule, and two is to close macromolecule,
Residue person becomes K in body series2SO4Potassium sulfate, for mankind's edible salts class, harmless.
Auxiliary ingredients: fatty acid ammonium salt, auxiliary body, improves water-soluble；Ammonium hydroxide regulation finished product PH；Ethanol,
Isopropanol is controllability food grade solvent.This kind solvent contributes to fat acid dissolution reaction and macromolecule is anti-in a word
Should, also it is highly advantageous to and plays table bactericidal action at the beginning painting fruit, i.e. volatilize after achievement wax；Deionized water is for specially to locate
The pure water of reason, is the bulk solvent of water-borne wax liquid.
