The said product is compounded with antifermenting agent DMF, antioxidants and synergist and through the steps of heating, mixing and mixing with carrier. Of its components, DMF is one kind of high efficiency antifermenting agent with "sublimation" feature; antioxidants BHA and BHT can be dissolved in EMQ and have "creep flow" effect; and the synergist including mainly phosphoric acid and citric acid has obvious synergistic effect to both antifermentation and antioxidation. The present invention is one kind of ideal compound feed antifermenting and antioxidizing agent.
Description
The present invention relates to a kind of compound feed antifermenting and antioxidizing agent and production method thereof.
Because the various raw materials of its composition contain moisture content and various nutrition, add suitable air themperature and humidity in the various mixed feeds of suitability for industrialized production, some moulds very easily breed, and cause going mouldy of feed.Owing to go mouldy and with the naked eye easily observe usually, light then conversion ratio that reduce the tiring of feed, feed descends, and is heavy then produce toxin, growth of animals or poultry stagnate or internal organs such as slow, liver kidney impaired, interference immuning system, reduction fertility, even cause livestock and poultry death.For this reason, worked out in the method for inspection, GB13092-91 feed of salmonella in the GB13091-91 feed in the mould method of inspection, the GB19093-91 feed aflatoxins B in the assay method of total number of bacteria, the GB8381-87 feed in the present feed test standard
1Standards such as assay method.The method of mildew-resistant has: reduces the moisture content in the feed, the storage temperature of reduction feed, reduces ways such as air humidity and interpolation mould inhibitor, since objectively all, effectively the simplest with the interpolation mould inhibitor.At this, the harm of going mouldy, poison become and the mechanism of mould inhibitor repeats no more, and emphasis has a talk the Midew preventive for feed kind commonly used and the operating position of these kinds.The kind of Midew preventive for feed has a lot, and commonly used is organic acid and their salt thereof, and for example: formic acid, acetate, propionic acid, benzoic acid, sorbic acid and their sodium thereof, potassium, ammonium salt also have dehydroacetic acid, parabens, dimethyl fumarate or the like.Many manufacturers also adopt above-mentioned kind the processing of certain technology and carrier to be mixed with different kinds, and for example commodity are by name: mould inhibitor MI-2500, the gram that mould enemy, Wan Lubao, road protect thin, Yi Erjing, remove mould clean, Methylpartricin Sodium Laurylsulfate, mould natural enemy and Ministry of Agriculture's approval registration import in 96 years is mould, the mould 1330-second of speed gram, the mould 1498-E of speed gram, the mould 1608-E of speed gram ...Below, introduce several principal item operating positions earlier.1. propionic acid and propionate
Propionic acid and propionate are use amount maximums up to now, with the longest history, the most widely used Midew preventive for feed kind.Propionic acid is to have a pungent colourless liquid of similar acetic acid, can with immiscible organic solvents such as water, alcohol, ether, chloroform, propionic acid contains energy, metabolizable energy is 4946 kcal/kg.Usually propionic acid is subjected to hydrogen bond action and exists with dimer, as changes into monomer and can strengthen antimold activity, as makes suspension, makes it to be easy to disperse, and bacteriostatic activity is more excellent.
Calcium propionate is white crystalline powder, and is water-soluble, is insoluble to alcohol.Sodium propionate is colourless crystallization or white powder, and is soluble in water, is slightly soluble in alcohol.Propionate suits to use (requiring pH value less than 5.0) under acid condition.
In addition,, and lasting antimold activity is arranged, propionic acid is made ammonium salts (for example dipropionic acid ammonium) for peculiar smell and the corrosivity that overcomes propionic acid, more preferably.Propionic acid and propionate toxicity are low, can relievedly use.2. sodium Diacetate
This product is the compound that acetate and sodium acetate combine with special shape, and product is a white crystalline powder, has strong acetate smell, and is soluble in water, pure equal solvent.The domestic existing many units of these product go into operation, anti-mold effect basically with propionic acid and propionate compound like or slightly poorer.Sodium Diacetate uses extremely safe.In addition, this product is used for milk cow forage and can improves milk production and butterfat percnetage.3. sorbic acid and its esters
Sorbic acid is a white, needle-shaped crystals, is dissolved in multiple organic solvents such as alcohol, ether, is slightly soluble in hot water.Potassium sorbate is colourless or white phosphorus flaky crystal or crystalline powder, and is soluble in water.This product is safe in utilization, and is effective, but the price height, less independent use in the feed in the native land.4. Sodium Benzoate
This product is white particle or crystalline powder, and is soluble in water, is slightly soluble in alcohol, and the aqueous solution shows slightly alkalescence.Product must have mildew-proof function under acid condition, PH is 5.5 when above, the anti-mold effect extreme difference.Safety in utilization is slightly poor.5. dimethyl fumarate
The English DMF that is called for short of this product, outward appearance is white crystals or powder, is dissolved in ester class, chloroform and isopropyl alcohol equal solvent, is slightly soluble in water, DMF can distil.Product characteristics is a has a broad antifungal spectrum, and mildew-proof function is strong, and the variation of pH value and the relation of mildew-proof function are little, and the more unquenchable Aspergillus flavus of other mould inhibitor is had stronger inhibitory action.Though DMF belongs to low toxicity material (big white mouse LD
50Be 2240mg/kg), but disputable to the safety in utilization of DMF up to now.6. mildew inhibitor for feed
Can also have many kinds by the mould inhibitor that uses of approval in feed, from present trend and opinion, it is effective that compound mould inhibitor kind demonstrates, many-sided advantages such as safe in utilization, reasonable price.At present the commercially available kind good and the bad differs, and has plenty of that dragons and fishes jumbled together, mixes the genuine with the fictitious, and needs the user correctly differentiate use.
Have a talk again feed oxidation and use the importance of antioxidant.Feedstuff-meat ratio is one of key issue of plant's attention, also is the key index of weighing the feed quality.For example: the feedstuff-meat ratio of fryer is usually at (2.0-2.4): 1; The feedstuff-meat ratio of sucking pig is about 1: 1.What many raising workers considered often is the kind of poultry or livestock, the temperature in booth or place, ventilation, daylighting and stocking density, nutrition and energy in the feed, for example protein, fat, vitamin, trace element ... or the like.Many feed factories, the speed of especially selling is fast, feed is from producing short middle-size and small-size feed factory of sales cycle, very easily interpolations antioxidant has been neglected, and can accomplish that the component of key is not is not used inferior materials and turned out substandard goods good at last.Production of fodder factory always thinks that the feed of oneself producing is qualified, when dispatching from the factory and never degenerate or rotten as yet, and is the keeper unmanned basically or few people detect whether oxidation of fat in the feed? the vitamin A, the D that also contain what units in every gram feed
3, carrotene ..., What is more, serious rance feed mixed the back sell with fresh feed, has a strong impact on raising worker's interests.And some ignorant idea is the feed of poultry and livestock is not people's dish of having a meal, and more of poor quality it doesn't matter ...
In a word, go mouldy and the loss that causes of oxidation much larger than the cost that adds mildew-resistant antioxidant, go mouldy and the speed of oxidation is undertaken by geometric progression.Know that adding mildew-resistant antioxidant will not add before various components are rotten as yet, can play a multiplier effect, otherwise just of no avail.The factory of many mixed feeds reduces raw material variety in order to simplify production technology, is willing to use composite mildewproof antioxidant (use multidimensional and premix concentrate feed are as a same reason with being willing to).
The purpose of this invention is to provide a kind of cost low, have no side effect, the significant compound feed antifermenting and antioxidizing agent of mildew-resistant antioxidant effect.Mould inhibitor DMF and antioxidant EMQ, BHA etc. share, and can play obvious role in synergism, and under the effect of the synergist that other adds, its mildew-resistant antioxidant effect is stronger.Its mechanism is to utilize the main body of " distillation " mechanism of DMF as mould inhibitor, and when playing mildew-proof function, DMF is antioxidant effect slightly.For fear of the toxic and side effect of DMF, the concentration of DMF in feed is suitable to be controlled at below the 400PPm, and common concentration is controlled between the 200-300PPm, according to experiment, uses at this low concentration, also slightly promotes the growth effect.Because EMQ and BHA also have stronger mildew-proof function, share with DMF and strengthened anti-mold effect greatly.EMQ, BHA and BHT system mixes and uses antioxidant effect obvious based on the component of antioxygen, and BHA and BHT all can be dissolved among the EMQ, is added on to have good " stream (Creeing) feature of wriggling in the feed.Even composite mildewproof antioxidant uses the back that the inhomogeneous part of stirring is arranged in feed, because " distillation " and " stream of wriggling " effect is stronger, the mildew-resistant antioxidant effect that is risen is also stronger in depositing process for it.Synergist serves as main the composition with phosphoric acid and citric acid, and itself is acidic materials, has certain bactericidal effect, plays anti-mold effect.Synergist can complexation of metal ions, reduces the oxidation catalysis effect of metal ion, makes part antioxidant obtain regeneration simultaneously again after playing antioxidation and continues to play antioxidation, so increased the antioxidant effect of antioxidant significantly.
Particular content of the present invention is as follows: this composite mildewproof antioxidant is mainly formulated by mould inhibitor DMF, antioxidant (EMQ, BHT, BHA), synergist (phosphoric acid, citric acid etc.) and carrier, wherein: (1) mould inhibitor (meter by weight) DMF 100 (2) antioxidant (meter by weight) EMQ 100
BHA?0.5-5
BHT 10-80 (3) synergist (meter by weight)
Phosphoric acid (containing heavy more than 85%) 100
Citric acid 10-50
The proportioning (weight ratio) of disodium EDTA 0.5-10 (4) mould inhibitor, antioxidant and synergist is: mould inhibitor: antioxidant: synergist=1: (0.2-0.8): (0.1-0.4) production method of this composite mildewproof antioxidant is as follows: the preparation of (1) antioxidant
EMQ is heated to 60-90 ℃, BHA, BHT all are dissolved among the EMQ, it is standby to obtain oily liquids after stirring; (2) preparation of synergist
Disodium EDTA and citric acid directly can be added and be heated to 60-90 ℃ of dissolving in the phosphoric acid, can add low amounts of water for a long time as above-mentioned two material umbers and make its whole dissolvings, the back that stirs is standby; (3) carrier of selecting for use of carrier can be selected zeolite powder, diatomite, white carbon black etc. for use; Earlier carrier and DMF are stirred when (4) various materials are mixed, then in: mould inhibitor: antioxidant: synergist=1: (0.2-0.8): ratio (0.1-0.4) sprays into the antioxidant and the aqueous synergist of oily in the carrier, and stirring promptly gets product.Because various carrier absorption properties differ greatly, the total amount of the mould inhibitor in the adding carrier, antioxidant, synergist is advisable not beat the unity piece, and will keep good mobility, makes it to be distributed in the feed equably to go.
Advantage of the present invention and good effect are as follows:
1. anti-mold effect is remarkable.That this product mainly plays mildew-proof function is DMF, but because the synergistic function of EMQ, BHA and synergist, is that DMF is unrivaled when using separately.
2. antioxidation is obvious.That this product mainly plays antioxidation is EMQ, BHT and BHA, but synergist plays synergistic effect equally, and mould inhibitor DMF is antioxidant effect slightly also.
3.DMF distillation and be dissolved in BHA, BHT among the EMQ and have " distillation " and " stream of wriggling " effect respectively, in feed, use fully mixing, and along with the rising of storage temperature, " distillation " of composite mildewproof antioxidant and " stream of wriggling " phenomenon is strengthened along with the rising of temperature in feed, so mildew-resistant and antioxidation are along with the rising of temperature is also strengthened thereupon.
4. the effect of synergist has the following aspects:
(1) synergist is acidic materials, itself has the mildew-proof function of certain bactericidal;
(2) synergist can increase the antioxidant effect of antioxidant, and can make part antioxidant continue to obtain " regeneration " behind the performance antioxidant effect, continues to play the effect of antioxidant;
(3) metal ion in the complexing feed, inhibition or reduction metal ion are to the oxidation catalysis effect of nutritions such as vitamin in the feed and grease.
5. because the working concentration of DMF in feed obviously reduces,, guarantee the safe handling of DMF in feed so obviously reduce for the toxic and side effect that is mixed in the impurity among the DMF.
6. the compound feed antifermenting and antioxidizing agent production cost produced of the present invention is low, technology is simple, high efficiency, nothing " three wastes " pollute, economize, and product is easy to use by investment of production equipment.
Over past ten years, the inventor constantly studies the synthesis technique and the relevant toxicological test result of concern of DMF, and constantly develop the proportioning of composite mildewproof antioxidant, performance for more various products, once with composite mildewproof antioxidant and mould inhibitor DMF, sodium Diacetate, calcium propionate, potassium sorbate, Sodium Benzoate and antioxidant EMQ, BHT, etc. product in the feed of chicken and piggy, add the mould inhibitor and the antioxidant of same expense, its result all is best results of composite mildewproof antioxidant.Order arrangement by the anti-mold effect power is: composite mildewproof antioxidant DMF, EMQ, Sodium Benzoate, calcium propionate, sodium Diacetate, potassium sorbate, wherein therefore potassium sorbate adopts same expense owing to the too low anti-mold effect that does not have expection of concentration that uses owing to cost an arm and a leg; Antioxidant effect is that composite mildewproof antioxidant is suitable with EMQ, is much better than BHT.Table one, table two and table three are respectively the result in the intermittent drizzles in the rainy season test in season of area, Shanghai nineteen ninety and 1994, what adopt is the feed of chicken and piggy, and method is that the mildew-resistant antioxidant kind of adding the same price is with the naked eye observed it with outward appearance and gone mouldy and the order of severity of oxidation.(seeing table one, two, three for details)
