Abstract
The invention belongs to the technical field of feed additives, and particularly relates to a stearic acid mixture, and a preparation method and application thereof. The stearic acid mixture provided by the invention comprises the following components in percentage by weight: 10-35% of stearic acid, 10-30% of magnesium stearate, 30-50% of calcium stearate and 5-10% of silicon dioxide. The stearic acid mixture provided by the invention has favorable mixing uniformity in the feed, reduces the consumption of stearic acid, and especially can enhance the meat yield of lambs after being mixed with the lamb feed.
Description
Technical field
The invention belongs to field of feed additive technology, particularly to a kind of stearic acid mixture and preparation method thereof and should
With.
Background technology
In the Feed Manufacturing course of processing, some raw materials easy moisture absorption caking or viscosity be strong, poor fluidity, pulverized in processing
In journey, often caking cannot be processed, and therefore often adds wandering agent.
Wandering agent, also known as anti-caking agent, can improve feedstuff mobility, prevents from luming, and be conducive to improving it and rush down note property and storage
The function of the stability deposited, is conducive to the accuracy of dispensing and the mix homogeneously of feedstuff.
How as anti-caking agent, large usage quantity in feedstuff, addition is 1-10% to stearic acid.But stearic acid is in feedstuff work
In industry with when have a following defect: sterling stearic acid because its density is less, loose, there is certain viscosity and lead to free-running property relatively
Difference, the mixing homogeneity therefore in feedstuff is extremely limited, has had a strong impact on using effect in feedstuff for this product.For upper
State deficiency, Chinese patent cn104186972b discloses a kind of stearic acid mixture, and component includes stearic acid, silicon dioxide, chlorine
Change calcium.The technical problem underlying that this patent solves is under identical action effect, reduces stearic consumption.
Stearic acid is not only a kind of anti-caking agent, simultaneously a kind of still energy feedstuff, due to fatty acid is directly added into can be right
Animal tumor damages for gastric microorganism, and and then affect cud in microorganism normal fermentation, be unfavorable for the health of animal.
Therefore poor except there is free-running property, we also should need to consider that stearic acid is used for how playing good nutriture value in feedstuff
Value.
Content of the invention
It is an object of the invention to provide a kind of stearic acid mixture and its preparation method and application, described stearic acid mixing
Thing has good mixing homogeneity in feedstuff, can play the effect of good anti-caking, and stearic acid dosage reduces.
Meanwhile it has unexpectedly been found that by stearic acid mixture of the present invention and feedstuff, especially after the mixing of lamb feedstuff, being conducive to improving
The quality of mutton of lamb.
The technical solution used in the present invention is as follows:
A kind of stearic acid mixture, including following components and its percetage by weight: stearic acid 10-35%, magnesium stearate 10-
30%th, calcium stearate 30-50%, silicon dioxide 5-10%.
Preferably, it is made up of following components and its percetage by weight: stearic acid 33%, magnesium stearate 21%, calcium stearate
40%th, silicon dioxide 6%.
Magnesium stearate density is 1.07, and fusing point is 88.5 DEG C, is slightly soluble in water, can resolve into stearic acid under strong acid environment
And magnesium ion.The stable in properties of magnesium stearate, not self-polymerization, there is the effect such as lubrication, anti-stick, fluidizer.
Fatty acid calcium is a kind of auxotype energy additive, and predominantly body provides energy, does not affect the normal life of body
Reason metabolism.In addition, fatty acid calcium can also produce favorable influence to the utilization of other nutrient substance.Calcium stearate is a kind of important
Fatty acid calcium, its ionization ph be 4.5-5, under animal small intestinal sour environment, be dissolved into stearic acid fat acid and calcium ion dissociate
Out, utilized by intestinal absorption.
Silicon dioxide is a kind of conventional wandering agent.
Present invention also offers a kind of preparation method of described stearic acid mixture, weigh the Hard Fat of corresponding weight portion first
Acid and silicon dioxide, the two adds the calcium stearate of corresponding weight portion, mixes again after being sufficiently mixed, be eventually adding corresponding weight
Part magnesium stearate mix homogeneously, obtains stearic acid mixture.
When described stearic acid mixture is applied in feedstuff, the not super feed relative of addition of stearic acid mixture
For 1%-2%.
Preferably, in feedstuff, stearic acid mixture addition is the 1.5% of feed relative.
Compared with prior art, stearic acid mixture not only has good mixing homogeneity in feedstuff to the present invention, subtracts
Lack stearic consumption, and and feedstuff, especially after the mixing of lamb feedstuff, be conducive to improving the meat production of lamb.
