Abstract
The invention discloses a feed mildew resisting method. During the feed production process, a chitosan oligosaccharide mildew resistant agent is pre-mixed with grinded corn flour and other edible powder, then the mixture is stirred and mixed in a stirrer, then the mixture is added into the feed, and finally the finished feed is sealed and preserved; wherein the mass percentage content of the added chitosan oligosaccharide mildew resistant agent is 1 to 1000 ppm. The feed mildew resisting method can effectively prevent feed mildew, contains little additive, has a low cost, and can be applied to every animal feed.
Description
Technical field
The present invention relates to a kind of method of feedstuff mildew, this mold-proof method just can play the effect of fresh-keeping mildew-resistant in the situation that mould inhibitor addition is very little.
Background technology
China's forage yield has reached 1.5 hundred million tons of left and right, and feed easily goes mouldy in preservation process, and the consumption of mould inhibitor is very huge, and the mould inhibitor that allows at present to use is mainly propionic acid and its esters, sodium Diacetate etc.Propionic acid and its esters account for 70% left and right of market mould inhibitor total amount, China's propionic acid very low from output, and the production of propionic acid is mainly the enterprises such as BASF and monopolizes in the world, price is also always high, but propionic acid volatility is large, and excitant is strong, also larger to the corrosivity of equipment.Sodium Diacetate is a kind of New Type Antiseptic Germicide of introducing to the market in recent years, although overcome the above-mentioned deficiency of propionic acid, its addition is larger, and feed per ton needs 3000-5000 gram of sodium Diacetate, and use cost is high, and adds when too much, and the palatability of feed is bad.
Dimethyl fumarate and mono-methyl are disabled mould inhibitor, but due to its anti-mold effect be propionic acid and its esters 2-6 doubly, be the more than ten times of sodium Diacetate, price is cheap again, usually used secretly by some enterprise, but they has strong sensitization to skin.
Summary of the invention
The deficiency existing for existing feedstuff mildew method, the object of the present invention is to provide one to prevent long-term effectively feed mold, the feedstuff mildew method that component is single and addition is few, cost is low.
For achieving the above object, technical scheme provided by the invention is: a kind of method of feedstuff mildew, in Feed Manufacturing process, by chitosan oligosaccharide mould inhibitor and the corn flour or other edible powder premixed that crush, after stirring in mixer, add in feed, the feed sealing of having produced is preserved; The quality percentage composition that described chitosan oligosaccharide mould inhibitor adds is at 1-1000ppm.
Wherein, this chitosan oligosaccharide mould inhibitor is made up of chitosan oligosaccharide one-component, and the molecular mass of described chitosan oligosaccharide is more than 2000 dalton.
Wherein, the quality percentage composition that described corn flour or other edible powder add is 2.5%.
The present invention has following beneficial effect: in this feedstuff mildew method, mould inhibitor is made up of one-component, and non-stimulated, addition is few, and only 1-1000ppm just can effectively prevent feed mold, with low cost.This feedstuff mildew method can be applicable to all animal feeds.
The specific embodiment
Below by embodiment, the present invention is described further.Because chitosan oligosaccharide molecular mass is being greater than while changing in 2000 daltonian scopes, anti-mold effect is more or less the same, and following examples illustrate as an example of molecular mass 3000 dalton example.
