Abstract
The invention discloses a kind of method of feedstuff mildew, in feed preparation, by chitosan oligosaccharide mould inhibitor and the corn flour crushed or other edible powder premixed, add in feed after stirring in mixer, the feed sealing of having produced is preserved; The mass percentage that chitosan oligosaccharide mould inhibitor adds is at 1-1000ppm.The method of this feedstuff mildew effectively can prevent feed mold, and mould inhibitor addition is few and cost is low, can be used in all animal feeds.
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 when mould inhibitor addition is very little.
Background technology
China's forage yield has reached about 1.5 hundred million tons, and feed easily goes mouldy in preservation process, and the consumption of mould inhibitor is very huge, allows the mould inhibitor used to be mainly propionic acid and its esters, sodium Diacetate etc. at present.Propionic acid and its esters account for about 70% 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 also remains high always, but propionic acid volatility is large, 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 comparatively large, and feed per ton needs 3000-5000 gram of sodium Diacetate, and use cost is high, and when adding too much, the palatability of feed is bad.
Dimethyl fumarate and mono-methyl are disabled mould inhibitor, but due to its anti-mold effect be the 2-6 of propionic acid and its esters doubly, be 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
For the deficiency that existing feedstuff mildew method exists, the object of the present invention is to provide one to prevent feed mold long-term effectively, component is single and addition is few, feedstuff mildew method that cost is low.
For achieving the above object, technical scheme provided by the invention is: a kind of method of feedstuff mildew, in feed preparation, by chitosan oligosaccharide mould inhibitor and the corn flour crushed or other edible powder premixed, add in feed after stirring in mixer, the feed sealing of having produced is preserved; The mass percentage 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 mass percentage 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 effectively can prevent feed mold, with low cost.This feedstuff mildew method can be applicable to all animal feeds.
Detailed description of the invention
Below by embodiment, the present invention is described further.Due to chitosan oligosaccharide molecular mass be greater than change in 2000 daltonian scopes time, anti-mold effect is more or less the same, and following examples illustrate for molecular mass 3000 dalton.
