Abstract
A feed containing chitosan additive and adhesive for improving water quality and the quality of meat is prepared by the unique solid reaction. It contains the main material and the mixture of chitosan additive and chitosan adhesive.
Description
Technical field
The present invention relates to a kind of feed and preparation method thereof and application, particularly relate to a kind of feed that contains shitosan additive and binding agent and preparation method thereof and application.
Background technology
Herding, aquatic products industry are the mainstay industries of China's agricultural always.Along with the guiding of market economy and popularizing and using of breed science and technology, China livestock and poultry, aquatic products enrich, the situation that supply exceed demand appears frequently, herding, aquatic products market turn to the buyer's market by the seller's market, turn to the consumption general layout of mass type by scalar type, wherein the security of livestock and poultry, aquatic products has become the focus that people pay close attention to.Harmful substance is residual in herding, the aquatic products is on the rise, and human health has been constituted become the side of body.Moreover, occurring after the China joined WTO that herding, aquatic products tariff descend and situation that the trade technology barriers are strengthened, the production cost of China's herding, aquatic products and price advantage are difficult to keep out the negative effect of its health inferior position.The enrichment of harmful heavy metal in livestock and poultry, aquatic products is a great problem that influences the livestock products security at present.China's industrial boom, and " three wastes " handle as yet not really solution, severe contamination agricultural environment; Contain the agricultural chemicals of heavy metal, a large amount of uses of chemical fertilizer; The unreasonable exploitation mineral resources in some areas, these all cause the heavy metal pollution of soil, waters and feedstuff.Animal can concentrate thousands of tens thousand of times with the heavy metal in feed and the drinking-water, thereby make heavy metal become more and more serious problem to the pollution of livestock and poultry, aquatic products by biological accumulation and biological concentration process.
The producer that produces feed addictive at present both at home and abroad is more, but owing to adopt artificial synthetic chemical industry crystalline substance mostly, the product toxic and side effect is big, and is residual many in the body, and environment and people are had certain pollution, and this utmost point is not suitable for the trend of current animal-breeding greenization.Therefore it is very necessary to develop the pure natural fodder additive with certain effect.
Shitosan (chemistry by name (1,4)-and 2-amino-2-deoxidation β-d glucan) contain active hydroxyl and amino isopolarity group in the molecule, shitosan is the cation edibility fiber of the unique existence of occurring in nature, it have promote cell division with growth, strengthen beneficial bacterium in the intestines, suppress harmful bacterium, reinforced immunological function, reinforcement liver function, physiological effect such as anti-infective.Experiment confirm adds a small amount of shitosan in feed, can improve the result of use of feed.And, be made into the aqueous solution with shitosan and can be used as feed adhesive and improve the stabilization time of feed in water.
The present invention adapts to the product of this background just.In order to solve the problem that present feedstuff industry exists, improve the competitiveness of homemade feed, the inventor is based on abundant practical experience and professional knowledge, actively studied innovation, through constantly research, test, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
Summary of the invention
Main purpose of the present invention is, overcome the defective that exists in the existing feedstuff industry, and a kind of novel feed that contains shitosan additive and binding agent and preparation method thereof and application, technical problem underlying to be solved are provided is to make it have good adhesive property and excellent green health effect.
Another object of the present invention is to, a kind of feed that contains shitosan additive and binding agent is provided, technical problem to be solved is to improve the ability of the environment purification of feed, strengthens the immunocompetence and the antibacterial ability of being raised object.
A further object of the present invention is, a kind of feed that contains shitosan additive and binding agent and preparation method thereof and application are provided, technical problem to be solved is that feedstuff industry is reduced production costs, and is that homemade feed has more practicality and competitiveness, and has the value on the industry.
Purpose of the present invention and to solve its technical problem underlying be to adopt following technical scheme to realize.A kind of feed that contains shitosan additive and binding agent according to the present invention's proposition, comprise premix and batching, wherein the quality proportioning of premix and batching is 2: 8-1: 9.5, contain the shitosan additive and the shitosan binding agent that obtain by following method in the premix;
At first shitosan dissolved, after the removal of impurities, precipitation, filtration, drying, carry out solid phase reaction with glutamic acid, the product that obtains is pulverized and is promptly obtained this feed adhesive.
The shitosan additive can make by following method: at first shitosan and the aldehyde that contains carboxyl, hydroxyl hydrophilic group are carried out the derivative that substitution reaction obtains soluble chitosan, after this derivative further carries out the solid phase reduction reaction with reducing agent, with the derivative as shown in the formula (I) that obtains, the further oxydrolysis of this derivative promptly obtains this shitosan additive.
Wherein R is the aldehyde that contains carboxyl, hydroxyl hydrophilic group, and n is between 500～5000.
The mass percent 1%～5% of shitosan binding agent in premix wherein, the mass percent of shitosan additive in premix is 0.05 ‰～0.3 ‰;
Wherein batching is conventional batching.
The object of the invention to solve the technical problems can also be further achieved by the following technical measures.
The aforesaid feed that contains shitosan additive and binding agent, wherein said shitosan are deacetylation 70%～90%, viscosity is not less than 300 centistokes(cst)s, molecular weight 500,000～600, the shitosan between 000.
