Abstract
Application of the sorbic acid as bait drop phosphorus agent, it is related to a kind of new opplication of sorbic acid.The purpose of the present invention is to reduce the usage amount of phosphorus in existing mixed bait, to avoid causing body eutrophication, while does not influence growing for aquatic livestock again.Sorbic acid uses as the drop phosphorus agent in bait.The present invention can effectively reduce the usage amount of phosphorus in fish bait using sorbic acid, improve absorption of the aquatic products to phosphorus, utilization rate, reduce the lossing solution of phosphorus, so as to avoid body eutrophication, protect water body environment.
Description
Technical field
The present invention relates to a kind of new opplication of sorbic acid.
Background technology
More and more to the demand of aquatic products with the increasingly raising of living standards of the people, quality requirements are also increasingly
Height, the continuous expansion of aquaculture scale is promoted, especially fish culture in net pen, special aquaculture are rapidly sent out in recent years
Exhibition, intensive culture more and more higher, breed variety also increasingly enrich.Evidence suggests come from the chilled small of nature fishery resources
The natural baits such as trash fish are decayed year by year, and it is supplied stability and can not be guaranteed, and price also raises year by year.
Although mixed bait can meet the needs of growth of animal in aquaculture process, and can guarantee that the stability of supply,
But the problem of bait conversion ratio is low, nutritional ingredient molten mistake be present.P elements are the indispensable important nutrition members of aquatic livestock
Element, phosphorus must be all added in the mixed bait of most of aquatic livestock to improve the growth performance of aquatic livestock, phosphorus lacks and can caused
Aquatic livestock skeleton development is bad.However, aquatic livestock is relatively low to the utilization rate of phosphorus in bait, 50%~70% phosphorus in bait
Finally all enter water body, not only cause the waste and pollution of P elements, can also cause body eutrophication, influence water body and environment
Safety.
Sorbic acid is eaten mainly as food preservative at present, is the efficient peace of international food and agricultural organization and Health Organisation recommendations
Full antisepsis antistaling agent, it is widely used in the industries such as food, beverage, tobacco, agricultural chemicals, cosmetics；As unsaturated acids sorbic acid
It can also be used for resin, spices and rubber industry.
The content of the invention
The purpose of the present invention is to reduce the usage amount of phosphorus in existing mixed bait, to avoid causing body eutrophication, together
When again do not influence growing for aquatic livestock.
Sorbic acid of the present invention uses as sorbic acid in the application of fish bait drop phosphorus agent as drop phosphorus agent.
Phosphorus agent is dropped --- reduce the usage amount of phosphorus in bait.The present invention can be effectively reduced in fish bait using sorbic acid
The usage amount of phosphorus, aquatic products (fish) absorption to phosphorus, utilization rate are improved, the lossing solution of phosphorus is reduced, so as to avoid water eutrophication
Change, protect water body environment.
Embodiment
Technical solution of the present invention is not limited to act embodiment set forth below, in addition between each embodiment
Any combination.
Embodiment one：Present embodiment sorbic acid uses as the drop phosphorus agent in fish bait.
Present embodiment can ensure aquatic products normal growth and development, and reduce in bait 30%~60% phosphorus, improve bait
Expect coefficient, reduce water pollution risk.
Embodiment two：The difference of present embodiment and embodiment one is：The addition of sorbic acid accounts for
The 0.5%~2% of fish bait gross mass.Other steps and parameter are identical with embodiment one.
Embodiment three：The difference of present embodiment and embodiment one is：The addition of sorbic acid accounts for
The 1% of fish bait gross mass.Other steps and parameter are identical with embodiment one.
Embodiment four：The difference of present embodiment and embodiment one is：Sorbic acid flour is particle diameter
Mixed less than 40 mesh powders with other fish bait compositions.Other steps and parameter are identical with embodiment one.
