Abstract
The utility model relates to a method of preparing the methionine micro capsules used in aquatic feed by means of spray drying, which belongs to the technical field of the aquatic feed. The utility model uses the maltodextrin as wall material, uses the methionine as core material, and prepares the methionine micro encapsules products by means of the spray drying. The utility model carries through the micro encapsulation process to the methionine, makes the crystal methionine in the feed released slowly in the intestinal tract of a shrimp, thereby realizes a synchronous absorption of the crystal methionine and the incorporated methionine; the utility model can reduce the usage amount of the fishmeal, increase the usage amount of the vegetable protein material with a lower price, and reduce the feed cost.
Description
Technical field
A kind of method of utilizing the spray drying method for preparation methionine microcapsule for marine product feedstuff belongs to the aquatic feeds technical field.
Background technology
At present, because animal protein resource such as fish meal etc. relatively lack, generally use grouts partly to substitute fish meal in mixed feed, it is serious to make that essential amino acid lacks, and gives therefore that to add essential amino acid in the feed be one of method that improves protein nutritive value.Research data shows no matter be juvenile prawn or become shrimp they all are difficult to utilize crystalline amino acid in the feed.And in feed, add crystalline amino acid, do not have facilitation effect for the shrimp growth, institute think make the shrimp feed reach amino acid balance just must the higher imported fish meals of a large amount of use methionine contents.This causes the shrimp feed cost higher, has influenced the economic benefit of shrimp aquaculture.If can carry out microencapsulation to methionine handles, crystal methionine in the feed can slowly be discharged in the shrimp enteron aisle, thereby realize crystal methionine and the synchronous absorption that combines the attitude methionine, so just can reduce the use amount of fish meal, increase the use amount of the more cheap plant proteins raw material of price, reduce feed cost.
Up to now, the report that microencapsulation amino acid is applied to aquatic livestocks such as shrimp feed is also fewer, but it is a lot of to be applied to the report of ruminant aspect.Because digestion of aquatic livestocks such as shrimp and nutrition aspect and other animals have a great difference, so be necessary to carry out the amino acid whose research of shrimp special slow release, so just can make amino acid additive be applied to the shrimp feed widely, reduce feed cost.
The present invention utilizes spray drying process to produce methionine microcapsule in a large number, can add on a large scale in the aquatic feeds, can significantly improve the aquatic feeds quality, reduce feed cost, for the level of processing that improves China's aquatic feeds is very useful, and can produce very big economic benefit.Therefore preparation method provided by the invention is fit to batch production large-scale production, and product is applied to the commercial sized prawn feed, improves culture benefit.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing the spray drying method for preparation methionine microcapsule for marine product feedstuff, methionine is carried out microencapsulation to be handled, crystal methionine in the feed can slowly be discharged in the shrimp enteron aisle, thereby realize crystal methionine and the synchronous absorption that combines the attitude methionine, can reduce the use amount of fish meal, increase the use amount of the more cheap plant proteins raw material of price, reduce feed cost.
Technical scheme of the present invention: a kind of method of utilizing the spray drying method for preparation methionine microcapsule for marine product feedstuff is the wall material with the maltodextrin, is core with the methionine, utilizes spray-drying to prepare the methionine microcapsule product; Technology is: maltodextrin adds in the entry, heating for dissolving, cooling then, feeding quantity adds methionine then for control solution viscosity 150-180mP.s, the weight ratio of methionine and maltodextrin is 0.5: 1～5: 1, the suspension solid concentration is 100g/L～400g/L, and the spray-drying condition is: 220～230 ℃ of EATs, charging rate 200～220mL/h, nozzle diameter 0.5mm carries out spray-drying.
Beneficial effect of the present invention: the present invention carries out microencapsulation to methionine and handles, crystal methionine in the feed can slowly be discharged in the shrimp enteron aisle, thereby realize crystal methionine and the synchronous absorption that combines the attitude methionine, can reduce the use amount of fish meal, increase the use amount of the more cheap plant proteins raw material of price, reduce feed cost.The consumption of methionine microcapsule is 0.01%～1% of a feed weight.
