Abstract
The invention relates to a preparation method of aquatic feed micro encapsulated coating amino acid. The components of the micro encapsulated coating amino acid are: 30-60 percent of glyceride, 30-60 percent of amino acid powder and 5-15 percent of stearic acid. In the method, main amino acids necessary for animals are processed by micro encapsulated coating, and therefore, the coated crystalline amino acid is kept in the coating material and do not dissolve out and lose due to the environment; and the amino acid in coating microencapsulation can be slowly released in the intestinal tracts of animals, thereby realizing the synchronous absorption of the coated amino acid and the bonded amino acid, improving the bioavailability of the crystalline amino acid by aquatic animals, lowering the feed rate and cost, and reducing the environmental pollution.
Description
Technical field
The present invention relates to a kind of novel aquatic feeds microencapsulation bag by amino acid whose manufacture method.
Background technology
Amino acid is the necessary nutritional labeling of aquatic animal to grow, and amino acid content in the raw material of aquatic product feed stuff and kind all can not satisfy the needs of aquaculture, therefore, in present aquatic feeds, generally add multiple free amino acid, but the free amino acid that adds absorbs with the amino acid that decomposes generation through feed protein asynchronous.The amino acid whose absorption of the absorption of free amino acid prior in native protein, decomposing, also influence the synchronization that other amino acid absorbs simultaneously, make amino acid whose absorbing not reach the balance complementation, cause aquatic livestock to free amino acid utilize variation so that the utilization of the whole feed protein of influence, the growth of aquatic livestock etc. is not had substantial help; In addition, the fishes and shrimps process of searching for food is slow, and the free amino acid in the feed is soluble in water, can dissolve to ooze out from feed in water, reduces amino acid whose effective rate of utilization.Studies show that at present the method that protection amino acid commonly used absorbs mainly contains the microencapsulation processing and free amino acid and carrier protein are formed compound, and latter's course of reaction complexity, cost is higher, is unsuitable for applying.For this reason, it is low to the invention provides a kind of cost, easy to prepare, homogeneous grain diameter, and feed coefficient is low, and the proteinosis rate is low, can polluted-water, a kind of aquatic feeds microencapsulation bag that is beneficial to the fishes and shrimps growth is by the preparation method of amino acid preparation.
Summary of the invention
The object of the present invention is achieved like this: a kind of production method of aquatic product feed crystal amino acid slow-releasing preparation is characterized in that it forms (by mass percentage calculate) by following material:
Glyceride 30-60%
Powder of amino acids 30-50%
Stearic acid 5-15%
Embodiments of the present invention are as follows: a kind of microencapsulation bag is by amino acid whose preparation method, it is characterized in that earlier powder of amino acids with 30-60% joins in the glyceride of heat fused (30-60%), under the 30-90rpm rotating speed, stir 20-50min, high speed dispersion, rotational speed regulation is at 1000-2000rpm, time 1-3min, carry out spray-drying after high speed dispersion is even, EAT is a normal temperature, leaving air temp normal temperature, feed rate 1-3L/min, the spray-drying thing carries out granulating and coating under 50-80 ℃, coating solution is the stearic acid ethanolic solution of 1-3%, and the time is 2-4h.
Main feature of the present invention is: it is processed that animal mainly must acidic amino acid be carried out the microencapsulation bag, make bag by after crystal amino acid be in the packaging material, because of water environment stripping loss; Granularity is suitable simultaneously, help wrapping by the amino acid in the micro-capsule and in animal intestinal, slowly discharge, can realize the bag by amino acid (methionine, lysine etc.) with combine the amino acid whose synchronous absorption of attitude, improve the bioavailability of aquatic animal to crystal amino acid, thereby improve the utilization rate of feed protein, reduce dietary protein level, save the fish meal addition, reduce fodder and bait coefficient and cost, and reduce environmental pollution or the like.
