Problems solved by technology

[0002] At present, in the process of fish and shrimp farming, the main reasons why fish and shrimp cannot make full use of B group crystal vitamins are: ① fish and shrimp feed slowly, and B group crystal vitamins are easily soluble in water, and are easy to seep out from feed particles, affecting Addition effect of B group crystal vitamins
②The properties and structure of some B crystal vitamins are easily destroyed after contact with the external environment (such as VB 1 , VB 2 , VB 6 , folic acid)
During the storage of B group crystalline vitamins and aquatic feed, the properties and structure of B group crystalline vitamins are destroyed after contact with the external environment, which affects the addition effect of B group crystalline vitamins
③ Some B crystal vitamins are not resistant to high temperature (such as VB 3 , VB 7 , folic acid)
In the process of preparing aquatic feed, the temperature can reach 130°C, and crystal vitamins are easily destroyed at this temperature, which affects the effect of adding B group crystal vitamins

Abstract

The invention discloses B-family crystal vitamin microcapsules and a method for preparing the microcapsules by utilizing the solvent evaporation method. In the preparation method, raw materials comprise the following components in parts by weight: 1-1.3 parts of ethyl cellulose, 1-4 parts of Span80, 3-9.4 parts of B-family crystal vitamin, 26-47.4 parts of cyclohexane and 32-55.6 parts of dichloromethane; and the preparation method comprises the following steps: dissolving the ethyl cellulose in the dichloromethane according to the formula to get solution A; further dissolving the Span80 in the cyclohexane to get solution B, sequentially adding the solution A and the B-family crystal vitamin into the solution B under the situation of keeping the temperature of the solution B at 30 DEG C-40 DEG C, uniformly stirring till becoming thick, air-drying the thick solution, then smashing and finally getting the B-family crystal vitamin microcapsules. The vitamin microcapsules have slow-release effect and good stability, and can greatly improve the adding effect of the B-family crystal vitamin and reduce the feed cost, the method is simple, low in cost and applicable to large-scale production, and products are used for feed for fishes and shrimps and can greatly improve the cultivation benefits.
