Embodiment 1

[0034] Please refer to figure 1 , which is a production method of special bacteriostatic additive for aquatic products provided by the invention.

[0035] The production method of a kind of special bacteriostatic additive for aquatic products provided by the invention comprises:

[0036] Step S1: Provide glyceryl butyrate as a core material, and glyceryl butyrate is ultrafinely pulverized, and the pulverized particle size is 200-400 μm, preferably 200 μm. Superfine crushing refers to the operation technology of crushing the material particles above 3 mm to micron level by using mechanical or fluid power methods to overcome the internal cohesion of solids and crush them. The relevant equipment and methods will not be repeated here.

[0037] Step S2: Provide a colloidal aqueous solution having carrageenan and gelatin as a wall material coating, specifically mixing carrageenan and gelatin in an appropriate amount of water according to a weight ratio of 1:2 to 1:5 to form a collo...

Embodiment 2

[0044] In the above step S1, glyceryl butyrate with a total weight of 10 kg is used as the core material, and glyceryl butyrate is subjected to ultrafine pulverization treatment, and the pulverized particle size is 300 μm.

[0045] In the above step S2, a colloidal aqueous solution of 0.025 kg carrageenan plus 0.05 kg gelatin is used as wall material coating.

[0046] In the above step S3, when making butyrin microcapsules, hot air is directly blown into the container regardless of stages, the air inlet temperature is 200°C, and the outlet air temperature is 70°C.

[0047] When in use, the wrapped butyrin microcapsules are mixed with molasses on the shrimp feed, the dosage is 1.0% of the shrimp feed, once a day, used continuously for 5 days, and the pH value of the water body for raising shrimp is 8.0.

Embodiment 3

[0049] In the above step S1, glyceryl butyrate with a total weight of 20 kg was used as the core material, and the particle size was finely pulverized to 400 μm.

[0050] In the above step S2, a colloidal aqueous solution of 0.125 kg carrageenan plus 0.5 kg gelatin is used as wall material coating.

[0051] In the above step S3, when making butyrin microcapsules, hot air is directly blown into the container regardless of stages, the air inlet temperature is 200°C, and the outlet air temperature is 70°C.

[0052]When in use, the wrapped butyrin microcapsules are mixed with molasses on the shrimp feed, the dosage is 0.5% of the shrimp feed, once a day, used continuously for 6 days, and the pH value of the water body for raising shrimp is 7.8.

[0053] The invention provides a special antibacterial additive for aquatic products, which is obtained through the production method of the special antibacterial additive for aquatic products.

[0054] Compared with the prior art, the pr...

Abstract

The invention discloses a special aquatic product antibacterial additive and a production method thereof. The production method comprises the following steps: performing super-micro crushing treatmenton butyrin serving as core material; providing a colloid solution comprising carrageenan and gelatin as a wall coating; wrapping the core material with the wall coating, thereby obtaining butyrin microcapsules, namely the special aquatic product antibacterial additive. As the butyrin is wrapped by the wall coating of the special aquatic product antibacterial additive, a function of slowly releasing butyrin is achieved, the stability of the butyrin in water is improved, the butyrin is prevented from being dissolved in water before being taken by aquatic animals, and the problem that the effectof the butyrin is sharply degraded as the butyrin in the prior art is soluble in water is solved.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a special antibacterial additive for aquatic products and a production method thereof. Background technique [0002] The use of antibiotics in feed is increasingly restricted due to food safety and bacterial resistance concerns. The issue of antibiotics is one of the biggest challenges facing the feed and farming industry today. Although the use of antibiotics can be reduced by improving feeding management measures and adding probiotics, we need more effective measures to replace antibiotics. [0003] Short- and medium-chain fatty acids and their derivatives are normal metabolites of the animal body, and they have unique advantages in inhibiting Gram-positive and Gram-negative bacteria. Short- and medium-chain fatty acids and their derivatives refer to C1-14 fatty acids, fatty acid salts, and fatty acid glycerides. [0004] Research and practice have shown that short-chai...
