Example Embodiment

[0017] Example 1

[0018] (1) Add 15g of starch and 1500ml of water to a container, heat and stir to 100°C, cool to 40°C, and then slowly add 22.5g of sodium alginate until it is completely dissolved in water;

[0019] (2) Then put the bait to be embedded in the following order vitamins: 1.240g, fish meal: 111.6g, casein: 80.6g, squid meal: 18.6g, fish oil: 46.5g, soybean lecithin: 9.3g, lure Agent: 0.775g, mineral salt: 15.5g, choline: 0.341g in sodium alginate starch solution, and stir evenly.

[0020] (3) The above-mentioned uniformly stirred solution is sprayed with a spray gun (with a nozzle diameter of 2mm and a pressure of 0.2Mpa) to form tiny mist droplets, and in 2% CaCl 2 Gelation in the aqueous solution, and the particle size is 50-150μm under a microscope.

[0021] (4) Vacuum filtration and separation;

[0022] (5) The filter cake is freeze-dried at -58℃ to make a dry product;

[0023] (6) The powdered product is 280.68 g, and the yield is 91%.

Example Embodiment

[0024] Embodiment two:

[0025] (1) Add 7.5g of starch and 1500ml of water to a container, heat and stir to 100°C, cool to room temperature, and then completely dissolve 30g of sodium alginate in 1500ml of water;

[0026] (2) Then place the bait to be embedded vitamins in the following order: vitamins: 1.28g, fish meal: 115.2g, casein: 83.2g, squid meal: 19.2g, fish oil: 8.32g, cellulose: 5.44g, soybean lecithin :35.2g, food attractant: 0.8g, mineral salt: 16g, choline: 0.352g in the sodium alginate solution, stir well.

[0027] (3) The above-mentioned uniformly stirred solution is sprayed with a spray gun (nozzle diameter of 1mm, pressure 0.5Mpa) to form tiny mist droplets, and in 0.1% CaCl 2 Gelation in ethanol solution, and the particle size is 50-150μm under microscope.

[0028] (4) Centrifugal separation to obtain the initial product of open bait;

[0029] (5) Use 78℃, 0.01Mpa vacuum drying to make dry products;

[0030] (6) After crushing and sieving, the product is 295.60 g...

Abstract

The invention belongs to a preparation method of high economic fish micro-spheres opening bait, specifically it uses sodium alginate and starch as micro-spheres binding material and embeds bait nutritional component through air and mist means. It protects vitamins, proteins, inorganic salts and other material components away the influence and interreaction of heat, moisture, oxygen, ultraviolet rays and metallic ion during the process of processing, storing, transporting and feeding. It controls the particle diameter of opening bait using micro-spheres particle diameter to fitting the first ingress of fish fry. It could reduce loss rate of bait nutrient components in water, maintain water clean, improve survival rate of economic fish seedlings and reduce the production costs of artificial breading.

Description

technical field [0001] The present invention relates to a kind of preparation method of high economical fish microsphere opening bait, it utilizes microsphere particle diameter to control the size of opening bait particle diameter, to be suitable for fish seedlings (especially artificially hatched high economical fish seedlings) ) open bait for the first time. The open bait prepared by the microsphere method can not only provide balanced nutrients for the growth of fish seedlings, but also reduce the dissolution rate of bait nutrients in water, maintain clean water, improve the survival rate of high-economic fish seedlings, and reduce artificial feeding. High economic fish production costs. Background technique [0002] Due to the natural habits of high-economic fish (such as: carnivorous fish such as flounder), the first opening of newly hatched fish is often passive, and the food will be high animal protein. Usually in the natural state, the mortality rate of its juvenil...
