Emulsified fish-oil powder feed additive and preparation method thereof

[0024] This embodiment discloses a kind of emulsified fish oil powder, is made by following method:

[0025] A. Transesterification reaction: Weigh 50kg of ethyl ester fish oil, 7kg of glycerin, 5kg of 435-type lipase, 0.5kg of pancreatic lipase, and 1g of konjac powder, and add the materials into a closed reaction kettle with a built-in mesh bucket and mix them Stir and heat to make the temperature in the kettle be 83°C, connect the reactor to a vacuum pump to make the inside of the kettle a vacuum environment, and the pressure is 500Pa. Using high vacuum conditions, the ethanol generated by the reaction is separated and extracted from the reaction system in time, and the reaction tank is connected to the reactor. Condenser recovery ethanol, stirring reaction 20h, stop reaction;

[0026] B. Filtration: The emulsified fish oil generated by the reaction in step A is fine-filtered through a micron filter, put into the oil storage tank for temporary storage, and the 435-type lipase

[0029] This embodiment discloses a kind of emulsified fish oil powder, is made by following method:

[0030] A. Transesterification reaction: Weigh 100kg of ethyl ester fish oil, 16kg of glycerin, 13kg of 435-type lipase, 1kg of pancrelipase, 1.5g of konjac powder, and add the materials into a closed reaction kettle with a stirrer built in a net bucket and mix them Stir and heat to make the temperature in the kettle be 85°C, connect the reactor to a vacuum pump to make the inside of the kettle a vacuum environment, and the pressure is 500Pa. Using high vacuum conditions, the ethanol generated by the reaction is separated and extracted from the reaction system in time, and the ethanol that is connected to the reactor is used. Condenser recovery ethanol, stirring reaction 18h, stop reaction;

[0031] B. Filtration: The emulsified fish oil generated by the reaction in step A is fine-filtered through a micron filter, put into the oil storage tank for temporary storage, and the 435-ty

[0034] This embodiment discloses a kind of emulsified fish oil powder, is made by following method:

[0035]A. Transesterification reaction: Weigh 100kg of ethyl ester fish oil, 20kg of glycerin, 15kg of 435-type lipase, 1kg of pancrelipase, 1.6g of konjac powder, and add the materials into a closed reaction kettle with a stirrer with a built-in net bucket and mix them. Stir and heat to make the temperature in the kettle be 87°C, connect the reactor to a vacuum pump to make the inside of the kettle a vacuum environment, and the pressure is 500Pa. Using high vacuum conditions, the ethanol generated by the reaction is separated and extracted from the reaction system in time. Condenser recovery ethanol, stirring reaction 23h, stop reaction;

[0036] B. Filtration: The emulsified fish oil generated by the reaction in step A is fine-filtered through a micron filter, put into the oil storage tank for temporary storage, and the 435-type lipase is retained in the net barrel of the reacti
