Problems solved by technology

However, the addition of fish oil to feed also has certain application defects: because the fish oil used in the feed industry is mostly crude fish oil, which itself contains many pro-oxidative components, and the feed contains a variety of pro-oxidative factors, which makes fish oil easy to oxidize, resulting in the addition of Fish oil feed is more likely to deteriorate and difficult to preserve, thereby reducing the nutritional value of the feed, affecting the palatability, and even endangering the health of animals in severe cases; moreover, the crude fish oil has poor fluidity, and it is not easy to stir evenly during the feed production process , resulting in unbalanced distribution of fatty acids, low digestion and absorption rate, and waste of resources

Embodiment 1

[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 lipa...

Embodiment 2

[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...

Embodiment 3

[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 rea...

Abstract

The invention discloses an emulsified fish oil powder feed additive and a preparation method thereof, belonging to the field of feed additives. The invention adopts enzyme catalysis technology to prepare emulsified fish oil through the transesterification reaction of ethyl ester fish oil and glycerin, and uses puffed corn as a carrier, and after mixing and homogenizing, emulsified fish oil powder is finally prepared. The emulsified fish oil powder is used as a feed additive Adding it to livestock and poultry and aquatic feed can improve the nutritional value of the feed, and make it have good palatability, more stable storage quality, promote the absorption of fat-soluble vitamins in the feed by livestock and poultry, effectively improve the feed conversion rate and livestock The immune rate of poultry, and in aquaculture, can also improve the bait coefficient and fat utilization rate. Healthy and rapid development.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to an emulsified fish oil powder feed additive and a preparation method thereof. Background technique [0002] Marine fish oil is rich in various omega-3 polyunsaturated fatty acids such as DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid), and has extremely high nutritional value. The use of marine fish oil to produce high-quality fish oil feed additives can greatly improve the nutritional value of animal husbandry feed in my country and promote the healthy and rapid development of my country's animal husbandry industry. However, the addition of fish oil to feed also has certain application defects: because the fish oil used in the feed industry is mostly crude fish oil, which itself contains many pro-oxidative components, and the feed contains a variety of pro-oxidative factors, which makes fish oil easy to oxidize, resulting in the addition of Fish oil feed is more likely ...
