Problems solved by technology

[0005] Although the fat products for seawater fish disclosed in the prior art can improve feed efficiency to a certain extent, are safe and efficient, and have no toxic and side effects, they cannot significantly reduce the fatty liver of seawater fish and improve the quality of breeding. Therefore, a It is very necessary to use fat products specially for sea fish, which can significantly reduce their fatty liver, promote the growth and development of fish, increase the production of aquaculture, and improve the quality of aquaculture.

preparation example 1

[0052] This preparation example provides a kind of microbial grease I, and its preparation method is as follows:

[0053] (1) Thraustochytrium was inoculated in the fermentation medium with an inoculation amount of 10%, and fermented at 35° C. with an initial pH value of 6.0 for 72 hours to obtain a fermented liquid, which was filtered to obtain a concentrated fermented liquid; wherein the fermented medium The formula consists of glucose 50-60g / L, corn syrup 1-5g / L, potassium dihydrogen phosphate 0.1-0.5g / L, sodium chloride 10-15g / L, and the balance is water;

[0054] (2) Swell the concentrated fermented liquid obtained in step (1) at 50°C for 18 hours, and then dry at 80°C to obtain dry bacteria powder;

[0055] (3) The dry bacterial powder obtained in step (2) is crushed and broken, extracted with n-hexane for 8 hours, and 8 L is used for every kg of broken dry bacterial powder, and then vacuum precipitation to obtain the microbial oil.

preparation example 2

[0057] This preparation example provides a kind of microbial grease II, and its preparation method is as follows:

[0058] (1) Thraustochytrium was inoculated in the fermentation medium with an inoculation amount of 10%, and fermented for 100 hours at 30°C with an initial pH value of 5.0 to obtain a fermented liquid, which was filtered to obtain a concentrated fermented liquid; wherein the fermented medium The formula consists of glucose 50-60g / L, corn syrup 1-5g / L, potassium dihydrogen phosphate 0.1-0.5g / L, sodium chloride 10-15g / L, and the balance is water;

[0059] (2) Swell the concentrated fermented liquid obtained in step (1) at 40°C for 24 hours, and then dry at 75°C to obtain dry bacteria powder;

[0060] (3) The dried bacteria powder obtained in step (2) was crushed to break the wall, extracted with methanol for 6 h, and 10 L was used per kg of the broken wall dried bacteria powder, and then vacuum precipitation was carried out to obtain the microbial oil.

preparation example 3

[0062] This preparation example provides a kind of microbial grease III, and its preparation method is as follows:

[0063] (1) Thraustochytrium was inoculated in the fermentation medium with an inoculation amount of 10%, and fermented at 40° C. with an initial pH value of 7.4 for 80 hours to obtain a fermented liquid, which was filtered to obtain a concentrated fermented liquid; wherein the fermented medium The formula consists of glucose 50-60g / L, corn syrup 1-5g / L, potassium dihydrogen phosphate 0.1-0.5g / L, sodium chloride 10-15g / L, and the balance is water;

[0064] (2) Swell the concentrated fermented liquid obtained in step (1) at 60°C for 12 hours, and then dry at 85°C to obtain dry bacteria powder;

[0065] (3) The dried bacteria powder obtained in step (2) was crushed to break the wall, extracted with petroleum ether for 12 hours, and 5 L was used for every kg of the broken wall dried bacteria powder, and then vacuum precipitated to obtain the microbial oil.

Abstract

The invention relates to special fat powder for marine fishes and a preparation method and application of the special fat powder. The special fat powder for the marine fishes is prepared from microbial oil, phospholipid oil, micro seaweed meal, an emulsifier, an antioxidant and a carrier. The preparation method comprises the following steps: (1) heating the phospholipid oil, mixing the heated phospholipid oil with the microbial oil and the emulsifier, and carrying out high-pressure homogeneous emulsification treatment; (2) spraying an emulsion obtained in the step (1) onto the carrier in vacuum; and (3) mixing solid powder obtained in the step (2) with the micro seaweed meal and the antioxidant to obtain the special fat powder for the marine fishes. The special fat powder for the marine fishes is balanced in nutrition; the growth and development of the marine fishes are promoted in a nutrition intake manner, the culture yield is increased, the culture quality is improved, resources aresaved, and the economic benefit is increased; furthermore, the in-vivo fat storage of the marine fishes is reduced, and the fatty liver is reduced; and the intestinal health of the marine fishes is regulated, the immunity of the marine fishes is improved, and the survival rate is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a fat powder and its preparation method and application, in particular to a special fat powder for seawater fish and its preparation method and application, in particular to a kind of fat powder which can reduce the fatty liver of seawater fish and promote the growth of seawater fish. Fat powder for growth and development, its preparation method and application. Background technique [0002] Fat is an important nutrient for marine fish, and fat plays an important role in the growth and development, physiological metabolism and energy storage of fish. As an organic solvent, fat can promote the absorption of fat-soluble substances in the body. Fat with the same quality has higher energy than protein and sugar, and provides growth energy and essential fatty acids for marine fish. If the fat in the fish feed does not meet the requirements, it will have a great impact on the growt...
