Embodiment 1

[0061] A. The preparation method of glycerol phosphatidylcholine: at a temperature of 35° C., take 500 g of phosphatidylcholine, dissolve it in 10000 ml of ethanol, add 250 ml of sodium methoxide ethanol (35% mass fraction) solution, react for 6 hours, and evaporate the solvent. 440 g of a reaction product containing glycerol phosphatidylcholine was obtained. After testing, the content of glycerol phosphatidylcholine in the reaction product was 83.4%.

[0062] B. The preparation method of acetylated phosphatidylethanolamine: take 100g of phosphatidylethanolamine, add 5g of acetic anhydride, the reaction temperature is 72°C, and the reaction time is 30min. After the acylation is completed, 1 g (30% mass fraction) of sodium hydroxide solution is added for neutralization. The oil phase was separated with n-hexane, cold analysis and filtration in cold acetone at 5°C, and the oil phase was extracted again with cold methanol at 5°C, and the insoluble part was 40 g of acetylated phos...

Embodiment 2

[0064] Take 100g of soybean oil bottoms, add 50ml of sodium methoxide ethanol (35% mass fraction) solution, react at 65°C for 6h, evaporate the solvent, and adjust to neutral with acetic acid. Then add 5g of acetic anhydride, raise the temperature to 72°C, and the reaction time is 30min. The final analysis determined that the content of glycerol phosphatidylcholine in the product was 4.13%, and the content of acetylated phosphatidylethanolamine was 1.86%, so that a feed additive with a weight ratio of glycerol phosphatidylcholine:acetylated phosphatidylethanolamine of 2.22:1 was obtained.

Embodiment 3

[0066] Take 200g of soybean lecithin oil, add 400ml of sodium methoxide ethanol (35% mass fraction) solution, react at 60°C for 5.5h, evaporate the solvent, and adjust to neutral with acetic acid. Then add 11g of acetic anhydride, raise the temperature to 70°C, and the reaction time is 45min. Final analysis determined glycerol phosphatidylcholine (20.68%) and acetylated phosphatidylethanolamine (9.02%) to obtain a feed additive with a weight ratio of glycerol phosphatidylcholine: acetylated phosphatidylethanolamine of 2.29:1.

Abstract

The invention relates to a feed additive with a function of replacing fish oil and a preparation method thereof. The feed additive contains L-alpha glycerylphosphorylcholine and acylated phosphatidylethanolamine, wherein the weight ratio of the L-alpha glycerylphosphorylcholine to the acylated phosphatidyl ethanolamine is 1:1 to 5:1, and the acylated phosphatidyl ethanolamine is preferably acetylizated phosphatidyl ethanolamine. The feed additive of the invention can realize the advantages of uniform mixing with existing feeds. The feed additive has good dispersity in water. The feed additivecan completely replace fish oil. When feeding aquatic animals, the feed additive of the invention can enrich EPA and DHA in the aquatic animals.

Description

technical field [0001] The invention relates to a feed additive, more specifically, to a feed additive with the function of replacing fish oil. Background technique [0002] 3%-5% fish oil is usually added to aquatic feed, because fish oil has the functions of improving feed nutrition, promoting biological growth, improving the meat quality of aquaculture fish, livestock and poultry, and preventing excessive fat in animals. It is enriched in the living body, so that the content of DHA and EPA in biological products is higher, such as eggs with high DHA. However, the cost of fish oil is relatively high, and often fish oil is only used in the early stages of animal growth. At the same time, the content of unsaturated fatty acids in fish oil is high. How to prevent the oxidation of fish oil is also a major obstacle to the use of fish oil. [0003] Phospholipids are complex lipids containing phosphoric acid that exist in plants and animals. At present, the phospholipids used i...
