Embodiment 1

[0024] 5 kg of 95% (volume) ethanol and 3 kg of ethyl acetate mixed solution, heated at a temperature of about 60 ° C, adding 1 kg of lutein crystals with a content of 72% (weight), stirring and mixing at 1000-1200r / min for 20 minutes, lutein After the element crystals are completely dissolved, add 3 kg of polyethylene glycol glycerol ricinoleate, 1 kg of Tween 40, fully stir and mix for 50 minutes, add 5 kg of white carbon black, stir and mix, then add 54 kg of calcium carbonate powder, stir and mix Finally, obtain 72 kilograms of content and be 1% special-purpose lutein of aquatic products turn yellow feed.

Embodiment 2

[0026] 50 kg of ethyl acetate solution, heated to 55°C, added 10 kg of 81% lutein crystals, stirred and mixed at 1000-1200r / min for 15 minutes, after complete dissolution, added 10 kg of Span 20 and 8 kg of Tween 60, Fully stir and mix, add 40 kg of white carbon black, stir and mix, then add 100 kg of defatted rice bran and 197 kg of calcium carbonate powder to obtain 405 kg of lutein for aquatic yellowing feed with a content of 2%.

Embodiment 3-6

[0028] According to the method of Example 1, the special lutein for aquatic yellow turning feed was prepared, and the various components and dosages were as follows.

Abstract

The invention discloses a modified xanthophyll production method which comprises the following steps: adding a xanthophyll crystal into an organic solvent under the heating condition, intensely stirring for 10-30min, adding a surfactant, intensely stirring for 10-60min, adding white carbon black, stirring to obtain solid powder, adding a carrier, and continuously intensely stirring for 0.5-2h to obtain water-soluble modified xanthophyll. The modified xanthophyll product prepared by adopting the production method is added in an aquatic feed and has the remarkable effect on transforming aquatic products into the xanthophyll, the consumption of a modified xanthophyll additive required to be charged is small, the xanthophyll transforming speed is high, toxic and side residues are free, and the absorption of other nutritional ingredients is not influenced.

Description

technical field [0001] The invention mainly relates to a preparation method of a special feed additive for animal feed, in particular to a production process of modified lutein and its application in aquatic feed. Background technique [0002] Lutein is a kind of carotenoid, which widely exists in the petals, stems and leaves of plants. Its health effects on human body include preventing vision loss, anti-aging, anti-cancer, and preventing cardiovascular diseases. It is also widely used in animal breeding. It is used for coloring and improving the quality of livestock products in fish, shrimp, chicken and eggs. The molecular formula is C 40 h 56 o 2 , whose structural formula is shown in Formula I. [0003] [0004] Formula Ⅰ [0005] The European Union has been permitting natural lutein to be used in aquatic products and poultry feeds, and China has only permitted poultry feeds in the past, but in July 2013 the Ministry of Agriculture released the "Feed Additives Var...
