Problems solved by technology

But this process also brings the following problems: as we all know, in order to strengthen the nutrition of fish and the absorption of carotenoids, a large amount of oil is often added to fish feed. This oil is a mixture of fish oil and vegetable oil. It is added by post-spraying technology, that is, after the fish feed is extruded and puffed, a large amount of oil is sprayed on its surface. The oil is lipophilic, and the astaxanthin to be added later is dissolved in water and added. It becomes very difficult to evenly spray the astaxanthin dissolved in water on the feed particles covered with a layer of oil. The presence of hydrophobic oil on the surface of the particles makes the nano-scale astaxanthin dissolved in water enter the pores of the feed particles The resistance of the feed particles is greatly enhanced, so these astaxanthins can only be distributed on the surface of the particles and cannot enter the interior; moreover, if the astaxanthin is not completely dissolved in water, the presence of small particles will block the internal channels of the feed particles and prevent the shrimp from feeding. The cyanine penetrates into the interior of the particle and on

Embodiment 1

[0039] Preparation of Astaxanthin 20% Oil Suspension

[0040] Weigh 2.2kg of pure astaxanthin (content: 97.2%), 0.3kg of natural vitamin E and 5.0kg of sunflower oil, mix evenly, put it in a ball mill and grind it for 1.5hr, take it out to get a viscous fluid, and then add 2.5kg Sunflower oil, stirred and mixed evenly to obtain a suspension of astaxanthin oil with better fluidity.

[0041] The content of astaxanthin in the oil suspension is 21.2% as measured by ultraviolet spectrophotometry, and the average particle diameter of the particles in the oil suspension is 4.68 μm as measured by a laser particle size distribution analyzer.

[0042] Dissolution of astaxanthin before spraying

[0043] Take 8.0kg of the above-mentioned astaxanthin oil suspension and mix it with a part of 4800kg of oils to be added (a mixture of fish oil and soybean salad oil, their ratio is 2:1), heat up to 60°C and keep it warm for 1.5hr while stirring. Suspended astaxanthin particles are fully disso...

Abstract

The invention provides a carotenoid preparation which relates to oil suspension, a feed which contains the carotenoid preparation, a method used for preparing the feed, and the use as additives of animal feed, food, cosmetics and/or medicines used for the carotenoid preparation. Effective compositions in the feed grains are uniformly distributed; furthermore, most of the effective compositions are distributed in the grains, thus reducing the surface oxidation loss; the carotenoid exists in a dissolved state, thus being beneficial for the absorption and utilization of animals; the animal testsalso show that the coloring effect of the fish is extremely good after the feed grains are used for feeding the fish.

Description

technical field [0001] The present invention relates to a new formulation of carotenoids, in particular to carotenoid preparations in oil suspension, feed containing said carotenoid preparations, methods for preparing said feed, and carotenoid preparations for use in animals The use of additives for feed, food, cosmetics, and / or pharmaceuticals. Background technique [0002] According to the presence or absence of oxygen atoms in the molecular structure formula, carotenoids can be divided into two categories, namely carotene and lutein. The former has no oxygen atom in the molecular structure formula, such as β-carotene, lycopene The structural formula of the latter contains hydroxyl or carbonyl, or contains these two oxygen-containing functional groups, such as canthaxanthin, lutein, astaxanthin, zeaxanthin, etc. Among the carotenoids of the lutein group, if only hydroxyl groups are contained in the molecular structure formula, they tend to show yellow color, and if there ...
