Embodiment 1

[0033] (1) Oil extraction to extract lutein and nutrients

[0034] Put 15 parts of fish oil into the steam pot, slowly add 8 parts of marigold petal powder, stir while heating, stop heating after raising the temperature to 75°C, keep warm and stir for 2 hours, and then stop heating to obtain the extract; among them, The fish oil is preferably refined winterized fish oil; the marigold petal powder is prepared by the following method: removing flower stem buds from freshly picked marigolds, drying the petals in the air for 8-10 hours, and crushing through a 100-mesh sieve.

[0035] (2) Separation of extract

[0036] The extraction solution obtained in step (1) was left to stand for 24 hours and then divided into upper and lower layers. First, the supernatant was extracted, and then the product in the lower layer was passed through a 300-mesh screen, squeezed and filtered, and the obtained filtrate was the same as the obtained product. The above supernatants are mixed to obtain ...

Abstract

The invention discloses a feed additive containing natural lutein and a preparation method thereof. The feed additive is prepared by emulsifying an aqueous phase and an oil phase, wherein the weight part ratio of the oil phase to the aqueous phase is (2.7-3.3):7; the aqueous phase is prepared by mixing deionized water and disodium hydrogen phosphate, and the weight volume ratio of the disodium hydrogen phosphate to the deionized water is 1g: (650-750)L; and the oil phase is prepared by mixing extracted oil, Tween-80 and glycerin monostearate in a weight part ratio of (38-42):(7-11):(10-14), wherein the extracted oil is prepared from the following raw materials in part by weight: 15 to 25 parts of fish oil or plant oil, and 8 to 15 parts of marigold petal powder. In the preparation method,the fish oil or the plant oil is taken as a carrier of a marigold extract, can fully extract effective ingredients of marigolds, and play a role in preventing the extract from being oxidized. The product can be utilized by animals better.

Description

technical field [0001] The invention belongs to the field of feed additive processing, and in particular relates to a feed additive containing natural lutein and a preparation method thereof. Background technique [0002] Fish oil is a natural health food with high utilization value. The polyunsaturated fatty acids EPA and DHA contained in it have the functions of inhibiting platelet aggregation, antithrombotic, relaxing blood vessels, adjusting blood lipids, and improving biofilm fluidity. Cardiovascular disease, diabetes, dermatitis, colon ulcer and tumor suppression have good curative effect. Studies in recent years have also found that DHA has functions such as improving brain function, enhancing retinal reflexes, and preventing senile dementia. my country has a long coastline and rich fish oil resources. At present, the development and utilization of fish oil functional food in our country is still relatively small, and its development prospect is very broad. [0003...
