Embodiment 1

[0036] (1) Oil extraction to extract lutein and nutrients

[0037] 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: freshly picked marigolds remove flower stem buds, air-dry the petals for 8-10 hours, and crush them through a 100-mesh sieve.

[0038] (2) Separation of the extract

[0039] Store the extract obtained in step (1) for 24 hours and then divide it into upper and lower layers. First extract the supernatant, then pass the product from the lower layer through a 300-mesh sieve, press and filter, and the obtained filtrate is the same as the obtained The above supernatants are mixed to obtain extraction oil;

Abstract

The invention discloses a feed additive containing natural lutein. The feed additive is prepared by the following step: carrying out emulsification on a water phase and an oil phase according to the weight part ratio of (2.8-3.5):7, wherein the water phase is prepared by mixing deionized water and sodium hydrogen phosphate, and the weight volume ratio of the sodium hydrogen phosphate to the deionized water is 1g to (650L-750L); the oil phase is prepared by mixing extraction oil, Tween 80 and monostearin, and the weight part ratio of the extraction oil to the Tween 80 to the monostearin is (38-42):(7-11):(10-14); the extraction oil is prepared from the following raw materials in parts by weight: 15-25 parts of fish oil or plant oil and 8-15 parts of marigold petal powder. With the adoption of a preparation method of the feed additive, with the fish oil or the plant oil as a carrier of a marigold extract, the active components of marigold can be fully extracted, and the extract is protected from oxidizing. The feed additive can be better utilized by animals.

Description

technical field [0001] The invention belongs to the field of feed additive processing, in particular to a feed additive containing natural lutein and a preparation method thereof. [0002] Background technique [0003] 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. [0004] ...
