Embodiment 1

[0034] (1) Oil extraction to extract lutein and nutrients

[0035] 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.

[0036] (2) Separation of extract

[0037] 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 ...

Embodiment 2

[0047] (1) Oil extraction to extract lutein and nutrients

[0048] Put 25 parts of soybean oil into a steam pot, slowly add 15 parts of marigold petal powder, stir while heating, stop heating after raising the temperature to 90°C, keep warm and stir for 4 hours, and then stop heating to obtain an extract; , the marigold petal powder is prepared by the following method: freshly picked marigolds are removed from flower stem buds, the petals are air-dried for 8-10 hours, and crushed through a 100-mesh sieve.

[0049] (2) Separation of extract

[0050] 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 extraction oil;

Abstract

The present invention discloses a nature lutein-containing feed additive, which is prepared by emulsifying a water phase and an oil phase according to a weight part ratio of the oil phase to the water phase of 2.8-3.5:7, wherein the water phase is prepared by mixing deionized water and disodium hydrogen phosphate according to a weight volume ratio of the disodium hydrogen phosphate to the deionized water 1 g:650-750 L, the oil phase is prepared by mixing extraction oil, Tween 80 and monoglyceride according to a weight part ratio of the extraction to the Tween 80 to the monoglyceride of 38-42:7-11:10-14, and the extraction oil is prepared from the following raw materials by weight: 15-25 parts of fish oil or vegetable oil, and 8-15 parts of tagetes erecta l petal powder. According to the present invention, the fish oil or vegetable oil is adopted as the tagetes erecta l extract carrier, such that the effective components of the tagetes erecta l can be completely extracted, the extract can be protected from oxidation, and the product can be well 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. 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] Marigold i...
