Abstract

The invention provides a production process of phytoxanthin feed additive. The process comprises the following steps: preparing potassium hydroxide liquid; adding the potassium hydroxide liquid to cymbopogon citrat extract with a certain temperature according to proportion; adding propylene glycol and ethoxyquin in turn while stirring; raising the temperature and saponifying to obtain the saponification liquid; adding silica powder to the saponification liquid, and then stirring; finally screening to obtain the phytoxanthin feed additive. The production process has the advantages of high yield of products, low industrial production toxicity and high safety, and is convenient to industrial production on large scales; at the same time, the products prepared according to the method has little residual methanol and good quality, and meets the regulations of national standard GB/T212517-2008.

Description

technical field [0001] The invention belongs to the technical field of biochemistry, and relates to a process for producing poultry feed additives with lutein extracted from calendula, in particular to a process for producing lutein feed additives. Background technique [0002] Lutein is a natural carotenoid widely found in vegetables, flowers, fruits and some algae. The natural lutein contained in plants is an excellent antioxidant that can prevent cells from being oxidized. Adding a certain amount of lutein to food can prevent a series of diseases caused by organ aging. Lutein can also be added to chicken feed as a natural pigment to improve the color of egg yolk and chicken skin. Free lutein can be directly absorbed and utilized by humans and birds, while lutein in the form of lutein esters is not easily absorbed by humans and animals. Therefore, extracting and separating free lutein has become one of the research focuses. Calendula is currently known to have the high...
