Abstract

The present invention discloses a liquid lutein and a preparation method. The method comprises the steps that: the lutein granular-crystalline is dissolved in water soluble organic solvent with a weight of two to five times; and the surface active agent and (or) the emulsifying agent with a weight ratio of 0.01 to 0.05 and the antioxidant with a weight ratio of 0.01 to 0.1 are added in the liquid; and then water is added to dissolve after fully and evenly mixing the liquid. The liquid lutein has the advantages of stable performance, which effectively increases the utilization rate and the absorption rate of the lutein with more remarkable coloring efficiency. Meanwhile, the method is characterized by easy manufacturing technique, high production cost and high yield rate.

Description

technical field [0001] The invention relates to the technical field of plant extraction and poultry feed colorant, more specifically relates to a liquid lutein, and also relates to a preparation method of the liquid lutein. The liquid lutein of the present invention can be granulated and then sprayed, which can solve the problem that the low stability of lutein itself limits its use. At the same time, liquid lutein can also be used in poultry farms. Adding in drinking water can effectively improve the utilization rate and absorption rate of lutein, and the coloring effect is more significant. Background technique [0002] With the improvement of people's coloring requirements for poultry products, the natural lutein contained in the feed raw materials (corn, corn gluten meal, alfalfa powder) often cannot meet the coloring requirements of the market; Commercial coloring agents are supplemented in the feed, and the quality of commercial coloring agents will have an important ...
