Production process of feed-grade liquid-state natural lutein product

Abstract

The invention relates to a production process of a feed-grade liquid-state natural lutein product. The production process includes specific production steps: preparing natural lutein extract saponification liquid and emulsification powder, adding the emulsification powder into the natural lutein extraction saponification liquid, and stirring. The product is safe, healthy, long in emulsification stable quality guarantee period, low and economical in production cost, convenient and flexible to use and operate and outstanding and efficient in coloring effect, and the production process is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of production of feed additive products, and in particular relates to a production process of feed-grade liquid natural lutein products. [0002] technical background [0003] As a pure natural plant extract pigment, natural lutein can not only color, but also resist oxidation, and has the characteristics of safety and health. Therefore, it has been widely used in animal breeding. [0004] At present, natural lutein is used as a feed additive, and it is mainly used in feed in the form of solid powder. It is usually added in the mixing process of feed raw materials, and then it is prepared by conditioning, extruding, drying and other processes along with other raw materials. However, due to the influence of high temperature and high pressure during feed granulation, natural lutein will be greatly lost, resulting in increased use costs and waste of pigment resources. However, liquid natural lutein products ha...

Problems solved by technology

Although there are already many patents on the saponification process of natural lutein extract in the field of feed additives, there are basically two problems: the first is that the loss rate of lutein is relatively large and the saponification time is relatively long, which takes 4 to 8 hours, which is extremely difficult. The land restricts industrial production capacity, which is not conducive to large-scale industrial production; the second is that the use of auxiliary reagents is more diverse and used in large quantities, especially the selection of low-boiling point alcohols, resulting in high equipment investment, complicated process operations, and even waste of resources and Environmental pollution and other issues

[0006] Chinese Patent Publication No. CN104431303A discloses "a liquid lutein feed additive and its preparation process". The saponification process of the natural lutein extract involved is time-consuming and energy-consuming, the amount of auxiliary reagents is large, and ethanol is volatile. Recycling and collection devices are used, so the equipment investment is high and the operation is more complicated, otherwise it will easily cause resource waste and environmental pollution, and this process cools the saponified lutein saponification liquid prepared by saponification into solid saponified lutein extract before proceeding use, resulting in the need to use additional equipment for storage and heating to melt the saponified lutein extract, resulting in a great waste of energy; in addition, the preparation process of the emulsion requires a large amount of water to heat and dissolve a large amount of emulsifier, which is extremely time-consuming and energy-consuming.
