Embodiment Construction

[0008] Below in conjunction with embodiment the present invention is further described.

[0009] In order to realize the object of the present invention, the technical scheme of the present invention is: a kind of processing method of natural plant feed coloring agent, and feed coloring agent comprises: leaf powder, vitamin C, citric acid; Feed coloring agent formula: press leaf powder: vitamin C : citric acid mass percent is 95-99.8: 2.5-0.01: 2.5-0.01 mixing; Feed coloring agent production process is: picking the mature leaves of okra whose lutein and β-carotene content are all more than 300mg / kg, drum at 4 ℃ low temperature Air-dried to water content below 3%, the mature leaves of okra are crushed into yellow-green powder and cross 100 mesh sieves, and the leaf powder: vitamin C: citric acid mass percentage is 95-99.8: 2.5-0.01: 2.5-0.01 and mixed in Store in an environment with a sealed light-shielding room temperature of 2-10 ° C and a humidity of 40%. When in use, add w...

Abstract

The invention discloses a method for processing a natural plant feed coloring agent. The manufacturing process of the feed coloring agent comprises the following steps of: picking okra mature leaves with the content of lutein and beta-carotene of both over 300mg/kg; crushing the okra mature leaves into yellow green powder, and sieving with a 100-mesh sieve; mixing the yellow green powder, vitamin C and citric acid in a mass ratio of 95-99.8:2.5-0.01:2.5-0.01; and preserving the mixture in a sealed and shaded environment with a humidity of 40 percent and at the room temperature of 2 to 10 DEG C. A plant having high color material content, a good nutrition constituent, a high coloring speed, an obvious coloring effect, a simple acquisition way and a low processing cost is screened from a large number of plant resources, is processed into the natural plant feed coloring agent which has a good coloring effect on skins, fats and yolks of poultry after being processed, belongs to a purely natural green product, ensures the safety and quality of foods and has a good utilization and development prospect as the feed coloring agent for the poultry.

Description

technical field [0001] The invention belongs to the technical field of color additives for poultry and aquaculture animal products, and in particular relates to a processing method of a natural plant feed colorant. Background technique [0002] At present, colorants are an important part of feed additives and have been used in the feed industry for nearly 40 years. Its status and role are more and more reflected in today's fast-growing feed industry, and its effectiveness has been widely recognized by the world. It is a class of additives that enhance the color of poultry and aquaculture animal products. It can be transformed and metabolized in animals, but cannot be synthesized in the body and must be ingested from feed. Many studies have shown that carotenoids and their derivatives are mainly responsible for the coloring of poultry products, namely lutein, β-carotene, marigold extract (natural lutein), capsanthin, β-apo- δ'-carotene aldehyde, β-apo-δ'-carotene ethyl est...
