A METHOD FOR PRODUCING ANIMAL FOOD CONTAINING A COLOUR PIGMENT

摘要

A method for producing animal food which contains a colour pigment, wherein a colour pigment which has been produced by a microorganism is added to the animal food. A material which is rich in starch is used as a nutrient medium for the microorganism during the production of the colour pigment. Then the starch-rich material, insofar as it has not been consumed by the microorganism, is added to the animal food together with the pigment thus produced.
