ABSTRACT:
The invention provides a cochineal color, a colorant product containing the cochineal color and the method of its production, wherein the cochineal color is free of allergenic proteins and contaminants derived from the raw materialCoccus cactiL. insect and can be added with safety to products taken by mouth, such as foods, pharmaceutical products, etc. The invention relates to a cochineal color substantially free of proteins of molecular weight not less than 6000. The invention also relates to a process for producing a cochineal color which comprises subjecting a cochineal extract solution to proteolysis and then to at least one treatment selected from the group consisting of adsorption treatment, ion exchange treatment, acid treatment, extraction treatment and membrane treatment.
