Kind Code:
A1
Abstract:
Provided is a method for producing a natural red pigment, particularly a plant-based red pigment. The method involves producing a red pigment by reacting a protein hydrolysis product with an iridoid compound having a carboxyl group at position 4 of an iridoid skeleton. The protein hydrolysis product has an amino acid content of at least 35 wt% in terms of the protein hydrolysis product dry weight, and according to ninhydrin assay, at least 50 wt% of the amino acid is glutamic acid and aspartic acid and the ratio of the leucine weight to the total weight of the glutamic acid and aspartic acid is no greater than 8 wt%. It is also possible to react the protein hydrolysis product and taurine or a taurine-containing substance with the iridoid compound.
