Investigation on isolation and purifying of gardenia blue pigment with D301 ion exchange resin;

Study on the production and purification of gardenia blue pigment with high colour value

The fermentation conditions of Gardenia blue pigment were studied by single factor changed and orthogonal design The optimal conditions were obtained though optimizing under the optimal conditions,the yield of Gardenia blue pigment was improved 2 4 times compared with unoptimizatio

The culture liquid was hydrolyzed and filtrated, and reacted with glutamic acid, and Gardenia blue was made, the conversion rate is 98.

This paper reported the effect of pH, temperature, oxidizer, light, metal ion, food additives on the stability of gardenia blue and its application in foods, cosmetics, medicines and other products.
