Organic Edible Pigment Gardenia Extract Gardenic Blue and Gardenic Yellow
What is Gardenia Yellow?
Gardenia yellow pigment, with high quality gardenia fruits as the raw material, is expected by microwave-
assisted extraction in water, ultrafiltration (UF), nanofiltration (NF), refining and drying. The product is ofbright
golden yellow in aqueous solution, with strong tinting strength, and the main compositions - crocetin and
crocin - are water soluable natural carotenoids. Gardenia yellow, with strong acid and alkali resistance, and
the optimum PH value 3-10, has a wide application range, and good heat and light resistance. In addition to
iron ions, it is stable against metal ions.

What is Gardenia Blue?
It's a kind of blue powder, almost ordorless and tasteless; easily soluble in water, hydrous ethanol and aqueous propylene glycol; bright - blue in color. There is no change in tonality when PH values 3 - 8; heat - resistant and the color does not fade at 120℃ for 60min. It has weak hygroscopicity and light resistance, but strong dyeing powder against protein, with absorbance (1000 times dilutes aqueous solution, 590nm) of 0.5. Technological process; take geniposide - a chemical composition in Rubiaceae plant - gardenia as the raw material, and obtain genipin by stripping of glucosyl group at the end of geniposide molecular under the effect of β-1, 4- glucosidase (EC 18.104.22.168). Then, through a series of polymerization and rearrangement reaction between genipin and amino acid, gardenia blue pigment can be derived after final drying. The flow is as follows: Cellulase → Enzyme solutions →Geniposide enzymolysis →Genipin →Amino acid polymerization →Gardenia blue pipgment solution →Ultrafiltration (UF) →Freeze drying →Gardenia blue pigment powder.
