摘要
The present invention relates to a process for the preparation of bixin dye from annatto (Bixa orellana L) seeds. Annatto extracts obtained from the seeds of the tropical shrub Bixa orellana L. have wide spread use in the food industry for the colouring of many commodities. The principal colouring component of annatto seeds is the liposoluble diapocarotenoid 9'-cis-bixin, which is the monomethyl ester of the water soluble 9'-cis-norbixin. Annatto extracts are usually formulated to provide suitably stabilized forms in the colour range red-orange-yellow for use in a wide range of foods such as dairy products, flour confectionary, fish, soft drinks, meat products, snack foods, and dry mixes.
