Abstract

Annatto (Bixa orellana L.) seeds are the source of an orange yellowpigment. The water-soluble annatto dye formulations can be used in beverages, bakery and other food products. An annatto water-soluble dye formulation containing norbixin fraction 22.4 g/L was used in making an orange-ready-to-serve (RTS) beverage model with citric acid and sugar. The orange-RTS beverage was stored at ambient and refrigerated conditions in transparent as well as amber-coloured glass bottles for a period of 5 mo. A dilute solution of the annatto dye formulation (working stock) without addition of citric acid and sugar was also stored under similar conditions. The annatto water-soluble dye formulation and the orange-RTS beverage stored at refrigerated conditions stored well, whereas the losses were very high for the working stock of the formulation irrespective of the storage period/method.
