Abstract:A edible red pigment was extracted from the fruit of Hylocereus Costaricensis (Weber) Britt for the first time.A study was conducted to exam technological conditions of extracting the red pigment,including selection of soaker and soaking dose,the effect of soaking temperature,pH and soaing time on extracting rate.The results showed that the pigment is soluble in water and the suitable soaker is the ethanol aqueous solution of 70%,and that the extraction should be undertaken by two time of solvent at room temperature for five hours.
Keywords:Hylocereus Costaricensis  (Weber)Britt    pigment  extraction  technological condition
