STUDY WITH THE VIEW TO DEVELOPING RATIONAL TECHNOLOGICAL PROCEDURES FOR THE PRODUCTION OF ESSENTIAL OIL FROM STAR ANISE FRUIT,

Abstract

Methods for the production of essential oil of the fruit of star anise by steam distillation were studied with the view to developing a satisfactory technological process. The effects of the degree of disintegration of the fruit on the yield of oil, the length of time of distillation, and the amount of steam used were determined. A procedure is proposed whereby steam distillation is first carried out at atmospheric pressure and than at a higher pressure (2--6 atm) or with superheated steam. (Author)
