摘要：

Water extracts of Hibiscus sabdariffa L. (Jamaica) calyces were foam-dehydrated. Combinations of two emulsifiers (Sorbac 60-Polydorbac 80) were used to study the stability of foams and their suitability for further dehydration. Maltodextrins (5 % w/w) were added as drying aids. The effects of temperature and sample thickness on dehydration rates were evaluated. Drying times were found to be proportional to power thickness. Results indicated that moisture transfer is externally controlled.
