Higroscopicity of milled rosemary (Rosmarinus offlcinalis L.)

Abstract

The adsorption isotherm of a sample of milled rosemary with microbiological good quality and humidity content of 13,6% db was determined. The adsorption data experimentally obtained was fitted to model proposed by G.A.B. The monolayer humidity calculated throw this model was 1,52%. The milled rosemary evaluated sensory and microbiological at the equilibrium was accepted until a relative equilibrium humidity of 67,9% and the humidity content was 7,09% db.
