SUMMARY
—A study has been made of volatiles retention during the drying of aqueous solutions, by putting droplets, fixed on a wire, in an air current. The droplets were of an aqueous solution of malto-dextrin, to which small amounts of acetone had been added. Radioactive labeling permitted quick and accurate measurements of the acetone concentration in a drying droplet. During drying, a film forms on the surface of the droplet. The higher the initial carbohydrate concentration, the quicker the film forms. This film is permeable to water, but impermeable to acetone and to other volatile compounds, such as benzene, ethanol, and ethyl acetate. No satisfactory explanation for the retention can be given. In any case, adsorption is not involved.read more

Retention of Aroma Compounds by Carbohydrates: Influence of Their Physicochemical Characteristics and of Their Physical State. A Review
TL;DR: In this article, the influence of physicochemical properties of both the volatiles and the carriers on retention is discussed, and the effect of these properties on the diffusion of the aroma compound through the matrix and on the ability of the volatile to form small drops.

TL;DR: In this article, a qualitative and semi-quantitative examination of industrial and pilot plant spray-dried materials was carried out to identify structural and morphological features, and three distinct categories of particle morphology were identified, namely, crystalline, skin-forming and agglomerate.

Correction for Quenching Associated with Liquid Scintillation Counting
G. A. Bruno,J. E. Christian +1 more
TL;DR: In this paper, a simple procedure is described for correcting counting errors due to quenching in small-volume liquid scintillation detection methods, which is only valid for higher activities and does not appear to be appropriate for routine counting operations.
