Abstract: The present invention is directed to a process for fixing or entrapping a fixable agent, such as acetaldehyde, in a carrier matrix, such as starch hydrolysates having a dextrose equivalent of not greater than about 28, to impart a stable, free flowing particulate configuration to the carrier-fixed agent. The process is achieved by impinging aqueous droplets containing the fixable agent onto particles of the carrier material in a manner which causes dissolution of the carrier particles into the droplets to form a saturated solution of the carrier in the droplet. A film then forms on the surface of the saturated droplet solutions by preferential evaporation of the water therefrom. This causes the droplets to set to a permanently particulate form thereby entrapping the fixable agent.
