Abstract: A process for decaffeinating and aqueous coffee extract involves contacting the extract with a fatty solvent while concurrently vacuum distilling a portion of the water initially present from the aqueous coffee extract and subsequently separating the decaffeinated coffee extract and the caffeine-containing fatty solvent.

Abstract: Caffeine adsorbed on caffeine adsorbents is recovered by contacting the carbon with a solvent, preferably an aqueous solution of ethylene carbonate or propylene carbonate. The caffeine adsorbent is contacted with the solvent for a period time sufficient to remove at least a portion of the caffeine adsorbed thereon and then separated from caffeine-containing solvent. The caffeine may be recovered from the solvent by precipitation.

Abstract: A method of producing dehydrated rice flakes wherein dehydration of an aqueous slurry of substantially completely gelatinized rice starch granules and gelatinization and dehydration of a minor proportion of admixed ungelatinized rice starch granules is concurrently effected with a drum dryer. The dried sheet of substantially completely gelatinized rice material from the dryer is then subdivided into flakes or small platelets which require only the addition of hot water to quickly rehydrate to form a cooked rice product having the appearance and textural quality approaching that of freshly cooked mashed potatoes.
