Thermally accelerated short time evaporation

Today, multistage vacuum evaporation is the predominant method used for liquid food concentrahon. Its major drawback is that it causes heat-induced deterioration of sensory (color, taste, and aroma) and nutritional (vitamins, etc.) value of the hnished product. The food industry has developed alternate methods, such as freeze concentration and thermally accelerated short time evaporation (TASTE) [20] for recovery and blending of such labile constiments for producing concentrates. Though they are currently practiced commercially, the final products in some cases do not satisfy the consumer requirement of their fresh or natural qualities. Some of these processes are energy intensive and therefore unattractive.
