Persimmon fruits are dietary food products with a high proportion of biologically active compounds and a wide range of trace elements and vitamin complexes, as well as polysaccharides and dietary fibers. However, the preservation of harvested fruits is a problem due to complexity and high costs. For this reason, the modern approach implementation to the processing of raw materials of plant origin and the production of food materials based on it enable to preserve the beneficial characteristics of persimmon fruits, significantly. A man run the extraction intensification on the basis of information about its statics, kinetics and hydrodynamics. The study aimed at determining the kinetic patterns and specific yield of water-soluble substances from the persimmon pulp based on the rational ratio determination of the extractant and the extraction object (hydromodule). The authors indicated the rational hydromodule in the mass transfer process during the experimental series, where the target function was the highest specific yield of the target components. There were two versions of the kinetic pattern study of the extraction process: with and without ultrasound. The study results revealed the kinetic patterns and determined the specific yield of water-soluble substances from persimmon pulp on the basis of a rational hydromodule. The resulting form of the mass transfer intensity curve is typical with certain specifics for such materials and extraction methods defining the distribution coefficient value, the component extraction selectivity of the persimmon fruit pulp, as well as the conditions for extraction, which determine its mechanism. All this indicates the utility of the traditional extraction method improvement, in particular, when using ultrasound.
