Summary. Theoretical and experimental researches of extraction processes from plant origin raw materials: barley, acorns and chicory with liquid carbon dioxide, as well as lupin with cheese whey were carried out. Quality indicators of extracts and secondary raw materials are defined. It is established that they are perspective raw sources for the enriched and functional products as they contain amino acids, vitamins and microelements. The dairy-vegetative lupine extract, for example, contains 17 amino acids, including the essential as well as vitamins and minerals. The studies of secondary raw materials, barley, acorns, chicory and lupine quality showed the expediency of their use for foods enrichment. Quality indicators of secondary raw materials are presented in the tables form in the given work. It formed the basis for the development of hardware-technological schemes of obtaining СО2-extracts and their use. The hardware-technological scheme of obtaining СО2-extracts from barley, acorns and chicory includes a number of equipment units: motor transport for raw materials delivery to the enterprise, the scraper hydroconveyor, the jet washer, a photoseparator for of poor-quality raw materials and impurities removal, a blowing machine for removing surface moisture from the raw materials, a jet washer for peeling, a cutter, drying and frying device, a crusher, a roller machine tool and an extracting unit. Hardware providing for yoghurt technology enriched with amino acids, microelements and vitamins which are present in a dairy-plant extract differs from the mentioned above one in the following. The extract used is a cheese whey, and the extraction of a target component is carried out in a vibrating extractor. The hardwaretechnological scheme is made according to Russian technology of yoghurt and furnished with the equipment for dairy-vegetative extract feeding into a product. It includes the following: a vibrating extractor (not shown in fig. 2), the extract collector, the cover and tube heat exchanger and the refrigerator. Prerequisites reconditions are stated at a heat exchanger choice. The offered scheme can be used in the manufacture of other fermented milk products. Thus, the hardware-technological schemes developed by the authors contribute to the complex processing of secondary raw materials of plant origin which is economically and ecologically expedient.
