EXPERIENCE OF HIGH PRESSURE PROCESSING IN THE FOOD INDUSTRY
Recently, there has been an increase in the consumption of products in which there are no preservatives. This fact is associated with the consumer's awareness of the negative impact of non -natural components on the human body. Therefore, one of the priorities in the food industry is the development of recipes of products consisting of natural components. Research in the field of high-pressure processing of food products of animal origin only today are carried out by both Russian and foreign scientists. Based on the experience of scientists, the application of this process in the field of high-pressure processing of plant products is proposed. The object of research presented in this article are the developed models of mixtures of vegetable raw materials for the prepar ation of hot non-alcoholic beverages based on narrow-leaved boiling water. It is known that medicinal and tec hnical raw materials are the source of biologically active substances that have a synergistic effect on the human body. The article presents the results of experimental studies to i dentify the parameters of high-pressure treatment of research objects. The basis for determining the parameters of processing was taken by the experience of can adian scientists, indicating that the range of applied pressure should be between 100 MPa and 20 0 MPa, and the processing time of 60 and 90 C. Determination of the optimal parameters for the samples was based on the results of the content of biologically active substances (vitamin C, bioflavonoids) and antioxidant activity of control and processed models. The article presents the results allow to identify that the optimal parameters were: 150 MPa for 90 s; 200 MPa for 60s. These parameters influence of high pressure lead to the destruction of molecules and inte r-cellular tissue, which has a positive effect on the extraction of biologically active substances in the extract of the mixture models of vegetable raw materials for making of hot non -alcoholic beverages series «Fireweed».
