Modern technologies, especially drying processes, are energy consuming. Also, the main tasks in the development of heat technology in the food industry is to reduce energy costs for the dehydration process. Such scientific developments will make it possible to increase the level of energy security of the state and the competitiveness of the national economy, to reduce Ukraine's dependence on imported energy in general. Due to the spread of diseases such as cardiovascular disease, cancer, changes in heart muscle, poor digestion, impaired reproductive function, the main task of food industry workers is to replace as much as possible in the finished food synthetic flavors, dyes for natural. Today in Ukraine there is not enough production of vegetable raw materials in powders that allow to preserve the quality of raw materials. Modern methods of obtaining red beetroot powder make it possible to keep betanine at the level of 50-70% in the final product. Therefore, the development of new methods and improvement of existing technologies for drying red beetroot in order to obtain a natural dye is important and significant. The main raw material, that has a high content of betanine with antioxidant properties is red beetroot. This culture is traditional in the diet of the population of Ukraine. An important emphasis in the processing method of drying antioxidant raw materials is to reduce energy consumption for the dehydration process, the maximum preservation of biologically active substances and reduce the cost of the final product. The benefit of natural antioxidants is that they are able to react with free radicals, neutralizing their harmful effects on the human body. Red beetroot is one of the few crops that contains betanine - a product of enzymatic decomposition of choline, which plays an important role in metabolism in the human body. This article presents waste-free energy-efficient heat technology for antioxidant red beetroot-tomato dye and tomato seeds. Thanks to the use of tomato pulp and peel as a natural stabilizer of betanine and two-stage convective drying, we obtain high-quality seed material and powdered natural product, which due to the high content of carotenoids, pectins, fiber, betanine, micro- and microelements can be used in therapeutic and prophylactic balanced diet. Red beet-tomato antioxidant dye improves the structure and consistency of products, gives color to products, increases their biological and nutritional value and can be widely used in the production of therapeutic and prophylactic purposes.
