Iinfluence of Main Technological Parameters of Drying on Quality of Bagasse From Carrot and Beet

The work studies the drying process of vegetable bagasse, namely of carrot and beet. There is studied the moisture content kinetics of vegetable bagasse and determined the dependence of the process duration on main technological parameters in the work of a vibration vacuum dryer, namely, an amplitude and frequency. There were studied quality parameters of obtained concentrated products, namely the colorimetric estimation of dried bagasse of carrot and beet. Based on obtained results of the study, it was established, that the use of vibration in the process of drying bagasse favors conservation and formation of colorimetric characteristics of a dried product. Determined color characteristics gave a possibility to establish, that at thermal processing it is very important to decrease the drying process duration and temperature. Research data proved prospects of producing concentrated products, namely, dried bagasse of carrot and beet by the offered method. It allows to regulate quality parameters of a ready product: color, brightness, consistence, viscosity and physical-chemical properties. Obtained concentrated products are characterized with high organoleptic indices, food value. This product may be used in the wide spectrum of food industry, such as, for example: juice supplement, stuff for confectionary mass, filling for confectionary products, as biological supplement for healthy nutrition

Devising Manufacturing Techniques for Making Culinary Meals Using Vegetable Concentrates

It is known that the vegetable concentrates' composition includes dietary fibers, micro-elements, color-forming substances, which can be successfully used as a substitute for the main substance in a formulation. This paper reports the development of a technique to process vegetables into vegetable semi-finished products, the formulations of culinary meals based on vegetable concentrates, as well as the techniques of their heat treatment using electrocontact heating (ECH).A technique to process vegetables into vegetable semi-finished products using carrot as an example implies the separation of raw materials into juice and pomace followed by separate processing of each component. Depending on the technological tasks, it is possible to obtain a vegetable concentrate by mixing juice and dried pomace. The colorimetric quality assessment has helped establish the parameters for juice and pomace processing. A carrot-based concentrate has been studied in terms of the content of the dried pomace. It was established that adding it improves the quality of the product, namely the brightness and color purity become better.It has been proposed to use carrot pomace in the formulations for different culinary meals provided the heat treatment process is intensified by combining convective heating and ECH. Carrot pomace was used in formulations for several culinary meals (rice pudding, millet balls, as well as unleavened pastry).The combined thermal treatment of experimental products involving ECH provided several advantages in terms of the technological indicators, namely: the duration of heat treatment decreases by 20...40 %, the output increases by 10...20 %, and energy consumption decreases by 23...32 %, which is an argument for its application.Based on the organoleptic assessment, it was noted that, in addition to the taste inherent in these products, the resulting products acquired a kind of pleasant taste of carrot, the increased juiciness and tenderness, which can attract the consume
