The process of concentrating vegetable juice in an improved vacuum evaporator with a stirrer which is simultaneously a heat exchanger was studied. The process of drying carrot cake in the developed vibratory vacuum dryer was studied.
Dependence of content of beta-carotene on operating parameters of the dryer, namely amplitude and frequency was determined. Based on the obtained results of the study of colorimetric characteristics, it was proved that the proposed method for production of concentrates contributes to preservation and formation of colorimetric characteristics of the final product.
It was found that technological processing affects objective colorimetric characteristics of plant materials, namely, deviation of values of the dominant wavelength, color purity and brightness from the values for the reference sample.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.
