Abstract
One of the promising directions of improving the processes of processing plant raw materials is bioconversion using enzyme preparations, the use of which allows you to significantly change, intensify and improve existing technologies for the production of food products as a system of energy-efficient processes. The subject of the study is the enzyme preparation of inulinase Bacillus polymyxa 29, which ensures the conversion of the plant polymer inulin to fructose. Fructose has an increased interest in food technologies as a safer human health alternative to sucrose. Fructose yield reaches 90–95%; the sweetness coefficient of fructose is 1.73 times higher than sucrose. Production of enzyme with maximum activity is achieved by vacuum-sublimation drying at time-programmed mode of heat supply control taking into account limitations due to quality of heat exchange and economic feasibility of the process. Method of selection of optimal solutions in vacuum-sublimation drying of feather preparation Bacillus polymyxa 29 according to profit index is proposed. The proposed approach resolved the main technical gap between productivity and energy consumption. An optimal loading of the sublimator has been established, which ensures the minimization of specific electric power consumption for various values of the initial moisture drying of the enzyme, taking into account the given efficiency of the vacuum sublimation dryer.
