Possibilities of the gases analyzer "electronic nose" (EN) were estimated when forecasting influence of functional preparations on protein systems odor. Sorption of volatile organic compounds that create the odor of meat products was studied on thin films of sorbents - modifiers of piezoelectric resonators' electrodes forming an array of sensors of EN. The obtained sensor array is trained on t ...

A process of producing an agglomerated structure powders by spray drying of liquid food and chemical environments is described. The development of this direction is the method based on collision in the cyclone chamber of dispersible liquid particles and swirling stream of previously dried ones, returned from the separation system of fine fraction from spent heat medium. Thus, the solid particl ...

A method of synthesizing the mathematical model of the process of dairy products homogenization is presented. The basis of the mathematical model is Markov's chain with discrete states and continuous parameter which the homogenisation pressure was taken for. To describe the processes of adhesion of fat globules during homogenisation process when there is a large percentage of fat and homogeniz ...

Variant of solving problem of biomass selection optimal control from apparatus using Pontryagin maximum principle is presented. Device's maximum productivity was chosen as optimality criterion. On a finite-dimensional space the Pontryagin function, the Hamiltonian function, and the end function were defined. To describe the dynamics of the development of the yeast population, the Ferhulst-Gaus ...
