The structural and mechanical properties of concentrated emulsion on the basis of protein-lipidic mixtures

Rheological properties of the concentrated oil/water emulsions have been investigated by the method the of rotation viscometry. Heptane has been used as an oil phase. The experimental data have been described with the help of the rheological models of Kasson and Gershel-Balckly. It has been proved that emulsions have properties of plastic body. The lecithin concentration increase diminishes the limit of fluidity and viscosity of emulsions. The decrease of the concentrated emulsion structure strength is connected to the lyophilization of systems at lecithin presence.

Non-waste technology of marine Crustacea testa processing

The industrial process of chitin extraction of Crustacea testa is connected with the formation of specific fluid wastes containing a great amount of protein compounds and mineral substances. The opportunity of protein compounds' precipitation out of technological discharges has been studied. The schematic circuit of sewage two-stage treating of chitin production has been proposed.
