AB  - Preparation of alginate-soy protein isolate (AL/SPI) complex beads containing essential oil of thyme was carried out by emulsification of thyme oil in aqueous sodium alginate solution blended with SPI solution, followed by atomization via electrostatic extrusion and gelification with calcium ions. The process parameters were optimized by variation of the alginate (1-2.5 wt.%) and SPI (0-1.5 wt.%) concentrations. Dry alginate-SPI particles exhibited wrinkle surface while shape distortion of hydrogel beads occurred with  gt = 1.5 wt.% alginate concentration, whereas SPI induced reduction of the particle size. Encapsulation efficiency of 72-80 % based on total polyphenols was achieved. In SGF the samples exhibited oil release of 42-55 % (due to matrix shrinkage and proteins degradation by pepsin activity), while the rest was delivered in SIF within 2.5 h simultaneously with swelling and degradation of the matrix.

AB  - The influence of concentration and temperature on the rheological properties of tomato pomace dispersions obtained by rehydration of lyophilized and grinded tomato pomace was investigated in this paper. Examined systems comprised of different lyophilized tomato pomace concentrations (18.2, 16.7, 14.3, 12.5, 11.1, 10.0, and 9.1%) heat treated at two different temperatures (60 degrees C and 100 degrees C) during 30 min. According to microstructure analysis of the studied system, it could be simplified as the composite consisting of insoluble particles surrounded by the pectin network. The system behaves as viscoelastic solid (G'  gt  G '' at all angular velocities), and therefore the static modulus of elasticity, the effective modulus and the damping coefficient were determined by application of modified fractional Kelvin-Voigt model. The influence of particle concentration on the rheological properties of tomato pomace system is dominant in comparison to the content and composition of pectin solubilised in the serum. Concentrated tomato pomace dispersions are much stiffer (G' values an order of magnitude higher) than the composite systems. Heat treatment at higher temperature (100 degrees C) decreases the stiffness of the system by breaking of non-covalent bonds between dispersed tomato particles and surrounding pectin network. Storage modulus as a function of the tomato pomace lyophilizate concentration was considered within three regimes (regime 1 - concentration  lt 11.1%; regime 2 - concentration 11.1%-16.7%; regime 3 - concentration  gt  16.7%) that could be used as the base for formulation of tomato pomace-based products with different desirable consistencies, such as sauce, ketchup and marmalade.
