Binding of aromaforming cryo- and thermotropic jellies of gelatin and starch

The regularities of binding substances of aromaforming cryo- and thermotropic jellies of gelatin and starch were studied. The influence of the surface of hydrophobic jelly on their ability to absorb aqueous solutions of thymol was experimentally confirmed. The reduction of sorption by thymol cryotropic jellies versus the thermotropic one was established. Experimentally it was confirmed that the most promising technology to create flavors from aromatic hydrophobic substances are thermotropic jellies y of gelatin with high hydrophobicity.

Mutual activation and sorption ability of rare cross-linked networks in intergel system based on polymethacrylic acid and poly-4-vinylpyridine hydrogels in relation to lanthanum ions

Sorption ability of intergel system polymethacrylic acid hydrogel (gPMAA) – poly-4-vinylpyridine hydrogel (gP4VP) in relation to lanthanum ions is studied. Hydrogels mutual activation in an aqueous medium, particularly dependencies of swelling coefficient, specific electric conductivity and pH of water solutions are studied. Maximum activation of hydrogels occurs at gPMAA:gP4VP molar ratio 3:3. Maximum total binding degree of polymer chain in the intergel system is observed at the ratio gPMAA:gP4VP = 1:5.
