Abstract:
The practical application of carrageenan is largely determined by its physicochemical
properties, in particular rheological, which are different for different types of carrageenan.
Experimental studies have been conducted on the use of phytocolloid - carrageenan
Phyllophora (Zerniv deposit), extracted from the Black Sea red algae Phyllophora Brodyas.
Characteristics of carrageenan «PZF»: Moisture ₋ 11 %, mass fraction of ash ₋ 25.5 %.
The content of 3.6-anhydrogalactose is 21.3 %, the mass fraction of sulfoester groups (in terms
of SO4) is 24.2 %. . It has been established that carrageenan «PZF» solutions retain
their inherent anamnesis-viscous properties in a wide pH range. When the pH of solutions
changes from 4 to 10, no signs of conformational transition of carrageenan macromolecules are
detected.
