The antiradical properties of hydrolysates and hydrothermal extracts of bivalve mollusks (Anadara broughtonii) from the Far Eastern Region of Russia and their influence on lipid oxidation in mayonnaise were investigated. The radical binding activity
Raman spectroscopy was used to investigate molecular interactions and the water binding structure in hydrated hydroxypropyl cellulose Klucel® Pharm HPC type MF. During the study, there were examined samples with water content equal to 0.69, 1.41 and
