- Abstract
In this paper, we consider mechanical stress resistance of quercetin -- 3, 3', 4', 5, 7- pentahydroxyflavone in pure substance, in a mixture of crystalline solid quercetin with plant based polymers, and adsorbed on plant based polymers. The plant based polymers were produced by step-by-step chemical removal of components of plant material. The most stable to machine treatment is the quercetin adsorbed on cellulose polymer components, which retain the texture of the original plant tissue. The capability to increase quercetin stability in the process of mechanical treatment changes from hemicellulose via amorphous cellulose to crystalline cellulose. Adsorption on crystalline and amorphous cellulose, which do not retain morphology of plant material, causes reduction in the stability of adsorbed quercetin to a subsequent mechanical treatment. Quercetin that is adsorbed on polyphenolic plant based polymer lignin is the least resistant to mechanical treatment. The understanding of interaction of quercetin and other phenolic compounds with cellulose based matrixes can help to get a new view on technological processes of extraction and mechanical treatment of plant materials.
