The paper presents a comparative study of the content and composition biologically active substances aboveground parts plants some Monarda species cultivated in Botanical Garden, Ural Branch Russian Academy Sciences, Ekaterinburg. greatest quantity flavones, tannins were found M. citriodora Cerv. ex Lag., carotenoids, pectins, saponins fistulosa L., pectins didyma protopectins media Will. compo...

Maturation of potato (Solanum tuberosum L.) tuber native and wound periderm and development of resistance to periderm abrasion were investigated utilizing cytological and histochemical techniques. Both native and wound periderm consist of three different tissues: phellem, phellogen and phelloderm. It was previously determined that the phellogen walls of immature native periderm are thin and pro...

Plant polysaccharides include pectins, which are responsible for an important role in plant physiology and part of the cell wall. These compounds known as gelling stabilizing agents, widely used food industry. The scientific literature lacks precise information on spectroscopy apple pectin citrus pectin. Therefore, aim this work was to test compare physicochemical properties these compounds. cu...

As interest increases for colonic health, various studies have been conducted to investigate functional ingredients for host health and prevention of chronic disease in humans such as colon cancer and Type 2 diabetes. In particular dietary fiber has been reported to have beneficial effects on colonic health. More recently, dietary fiber has been categorized based on its characteristics and nume...

The apical wall of growing pollen tubes must be strong enough to withstand the internal turgor pressure, but plastic enough to allow the incorporation of new membrane and cell wall material to support polarized tip growth. These essential rheological properties appear to be controlled by pectins, which constitute the principal component of the apical cell wall. Pectins are secreted as methylest...

Strawberry softening is characterized by an increase in the solubilization and depolymerization of pectins from cell walls. Galactose release from pectin side chains by β-galactosidase enzymes has been proposed as one reason for the increase in soluble pectins. A putative β-galactosidase gene, FaβGal4, has been identified using a custom-made oligonucleotide-based strawberry microarray platform....

pectin is used as gelatinizing agent in food industry. in this study pectin was extracted from five commercial sugar beet varieties namely: doroty, rasul, 7112, br1 and ic using pre-hydrolysis technique. experiments were conducted using factorial design to verify the effect of temperature, time, percentage of hcl and water requirements on the extraction rate of pectin. the qualitative factors o...

Currently, pectins are widely used in the cosmetic, pharmaceutical, and food industries, mainly as texturizing, emulsifying, stabilizing, gelling agents. Pectins polysaccharides composed of a large linear segment ?-(1,4) linked d-galactopyranosyluronic acids interrupted by ?-(1,2)-linked l-rhamnoses ramified short chains neutral hexoses pentoses. The characteristics applications strongly influe...

BACKGROUND One of the main factors that reduce fruit quality and lead to economically important losses is oversoftening. Textural changes during fruit ripening are mainly due to the dissolution of the middle lamella, the reduction of cell-to-cell adhesion and the weakening of parenchyma cell walls as a result of the action of cell wall modifying enzymes. Pectins, major components of fruit cell ...
