[Acid-base and ion-exchange properties of dietary fibers]. / Kislotno-osnovnye i ionoobmennye svoistva pishchevykh volokon.

Acidic-basic characteristics of ionogenic groups of dietary fibers (DF) isolated from various raw materials were determined by potentiometric titration of DF using a method of individual weights and the ion-exchange properties of DF were estimated. The cation-exchanging ability of DF is within the range 0.2-1.5 meq/g DF. The calculated apparent constants of the acidic-basic dissociation of the DF functional groups are within the range allowing their reference to weakly acidic and basic groups. The source of the former can be polysaccharides (pectin substances, hemicelluloses), lignin and the protein accompanying DF components, which being an ampholyte possesses also basic properties. The effect of DF preparation on acidity of the gastric juice was studied to elucidate a possibility of using concentrated DF preparations for the correction of the states resulted from the hypersecretion of hydrochloric acid by the mucous membrane of stomach.

[Food fibers as modifiers of homeostasis in patients with diabetes mellitus]. / Pischevye volokna kak modifikatory gomeostaza u bol'nykh sakharnym diabetom.

The addition of 7 g of fodder grass food fibers to the ration of 61 patients with diabetes mellitus 3 times a day resulted in a decrease in fasting hyperglycemia, reduced hyperlipoproteinemic shifts and induced a fall in the hemocoagulation potential in 3 weeks.
