Contemporary studies in the field of dietary fibers isolation from sugar beet pulp

Sugar beet pulp is a promising source for obtaining pectin, protopectin, cellulose, hemicelluloses and lignin. The article gives a brief description of the most common technology for producing pectin from sugar beet pulp, as well as the results of domestic and foreign studies aimed at improving the finished product yield and quality. It has been established that pulp drying regimes have a decisive influence on the quality of the obtained pectin, predetermining its structural properties. With a decrease in pulp particle size for extraction, pectin yield increases by 20 % with a concomitant increase in galacturonic acid content by 60%, however, its rheological properties deteriorate. Electrochemical treatment of extractant for pectin obtaining increases pectin yield by 18-20 %, while electric treatment of the beet pulp by 50 %. The scientific works aimed at obtaining RG-1 «hairy» pectin, as well as the pectin fermentation in order to produce oligosaccharides with the best prebiotic properties have been considered. The results of the studies aimed at chemical obtaining of 10-70 nm cellulose nanotubes in pure form from depectinated pulp, as well as cellulose nanotubes in the composition of gels from fermented beet pulp, have been presented. The work aimed at the use of dried beet pulp as lignin-containing raw materials in chipboards production has been described
