METHOD FOR MANUFACTURING DRY PECTIN CONCENTRATE OUT OF BEET BAGASSE Russian patent published in 2005 - IPC

FIELD: food industry.

SUBSTANCE: the present innovation deals with hydrolysis of beet bagasse with hydrogen peroxide solution, extraction of pectin substances out of hydrolyzed fibers of beet bagasse, thickening the extract due to vacuum-evaporation to obtain a concentrate and its drying to achieve a powder-like state. For beet bagasse hydrolysis one should apply a solution at hydrogen peroxide concentration being 3.5-4.0%, the process lasts for 40-45 min. Moreover, hydrolyzed mass that contains fibers of beet bagasse and solution with residual content of hydrogen peroxide should be forced into extractor without separation. As a result, the content of pectin substances in ready-to-use product is increased, output is increased by 5-7%, its chromaticity is decreased by 20-30% and storage period is prolonged. Technological process for obtaining the concentrate is simplified that leads to decreased energy expenses for its manufacturing.

EFFECT: higher efficiency of manufacturing.
