The deterioration of the environmental situation necessitates the use in the human diet of ingredients that have increased detoxification activity against toxicants of various nature, including lead, one of the most toxic and dangerous heavy metals, extremely common in the environment. It seems relevant to use raw materials of plant origin to implement the task, including sugar beet pulp, a secondary product of sugar production, which contains a fairly large amount of dietary fiber. The purpose of this work is to improve the technological regimes for the production of dietary fiber from sugar beet pulp with a high sorption capacity for lead ions. Combined sorbents from sugar beet pulp were obtained according to the technology modified by the authors. The process of extracting dietary fiber from sugar beet pulp was studied using pre-treatment of raw materials with an extremely low frequency electromagnetic field. Technological regimes for the production of combined sorbents of plant origin with high detoxification activity with respect to lead ions have been experimentally established. The binding capacity of solutions of combined sorbents was assessed by the trilonometric method modified by the authors. Optimization of technological regimes with the help of mathematical programming methods has been carried out. The obtained optimal technological regimes make it possible to reduce the cost of energy resources spent on the technological process by reducing the duration of thermal hydrolysis-extraction. In comparison with the traditional method, the developed technological mode allows increasing the binding capacity of the final product with respect to lead ions by more than 20 %.
