The aim of the research work is to develop a method for processing beet pulp – a waste of sugar production. The study proposes a method for extracting pectin from beet pulp with a solution of weak citric acid. Characteristics of beet pulp such as total acidity, pH value, total sugar, carbon, nitrogen, volatile matter, hydrogen, fixed carbon, ash content have been determined. The pectin was extracted. To achieve the highest yield of pectin, the extraction conditions are optimized. The physical and chemical characteristics of the obtained pectin have been determined: the degree of esterification, color parameters, the methoxyl component, water activity, identification of pectin using infrared spectroscopy with Fourier transform. The torrefaction of pectin extraction waste to obtain biofuel was carried out. A feature of the proposed method is its low waste, since the waste of sugar production is used as a raw material, and weak and cheap citric acid is used as an extractant. The obtained pectin (the output of pectin was 21 ... 29%) can be used in the food industry (as a stabilizer, gelling agent, thickener).
