Abstract
FIELD: food industry.SUBSTANCE: invention relates to a method for producing pectin from plant raw materials. The method for producing pectin from plant raw materials includes a step of wet grinding of the raw material to a particle size of not more than 3 mm in the presence of acidified water. The extraction step is carried out at pH 1.8-3.0, a temperature of 25-90°C, for 5-240 minutes at a hydromodule of 1:15-1:25. The step of cooling the suspension is carried out to 40-65°C and its neutralisation to pH 3.3-4.0. Then, the step of pressing and centrifugation is carried out to separate the liquid phase of the pectin extract from the solid residual particles of the raw material. The step of membrane ultrafiltration and diafiltration of the pectin extract is carried out using membranes with a cut-off threshold of 20-100 kDa to obtain a purified concentrated pectin solution. The step of vacuum drying of the purified solution is carried out at a temperature of 80°C in a tubular falling film evaporator with simultaneous mechanical vapour recompression to obtain dry pectin. The extraction is carried out in a loop extractor, in the circulation circuit of which there is a circulation pump, a heat exchange device and a static mixer-turbulator.EFFECT: increasing the efficiency of pectin extraction by reducing the temperature-acid load on the raw material, reducing the processing time and preserving the native properties of pectin biopolymers, which makes it possible to increase the pectin yield and its gelling ability, while simultaneously reducing the energy consumption and resource costs of the process.1 cl, 1 dwg, 1 ex
