FIELD: pectin production.
SUBSTANCE: claimed method includes swelling of plant raw materials, hydrolysis, and extraction by using of polyharmonic vibration of 15-50 Hz frequency, wherein swelling and hydrolysis are carried out in one step with hydrochloric acid solution followed by separation of solid and liquid phases and recycling of the last in swelling and hydrolysis step. Separated solid phase is diluted with water and used for extraction of pectin substances under vibration action. Further obtained extract is concentrated and purified in ultrafiltration apparatus to obtain pectin concentrate followed by dying thereof in vacuum drier.
EFFECT: accelerated method for pectin production; reduced reagent consumption.
