METHOD OF THE BIOGEL PRODUCING FROM MARINE MACROPHYTES Russian patent published in 2018 - IPC A23L29/25 

FIELD: technological processes.

SUBSTANCE: method includes preparation of algae, their grinding and processing in an acidic medium, washing in fresh water with infusion, hydrolysis, homogenization, packing. Hydrolysis is carried out for 1–2 hours using ultrasound in the cavitation mode simultaneously with ultra fine grinding, at that, the washed algae is placed in to the rotor-cavitation extractor container, filled with hot water 40–60 °C at the algae mass and water ratio of 1:1, adding the sodium bicarbonate to pH 7.0 and homogenizing.

EFFECT: invention provides an increase in the sodium alginate yield with a reduction in energy consumption.
