A method for making low-etherified liquid pectin includes washing a raw pectin-containing material, pressing, protopectin hydrolysis, cooling, separation of phases, neutralization, filtering, and concentration. The protopectin hydrolysis is carried out with an acid at рН 1.2-2.7, then extraction is carried out at a temperature of 40-50 °С with water. Trilon B is added to the separated and neutralized extract, and then etherifying the pectin is with carried out. |
