METHOD FOR PRODUCTION PECTIN EXTRACT Russian patent published in 2005 - IPC

FIELD: technology for production of pectin-containing food additive.

SUBSTANCE: claimed method includes refuse washing with subsequent washing water separation, addition therein of sodium chloride and treatment on cation-exchange resin in H⁺-form; refuse hydrolysis-extraction with treated washing water; separation of pectin extract-containing phase, neutralization and demineralization thereof on anion-exchange resin in OH^--form; and concentration to produce target product. In process of hydrolysis-extraction pressure in reaction mixture is periodically dissipated up to value, which provides liquid phase boiling, and increased again up to starting value.

EFFECT: increased pectin yield with simultaneous decreasing of technological cycle time.
