METHOD OF RECOVERING PECTIN FROM SUNFLOWER ANTHODIA Russian patent published in 2005 - IPC

Abstract RU 2248364 C2

FIELD: vegetable-origin chemicals production.

SUBSTANCE: invention relates to technology of recovering pectin from vegetable material. In particular, recovery of pectin from sunflower anthodia comprises breakage of the latter, heating to denature proteins, extraction with acetone, hydrolysis-extraction of solid phase, separation of liquid phase, and concentration or drying thereof. According to invention, after extraction with acetone, extraction with liquid carbon dioxide is performed at superatmospheric pressure, after which second extract is separated at the same pressure and pressure is then abruptly dropped to atmospheric value over solid phase and solid phase is routed to hydrolysis-extraction stage.

EFFECT: reduced accident risk because of preventing toxic solvent from getting into desired product , reduced hydrolysis-extraction time, and decreased loss of pectin matters.
