As one of the main components of planet cell wall, pectin is abundant in nature and mainly extracted from plant leaves, roots and other parts (۱). Commercially pectin is extracted from different vegetable sources such as citrus peel (۸۵%), apple pomace (۱۴%), sugar beet pulp and others (۱%) (۲). Cationic derivatives of pectin were prepared by reacting pectin with ۳-chloro-۲-hydroxyl trimethyl ammonium chloride (CHPTAC) in presence of sodium hydroxide (NaOH). This quaternized pectin (QP) showed antimicrobial properties (۳). In a similar way, we synthesized quaternized pectin by reacting aqueous solution of citrus pectin with glycidyl trimethyl ammonium chloride in presence of sodium hydroxide (NaOH). After dialyzing the quaternized pectin solution using dialysis tubing cellulose membrane, we put the solution stay at room temperature for a few days in order for the excess water to evaporate. Then we let it dry to form thin films. The FT-IR spectrum of our synthesized quaternized pectin was compared with the sample in article (۳) and the result showed that the qaternized pectin was successfully synthesized and thus we expect that our synthesized quaternized pectin will show antimicrobial properties.
