Extractions of apple pectins from apple pomace were performed using an experimental design with 2² factorial. The extractor agent was 5 % (w/v) citric acid and the variables were time (30, 50 and 80 min) and temperature (50, 75 and 100 °C). The best yield (16.8 %) was obtained using higher temperatures (100 °C; 80 min). Monosaccharide composition of the pectic fractions was similar to others already described.
