Optimization of Pectin Enzymatic Extraction from <i>Malus domestica</i> ‘Fălticeni’ Apple Pomace with Celluclast 1.5L

Pectin was extracted from apple (<i>Malus domestica</i> &#8216;Fălticeni&#8217;) pomace with Celluclast 1.5L, at doses of 20, 40, and 60 &#181;L/g of material. The temperature and time of extraction were varied on three levels&#8212;temperature&#8212;40, 50, and 60 &a...

description Pectin was extracted from apple (<i>Malus domestica</i> &#8216;Fălticeni&#8217;) pomace with Celluclast 1.5L, at doses of 20, 40, and 60 &#181;L/g of material. The temperature and time of extraction were varied on three levels&#8212;temperature&#8212;40, 50, and 60 &#176;C; time&#8212;12, 18, and 24 h. For each experiment, the extraction yield (R<sup>2</sup> = 0.8905), the galacturonic acid content (R<sup>2</sup> = 0.9866), and the degree of esterification (R<sup>2</sup> = 0.9520) of pectin was determined. Response surface methodology (RSM) was implemented via a Box&#8722;Behnken design, to optimize pectin extraction. In the optimum extraction conditions (temperature of 48.3 &#176;C, extraction time of 18 h 14 min, and enzyme dose of 42.5 &#181;L/g of pomace), the design predicted a 6.76% yield with a galacturonic acid content of 97.46 g/100 g of pectin and a degree of esterification of 96.02%. FT-IR analysis of the pectin sample obtained in these conditions showed a chemical structure similar to that of commercial apple and citrus pectin.
