Other authors used milder conditions for pectin extraction. Indeed, Joe and Luzio (2000) extracted pectin from lemon peel at mild pH (3–3.3), while Pagan and Ibarz
(1999) used temperatures ranging from 40 to 80 °C for pectin extraction from fresh peach pomace.Pectin has been extracted from many plant by-products and fruits such as sugar beet pulp, peach pomace and
especially citrus (orange and lemon) and apple pomace which are the main sources for commercial pectin production
(May 1990; Fernandes et al. 2010).
