“…From previous studies (Cuoco, Mathe, Archier, Chemat, & Vieillescazes, 2009;Garcia-Ayuso & Luque de Castro, 1999;Vilkhu, Mawson, Simons, & Bates, 2008;Wang & Weller, 2006), the particle size was considered one of the important factors that can affect the efficiency of polyphenol extraction from orange peels. Thus, preliminary experiments on orange peels of 0.5, 1.0, 1.5, 2.0 and 2.5 cm 2 gave final yields of 3.44%, 3.65%, 4.32%, 4.41% and 4.38%, respectively.…”
