CANTERI, Maria H. G.; MORENO, Lirian; WOSIACKI, Gilvan and SCHEER, Agnes de P.. Pectin: from raw material to the final product. Polímeros [online]. 2012, vol.22, n.2, pp.149-157. Epub Apr 10, 2012. ISSN 0104-1428. http://dx.doi.org/10.1590/S0104-14282012005000024.
Pectin, probably the most complex macromolecule in nature is a hetero-polysaccharide containing predominantly residues of galacturonic acid (GalA). This polymer, which belongs to a group of dietary fibers, is widely used as a gelling agent and stabilizer in the food industry. The main industrial processing to obtain pectin is based on the solubilization of protopectin from apple pomace and citrus peels, which is done under low acidity and heated conditions. Recent studies have reported the extraction of pectin from new raw materials and using different extraction conditions, which influence the yield and quality of the final product, and may improve the rheological properties. This review describes the structure, sources, applications and industrial extraction processes, as well as the analysis methods of physicochemical characterization of pectin.
