Abstract
The main objective of this work was to study the valorization of agricultural wastes and byproducts of food in our country; we opted for extracting pectin from melon rinds. Pectins are a very useful class of active ingredients and are identified as multifunctional compounds with several pharmacological activities. Pectin yields obtained using aluminum sulfate and aluminum chloride as precipitating agents is 6.916% and 9.166% respectively. The pectins IR spectra obtained revealed that these pectins have two broad absorption bands at 3400 cm-1 and 3396 cm-1 which seems to correspond to the type of vibration ν elongation of the hydroxyl group (OH). The presence of peaks at about 1740 cm-1 and 1269 cm-1 appears to correspond to the C=O bonds of the uronic acids and esters. The bands found in the pectins extracted with aluminum sulfate (1743 cm-1) and (1239.15 cm-1) can be attributed to sugars or non-esterified acid that especially are found in pectins. Pectins precipitated by aluminum sulfate showed a microstructure similar to those of commercial pectins. These substances could be a primary source for the development of new products for many industries.
