Abstract
The main objective of this work was to study the valorization of agricultural wastes and the by-products of food in our country. To this end, we opted for the extraction of pectin from melon rinds. Pectin extracted was precipitated by two types of salts: aluminum sulphate and aluminum chloride. The pectin yields obtained by means of aluminum sulphate and aluminum chloride as precipitating agents are 6.916% and 9.166% respectively. The pectins IR spectra obtained revealed that these pectins showed 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. 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 are especially found in pectins. Pectins precipitated with 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, the environmental gain being the reduction of environmental pollution load.
