Utilisation of pectin isolated from tomato peel waste as an eco-friendly tin corrosin inhibitor

Pectin as the methylated ester of polygalacturonic acid has a wide range of applications in pharmaceutical, cosmetic and food industry. Commercially, pectin is extracted from citrus peels and apple pomace. However, some agricultural and food processing waste, like tomato peel have attracted the interest of researchers due to their high amounts of pectin [1-2]. In that context, this work presents evaluation of pectin isolated from tomato peel as an eco-friendly tin corrosion inhibitor, using gravimetric, and electrochemical, i.e. potentiodynamic (PP) and impedance spectroscopy (EIS) methods. The measurements were done in solution composed by 2 % (w/v) NaCl and 1 % (v/v) acetic acid, at 25 °C in absence and presence of different concentrations of tomato peel pectin (TPP), as well as commercial apple pectin (CAP), in order to compare TPP corrosion efficiency. The results showed that TPP inhibition efficiency values are slightly higher (59.79 % and 64.08 for PP and EIS) compared to that of CAP (54.93 % and 60.05 % for PP and EIS), which points out pectin extracted from tomato peel act as an efficient tin corrosion inhibitor. Thus, un-utilized tomato biomass could be used as a promising, low-cost industrial resource for pectin isolation and implementation for development of new, eco-friendly corrosion inhibitors, instead of ordinary chemical and toxic ones.
