Abstract
Metal corrosion is a major global concern in many economic sectors. Specifically, in the food and pharmaceutical industry, stainless steel is exposed to heat, water, and harsh cleaning chemicals. Through those exposures, food grade stainless steel must remain durable, corrosion free, and be easy to sanitize. These features are crucial because produced foodstuffs and drugs must comply with high purity and quality standards. Just a proper selection of stainless-steel grade can prevent corrosion phenomena that can be detrimental to the whole manufacturing process. In this book chapter, the corrosion and biocorrosion inhibition of stainless steel was investigated under harsh cleaning chemicals condition (10% HCl). For that, Chitin and Chitosan are extracted successively from the pink shrimp shells of Parapenaeus longirostris collected from the local market of Mehdia. Their corrosion and biocorrosion inhibition potential was evaluated via standard weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopymeasurement.
