The objective of this research is to examine the feasibility of storing pomegranate juice in containers constructed from SS 304 alloy, commonly referred to as Ever Silver, or SS 316 L alloy. The corrosion resistance of both SS 304 and SS 316L alloy was evaluated across different environments, including a water system, a pomegranate juice system, and a pomegranate juice system with added sugar (5000 g), utilizing AC impedance spectroscopy for measurement. Key corrosion parameters, including charge transfer resistance, impedance, phase angle, and double layer capacitance, were calculated. The findings indicate that SS 316 L alloy exhibits superior corrosion resistance compared to SS 304 alloy across all three systems. Consequently, it is recommended that pomegranate juice and pomegranate juice with sugar be stored in containers made of SS 316 L alloy, which is also applicable to the water system.
