Conducted a detailed comparative analysis of the preservative effects of Coriandrum sativum plant extract and the chemical preservative sodium benzoate in fruit juice. Designed and executed experiments to evaluate microbial growth, shelf- life extension, and sensory properties. Utilized microbiological techniques to monitor and quantify microbial activity in treated juice samples. Analyzed and interpreted data to assess the efficacy and safety of natural vs. chemical preservatives. Collaborated with a team to present findings in a comprehensive report.
