Introduction
Essential oils have been used for centuries for their antimicrobial properties in food preservation. These natural plant extracts have gained attention in recent years as an alternative to synthetic preservatives due to their effectiveness and safety. The antimicrobial properties of essential oils are attributed to their complex chemical composition, which includes compounds such as terpenes, phenols, and aldehydes that have been shown to inhibit the growth of bacteria, fungi, and molds.
This project aims to explore the antimicrobial properties of essential oils in food preservation and their potential applications in the food industry. The research will focus on identifying the most effective essential oils, optimal concentrations, and application methods to enhance the shelf life of food products while maintaining their safety and quality.

Project Research Overview:
The project research on the antimicrobial properties of essential oils in food preservation aims to investigate the effectiveness of selected essential oils as natural preservatives in various food products. The study will involve testing the antimicrobial activity of essential oils against common foodborne pathogens, determining the optimal concentrations for inhibitory effects, and evaluating the sensory quality and shelf life of treated foods.
The research will utilize both in vitro and in situ experiments to assess the antimicrobial efficacy of essential oils in different food matrices. Various analytical methods, such as agar diffusion assays, minimum inhibitory concentration (MIC) tests, and sensory evaluations, will be used to measure the antimicrobial activity, safety, and consumer acceptance of essential oil-treated foods.
Overall, this project aims to contribute to the growing body of knowledge on natural food preservatives and provide valuable insights into the potential applications of essential oils in the food industry. By understanding the antimicrobial properties of essential oils and their impact on food preservation, this research can help improve the safety, quality, and sustainability of food products for consumers worldwide.
