Results turned out quite positive: Amount of orange peels used/g as possible the morning of.! The antifungal activity in terms of zone of inhibition and minimum inhibitory concentration (MIC) of the essential oil was tested against ten food borne fungal strains and ten bacterial strains. Pressures ranging from 80-150 bars with temperatures, ranging from 28-60oC were employed. Along with this it can also be used as safer and alternative means of food preservation. The isolated limonene will then be analyzed by polarimetry and the percent recovery from orange peels will be determined. Get customized instruction with our STEM education experts. The isolation of the compound limonene from citrus fruit can be confirmed by the IR spectrum, gas chromatography, and the smell of the product.
