Abstract

A complete study was conducted through manufacturing of Microencapsulation of Basil Oil Powder (MEBOP) and Microencapsulation of Thyme Oil Powder (METOP) to evaluate the anti-bacterial activity against aquatic pathogens. An oil-in-water emulsion were prepared using gum with dextrin and the resultant matrix was spray dried with the average yield of 45% w/w of MEBOP and 50% w/w of METOP. Total oil content in the encapsulated powder in both were found to be 24.39% w/w of MEBOP 25.80% w/w of METOP respectively. Scanning Electron Microscopic (SEM) analysis was also done to confirm the encapsulation of oil and study possible structure of matrix. Microencapsulated powders were further subjected for antibacterial activity against aquaculture pathogens like Vibrio harvey, Vibrio parahaemolyticus, Bacillus cereus, Aeromonas sp, E. coli and Salmonella sp. Results were compared against the respective oils at different concentrations. Phyto- constituents from Basil oil and Thyme oil like Thymol, Linalool, and Methyl chavicol were quantified using HPLC (High-Performance Liquid Chromatography) and GC (Gas Chromatography) which may be responsible for this activity. Furthermore, stress studies were conducted at 60 °C to understand the stability of Encapsulated oil powders to this and its commercial usage in formulations.
