Antibacterial Activity of Pomegranate, Orange and Lemon Peel Extracts Against Food-Borne Pathogens and Spoilage Bacteria In vitro and on Poultry Skin

The objective of this study was to determine the more efficient antibacterial activity of chitosan among irradiated and nonirradiated form. Chitin was isolated from shrimp and then converted into chitosan. The initial molecular weight of chitosan was 1.6 X 106 Da and after step by step pretreatments using alkali, acid and H2O2, the final molecular weight was found to be reduced to 2.7 X 104 Da and the degree of deacetylation (DD) was 70%. Chemical treatments deproteinated and decalcified the chitin. Chitosan, the deacetylated form of chitin, was dissolved in lactic acid and then irradiated to perform antimicrobial activity. To conduct the experiment, seven different strains of bacteria were isolated from spoiled orange and it was found that chitosan was more effective to inhibit the growth of these bacteria. The more efficient result was found with irradiated chitosan than the non-irradiated one and the efficiency was consistently along with the increasing of the radiation dose. The best antimicrobial activity was observed with 32 kGy. DOI: http://dx.doi.org/10.3329/bjm.v28i1.11809 Bangladesh J Microbiol, Volume 28, Number 1, June 2011, pp 45-47

Origanum Onites

Food poisoning is a common cause of illness and death in developing countries. Essential oils (EOs) could be effective and safe natural preservatives to prevent and control bacterial contamination of foods. However, their high sensitivity and strong flavor limit their application and biological effectiveness. The aim of this study was firstly the chemical analysis and the antimicrobial evaluation of the EOs of Origanum onites L. and Satureja thymbra L. obtained from Symi island (Greece), and, secondly, the formulation of propylene glycol-nanovesicles loaded with these EOs to improve their antimicrobial properties. The EOs were analyzed by GC-MS and their chemical contents are presented herein. Different nanovesicles were formulated with small average sizes, high homogeneity, and optimal ζ-potential. Microscopic observation confirmed their small and spherical shape. Antibacterial and antifungal activities of the formulated EOs were evaluated against food-borne pathogens and spoilage microorganisms compared to pure EOs. Propylene glycol-nanovesicles loaded with O. onites EO were found to be the most active formulation against all tested strains. Additionally, in vitro studies on the HaCaT cell line showed that nanovesicles encapsulated with EOs had no toxic effect. The present study revealed that both EOs can be used as alternative sanitizers and preservatives in the food industry, and that their formulation in nanovesicles can provide a suitable approach as food-grade delivery system.
