Mustard Essential Oil

ABSTRACT It is estimated that nontyphoidal Salmonella causes approximately 1 million illnesses and 378 deaths per year in the United States. Reduction of Salmonella-related foodborne infections can be achieved through application of food antimicrobials. Essential oils in combination with other antimicrobials can be added to food products to reduce the levels of the organism below the infectious dose for healthy individuals. The purpose of this study was to investigate the antimicrobial efficacy of white mustard essential oil (WMEO) against serovars of Salmonella and its potential to be used with carvacrol or thymol to control Salmonella. Results showed that WMEO at the highest concentration of 0.84% (v/v) compared with the positive control had approximately a 6- to 7-log reduction for all serovars. It was found that no difference in susceptibility existed among the serovars tested (P > 0.05). In addition, the MICs were determined to be 0.5, 0.02, and 0.02% for WMEO, carvacrol, and thymol, respectively, against Salmonella Typhimurium. The fractional inhibitory concentration index was calculated. A score of 1 indicated an additive effect occurred when WMEO was combined with thymol or carvacrol. Combining WMEO with carvacrol or thymol indicated that the concentration of individual essential oils needed to inhibit Salmonella can be reduced using these combinations and warrants further study to determine potential use in controlling Salmonella in commercial food products.

Shed Light

The genus Sideritis, belonging to the Labiateae family, is represented by more than 150 species distributed mainly in the Mediterranean regions. Member of the genus have been used as beverages, flavorings, and medication. We aimed to shed light on the antioxidant potential of the essential oil of Sideritis rubriflora Hub.-Mor. In this study, antioxidant capacity (DPPH and ABTS radical scavenging, CUPRAC and FRAP, phosphomolibdenum assay, and metal chelating activity) of essential oil of S. rubriflora was investigated with colorimetric methods. Also, essential oil composition of the plant was determined by gas chromatography/mass spectrophotometry (GC-MS). 48 components, representing 95.4% of essential oil of S. rubriflora were identified. β-pinene (10.7%) and Germacrene D (10.7%) were the main constituents of the essential oil. Generally, essential oil of S. rubriflora has shown moderate free radical, reducing power, metal chelating. The reported results supported that the possible use of essential oil of S. rubriflora is a source of natural agents for phytopharmaceutical applications.
