We developed wine formulations containing plant essential oils and oil compounds effective against foodborne pathogenic bacteria Escherichia coli O157:H7 and Salmonella enterica. HPLC was used to determine maximum solubility of antimicrobials in wines as well as amounts of antimicrobials extracted by wines from commercial oregano and thyme leaves. Activity of essential oils (cinnamon, lemongras...

there are numerous problems for using essential oil due to its low solubility in water, high vapor pressure and chemical and physical instability. use of nano-emulsions is a good idea for decreasing side effect of the essential oils and enhance their efficiency as well as delivery to hot spot. in addition, nano-emulsion system make smaller size particles and increase stability and shelf-life of...

The aim of this study was determine the volatile compounds, antimicrobial and antioxidant activity of the essential oils (EOs) of cinnamon (Cinnamomum verum), fenugreek seeds (Trigonella foenum greacum), ginger (Zingiber officinale) and marjoram (Origanum majorana) widely consumed in Egypt. EOs showed a great variety of compounds in their chemical compositions, Trans-cinnamyl aldehyde, terpinen...

The objective of the present research was to develop cinnamon oil nanoemulsions using soy protein isolate and lecithin as food grade natural emulsifiers. For this purpose, stable cinnamon oil nanoemulsion (droplet diameter of 141.2 nm) prepared by ultrasonic emulsification. The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of free and nanoemulsified cin...

Anthracnose caused by Colletotrichum gloeosporioides has been destructive during pepper fruit production in outdoor fields in Korea. In vitro antifungal activities of 15 different plant essential oils or its components were evaluated during conidial germination and mycelial growth of C. gloeosporioides. In vitro conidial germination was most drastically inhibited by vapour treatments with carva...

Antibacterial activity of 19 essential oils was screened against four test bacteria namely Pseudomonas aeruginosa NCIM 5029, Staphylococcus aureus NCIM 5021, Salmonella typhimurium NCIM 2501 and Bacillus subtilis NCIM 2063. Varying degree of antibacterial activity was recorded with the highest being depicted by Cinnamomum zeylanicum followed by Cymbopogon ciatrus and Carum copticum, against all...

S. Epidermidis is among the most frequently isolated microorganisms found in -infection related to implanted devices and the formation of biofilm will be more resistant compared to the planktonic form. This study was carried out to determine the effect of coating on stainless steel orthopaedic implants surfaces with cinnamon oil and chitosan as bioadhesive to prevent biofilms formation of S. Ep...

The antioxidant and antimicrobial activities of the extracts from peel, leaves, and bark of mangosteen (Garcinia mangostana L.), and some essential oils such as cinnamon and citrus were investigated. The antioxidant activities (IC50) of peel, leaves, and bark extracted, which were evaluated by DPPH method, were 5.94, 9.44, and 6.46 μg/ml, respectively. Either cinnamon or citrus essential oil sh...

The purpose of this paper was to evaluate the shelf-life of chitosan and cinnamon oil coated chicken meat nuggets under refrigeration conditions. Three types of coated nuggets were developed viz., Meat coated with Chitosan (1%) and Cinnamon oil (0.05%) (T1), direct addition of Chitosan and Cinnamon oil in emulsion (T2) and nuggets dipped in Chitosan and Cinnamon oil (T3) and were aerobically pa...
