to evaluate the effect of essential oils of oregano on performance, immune response in broiler chickens arian, an experiment in a completely randomized design with a total of 500 broiler chicks, in 5 treatments, including the control diet, control diet + 100 mg/kg protexin, control diet + 150 mg/kg avilamysine and control diet + 200 and 400 mg/kg oregano oil with 4 replicates and 25 chicks were...

The present study was conducted to characterize the in vitro antimicrobial activities of 3 essential oils [oregano, rosemary, and a commercial blend of essential oils (BEO)] against pathogenic and nonpathogenic bacteria and to evaluate their effects on broiler chicken performances. The chemical composition of the essential oils was determined using the gas chromatography interfaced with a mass ...

The sensory, microbiological and physicochemical attributes of fresh meat stored at 5 and 15 degrees C were affected by the combined effect of volatile compounds of oregano essential oil and modified atmosphere packaging conditions (40% CO2/30% N2/30% O2, 100% CO2, 80% CO2/20% air, vacuum pack and air). It was found that the extension of shelf life of meat samples depended on the packaging cond...

BACKGROUND The potential of Origanum syriacum L. to become a cultivated crop in Lebanon rather than being harvested from the wild was investigated at the production, postharvest and economic levels. Three irrigation schemes were tested on growth parameters of cultivated oregano plants. In order to identify the most quality-preserving drying technique, air-, oven (30 °C)- and freeze-dried oregan...

AIMS To investigate the potential use of oregano essential oil as an antimicrobial agent in liquid soap for hand washing and for food contact surface cleaning. METHODS AND RESULTS Oregano essential oil (O.E.O.) was emulsified in liquid detergent solution. This was challenge tested against a commercial antimicrobial soap in hand washing trials using natural flora. Soap with O.E.O. was as effec...

Recently, the natural spices and herbs such as rosemary, oregano, and caraway have been used for the processing of meat products. This study investigates the antioxidant activity of 13 spices commonly used in meat processing plants. The hot water extracts were then used for evaluation of total phenolic content, total flavonoids content and antioxidant activities. Our results show that the hot w...

Natural antioxidants are receiving increasing attention in human and animal nutrition because of their association with food quality characteristics and immune responses [1,2]. Among a variety of plants bearing anti-oxidative constituents, the Labiatae family (mint plants) has been attracting the greatest interest [3], with particular attention to products from oregano (Origanum vulgare L.) and...

Commercial Oregano oils with high concentrations of carvacrol have been vigorously promoted as antiviral agents effective against colds and ‘flu, including the pandemic H1N1 virus. However there seems to be no evidence to support these claims. Furthermore, since carvacrol itself is known to be toxic, so-called “carrier oils”, such as olive oil, have been included in formulations to ameliorate t...

Background: The aim of this study was to investigate the effects of chitosan coatings, oregano essential oil, and their combination on microbial quality of chicken fillet during 12 days in refrigerator temperature. Methods: Oregano oil was extracted by water distillation and then different concentrations of oregano oil (1% and 2%) were used for film preparation. Microbiological tests were carri...

A healthy, balanced diet is essential for both physical and mental well-being. Such a diet must include an adequate intake of micronutrients, essential fatty acids, amino acids and antioxidants. The monoamine neurotransmitters, serotonin, dopamine and noradrenaline, are derived from dietary amino acids and are involved in the modulation of mood, anxiety, cognition, sleep regulation and appetite...
