The addition of copper chlorophyll and its derivatives (Cu-Chl) to vegetable oils to disguise them as more expensive oils, such as virgin olive oils, would not only create public confusion, but also disturb the olive oil market. Given that existing detection methods of Ch-Chl in oils, such as LC-MS are costly and time consuming, it is imperative to develop economical and fast analytical techniq...

The global method for detection of extraneous oils in different kinds of olive oils as a new method for identification of adulterations is applied using HPLC and GC data by calculations ECN (equivalent carbon number) and R (which is the ratio r ECN42/ r ECN44 for genuineness of all olive oils) according to IOOC method. In this research the global method and ECN42 (difference between the actual ...

The oil of Schinus molle exhibited the maximum fungitoxic activity during the screening of some essential oils against some common storage and animal pathogenic fungi. It showed absolute toxicity against animal pathogens and mild activity against storage fungi. The effective concentrations of the oil varied from 200 to 900 ppm. The toxicity of the oil persisted up to 80 degrees C and 90 days of...

Fatty acids characteristic of ruminant-animal fat have been found to be present in significantly lower proportions in samples from the depot fat of persons dying of ischaemic heart disease (cases) than in specimens from persons dying of unrelated causes (controls). Although such acids are also present, in lesser amounts, in hydrogenated marine oils, this case-versus-control difference is diffic...

This article summarizes experimental knowledge of the efficacy, modes of action and applications of herbal extracts and organic acids as feed additives for pigs. Herbal extracts comprise a wide variety of herbs, spices and, most importantly, essential oils. Organic acids, characterized as short-chain weak acids, are widely distributed in nature as normal constituents of herbal or animal tissues...

Bacterial response to increasing amounts of the volatile oils varies significantly according to species of bacteria tested. Among the four species examined, Escherichia coli was the most resistant to the oils, followed by Neisseria sicca, Bacillus subtilis, and Staphylococcus aureus. The oils of Artemisia tridentata seem to have the same degree of antibacterial action as oils obtained from A. n...

Escherichia coli O157 is an important foodborne pathogen affecting human health and the beef cattle industry. Contamination of carcasses at slaughter is correlated to the prevalence of E. coli O157 in cattle feces. Many associations have been made between dietary factors and E. coli O157 prevalence in cattle feces. Preharvest interventions, such as diet management, could reduce the fecal preval...

Jatropha curcas (L.) is a perennial plant of the spurge family (Euphorbiaceae). Recently, it has received much attention as a potential source of vegetable oil as a replacement for petroleum, and, in particular, the production of biodiesel. Despite the interest that is being shown in the large-scale cultivation of J. curcas, genetic resources remain poorly characterized and conserved and there ...

Since we have been exposed to excessive amounts of stressors, aromatherapy for the relaxation has recently become very popular recently. However, there is a problem which responds to light with the essential oil used by aromatherapy. It is generally believed that singlet oxygen is implicated in the pathogenesis of various diseases such as light-induced skin disorders and inflammatory responses....

Background and objectivesToday, medicinal plants phytobiotics that contain flavonoids, alkaloids, essential oils are widely used in animal feed. These additives have many benefits, including increasing liver function preventing certain diseases. The is one of the organs plays a key role insulin-mediated regulation metabolism as well glucose, whole-body, lipid homeostasis. aim this study was to ...
