Background Eucalyptus trees (family Myrtaceae) are well-known for their high foliar content of several classes of secondary metabolites and these have a strong effect on the feeding patterns of several species of marsupials and at least some insects. Best known are the essential oils, which is mostly a mixture of terpenoids, but there are also significant concentrations of flavonoid and formyla...

Eicosapentaenoic acid (EPA) is a polyunsaturated fatty acid present in fish oils used for omega-3 enriched diets. The natural cis double bond geometry can be transformed to the trans configuration during the deodorization process utilized in the food industry. The analytical discrimination of the possible five monotrans regioisomers represents a limiting step for the recognition and structure-a...

Nowadays, essential oils are used in different products such as food as natural antioxidants, antibacterial and flavoring compounds (1). Essential oils are used as a replacement for chemical preservatives such as butylated hydroxytoluene (BHT) and tertiary butyl hydroquinone (TBHQ) that can threaten human health as cancer promoters (2). Nearly 3000 different essential oils are known today, and ...

The positional isomers trans-anethole and estragole are present in essential oils extracted from many aromatic plants used in traditional medicine, and have largely been used as flavoring agents in the food industry. There are many studies describing the biological activities of these essential oils; however, few studies have been performed to determine the biological effects of these substance...

In Brazil, and mainly in the State of Bahia, crude vegetable oils are widely used in the preparation of food. Street stalls, restaurants and canteens make a great use of palm oil and soybean oil. There is also some use of castor oil, which is widely cultivated in the Sertão Region (within the State of Bahia), and widely applied in industry. This massive use in food preparation leads to a huge a...

The beneficial health effects of inclusion of n-3 PUFA from fish and fish oils in the human diet have been extensively investigated in the past three decades beginning with the initial reports on the reduced prevalence of IHD in Greenland Inuit. Extensive nutritional and clinical studies continue to indicate that higher intakes of EPA and DHA derived from marine sources can reduce the risk of c...
