The composition of some commercial Citrus oils, lemon, sweet orange, and tangerine, designated for aromatherapy, was examined before and after partial evaporation in a stream of nitrogen. The intact oils contained the expected mixtures of mono- and sesquiterpenes, with hydrocarbons dominating and lesser amounts of oxygenated analogues making up the remainder. Gas chromatography-mass spectrometr...

Stored fish are frequently contaminated by foodborne pathogens. Lipid oxidation and microbial growth during storage are also important factors in the shelf-life of fresh fish. In order to ensure the safety of fish items, there is a need for control measures which are effective through natural inhibitory antimicrobials. It is also necessary to determine the efficacy of these products for fish pr...

In field trails on lemongrass (Cymbopogon citrates), the effect of growth regulators, viz. indole butyric acid (IBA) and mepiquat chloride (MC), and their mode of application was studied to assess their effects on growth, oil yield and hormonal contents. The results suggested that application of growth regulators had no favourable effect on growth and oil yields in lemon grass. However, applica...

In the present study, we investigated the fumigant potential of five edible essential oils (EOs) against Sitophilus oryzae and their phytochemical residues in treated grains. Among the tested EOs, peppermint oil proved significantly effective (P ≤ 0.05) on S.oryzae at 400 μl/L air concentration, inducing 83 and 100% mortalities in with-food and without-food conditions respectively over 72 h exp...
