This paper presents a brief review on the current status of biodiesel production and its performance and emission characteristics as compression ignition engine fuel. This study is based on the reports on biodiesel fuel published in the current literature by different researchers. Biodiesel can be produced from crude vegetable oil, non-edible oil, waste frying oil, animal tallow and also from a...

The concentration and the chemical composition of the essential oils obtained from different samples of Cymbopogon citratus were evaluated. Among the 12 samples investigated (11 dried leaf samples and fresh plant leaves), seven presented essential oil concentrations within the threshold established by the Brazilian legislation. The moisture content was also determined and the majority of the sa...

Enzymatic transesterification by using lipase as catalyst has become more attractive for the production of biodiesel due to easy separation of products such as glycerol and fatty acid esters. Comparative studies of enzyme catalyzed transesterification of three less attended non edible oils (jatropha, karanja and putranjiva) have been discussed. The maximum yield has been obtained at 3:1 molar r...

The present study was carried out to examine the changes in functional properties of cholesterol-removed compound whipping cream made by β-CD treated cream and palm oil. Six different ratios of cream to palm oil (10:0 as control, 9:1, 8:2, 7:3, 6:4, and 5:5, v/v) were tested. The overrun percentage increased with an increased amount of palm oil. When the ratio of cream to palm oil was 10:0 (con...

A total of 39 aroma compounds were detected in the essential oil of Citrus nagato-yuzukichi Tanaka (nagato-yuzukichi) by gas chromatography-mass spectrometry (GC-MS). The essential oil was characterized by a high percentage of monoterpene hydrocarbons (12 components, 90.52%). The composition pattern of essential oil in C. nagato-yuzukichi was fairly similar to that of Citrus sudachi Hort. ex Sh...

This research was aimed at investigating the essential oil production, chemical composition and biological activity of a crop of pink flowered oregano (Origanum vulgare L. subsp. vulgare L.) under different spatial distribution of the plants (single and binate rows). This plant factor was shown to affect its growth, soil covering, fresh biomass, essential oil amount and composition. In particul...

The chemical properties of oil from arils of both ripe and unripe ackee (Blighia sapida) were evaluated with a view to investigating the variations in their domestic and industrial applications. The chemical analyses of ripe and unripe aril oils respectively in different locations showed the percentage yield of oil from 54.91±2.75 to 78.25±3.91; 37.78±1.51 to 54.61 ± 2.18, iodine values of 90.0...

The composition of the essential oil hydrodistilled from the aerial parts of 18 individual Artemisia herba-alba Asso. plants collected in southern Tunisia was determined by GC and GCMS analysis. The oil yield varied between 0.68% v/w and 1.93% v/w. One hundred components were identified, 21 of of which are reported for the first time in Artemisia herba-alba oil. The oil contained 10 components ...
