abstract: olives belong to the family of olea europaea l. is a popular fruit tree. the fruit and the oil extracted from it is consumed worldwide particularly in the mediterranean regions. in this study changes in the fatty acid composition of the oil extracted from olive fruit during the course of maturation is investigated. this work is concerned with the best harvesting point when oleic acid ...

for many years, assessment of olive oil quality and itsauthenticity confimation has been of great importanceto guarantee olive oil safety in compliance with legislations. these include the investigation of olive oil purityand quality by analyzing several parameters such as fattyacid composition, sterols, phenolic compounds, triacylglycerol and etc, through performing conventional andadvanced hy...

objectives the link between dietary fat and heart disease has been established for decades. although, the atherogenic effect of saturated fatty acids is somehow controversial, the cardioprotective effects of polyunsaturated fatty acids (pufa) are clearly documented. this study investigated the effects of different dietary oils on serum fatty acid composition in rat. methods six week male wistar...

This study was conducted to evaluate the diurnal effect on essential oil yield and composition of Ledum palustre L. grown in northern Inner Mongolia, China. Essential oil content and composition were determined and compared as a function of different harvesting times viz. 7:00 AM, 11:00 AM, 3:00 PM, 7:00 PM, and 11:00 PM within a day. The essential oil obtained by hydrodistillation was investig...

olive oil in general due to it monounsaturation, stability, nutritive value, consistency, taste andaroma might be considered as a valuable and luxury oil. annual importation of olive oil to iran frommediterranean countries is on a large scale although some olive oils are produced in iran particularly in the northand some plantation has been applied in different provinces particularly in fars. t...

the effect of four types of shortening including a commercially vegetable oil (as control), palm olein (po), palm stearin (ps), and a blend of the latter two oils with rapeseed oil (bf) on the rheological properties of cookie dough was determined by using dynamic oscillatory measurement testing. all of the obtained dough treatments showed weak liquid viscoelastic behavior. their storage (g ) an...

the leaves of arum conophalloides (araceae) were used in some west areas of iran as a dessert. the aerial parts of the herb were collected from sahneh mountains, kermanshah province, west of iran and was hydrodistilled by klevenger-type apparatus. composition of the essential oil was determined by gc and gc/ms. totally, 18 components (92% of total essential oil) were identified. the oil contain...

To study oil contents and fatty acid composition among the samples of Jatropha curcas L. seeds were collected from Dehradun, Uttarakhand. Soxhlet extraction method and gas chromatography (GC) were employed to determine the oil contents of Jatropha seeds and the fatty acid composition of Jatropha oil. The seed oil contents (dry basis) was 46.27% .Physicochemical properties shows acid value (36.4...
