Graphite furnace atomic absorption spectrophotometry (GFAAS) has been widely applied to the determination of trace elements in food due to its selectivity, simplicity, high sensitivity, and its capability for accurate determinations in a wide variety of matrices. Edible oils are generally low in trace element concentrations, however, metals such as arsenic (As), lead (Pb), cadmium (Cd), chromiu...

Currently, most of the biodiesel is produced from the edible/refined type oil using methanol and alkaline catalyst. However, large amount of non-edible type oils and fats are available in our country. In this study, crude neem oil is used as alternative fuel for biodiesel production. The difficulty with alkaline transesterification of these oils have contained large amounts of free fatty acids ...

The content of fatty acids as well as the ratio between unsaturated and saturated fatty acids is important parameter for determination of nutritional value of certain oil. Therefore the newest trend in food processing industry is notifying the composition of edible oils and other food commodities for the content of each individual fatty acid. The main objective of this work was to identify the ...

The incorporation of natural antioxidants into fi lms and edible coatings can modify their structure, improving their functionality and applicability in foods, such as in fresh-cut fruits. This paper reviews the more recent literature on the incorporation of antioxidants from several sources into fi lms and edible coatings, for application in fruits and vegetables. The use of synthetic antioxid...

Milkfat has the highest price among all the edible oils and fats and plays a significant role in the economics, nutrition and physicochemical properties of milk and milk products. It can be admixed or replaced with less expensive oils and fats of vegetable or animal origins notably palm oils. Blending of edible fat with vegetable oils is a common practice in many countries to improve the physic...

Plant-derived essential oils (EOs) and oil compounds usually have a relatively high vapor pressure and are capable of reaching microbial pathogens through the liquid and the gas phase. Bioactivity of EOs in the vapor phase makes them useful as possible fumigants for stored commodity protection. The use of edible films as carriers of natural antimicrobials constitutes an approach for external pr...

The fatty acid composition of 10 different seeds from Nigeria was determined. The data showed that most seeds (except for Brachystegia eurycoma and Dacryodes edulis) could be placed into one major group; they all contained more unsaturated fatty acids ranging from 55.58 to 79.93% for Tamarindus indica and Monodora myristica, respectively. Two unsaturated fatty acids, namely oleic (21.97-60.68%)...

In this work, we introduce an NMR-based screening method for the fatty acid composition analysis of edible oils. We describe the evaluation and optimization needed for the automated analysis of vegetable oils by low-field NMR to obtain the fatty acid composition (FAC). To achieve this, two scripts, which automatically analyze and interpret the spectral data, were developed. The objective of thi...
