introduction: essential oils are used as flavoring agents in various foods. layer-by-layer (lbl) technique is a method in which the material is dipped into a series of different solutions containing oppositely charged polyelectrolytes. the aim of this study is to investigate the effectiveness of a multilayered edible coating with an antimicrobial compound (lemon and peppermint) in enhancing the...

Abstract— Today it is very much essential to use renewable fuels for power generation and transport applications because of energy security, environmental concerns, foreign exchange savings and socio-economic issues. The new process technologies developed during the last years made it possible to produce biodiesel from different vegetable oils comparable in quality to that of fossil diesel fuel...

The global energy consumption is expected to grow in a faster rate than the population growth. By 2030, an increase of 53% of global energy consumption and 39% of greenhouse gases emissions from fossil fuels is anticipated. Therefore, it becomes a global agenda to develop clean alternative fuels which are domestically available, environmentally acceptable and technically feasible. As an alterna...

The interest for the development of new active packaging materials has rapidly increased in the last few years. Antimicrobial active packaging is a potential alternative to protect perishable products during their preparation, storage and distribution to increase their shelf-life by reducing bacterial and fungal growth. This review underlines the most recent trends in the use of new edible coat...

Spent bleaching earth (SBE) is a waste generated by the edible oil industry that currently has limited options for beneficial reuse. In excess of ∼2 million tonnes per year of SBE is generated world-wide with major quantities available in the middle-east where significant volumes of edible oils are produced. Low pressure compaction followed by heat treatment at 150°C causes polymerisation of th...

An HPLC method with fluorescence detection has been developed for determination of eight polycyclic aromatic hydrocarbons (PAH) with four to six condensed aromatic carbon rings in edible oils and smoked products. The method employs preparative size-exclusion chromatography for efficient one-step lipid removal without saponification; benzo[b]chrysene is used as internal standard for quantificati...

Recently, sesame oil is highly appreciated by consumers due to its sensory qualities, antioxidants activity and nutritional benefits, despite its high price. Also, the detection and quantification of adulteration both are problem with increasing importance in the consumer’s health and food industry. The goal of this study was to use Fourier transform mid-infrared (FT-MIR) spectroscopy coupled w...

The application of high performance liquid chromatography time-of-flight mass spectrometry (HPLC/ TOF-MS) for the qualitation and quantitation of 11 synthetic antioxidants and preservatives in edible vegetable oil samples is reported here. The qualitation by HPLC/TOF-MS is accomplished with the accurate mass of the deprotonated molecules [M H] , along with the accurate mass of their main fragme...

It became a global agenda to develop clean alternative fuels which were domestically available, environmentally acceptable and technically feasible. Thus, biodiesel was destined to make a substantial contribution to the future energy demands of the domestic and industrial economies. Utilization of the non edible vegetable oils as raw materials for biodiesel production had been handled frequentl...

Edible films and coatings have emerged as an alternative packaging in food applications and have received much attention due to their advantages. The incorporation of essential oils in film matrices to give antimicrobial properties had been observed recently, and could be used as promising preservation technology. In this study, cassava starch-based edible coating incorporated with lemongrass e...
