Biodiesel, one of renewable bioenergy, has been produced from various resources such as vegetable oil, animal fats, used frying oils and microbial oils etc.1–3 Extensive study has been conducted on using edible oils, which limited by the availability of oil inventories, but these materials result in high sensitivity of prices to oil demand from industry.4–7 In order to not compete with edible o...

BACKGROUND Trans-fatty acids (TFAs), unsaturated fats with at least one double bond in the Trans configuration, are industrially formed in large quantities when vegetable oils are partially hydrogenated. This study was undertaken to quantify the amounts of the common fatty acids in several commercial oils marketing in Iran. METHODS The most consumed commercially available brands of vegetable ...

in this research the effect of oil type, process time ,temperature and pre-treating methods on moisture content, oil uptake, acidity and peroxide values of zucchini slices (cucurbita pepo. l) during deep fat frying process were investigated. the samples were pretreated by blanching (97 ºc for 5 min) and microwave (900 w for 2min) methods before frying process. frying experiments were carried ou...

This work proposes a new method for determination of the oxidative stability of edible oils at frying temperatures using near infrared emission spectroscopy (NIRES). The method is based on heating an oil sample at a fixed temperature, followed by the acquisition of the emission spectra with time using a home-made spectrometer with an acousto-optical tunable filter (AOTF) as monochromator. The i...

Background There has been an alarming increase in the dumping of Hong Kong’s municipal solid waste (MSW), predominantly food waste, in landfill (9,547 tonnes of MSW per day in 2013) [1]. One way of promoting an environmentally friendly method of minimising food waste is to turn the waste into energy by producing biodiesel from waste cooking oils. Biodiesel is a biodegradable fuel that can be ma...
