Cooking oils play a crucial role in various culinary applications and have become an ubiquitous component of the modern diet, especially when it comes to frying. However, process repeated frying cycles exposes cooking high temperatures, which leads range physicochemical transformations. In this study four samples used(fried) - sunflower oil palm were collected analyses result revealed significa...

This study was conducted to produce biodiesel from a mixture of 5 different oils i.e, palm oil, used cooking soybean canola and sunflower through transesterification under mole ratio variations oil: methanol. The were mixed at total volume 300 mL with the same amount each oil used. blended 60°C for 1 h, ratios methanol set 1:3, 1:6, 1:9, 1:12, 1:15. results demonstrated that 1:6 resulted in hig...

The effect of boiling and roasting on the lipid quality, proximate composition, and mineral content of African walnut seeds (Tetracarpidium conophorum) was assessed. Results indicated that the quality of walnut oil significantly (p < .05) reduces with the treatments. Oils extracted from DBWN 60 min (Dried and boiled walnuts 60 min) and FBWN 60 min (Boiled fresh walnuts 60 min) were the most alt...

Oils with high content of free fatty acid (FFA) can be treated by acid esterification where an alcohol reacts with the given oil in the presence of acid catalyst. The investigated parameters include methanol to oil ratio, temperature and amount of catalyst. The optimum conditions for acid esterification which could reduce FFA content in the feedstock to less than 1.88% (acid value 3.76 mg KOH/g...

Biodiesel, as renewable and biological origin alternative diesel fuel, has been receiving a lot of concern throughout the world due to the energy needs and environmental awareness. However, at present, it is not economically feasible to use food-grade vegetable oils to produce biodiesel because of the surge in feedstocks price. Much attention has been devoted to the application of lower-cost fe...

Chemical degradation of edible oils has been studied using conventional spectroscopic methods spanning the spectrum from ultraviolet to mid-IR. However, the possibility of morphological changes of oil molecules that can be detected at terahertz frequencies is beginning to receive some attention. Furthermore, the rapidly decreasing cost of this technology and its capability for convenient, in si...

In this study, renewable and sustainable biofuel production from waste cooking oil its blends with diesel fuel are investigated in terms of specific properties. The named “Renewable Biofuel (RBF) 20” (20% biofuel–80% diesel), 50” (50% biofuel–50% 100” (100% biofuel). acid number, flash point, viscosity, cloud density, pour point properties the new Renewable Biofuels experimentally obtained comp...
