In the present investigation natural phenolic antioxidants were extracted from Jojoba seed waste. Samples of defatted jojoba meal (JSM), detoxified residue (DMR) and shell (JSH) subjected to extraction by using various solvents: 70/30 (vol/vol) ethanol/water, methanol/water 60/40 acetone/water. Total phenolics content (TPC) is measured according Folin-Ciocalteu method. In addition, solvent extr...

This paper presents a statistical study on the AC Breakdown Voltage (BDV) of Refined, Bleached and Deodorized Palm Oil (RBDPO) olein under influence moisture. Different moisture contents RBPDPO were prepared by drying RBDPO in oven at different time intervals. The BDV test was performed whereby distance between 2 electrodes set to 1 mm. analyses data for carried out based normal, lognormal Weib...

Blends (30:70, 50:50 and 70:30 w/w) of Moringa oleifera seed oil (MoO) with palm olein (PO), palm stearin (PS), palm kernel oil (PKO) and virgin coconut oil (VCO) were prepared. To determine the physicochemical properties of the blends, the iodine value (IV), saponication value (SV), fatty acid (FA) composition, triacylglycerol (TAG) composition, thermal behaviour (DSC) and solid fat content (S...

1H NMR fingerprinting of edible oils and a set multivariate classification regression models organised in decision tree is proposed as stepwise strategy to assure the authenticity traceability olive their declared blends with other vegetable (VOs). Oils ‘virgin oil’ ‘olive categories mixtures most common VOs, i.e. sunflower, high oleic hazelnut, avocado, soybean, corn, refined palm olein dester...

Aquaculture activity has increased the population of crab, hence increasing the generation of related wastes, particularly the shell. In addition, the number of molting process in crabs compounds further the amount of waste shell generated. As such, in the present work, the application of the waste crab shell as a source of CaO in transesterification of palm olein to biodiesel (methyl ester) wa...
