Oxidative stability of Menhaden/Soybean oil blends
With the approval of menhaden oil pending, the food industry is trying to incorporate marine oils high in omega-3 fatty acids into food systems. The main problem obstructing its use as a food ingredient is fishy/painty flavors which occur with low levels of oxidation. The purpose of this study was …

Determination of tocopherol isomers and fatty acids in cottonseed oil and oil blends during accelerated storage
… in cottonseed, corn, canola, peanut and pecan oils and 50% cottonseed oil blends and also commercially available cottonseed oil containing TBHQ. The oil samples were stored at 65°C for a total of 120 days. The α and γ-tocopherol concentration of each sample were determined using a Waters, model …

A comparative study of the thermal oxidative stability of high oleic acid sunflower and polyunsaturated soybean oil blends
… sunflower (HOSO) and polyunsaturated soybean oil (PUSB) blends ranging from 0.0% to 100.0% of each vegetable oil. Each blend was evaluated in quadruplicate over an eleven day period with 300 minutes of heating at 180°C per day. Thermal oxidative stability was determined by changes in peroxide …

Investigation of diesel soot-mediated oils and additive package on wear
… to study the effects of soot contaminated engine oil on wear. The variables that were considered were the Base stock (Group1, Group2), Dispersant level and ZDP level. The above three variables were formulated at two levels: Low (-1), and High (1), which resulted in 23 matrix (8 oil blends). Soot …

Development of a multi-regime tribometer and investigation of zinc dialkyldithiophosphate tribofilm development in the presence of overbased calcium sulfonate
… additive universally used in engine and gear oil formulations, was studied in detail with respect to tribofilm production. As typical oil formulations contain an assortment of additives, the development of these films in the presence of other additives was studied. Of these, overbased …

Oxidative stability and ignition quality of algae derived methyl esters containing varying levels of methyl eicosapentaenoate and methyl docosahexaenoate
… Tests were conducted with synthetic algal oil blends manufactured from various sources to match the fatty acid compositions of several algae strains subjected to varying removal amounts of roughly 0 - 100 percent LC-PUFA. In addition, tests were also conducted with real algal methyl esters …
