Fatty acid and vitamin E content of Nutrimaiz, a Sugary/Opaque-2 corn cultivar

Physicochemical properties, total phenol and tocopherol of some Acacia seed oils

“…Tocopherol content of the oil samples was estimated spectrophotometrically23 using Bathocuproine (Sigma) as the complexing agent for color formation with α‐tocopherol (Sigma) as a standard. All solvents used for the extraction and subsequent assay were purified and redistilled as previously described 24…”

“…All solvents used for the extraction and subsequent assay were purified and redistilled as previously described. 24 Viscosity measurement (in centistokes, cSt) was performed using an Oswald Kinematics viscometer (Schott Instrument GmbH, Mainz, Germany) with an attached water bath and a thermometer. The viscosities were determined at 30, 40, 50, 60, 70 and 80 • C. Specific gravity was also determined at a temperature range of 30-80 • C using a specific gravity bottle (BS 733, Jaytec, Hastings, UK).…”

Varietal differences in the vitamin E content of corn

“…Within a variety of com, the vitamin E content increases as the corn matures (Contreras-Guzman et al, 1982). This raises the question of whether the vitamin E content of varieties requiring less time to reach maturity is less than that of those requiring longer times.…”
