Contamination of cottonseed oil by mineral oil

Determining Oil Content of Cottonseed

Engine Performance Test of Cottonseed Oil Biodiesel

Two cottonseed oil biodiesel samples (cottonseed oil methyl esters, COME) produced in Clemson lab, together with other two commercial cottonseed oil biodiesels were evaluated on their engine performance with the No. 2 diesel fuel as a reference. The results revealed that emission of CO, CO2 and NOx from cottonseed oil biodiesels was lower than that of the No. 2 diesel fuel. CO decreased by 13.8...

Triacylglyceride Composition of Cottonseed Oil by HPLC and GC

The triacylglyceride components of cottonseed oil were isolated and positively identified by a combination of high performance liquid chromatography (HPLC) and gas chromatography (GC). Both reversed-phase HPLC and capillary GC were capable of separating the oil into triacylglyceride peaks. These peaks were isolated by HPLC and their component acyl groups were converted to fatty acid methyl este...

Evaluation of Near Infrared Reflectance for Oil Content of Cottonseed

The status of ongoing research to use near infrared reflectance spectroscopy (NIRS) to measure cottonseed oil content is summarized. A data set of 36 seed samples consisting of a single replication of six entries grown at two locations for 3 yr was used to generate prediction equations for oil content of cottonseed (Gossypium hirsutum L.). The equations were generated with NIRS based on seed-oi...
