Undesirable substances in vegetable oils: anything to declare?

Masking Undesirable Flavors in Fish Oils'

The odor of fish oil used medicinally may require masking by flavoring materials. During a search for suitable masking materials, fresh, specially refined menhaden oil having a minimum of flavor was stored with and without added flavoring materials for 5 days at 75° F and for longer periods at several lower temperatures. In initial preliminary screening tests with 66 different flavoring materia...

Lubricant basestocks from vegetable oils

Oil Chemical Research. USDA l-ARS-NCAUR. 1815 N. U;liuersity Street, Peoria, IL 61604, USA Accepted 8 October 1999 Compared to the lubricants made of petroleum, vegetable-based lubricants are much more biodegradable but inferior in many other technical characteristics. The basestock typically contributes to more than 80% of lubricant and must meet performance criteria in such aspects as cleanli...

Progress in Vegetable Oils Enzymatic Transesterification to Biodiesel - Case Study

The Determination of Stigmastadienes in Vegetable Oils

The development by collaborative study of a standardised method for the determination of the stigmastadienes content in vegetable oils is described. The procedure involves the isolation of the unsaponifiable matter in the oil ands its fractioning on a silica gel column. The fraction containing the steroidal hydrocarbons is then analysed by capillary gas chromatography and the quantitative asses...

Chemically Modifying Vegetable Oils to Prepare Green Lubricants

Chemically modifying vegetable oils to produce an alternative to petroleum-based materials is one of the most important emerging industrial research areas today because of the adverse effects of petroleum products on the environment and the shortage of petroleum resources. Biolubricants, bioplasticizers, non-isocyanate polyurethanes, biofuel, coating materials, biocomposites, and other value-ad...
