ISO 9289 is an international standard on oilseed residues that discusses the determination of free residual hexane in oilseed residues to ensure oilseed products are safe for consumption.
ISO 9289 specifies a method for the determination of the free residual hexane content in oilseed residues after extraction with hydrocarbon-based solvents.
ISO 9289 on the determination of free residual hexane in oilseed residues is useful for:
Hexane has been widely used for oil extraction because of its easy oil recovery, narrow boiling point (63–69 °C) and excellent solubilizing ability. Hexane residue has been found toxic to humans and animals. High levels of hexane are considered neurotoxic and are classified as an air pollutant by the EPA.
ISO 9289 provides you with guidance on apparatus, sampling and sample storage, procedures for calibration, determination, expression of results, precision, etc.
The methods and procedures provided by ISO 9289 assist you in the determination of free residual hexane in oilseed residues, improving the quality and subsistence of oilseed residues and ensuring a reduction in the risk to animal health due to the high consumption of free residual hexane content.
