Oil Processing

Several different steps and methods are used in the processing of oils.

The quality, flavor and nutritional content of oils vary greatly

according to which processes are used.

 

Extraction

 

How an oil is extracted affects the nutritional quality of the oil

because heat, light and oxygen can destroy nutrients. Here are the most

commonly used extraction methods:

 

Expeller pressing-a process that uses mechanical pressure rather than

chemicals to extract oil from its source. Friction generates

temperatures that may be as high as 185 degrees Fahrenheit depending on

the hardness of the seed, grain, bean or nut.

 

Cold pressing-term sometimes used for expeller pressing at temperatures

below 120 degrees Fahrenheit. The only true cold pressed oil is extra

virgin olive oil, the first pressing of olives.

 

Vacuum extraction-recently developed vacuum (SpectraVac) expeller

process system that extracts oils in a non-oxygen and light-free

atmosphere at temperatures as low as 70 degrees Fahrenheit.

 

Solvent extraction-oils are extracted chemically with petroleum solvents

which destroy the oil's nutritional value.

I hope that helps
