Pure Filtration for the Extra Virgin Olive Oil Insutry

GALVANORM

Why to filter EVOO?

Any EVOO evolves and does so negatively. The aging of the oil is values as a defect.

It is recommended the filtration to achieve its stabilization and an organoleptically superior EVOO, by avoiding the negative contribution of the evolutotion of the impurities ( anaerobic fermantation).

  • Does not affect the characteristics organoleptics of the EVOO.
  • It avoids negative effects of sediments which are generated by decantation.
  • There is no record of withholding of protective colloids, tocopherols, vitamins, etc.

Recommendations for the Filtering precess

We advise not to expose the oil to the air during filtration. In this way will avios an oxygen enrichment

that will accelerate the processes of auto-oxidation and, therefore, bad taste.

The oil should not be treated energetically, without exceeding the recommended pressure.

The good pumps choice are those with a low rotation speed for not create emulsions.

Correct olive oil filtration IN ADDITION to allowing adequate commercial presentation…

Increase the quality of the product for the consumer by:

  • The alimination of solids and moisture in the oil prevents during the frying the combustion of those occurs. Avoiding the formation of fumes and unpleasant odors.
  • Moisture during fying create Dampness results in sizzing skillet; Eliminated the water, this defect disappears.

Improve conservation conditions.

  • The sediments at the bottom of the packaging are rich in carbohydrates and protein substances that suffer anaerobic fermantation. Also, lipolytic enzymes which destroy fat molecules. The consequence of in a long-term conservation packaging, is the presence of odors to fermented, and the increase of acidity by released acids.

 


Types of filtering to retain impurities

Oils well decanted: If we want a perfect polished olive oil it must be filtered with the grade KA-5 before bottling.

Low decanted oils: We recommend to get a first step using grade KA-035 to achieve a seperation of the high solids and moisture content that still remains at the oil and that could not be eliminated due to the short decantation time.

After this filtration step the olive oil gets a smaill turbidity. If you want a total oil brightening, it would be necessary a second filtration step with the grade KA-5.

Filtraiton experience carried out in colloboration with the Institute of the Fat from Seville (CSIC). Picual olive oil from pressed oil evolved in deposit for a minimum of 5 moths.
