Olive oil extraction

OLIVE OIL EXTRACTION Imerys talcs maximize virgin olive oil production

Imerys talc is an effective solution for increasing virgin olive oil yield throughout the full duration of the olive producing campaign. Talc works with all olive types and is particularly effective with difficult olives.

Imerys talc aids processing in olive oil production where it:

  • Absorbs the natural emulsifier found in olives, allowing more olive oil to be extracted – particularly from ‘difficult’ fruit which contain too much or not enough water
  • Reduces fruit solids in the oil which cause cloudiness and higher sediment levels, improving oil clarity
  • Allows milling at lower temperatures
  • Reduces the need for oil degrading techniques, eg. heating the paste or adding water, improving oil quality
  • Increases plant production capacity
  • Lowers emulsion levels in wastewater – often used to irrigate nearby fields
  • Is a natural, environment friendly which does not pollute wastewaters

As talc is inert, it does not affect the chemical properties of the olive paste, nor the color or flavor of the final product.
