Avocado pear is increasingly seen as an ideal fruit for the heath conscious in many countries.  The fruit is for fresh consumption.  Fruit pulp is often sold frozen with lemon juice spices (guacamole), as a cheese like fermented food ands as natural pulp for use in ice cream.Avocado oil is being strongly promoted for cosmetics and after refining, as high price food oil.  It has also been shown to be effective sunscreen oil.  The oil has been produced on a large scale in several countries notably Mexico, South Africa, Israel and New Zealand.  The main outlet for the oil is the cosmetics industry where it is highly valued for its beneficial effects on the skin.

Avocado oil uses:

  • Skin care
  • Edible oil
  • Health benefits

Processing Technology

  •        Skin Care Oil Processing

The whole fruit (skin, pulp and seed) is milled into a mesh.  Warm water, at 60ºC, is added to the mesh at the milling stage.  The mesh-water mix is then pumped into a malaxer where it is continuously mixed for an hour.  Subsequently, the mix is pumped into a 3 phase decanter that separates the mix into solids, water and oil.  The oil is clarified by  multi-cone centrifuge.
The resulting crude oil is refined by alkali refining, clay bleaching, deodorizing and winterizing.  This process effectively removes high levels of peroxides, free fatty acids, most of the chlorophyll, other colour producing substances, objectionable flavours adours and waxes from the oil. The final oil is packed in dark-colours glass bottles or specifically lacquered metals contained or drums that protect the oil from the negative influences of light and oxygen.

 

  •      Edible Oil Processing

The fruit is inspected and the washed with water under high pressure.  Any damaged or imperfect fruit is removed.  The high quality fruit subsequently skinned and pitted prior to processing.  The stone and skin are discarded prior to processing because they contain toxic ‘persins’. The resulting fruit pulp is malaxed (mixed in malaxers) for an hour.  Afterwards, the oil, water and solids are separated in a 3 phase decanter.  Subsequently, the oil is polished by a muilti-cone centridge to produce high quality oil.The resulting oil is either refined or packed unrefined.  The oil is packaged in antique dark-coloured glass bottles to protect it from the negative influences of light and oxygen.  The container headspace is flushed with nitrogen gas to prolong the oil shelf life.
