A new method of extracting avocado oil using heat and additional water was studied.
The purpose of this study was to test the feasibility of a new industrial processing technique of avocado oil extraction which consisted of pulping, initial heating, addition of water, second heating, and finally centrifugation of the "avocado milk".
The quantity of oil extracted was about 60% of the total oil content of the pulp, with the fruit pulp being comprised of about 20% of oil.
Alternatives suggested for future research include:
1. The addition of coarse salt to the fruit pulp before milling.
2. The use of an homogenizer.
3. Increasing centrifugal force for purer extraction. With improvements in the preparation of avocado pulp, the oil yield should be greater.
