Olive oil pomace is the main solid by-product from the olive oil extraction standing for 35–40% of the total weight of olive processed in the mill (Chanioti & Tzia, 2018).
What happens to the olives after olive oil is made?
The physical composition of the olive is skin, pulp, the stonewall and the kernel. Through all of this physical matter is the water and oil which are mostly extracted from the olive during processing. After going through the extraction process about 35% of the fruit will be left as olive cake.
What is the byproduct to making olive oil?
Olive pulp
Related. Olive pulp (also called olive pomace or olive cake) is what remains after olives are crushed and the olive oil is extracted.
What happens when oil is mixed with water?
So what happens when you try to mix oil and water? The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water.

The highest detection rates were observed for the residues of fenthion, dimethoate and endosulfan. The highest occurrence and levels of pesticides were observed in extra virgin olive oil whereas results pointed that residues in olive oil from variety of olives with high oil yield may be higher.
Is olive oil healthier than vegetable oil?
If you choose to consume oils, extra virgin olive oil tends to be a much healthier choice than most vegetable oils and vegetable oil blends.
What is the water footprint of olive oil?
Over the studied period, the green water footprint in absolute terms of Spanish olive oil production represents about 72% in rainfed systems and just 12% in irrigated olive orchards. Blue and grey water footprints represent 6% and 10% of the national water footprint, respectively.
