Mechanical methods: An oil press is the simplest available method to press the dry biomass to extract oil. Oil presses are successfully used for the extraction of oil from crop seeds (e.g., sunflower, canola, and olives). In the case of algae, the biomass requires drying prior to pressing it through the press, which is a significant cost making this option less cost-effective.
Similarly for oil soluble annatto extraction method, the maximum extraction of bixin (0.99 %) was found with castor oil at 120°C for 1 hr and least bixin (0.03 %) was recorded with mustard oil at ...

Olive oil extraction is the process of extracting the oil present in olive drupes, known as olive oil.Olive oil is produced in the mesocarp cells, and stored in a particular type of vacuole called a lipo vacuole, i.e., every cell contains a tiny olive oil droplet. Olive oil extraction is the process of separating the oil from the other fruit contents (vegetative extract liquid and solid material).
