Understanding Cold Press Oil Extraction

What temperature should a cold press oil machine maintain?

Direct Answer

There is no single temperature number that proves every oil is cold pressed. Codex defines cold-pressed oils by mechanical extraction without applied heat; specific product standards and customer requirements must also be considered.

Detailed Engineering Analysis

A barrel setting is not necessarily the temperature of oil leaving the machine. Record both the process and the measured oil temperature using an appropriate calibrated instrument. Confirm the operating specification for the selected MMEC model and seed before making a label claim. Avoid treating an advertised limit such as 50°C or 60°C as a universal certification. Temperature control should be assessed alongside extraction conditions and finished-oil quality.
