Palm oil is liquid at room temperature, generally around 25°C (77°F).
Palm oil's physical state is influenced by its composition and the specific type of palm oil. Palm oil itself is a mixture of triglycerides, and its different fractions have varying melting points.
-
Palm Oil vs. Palm Olein: Palm oil can be fractionated into palm olein (the liquid fraction) and palm stearin (the solid fraction). Palm olein has a lower melting point, typically between 18–20°C (64-68°F), making it liquid at room temperature.
-
Factors Affecting Melting Point: The precise temperature at which palm oil becomes liquid can vary slightly depending on the specific composition of the oil, which is affected by factors like:
- Geographic origin of the palms: Different growing regions can yield palm oil with varying fatty acid profiles.
- Processing methods: Refining and fractionation processes can influence the final melting point.
- Blending: Palm oil is often blended with other vegetable oils, which can alter its melting point. For instance, blending palm olein with soybean, sunflower, or canola oil can modify its properties.
In summary, while the broader term "palm oil" can include fractions that are solid at room temperature, palm olein, the most common liquid fraction, is liquid around 25°C (77°F).
