Refined groundnut oil undergoes extensive processing, which includes bleaching, deodorizing, and sometimes filtering. This results in a clear, odorless oil with a neutral flavor.
Cold-pressed groundnut oil is extracted from groundnuts using mechanical pressing methods, without the use of heat. This preserves more of the natural flavors and nutrients.
These specialty oils may be cold-pressed or undergo unique processing techniques to create distinct flavors. Some examples include roasted peanut oil, which is made from toasted peanuts for a robust flavor.
Blended groundnut oils are a mixture of groundnut oil and one or more other types of edible oils, such as soybean oil or sunflower oil.
