Types of Groundnut Oil
Groundnut oil is available in the market in refined and filtered form. Generally, oils are refined through various processes via expression and solvent extraction, etc. While Food Safety and Standards Regulation, 2011, permits the addition of antioxidants in groundnut oil, these shall be within the prescribed limit. Refined oil: This type of oil has been purified with chemicals to remove any suspended particles, toxic substances, flavour components, colour and odour, thereby leaving behind clear and pure oil. Filtered oil: Obtained by the traditional cold-pressing method, this is filtered once or twice to remove suspended particles. They are simply filtered and bottled with no further processing. Unrefined or filtered oils retain the savoury flavour of the groundnuts from which they are derived.
