How is Groundnut Oil Made? 12 Super Facts You Should Know
Groundnut oil, also known as peanut oil, is one of the most widely used oils in kitchens around the world. Known for its high smoking point and mild flavor, it’s ideal for deep-frying, sautéing, and even baking. In addition to its culinary applications, groundnut oil has gained recognition for its numerous health benefits. But how is this versatile oil made? In this blog, we’ll explore the extraction process of groundnut oil and uncover 12 essential facts about its benefits, uses, and nutritional value.
Extraction Process of Groundnut Oil
Groundnut oil is extracted from the seeds of the Arachis hypogaea plant, commonly known as peanuts. The process of making groundnut oil typically involves the following stages:
- Cleaning: Raw groundnuts are cleaned to remove dirt, dust, and any other impurities.
- Roasting: The cleaned peanuts are roasted at a specific temperature to enhance their oil yield and flavor.
- Pressing: There are two primary methods used to extract oil from groundnuts—cold pressing and hot pressing:
- Cold Pressing: Involves mechanically pressing the seeds at room temperature. It preserves the oil’s natural nutrients, making it the preferred method for high-quality, unrefined oil.
- Hot Pressing: This method involves roasting the peanuts and then extracting oil using heat. While it may yield a higher quantity of oil, it can result in the loss of certain nutrients.
- Filtration: After extraction, the oil is filtered to remove any residual solids, resulting in a clean, clear oil ready for packaging and consumption.
- Refining (optional): Some groundnut oils are refined to remove impurities, enhance flavor, and extend shelf life. This process involves neutralizing the acid content, bleaching the oil, and deodorizing it.
Groundnut oil, especially the cold-pressed variety, is known for retaining a high level of its natural flavor and nutrients.
