How much oil do we get from 1 kg of groundnut seeds?

April 28, 2023

Groundnut oil, also known as peanut oil, is a popular vegetable oil that is commonly used in cooking and various culinary applications. Groundnut oil is extracted from the seeds of the groundnut plant, which is a legume native to

South America but now widely cultivated in various parts of the world, including Africa and Asia.

One of the most common questions asked by people who are interested in using groundnut oil is how much oil can be obtained from a certain amount of groundnut seeds, such as 1 kg. The answer to this question is not straightforward, as there are various factors that can affect the amount of oil that can be extracted from groundnut seeds.

On average, it is estimated that 1 kg of groundnut seeds can yield between 35% to 50% oil, depending on the extraction method. This means that you can expect to get approximately 350-500 ml of oil from 1 kg of groundnut seeds. However, it is important to note that the oil yield can vary depending on several factors, such as the quality of the seeds, the extraction method used, and the equipment used for extraction.

The quality of the seeds used is an important factor that can affect the oil yield. Groundnut seeds that are fresh, clean, and free from contaminants are more likely to yield a higher amount of oil compared to seeds that are old, dirty, or damaged. It is therefore important to use high-quality seeds to obtain the best possible oil yield.

Another important factor that can affect the oil yield is the extraction method used. There are several methods that can be used to extract oil from groundnut seeds, including mechanical pressing, solvent extraction, and cold-pressing. The method used can affect the quality and quantity of the oil obtained. For instance, mechanical pressing can yield a higher amount of oil but may also result in a lower-quality oil compared to cold-pressing, which is a slower and gentler method that can result in a higher-quality oil.

The equipment used for extraction is also an important factor that can affect the oil yield. Different types of equipment, such as hydraulic presses, expeller presses, and screw presses, can yield different amounts of oil depending on their design and capacity. It is therefore important to choose the right equipment for the desired oil yield and quality.

In addition to the factors mentioned above, the variety of groundnut seeds used can also affect the oil yield. Some varieties of groundnuts are known to have higher oil content than others. For instance, Spanish groundnuts are known to have a higher oil content compared to other varieties.

Finally, the amount of oil that can be obtained from 1 kg of groundnut seeds can vary depending on various factors, such as the quality of the seeds, the extraction method used, and the equipment used for extraction. On average, you can expect to get between 350-500 ml of oil from 1 kg of groundnut seeds, but the actual yield may vary depending on the specific circumstances. By using high-quality seeds, the right extraction method, and the appropriate equipment, you can maximise the oil yield and obtain a high-quality groundnut oil for your culinary needs.
