Guide on Groundnut Oil Processing, Health Benefits and Uses

Groundnut oil processing refers to the series of steps involved in extracting oil from groundnuts (also known as peanuts). This involves several stages, including cleaning, shelling, roasting, pressing, and filtering.

Groundnut oil, also known as peanut oil, is a vegetable oil that is derived from the groundnuts (peanuts). It is a popular cooking oil in many parts of the world due to its mild flavor, high smoke point, and health benefits.

Groundnut oil is rich in monounsaturated and polyunsaturated fats, which are considered heart-healthy fats. It is also a good source of vitamin E, an antioxidant that helps protect cells from damage.

In cooking, groundnut oil is often used for frying due to its high smoke point, which means it can be heated to high temperatures without smoking or burning. It is also used in salad dressings, marinades, and as a base for sauces.

When buying groundnut oil, it is important to choose a high-quality, unrefined oil that has been cold-pressed or expeller-pressed, as this will retain the oil’s natural nutrients and flavor.

It is also important to store the oil in a cool, dark place away from heat and light to prevent it from going rancid.

The first stage of processing involves cleaning the groundnuts to remove any foreign materials, such as stones, sand, and leaves. This is typically done using a vibrating sieve or a pneumatic cleaner.

Below is a step-by-step guide to groundnut oil processing:

Cleaning: The groundnuts are first cleaned to remove any foreign materials, such as stones, sand, and leaves. This is typically done using a vibrating sieve or a pneumatic cleaner. The cleaned groundnuts are then passed through a metal detector to ensure that no metal fragments are present.

Shelling: The outer shell or hull of the groundnuts is then removed. This can be done manually or using a mechanical sheller. Manual shelling involves cracking the shells with a wooden or metal pestle, while mechanical shelling involves using a machine that uses pressure and friction to remove the shells.

Roasting: The shelled groundnuts are then roasted to enhance their flavor and aroma. Roasting also helps to reduce the moisture content of the groundnuts, which improves the efficiency of oil extraction.

The groundnuts can be roasted using a variety of methods, including open flame, hot air, or microwave roasting.

Pressing: The roasted groundnuts are then pressed to extract the oil. This can be done using a mechanical press or an expeller.

A mechanical press uses a hydraulic cylinder to exert pressure on the groundnuts, while an expeller uses a screw to compress the groundnuts and extract the oil. The resulting oil and cake are separated using a filter.

Refining: The final step is to refine the oil to remove any impurities and to improve its shelf life. Degumming involves removing any gums and phospholipids from the oil, while neutralization involves removing any free fatty acids.

Bleaching involves removing any pigments or impurities, and deodorization involves removing any odors or flavors. The refined oil is then packaged and stored for distribution.

Overall, groundnut oil processing involves a series of steps to extract, refine, and purify the oil from groundnuts, resulting in a high-quality cooking oil that is rich in nutrients and flavor.
