Know All About Mechanical Extraction and Degumming Process for Edible Oil Until the 1950s, most vegetable oil production was by mechanical extraction. Though solvent extraction took over it, the use of presses and screws continues in less developed countries to fully extract vegetable oils. But in most developed countries, big machines are used to extract and refine vegetable oil to remove impurities to become healthy edible oils. The degumming of vegetable oil is a refining process to remove phosphatides, also called lecithin or gums. This article will discuss vegetable oil's mechanical extraction and degumming using the right machines made by reputed manufacturers for the different degumming processes.
What is the mechanical extraction of vegetable oils? Extraction of oils from plants has existed since ancient times, and evidence shows olive oil extracted from olives dating back to 6000 BCE. Vegetable oils were extracted mostly from plant seeds for thousands of years using mechanical devices like screws or presses. There was no use of organic solvents during such mechanical extraction of vegetable oils until the solvent extraction in the 1950s. But still, even the high-end machines made by reputed manufacturers use presses and screws to extract oil from many plant seeds. Proper cleaning and destoning of the seeds are essential before the extraction process for increasing the efficiency of these machines. Minimal operating staff is essential to handle, control and supervise these machines to have low operating costs for maximum ROI.
What is the degumming of vegetable oil? Vegetable oils like olive oil, groundnut oil, sunflower oil, palm oil and others have become essential for the food industry and other industries. Hence, they need to be in the purest form to be free of the impurities in the crude oil. There are many refining processes to remove such harmful impurities using the best machines and refining plants. Degumming of vegetable oil is a refining process to purify vegetable oil to become healthy edible oil to avoid many ailments. It removes phosphatides, also known as gums or lecithin, that cause instability in the vegetable oils like soybean oil. Lecithin, with the common name phosphatidylcholine, is the source of gums that makes the oils cloudy and unsuitable for commercial sale. Hence the degumming process of edible oil is essential for making it clear and transparent for cooking and other purposes worldwide.

What are the different degumming processes of edible oil? Degumming is the first and most important refining process for purifying vegetable oils, not only to eliminate harmful phosphatides. It is also an important refining process to improve the quality of the vegetable oil and avoid its decomposition becoming dark because of thermal instability and refining losses. Depending on the type of phosphatides, different degumming processes of edible oil include the following, among others. Water degumming is the simplest and more cost-effective edible oil refining process than others to leave less material for removal during neutralization. It uses the removed gums as a valuable by-product. Acid degumming is useful for refining animal fats by using a small amount of water and acid water at controlled temperatures to remove metal impurities, among others. Enzymatic water degumming removes high phospholipid content using the PLC or phospholipase C enzyme to break down the phospholipids into DAG, diacylglycerol, and water-soluble phosphate-bearing ester fragments to reduce gums and minimize oil losses and increase ROI or yield. A deep enzymatic degumming is by small amounts of acids to effectively remove gums by adjusting the pH values by PLA phospholipase enzyme to convert hydratable and nonahydrate gums into FFAs or free fatty acids and gums. The above facts will convince anyone to use the best machines made by Mectech, with over forty-five years of experience in the mechanical extraction and degumming process of edible oil. mechanical_extraction degumming_of_vegetable_oil degumming_process_for_edible_oil
