The production process of fats and glyceridic oils is a complex and multi-stage process that involves several chemical reactions and physical treatments.
In the chemical industry, fats and oils are used in a wide range of applications, including food processing, cosmetics, pharmaceuticals, and soaps.
The production process of fats and oils can be broken down into several stages, including vegetable oil extraction, refining, and hydrogenation.
In this article, we will take a closer look at each of these stages and how they are used to produce high-quality fats and oils for various industrial applications.
- Vegetable Oil Extraction
The first stage in the production of fats and oils is the extraction of oil from vegetable sources.
This is typically done through a process known as solvent extraction, which involves the use of a solvent to extract the oil from the plant material.
The plant material is first crushed and then mixed with the solvent.
The solvent is then separated from the oil, and the oil is extracted from the solvent using methods such as centrifugation or filtration.
The resulting oil is then separated from any remaining solvent using a distillation process.
- Refining
After the vegetable oil has been extracted, it typically needs to be refined in order to remove any impurities or unwanted compounds.
This process involves several steps, including degumming, neutralization, and bleaching.
Degumming is the process of removing gums and other impurities from the oil, which can cause it to become thick and cloudy.
This is typically done using a solvent such as acetone or ethanol.
Neutralization involves removing any remaining acidity or alkalinity from the oil, which can affect its flavor and color.
This is typically done using a base, such as sodium hydroxide, to neutralize the acidity.
Bleaching involves removing any color or pigment from the oil, which can affect its appearance and flavor.
This is typically done using a bleaching agent such as chlorine or oxygen.
- Hydrogenation
The final stage in the production of fats and oils is the process of hydrogenation, which involves adding hydrogen
