The utilization of edible oil would be generally considered of a high grade with a low margin for error given the fact that it is consumed. Contaminants which adversely impact the appearance and performance of edible oils are very prevalent in the product during the process so far. Usually preceded by Degumming and alkali based processes, Bleaching removes detrimental contaminants that are otherwise not effectively removed earlier in the refining process.
As a process, Bleaching is simple. It involves the addition of a clay absorbent in the oil which effectively removes colour and reduces impurities such as chlorophyll, residual soap and gums, traces of metals etc. While the process may seem simple, the parameters under which it is conducted are critical. Moisture levels, temperature, contact time and vacuum are just a few of the parameters that affect the process. There are 4 processes via which bleaching can be executed:
- 2Bleaching
- 3Filtration
For the layman, bleaching simply improves oil quality through the interaction of the oil with the absorbent. The parameters around which the process is based, are altered to create the best possible environment for optimal Chemical Mixing and Bleaching.
Bleaching Process Of Vegetable Oil
The vegetable oil bleaching process is a crucial step in refining edible oils to remove impurities and improve their color, flavor, and shelf life.
The vegetable oil bleaching process begins with pre-treatment of the crude oil, which includes degumming and neutralization. Degumming removes phospholipids, while neutralization eliminates free fatty acids. Once these preliminary steps are complete, the oil is ready for the bleaching stage.
In the bleaching plant, the oil is mixed with bleaching earth or activated carbon, which are adsorbent materials used to attract and bind impurities. These impurities can include pigments like chlorophyll and carotenoids, as well as traces of metals and oxidation products that affect the oil's quality.
The process involves heating the oil to a specific temperature, usually between 85°C to 110°C (185°F to 230°F), to enhance the efficiency of the adsorbents. The oil-adsorbent mixture is then agitated to ensure thorough contact between the oil and the adsorbents. This mixture is typically processed under vacuum to prevent oxidation and degradation of the oil.
After sufficient contact time, which can vary depending on the type of oil and the extent of impurities, the oil is filtered to separate the spent adsorbents from the bleached oil. The filtration process is critical, as it ensures that no adsorbent residues remain in the final product.
The clarified oil, now free of unwanted colorants and contaminants, is then subjected to further refining steps, such as deodorization, where any remaining odors and volatile compounds are removed. This results in a high-quality, stable, and visually appealing vegetable oil suitable for consumption.
The vegetable oil bleaching process within a bleaching plant is a meticulously controlled operation designed to purify and enhance the quality of edible oils. By effectively removing impurities and improving the oil's properties, this process plays an essential role in the production of refined vegetable oils.
