Vegetable oils need refining processes like degumming to remove impurities and increase stability and shelf-life. Essential or edible oils have impurities other than triglycerides, including proteins, phospholipids, sugar, phlegmatic, etc. These non-glyceride impurities will react with the glycerides to form colloids, also known as gum impurities. Not removing these gum impurities will make the vegetable oil not only have no stability but also affect the effect of deep processing and oil refining. And using non-degummed vegetable oil forms an emulsified oil in the alkaline process to affect the refining operation, creating oil loss, auxiliary material consumption and other issues.
Hence this article will discuss the best degumming process for edible oil and the dewaxing of RBO or rice bran oil to make it healthy and nutritious.
What is the dewaxing of RBO?
Rice oil made from the bran of rice has existed for thousands of years because of its many benefits, especially being trans-fat free. Also, RBO or rice bran oil has many biological activities like decreasing low-density lipoprotein levels, lowering cholesterol, reducing blood pressure and preventing colorectal cancer. The significant reason for such many health benefits is it has a good balance of mono and polyunsaturated fatty acids, almost in the 1:1 ratio. Here, the dewaxing of RBO comes into play to remove the waxes or triglycerides to make it the first choice for people with an awareness of healthy living.
What are the benefits of the best plant for dewaxing of RBO?
Waxes or glycerides in the crude RBO with higher melting points get removed by gradual cooling and separating the saturated glycerides from the oil. The entire RBO refining process occurs at higher temperatures, like 10 to 20 C, to avoid crystallization and amalgamation of the waxes and saturated triglycerides. The best plant made by reputed manufacturers will provide many benefits for the dewaxing of RBO.
- Provides excellent designs for crystallizer and cooling systems to enable nucleation even at high temperature
- Enables the formation of the large nuclei crystal size below equilibrium temperature for easy separation
- Does not allow mechanical disturbance in the crystallization process using specially designed agitators to have different speeds
What is the degumming of edible oil?
Most of the edible oils in the crude have many impurities like glycerides and non-glycerides to need refining to be pure and healthy. Degumming of vegetable oil is the first refining process to remove the gums, which are non-glyceride impurities like proteins, sugar, phospholipids, etc. Removing these non-glyceride impurities through the degumming process will also prevent the two from combining to form emulsified oil in the alkaline process affecting refining and deep processing. Also, degumming removes the hydrated and non-hydrated impurities with different methods to make the vegetable oil pure and healthy.
What are the different degumming processes for edible oil?
The best plant for degumming of vegetable oil made by renowned manufacturers maximizes the edible oil quality, yield, and shelf life. The degumming process using it will minimize gum content, loss of neutral oil, and utility and operating costs in the oil refinery. Also, it increases operational efficiency and reliability apart from boosting service life or uptime and minimizing 3-MCPD precursors. Also, the experienced manufacturers produce plants for different edible oil degumming processes, including the following, among others.
- Water degumming is by adding hot water to crude oil to hydrate and separate the impurities and further by centrifugation and filtration.
- Acid degumming is by adding acids to the crude oil to break down the phospholipids and other impurities to have higher yields and is suitable for removing non-hydratable impurities.
- Enzymatic degumming is the new method of using enzymes instead of acids to break the impurities to produce higher-quality edible oils.
Mectech from 1978 makes plants with advanced features for dewaxing for RBO and degumming of edible oil to be useful in over 20 countries.
