How to Make Mustard Oil | Mustard Oil Production

Mustard oil is extracted from mustard seeds and has a strong pungent taste. Its main component is allyl isothiocyanate (more than 90%), which is mainly used in food seasonings such as seasonings and sauces. In this article, we will introduce the production process of mustard oil in detail step by step.
Mustard oil has two types: black mustard oil and white mustard oil. Black mustard oil is made by pressing the seeds of black mustard (also known as rod mustard) to form a cake, and then steam distilling it. White mustard oil is made by solvent extraction from the seeds of white mustard (also known as yellow mustard).

1. Raw material selection

   First, to ensure the quality of mustard oil, you need to choose mustard seeds with full seeds, large grains, and dark yellow color as raw materials.

2. Soaking

   Secondly, weigh the mustard seeds, add warm water (about 37℃) about 6-8 times the amount of mustard seeds, and soak for 25-35 hours.

3. Crushing

   Then, put the soaked mustard seeds into a grinder and grind them. The finer the better, to form a mustard paste.

4. Acidification

   Next, you need to adjust the pH value of the mustard paste to about 6 by using white vinegar.

5. Hydrolysis

   Put the mustard paste with the correct pH into the hydrolysis container. Then, place the container in a water bath. Make sure the water bath is at a constant temperature. Under the insulation condition of about 80℃, hydrolyze for 2-2.5 hours.

6. Distillation

   Next, place the mustard paste in the distillation device and use steam distillation to extract the spicy substances.

7. Separation

   Initially, the blend of oil and water undergoes distillation. Subsequently, an oil-water separator to employed to differentiate the two. This process results in the extraction of mustard essential oil.

8. Blending

   Mustard essential oil is subsequently mixed and evenly incorporated with vegetable oil, adhering to the specified formula proportion, to yield mustard oil.

9. Filling

   Finally, fill the mustard oil into a glass bottle that has been cleaned, disinfected, and dried in advance, labeled, and sealed to obtain the finished product.
