The Spicy Essence of Mustard Oil
Mustard oil has a long and rich history dating back centuries. Its use can be traced to ancient civilizations in India, China, and Egypt, where it was prized for its culinary properties and medicinal value. Mustard oil has been a staple in Indian cuisine for centuries, where it is used in a variety of dishes, from tempering vegetables to marinating meats.
In recent years, mustard oil has gained popularity beyond its traditional use in Indian cuisine. Its unique flavour, high smoke point, and potential health benefits have attracted attention worldwide.
Mustard oil is a rich source of omega-3 fatty acids, which are essential for human health. These fatty acids have been linked to various health benefits, including:
Heart Health:
- Cholesterol reduction: Mustard oil is rich in unsaturated fatty acids, particularly oleic acid, which has been shown to help lower LDL (“bad”) cholesterol levels. High LDL cholesterol levels are a risk factor for heart disease.
- Reduced heart disease risk: By lowering cholesterol levels, mustard oil can help reduce the risk of heart attack, stroke, and other cardiovascular diseases.
- Skin health:
- Antioxidant protection: Mustard oil contains antioxidants, such as vitamin E, that can help protect the skin from damage caused by free radicals. Free radicals are harmful molecules that can contribute to premature ageing and skin problems.
- Improved skin hydration: Mustard oil can help moisturize the skin and improve its elasticity, making it appear smoother and more youthful.
- Digestive health:
- Stimulates digestion: Mustard oil can help stimulate the secretion of digestive enzymes, which can aid in the breakdown of food and improve digestion.
- Reduces bloating: Some studies suggest that mustard oil may help reduce bloating and gas.
Beyond its health benefits, mustard oil is also appreciated for its pungent flavour and high smoke point, making it a versatile cooking oil.
What is Mustard Oil?
Mustard oil is a type of vegetable oil extracted from the seeds of the mustard plant (Brassica species), which includes black mustard (Brassica nigra), brown mustard (Brassica juncea), and white mustard (Brassica alba). It is a popular oil in South Asia, particularly in Indian, Bangladeshi, and Nepali cuisines, where it is commonly used for cooking and flavouring dishes. Mustard oil is also used in other parts of the world for various medicinal, cosmetic, and even industrial purposes.
Key Characteristics:
- Smoke Point: Mustard oil has a high smoke point (around 250°C or 480°F), making it suitable for deep frying and high-heat cooking.
- Colour: Mustard oil has a distinct dark yellow to reddish-brown colour.
- Aroma: It has a pungent and sharp smell, similar to the mustard spice itself.
- Flavour: It has a strong, slightly spicy taste that adds a bold flavour to food.

Mustard oil is a good source of essential fatty acids, particularly oleic acid and erucic acid. These fatty acids have been linked to various health benefits, including:
- Cholesterol reduction: Mustard oil is rich in unsaturated fatty acids, particularly oleic acid, which has been shown to help lower LDL (“bad”) cholesterol levels. High LDL cholesterol levels are a risk factor for heart disease.
- Reduced heart disease risk: By lowering cholesterol levels, mustard oil can help reduce the risk of heart attack, stroke, and other cardiovascular diseases.
- Digestive health: mustard oil can help stimulate the secretion of digestive enzymes, which can aid in the breakdown of food and improve digestion.
- Reduces bloating: Some studies suggest that mustard oil may help reduce bloating and gas.
- Antioxidant properties: Mustard oil contains antioxidants, such as vitamin E, that can help protect cells from damage caused by free radicals. Free radicals are harmful molecules that can contribute to premature ageing and various health problems.
It is important to note that mustard oil is also a source of erucic acid, which can be harmful in high quantities. However, the erucic acid content in mustard oil is typically low enough to be safe for consumption.
How is Mustard Oil made? Step-by-Step Process
1. Seed Collection
- Mustard seeds (black, yellow, or white) are collected from mustard plants.
- Seeds should be clean, dry, and free of dust or dirt before processing.
2. Cleaning the Seeds
- The seeds are cleaned to remove impurities like dust, dirt, or small stones.
- This can be done manually or with the help of machines (seed cleaning machines or sieves).
3. Drying the Seeds
- After cleaning, the seeds are dried in the sun or in a dryer to reduce moisture content.
- This step ensures better oil yield during extraction.
4. Seed Cracking or Crushing
- The seeds are passed through rollers or crushers to break them into smaller pieces.
- This makes it easier to extract oil as it increases the surface area for pressing.
5. Conditioning (Heating)
- The crushed seeds are heated slightly to soften them and release the oil.
- This step can be done using steam or dry heat, typically in the range of 60°C to 75°C.
- Heating ensures a higher yield of oil.
6. Oil Extraction (Cold Press or Expeller Method)
- Cold Press Method: The crushed seeds are placed in a cold press machine where oil is extracted without using heat. This process preserves the natural flavour and nutrients of the mustard oil.
- Expeller Press Method: The seeds are fed into an expeller press machine, where they are subjected to high pressure to extract the oil. Some heat is generated due to friction, but the method is still considered a form of cold pressing if temperatures remain below 49°C.
- The oil extracted is typically filtered to remove impurities.
7. Oil Filtration
- The extracted oil contains seed particles and other impurities, which are filtered out using a fine cloth or a filtration machine.
- The filtered oil is then stored in a container.
8. Residue Cake Processing
- The residue left after oil extraction is known as mustard seed cake.
- This cake is either used as animal feed or as organic fertilizer in agriculture.
9. Oil Settling & Storage
- The filtered oil is allowed to settle for a few hours to let any remaining particles settle at the bottom.
- Afterwards, the oil is transferred to clean, dry containers for storage.
10. Bottling and Packaging
- Once settled, the mustard oil is bottled, labelled, and sealed.
- The oil should be stored in a cool, dark place to preserve its quality.
This process yields pure mustard oil that can be used for cooking, medicinal, and cosmetic purposes.
