The Three Main Types of Mustard Oil


Mustard oil is extracted from the seeds of the mustard plant, primarily from black, brown, and white varieties. The oil’s type is defined by its extraction method and chemical profile.


  • Cold-Pressed Mustard Oil (Kachi Ghani): Extracted using traditional presses at low temperatures. It preserves natural nutrients, making it ideal for cooking, hair care, and massage.
  • Mustard Essential Oil: Steam-distilled from mustard seeds. It is rich in allyl isothiocyanate, a compound known for its potent antimicrobial properties, and is for external use only.
  • Refined Mustard Oil: Extracted using chemical solvents and then refined to reduce its strong flavor and erucic acid content.

1. Cold-Pressed Mustard Oil (Kachi Ghani)


This traditional oil is a staple in Indian and South Asian households due to its high smoke point, strong aroma, and nutrient retention.


Key Features:


  • Rich in monounsaturated fats and omega-3 fatty acids, beneficial for heart health.
  • Naturally high in allyl isothiocyanate, offering antimicrobial and anti-inflammatory benefits.
  • Retains natural nutrients like vitamins A, D, E, and K.
  • Features a robust flavor and a bold golden color.
  • Its high smoke point (around 250°C / 482°F) makes it suitable for high-heat cooking.

Common Uses:


Stat: Used in over 70% of Indian households, according to a FSSAI Consumer Report (2021).


2. Mustard Essential Oil (Steam-Distilled)


Derived from steam-distilling mustard seeds, this highly concentrated and volatile oil is potent and intended for external use only. In the United States, the FDA has approved it for topical applications like massage and aromatherapy, but not for consumption.


Key Characteristics:


  • High concentration of allyl isothiocyanate.
  • Strong antimicrobial, antifungal, and anti-inflammatory properties.
  • Often diluted with a carrier oil for joint pain relief and scalp stimulation.
  • Labeled "For External Use Only" by the FDA due to its potency and high erucic acid levels.

Common Uses:


  • Diluted with carrier oils for massage to relieve arthritis.
  • Stimulates the scalp to encourage hair growth.
  • Used in aromatherapy for sinus relief.
  • Helps treat fungal infections and minor wounds.

3. Refined Mustard Seed Oil


Refined mustard oil undergoes chemical processing to create a milder, more neutral product by reducing its strong flavor and erucic acid content.


Attributes:


  • Lower in flavor and nutrients compared to cold-pressed oil.
  • Stable at high temperatures, with a high smoke point.
  • A milder taste makes it suitable for non-traditional or Western cooking.
  • Lacks the robust nutritional profile of cold-pressed oil.
  • Often used in blended vegetable oils or mustard-based salad dressings.

Regulatory Status Worldwide


The approval of mustard oil for consumption varies globally, largely due to its erucic acid content.


  • India & Pakistan: All types are permitted, with cold-pressed being the most popular.
  • United States: Banned for cooking/consumption due to erucic acid concerns. It is sold with a label stating "For External Use Only."
  • EU, Canada & Australia: Allow the sale of mustard oil for consumption, but with regulations on erucic acid levels.

Tip: Always check labels for terms like "organic," "cold-pressed," or "for external use only" to ensure you're buying the correct product for your needs.


How to Choose the Right Mustard Oil


To select a high-quality product, look for clear labeling, food-grade certifications, and transparent sourcing. Depending on your needs, choose the appropriate type:


Use Case Best Option
Traditional Indian/Asian Cooking Cold-Pressed Mustard Oil
Hair Care & Body Massage Cold-Pressed or Diluted Essential Oil

What’s the difference between cold-pressed and refined mustard oil?


Cold-Pressed: Retains more nutrients and has a strong, pungent flavor. Best for traditional recipes and wellness uses.

Refined: Has a neutral taste and aroma, making it better suited for modern or Western cooking styles.

Why is mustard oil banned for cooking in some countries?

Some countries, like the U.S., restrict mustard oil for cooking due to its natural erucic acid content, which studies have suggested may pose health risks in very high amounts. There, it is sold only for external use.


Which mustard oil is good for heart health?

Cold-pressed mustard oil is considered beneficial for heart health when used in moderation. It is rich in monounsaturated fats (approx. 60%), omega-3 fatty acids, and antioxidants, which support cardiovascular function.
