The best mustard oil is one that undergoes minimal processing while preserving the seed’s natural nutritional components. Refined, expeller extracted, cold pressed and kachi ghani mustard oils are produced using different extraction methods. Understanding these processes helps consumers choose the oil that best matches their cooking preferences and quality expectations.

Choosing the right mustard oil depends on understanding how it is extracted rather than relying only on marketing claims.

There are four common categories of mustard oil available in India:

• Refined Mustard Oil
• Expeller Extracted Mustard Oil
• Cold Pressed Mustard Oil
• Kachi Ghani Mustard Oil

Each follows a different manufacturing process involving different levels of processing, temperature and filtration.

This article explains every extraction method in simple language and also introduces Pure Tatva’s Zero Heat Extraction System.

Buying mustard oil should be simple.

But today’s market is filled with confusing labels.

Cold Pressed

Kachi Ghani

Wood Pressed

Refined

Expeller Extracted

Every brand claims to sell the healthiest oil.

So naturally, one question arises.

Which mustard oil is actually best for cooking?

The answer lies not only in the oil itself but also in how that oil is extracted.

Most consumers compare oils based on advertisements, packaging or price.

Very few compare them based on their manufacturing process.

Yet the manufacturing process determines how the oil is produced and how much processing it undergoes before reaching your kitchen.

In this guide, we’ll explain the four most common types of mustard oil available in India.

We’ll compare

• Refined Mustard Oil
• Expeller Mustard Oil
• Cold Pressed Mustard Oil
• Traditional Kachi Ghani Mustard Oil

You’ll also learn how Pure Tatva’s Zero Heat Extraction System differs from conventional extraction methods.

By the end of this article, you’ll have a much clearer understanding of the different manufacturing processes used for mustard oil.

Why Understanding Oil Extraction Matters

When people buy vegetables, fruits or grains, they often pay attention to freshness.

Surprisingly, very few people ask a similar question about cooking oil.

How was this oil extracted?

This question matters because different extraction methods involve different manufacturing processes.

Some methods include multiple refining stages.

Others rely mainly on mechanical extraction.

Some traditional processes differ from modern industrial production.

Understanding these differences allows consumers to make informed decisions instead of depending only on marketing terms.

Types of Mustard Oil Available in India

The Indian market mainly offers four categories of mustard oil.

• Refined Mustard Oil
• Expeller Extracted Mustard Oil
• Cold Pressed Mustard Oil
• Kachi Ghani Mustard Oil

Let’s understand each one individually.

What is Refined Mustard Oil?

Refined mustard oil is produced through a series of industrial processing steps intended to produce a uniform oil suitable for commercial distribution.

While exact manufacturing methods may vary between producers, the process generally involves multiple stages after the initial extraction of oil from mustard seeds.

These stages are designed to remove impurities, odour, colour and other naturally occurring components to achieve a consistent finished product.

How Refined Mustard Oil is Made

Although processes differ among manufacturers, refined mustard oil typically involves several steps, such as:

Step 1

Mustard seeds are cleaned.

Step 2

The seeds are mechanically crushed to release oil.

Step 3

Some industrial processes use food-grade extraction aids or solvents to improve oil recovery. One commonly referenced solvent in industrial edible oil extraction is hexane, though processing methods vary by manufacturer and regulations.

Step 4

The crude oil then undergoes multiple refining stages, which may include:

• Degumming
• Neutralization
• Bleaching
• Deodorization
• Filtration

Each step aims to improve the oil’s appearance, stability, flavour, or shelf life.

Why is Refined Oil Processed?

The refining process is primarily intended to:

• Improve colour consistency
• Reduce odour
• Increase shelf stability
• Produce a standardized commercial product
• Remove suspended impurities

Different manufacturers may use different refining conditions depending on their production systems.

Advantages of Refined Mustard Oil

• Consistent appearance
• Longer shelf life
• Widely available
• Uniform taste
• Stable commercial production

Considerations Before Choosing Refined Oil

Consumers who prefer minimally processed foods often compare refined oils with less processed alternatives such as cold pressed or traditional oils.

Choosing the right oil depends on individual preferences, cooking habits and the level of processing one is comfortable with.

What is Expeller Extracted Mustard Oil?

Expeller extraction is one of the most common mechanical methods used to extract oil from seeds.

In this method, mustard seeds are compressed using a continuously rotating screw inside an expeller machine.

The pressure forces oil out of the seeds while the remaining solid material exits separately.

Unlike refined oil, expeller extraction is primarily a mechanical process.

However, operating conditions such as pressure, speed and temperature can vary significantly depending on the equipment and manufacturer.

How Expeller Mustard Oil is Produced

A typical expeller extraction process involves:

• Cleaning the seeds
• Feeding them into a screw press
• Mechanical compression
• Oil collection
• Filtration or settling before packaging

Some production systems may also condition the seeds before extraction depending on manufacturing requirements.

Advantages of Expeller Extraction

• Mechanical extraction
• High production capacity
• Common industrial process
• Suitable for commercial manufacturing

Things Consumers Should Know

Not every expeller operates under identical conditions.

Factors such as machine design, operating temperature, seed preparation and filtration methods differ across manufacturers.

For this reason, consumers should ask manufacturers about their actual extraction process instead of relying only on product labels.

What is Cold Pressed Mustard Oil?

Cold pressed mustard oil has become one of the fastest-growing categories in India’s edible oil market.

Consumers generally associate the term “cold pressed” with minimal processing and lower extraction temperatures compared to conventional industrial extraction methods.

However, one important question is often overlooked.

Does every oil labelled “cold pressed” actually remain cold throughout the extraction process?

The answer depends on how the oil is produced.

The term “cold pressed” is widely used in the industry, but actual operating temperatures can vary based on:

• Machine design
• Pressing speed
• Friction generated during extraction
• Seed preparation
• Production capacity

This is why understanding the manufacturing process is often more valuable than relying solely on the label.

How Cold Pressed Mustard Oil is Made

In most cold pressed systems:

• Mustard seeds are cleaned.
• The seeds are fed into a mechanical press.
• Oil is extracted using mechanical pressure.
• The oil is filtered before packaging.

Unlike refined oil, cold pressed oils generally undergo fewer processing steps.

However, extraction conditions can vary significantly between manufacturers.

Is Every Cold Pressed Oil Actually Extracted at Low Temperature?

This is one of the most common questions consumers ask.

The reality is that “cold pressed” is a broad manufacturing term, and different machines generate different amounts of friction during operation.

In some systems, friction during continuous pressing may increase the temperature of the oil.

The actual extraction temperature depends on several factors, including:

• Press design
• Screw speed
• Pressure
• Production rate
• Cooling mechanism
• Duration of operation

For this reason, consumers who want greater transparency may choose to ask manufacturers how their extraction temperature is monitored and controlled.

What is Kachi Ghani Mustard Oil?

Kachi Ghani is one of India’s oldest and most traditional methods of extracting mustard oil.

The name “Kachi Ghani” refers to the traditional pressing technique rather than a specific nutritional profile.

For generations, Kachi Ghani mustard oil has been widely used in Indian households because it typically involves less industrial processing than refined oils.

How Kachi Ghani Mustard Oil is Produced

A typical Kachi Ghani process includes:

• Cleaning mustard seeds
• Conditioning the seeds
• Mechanical pressing using a traditional ghani or screw press
• Collecting the extracted oil
• Filtration before packaging

Although the process is traditional, manufacturing practices may differ from one producer to another.

Why is Water Sometimes Added During Traditional Kachi Ghani Extraction?

Some traditional extraction systems add a controlled amount of water during processing.

The exact purpose and quantity vary depending on the manufacturer and equipment used.

This step may help facilitate extraction under certain traditional processing methods.

Not every manufacturer follows the same practice, which is why consumers should understand the specific process used by the brand they choose.

Advantages of Traditional Kachi Ghani Oil

Many consumers appreciate Kachi Ghani mustard oil because it is associated with:

• Traditional extraction methods
• Minimal industrial refining
• Characteristic mustard aroma
• Familiar cooking experience

Actual product characteristics depend on the manufacturer’s production process.

Refined vs Expeller vs Cold Pressed vs Kachi Ghani Mustard Oil

Understanding the extraction process makes it easier to compare these oils.

So, Which Mustard Oil Should You Choose?

So, Which Mustard Oil Should You Choose?

There is no single answer that suits every consumer.

The best choice depends on your priorities.

If you value:

• Minimal processing
• Transparency in manufacturing
• Understanding how your oil is produced

then it makes sense to ask detailed questions before buying.

Instead of asking only,

“Which brand is best?”

consider asking,

“How exactly is this oil extracted?”

The extraction process tells you much more than the label alone.

How Pure Tatva’s Zero Heat Extraction System is Different

At Pure Tatva, our journey began with a simple belief:

If temperature, pressure, and processing influence food, then the extraction process deserves as much attention as the ingredients themselves.

This led us to develop our Zero Heat Extraction System, designed to extract oil without intentional heating during the extraction stage.

Before extraction, excess moisture is carefully managed according to our process requirements.

The oil is then extracted using a controlled mechanical process intended to minimise friction-generated heat during extraction.

Instead of relying on conventional processing methods, we focus on:

• Careful seed preparation
• Controlled extraction conditions
• Double filtration
• Hygienic manufacturing practices
• Batch-level process monitoring

The objective is to produce an oil with minimal processing while maintaining transparency throughout the manufacturing process.

Why Transparency Matters

Today’s consumers want more than a label.

They want to know:

• How was the oil extracted?
• What manufacturing process was used?
• Was unnecessary processing avoided?
• Can the manufacturer explain the complete process?

At Pure Tatva, we believe consumers deserve those answers.

That is why we regularly invite customers, doctors, nutrition professionals and food enthusiasts to visit our facility and see the process for themselves.
