Wood-Pressed Groundnut Oil: Why It Deserves a Place in Your Everyday Kitchen

Have you ever noticed how a simple change in cooking oil can transform the aroma and flavour of your favourite dish?

Think about a freshly prepared dosa, crispy vegetable poriyal, or a traditional South Indian curry.

The ingredients matter. The spices matter. But there's another ingredient that quietly influences the taste of every meal — the cooking oil.

For generations, groundnut oil, also known as Kadalai Ennai in Tamil, has been a familiar ingredient in Indian kitchens.

Today, as more families explore traditional ingredients and cooking methods, wood-pressed groundnut oil is receiving renewed attention.

But what makes it special? And why should you consider including it in your everyday cooking?

Let's explore.

1. What Is Wood-Pressed Groundnut Oil?

Wood-pressed groundnut oil is extracted from groundnuts, also known as peanuts, through a traditional mechanical pressing method.

In Tamil Nadu, this method is commonly associated with the Marachekku wooden oil press.

During extraction, mechanical pressure releases oil from the groundnuts.

Depending on the processing method, the extracted oil may be allowed to settle or filtered before bottling.

Unlike extensively refined oils, traditionally pressed groundnut oil can retain more of the natural nutty aroma and characteristic flavour of the original groundnuts.

This makes it a distinctive choice for people who enjoy traditional Indian cooking.

At Thuuya Oils, our appreciation for Marachekku extraction reflects our commitment to celebrating traditional ingredients and their place in everyday life.

2. Why Groundnut Oil Has Been a Favourite in Indian Kitchens

Groundnut oil has a long history in Indian cooking, particularly in regions where groundnuts are widely cultivated and consumed.

Its familiar nutty taste complements a variety of traditional dishes.

From daily vegetable preparations to festive snacks, groundnut oil can add a distinctive character to food.

Its versatility makes it useful for several cooking methods, including sautéing, shallow frying and selected frying applications.

More importantly, groundnut oil is an ingredient many families already associate with the comforting flavours of home.

Sometimes, the secret behind a memorable meal isn't a complicated recipe. It's the familiar ingredients used to prepare it.

3. What Makes Wood-Pressed Groundnut Oil Different?

The key difference lies in the processing method.

Traditional wood pressing relies on mechanical pressure to extract oil, whereas refined groundnut oil undergoes additional processing to reduce substances such as pigments, free fatty acids and odour-producing compounds.

These differences can influence the finished oil's appearance, aroma and flavour.

Feature	Wood-Pressed Groundnut Oil	Refined Groundnut Oil
Extraction	Traditional mechanical pressing	Pressing or solvent extraction followed by refining
Processing	Generally fewer processing stages	Additional refining stages
Aroma	Often distinctly nutty	Usually milder
Flavour	Retains more groundnut character	More neutral
Appearance	May vary naturally	Typically more consistent
Cooking applications	Depends on oil quality and temperature	Often used for general cooking and frying

Both types can have a place in the kitchen when they meet applicable food safety standards.

Wood pressing is not automatically proof of greater nutritional value or safety.

4. Understanding the Nutritional Composition of Groundnut Oil

Groundnut oil contains a combination of different fatty acids, primarily:

Monounsaturated fats (MUFA): Groundnut oil is generally rich in oleic acid, a monounsaturated fatty acid.

Polyunsaturated fats (PUFA): It also contains linoleic acid, an essential omega-6 fatty acid.

Saturated fats: These are present in smaller proportions than the unsaturated fats in typical groundnut oil.

The precise composition varies according to the peanut variety and growing conditions.

Groundnut oil also naturally contains compounds such as tocopherols, which are forms of vitamin E. Their levels can vary with processing and storage.

Unsaturated fats can be useful components of a balanced diet, particularly when replacing some saturated fats.

However, groundnut oil remains calorie-dense and should be used in appropriate quantities.

No single cooking oil can guarantee good health independently of overall dietary habits.

5. Is Wood-Pressed Groundnut Oil Suitable for Everyday Cooking?

Yes, edible wood-pressed groundnut oil can be used for a variety of everyday cooking applications, provided it is handled appropriately.

Its nutty flavour makes it an appealing choice for traditional Indian recipes.

Here are a few ways to use it.

For Vegetable Poriyal

A small amount of groundnut oil can provide a pleasant flavour when sautéing onions, curry leaves, mustard seeds and vegetables.

For Dosa and Adai

Brushing a suitable quantity of oil around the edges of a dosa or adai can help achieve a desirable texture and flavour.

For Traditional Curries

Groundnut oil can complement the spices, tamarind and aromatics commonly used in South Indian gravies.

For Shallow Frying

Groundnut oil can also be used for shallow frying when the temperature is appropriately controlled.

For Traditional Snacks

Groundnut oil has long been used for preparing savoury Indian snacks.

For higher-temperature frying, suitability depends on the specific oil's quality, degree of refining and smoke point. Do not assume that an unrefined wood-pressed oil has the same smoke point as refined peanut oil.

6. Why Groundnut Selection Matters

Just as good coconut oil begins with suitable copra, good groundnut oil begins with properly selected groundnuts.

The quality of peanuts can be influenced by:

• Maturity and condition of the groundnuts.

• Moisture content.

• Storage conditions.

• Exposure to pests or contamination.

• Handling before extraction.

Poor storage conditions may encourage mould growth.

Certain moulds can produce aflatoxins, harmful contaminants that require appropriate prevention and testing.

This is why responsible groundnut oil manufacturing must consider raw material handling, hygienic processing and relevant quality-control standards.

A traditional extraction method cannot compensate for contaminated raw materials.

The quality of groundnut oil begins long before the pressing process.

7. Does Wood-Pressed Groundnut Oil Have a Strong Smell?

One of the appealing characteristics of traditionally pressed groundnut oil is its naturally nutty aroma.

However, the intensity can vary depending on the raw material, any pre-treatment, extraction conditions and storage.

A pleasant groundnut aroma is different from an unpleasant rancid smell.

Oil that has deteriorated may develop undesirable odours or flavours.

While aroma can help you notice potential deterioration, smell alone cannot verify purity or food safety.

8. How to Store Wood-Pressed Groundnut Oil Properly

Good storage practices are essential for preserving the flavour and quality of groundnut oil.

Keep the bottle tightly closed. Reduce unnecessary exposure to air and moisture.

Store away from direct sunlight. Light and heat can accelerate undesirable changes in edible oils.

Avoid keeping the bottle near the stove. Prolonged exposure to high temperatures can affect its freshness.

Use clean, dry utensils. Avoid introducing water or food particles into the container.

Follow the best-before date. Always observe the product's labelled storage instructions.

Also avoid repeatedly heating cooking oil or reusing oil that has become excessively dark, smoky or degraded.

9. Groundnut Oil vs Coconut Oil: Which One Should You Choose?

Both are popular traditional cooking oils, but their fatty acid compositions and flavours differ.

Characteristic	Groundnut Oil	Coconut Oil
Dominant fats	Mostly unsaturated	Mostly saturated
Flavour	Nutty	Characteristic coconut
Everyday use	Sautéing, curries and selected frying	Traditional coconut-based dishes and cooking
Appearance at cooler temperatures	Usually remains liquid	May solidify
Best suited for	Dishes that complement a nutty flavour	Dishes where coconut flavour is desired

Neither oil needs to be used for every dish.

Selecting oils based on their fatty acid composition, cooking suitability and flavour can help create variety in the kitchen.

10. Is Wood-Pressed Groundnut Oil Safe for Everyone?

Groundnuts are a recognised food allergen.

This is an important consideration when choosing groundnut oil.

Highly refined peanut oil generally contains very little residual peanut protein, but unrefined and cold-pressed peanut oils may retain allergenic proteins.

People with peanut allergies should avoid wood-pressed groundnut oil unless their allergy specialist has specifically advised otherwise.

Always check the product label and relevant allergen information.
