From Groundnut to Bottle at RJS: The Journey of Cold-Pressed Groundnut Oil

Have you ever wondered what happens before a bottle of groundnut oil reaches your kitchen?

The journey begins long before the oil is ready for cooking. It starts with agricultural raw materials and continues through inspection, cleaning, mechanical extraction, settling, quality checks and packaging.

Every stage has a purpose in preparing the finished product.

At RJS Healthy Foods, we believe customers should understand not only the oil they purchase but also the process behind it.

In this article, let's follow the journey of groundnut oil at RJS—from the selection of raw groundnuts to the finished bottle.

1. The Journey Begins With Groundnuts

Every bottle of groundnut oil begins with its primary raw material: groundnuts.

The condition of these groundnuts matters because agricultural produce can vary depending on variety, growing conditions, harvesting, drying and storage.

Before the groundnuts enter production, their suitability needs to be assessed.

Raw material selection is an important starting point because the extraction process cannot compensate for every problem that may exist in unsuitable raw materials.

At RJS, attention to the incoming raw material forms part of our approach to oil production.

2. Inspecting the Incoming Raw Materials

Once groundnuts arrive at the mill, the next step is to assess their condition.

A batch may contain a mixture of suitable material, damaged groundnuts and unwanted foreign matter.

The inspection process can help identify concerns such as:

• Visible stones and soil

• Dust and plant debris

• Damaged or discoloured groundnuts

• Signs of unsuitable storage

• Other material requiring further assessment

The aim is to understand the condition of the raw material before it moves to the next stage.

Inspection is important, but visual appearance alone cannot establish the complete quality or safety of a batch.

3. Sampling and Moisture Assessment

A single handful of groundnuts may not represent an entire delivery.

Representative sampling helps provide a more useful picture of the incoming batch. Samples can be examined for visible impurities and other relevant characteristics.

Moisture assessment is another important part of raw material evaluation.

Excess moisture can increase the risk of deterioration during storage and may affect processing suitability.

RJS's described raw material workflow includes sampling and moisture assessment alongside visual inspection and other relevant quality checks.

These steps help support a more informed decision before production begins.

4. Cleaning the Groundnuts

Before pressing, groundnuts need to be prepared appropriately.

Cleaning helps remove unwanted physical material such as stones, soil, dust and plant debris.

This step supports cleaner handling and helps protect production equipment from foreign objects.

The cleaning method depends on the condition of the raw material and the equipment available.

At RJS, visible impurity checks form part of raw material preparation before extraction.

Cleaning is an important step, but it does not replace other quality controls or appropriate testing where required.

5. Mechanical Pressing: Turning Groundnuts Into Oil

After the necessary inspection and preparation, the groundnuts move to the extraction stage.

Cold-pressed groundnut oil is obtained primarily through mechanical pressing.

During this process, pressure is applied to the prepared groundnut material, releasing oil that can then be collected.

The process also produces groundnut oil cake, the solid material left after much of the oil has been extracted.

Oil yield can vary according to the groundnut variety, raw material condition, moisture, preparation and equipment operating conditions.

This is why every stage before pressing matters.

6. Managing Temperature During Extraction

The term cold-pressed generally refers to mechanical extraction carried out with limited heat exposure compared with processes involving more intensive heating or refining.

However, the actual temperature during pressing can vary depending on the equipment, raw material and operating conditions.

RJS has described an approach that aims to keep groundnut and sesame oil processing below 50°C.

Temperature management is part of the extraction process, and actual operating conditions should be monitored appropriately.

Cold-pressed describes the extraction method; it does not automatically guarantee purity, safety or superior nutritional value.

7. Settling the Extracted Groundnut Oil

Once the oil has been extracted, it may contain fine suspended particles from the raw material.

Settling allows some of these particles to gradually move towards the bottom of a suitable container.

Over time, the upper portion of the oil may become clearer as heavier particles settle.

RJS's described process includes allowing extracted oil to settle in sunlight for approximately 7–14 days as part of its oil-handling approach.

The actual duration can vary depending on the oil and processing conditions.

Settling helps clarify the oil, but it is not a substitute for appropriate quality and safety checks.

8. Quality Checks Before Bottling

Before the oil is packaged, the finished product needs to be handled and assessed appropriately.

Depending on the product specifications and applicable requirements, quality checks may cover relevant characteristics such as:

• Appearance and clarity

• Aroma

• Signs of deterioration

• Applicable quality and safety parameters

• Suitability for packaging

No single visual characteristic can establish the complete quality of groundnut oil.

A clear appearance does not automatically prove purity, just as slight cloudiness does not automatically indicate poor quality.

At RJS, quality assessment forms part of the wider process from raw material selection to the finished product.

9. Filling and Packaging the Oil

After the required processing and checks, the oil is prepared for packaging.

Packaging helps protect the oil during storage, transportation and everyday use.

Before a bottle is dispatched, the relevant packaging and labelling requirements should be addressed.

Customers can also check the product label for:

• Product name and ingredient information

• Manufacturer details

• Batch information

• Manufacturing or packing date

• Best-before information

• Storage instructions

A properly sealed package and clear label help customers understand the product they are purchasing.

10. From the RJS Mill to Your Kitchen

Once packaged, the finished product can move into storage, distribution and delivery.

The journey from groundnut to bottle involves several connected stages:

Raw Material Selection → Inspection and Sampling → Moisture Assessment → Cleaning → Mechanical Pressing → Settling → Quality Checks → Packaging → Distribution

Each stage contributes to the wider manufacturing process.

The final bottle represents more than the extraction step alone. It is the result of raw material handling, processing, packaging and the decisions made along the way.

For customers, understanding this journey can make it easier to ask informed questions about the products they choose.

11. Why We Believe in Explaining the Process

At RJS Healthy Foods, our connection with food production is rooted in agricultural raw materials and traditional oil-making practices.

We believe that customers should be able to understand the process behind the products they bring home.

That means explaining the different stages of manufacturing rather than relying only on the appearance of the finished oil.

Our approach focuses on the journey from raw material selection to the finished bottle, with attention to inspection, preparation, extraction, handling and relevant quality checks.

Transparency also means being clear about what each stage can and cannot establish. No single step guarantees every aspect of product quality.
