Groundnut Oil vs Refined Oil — A Scientific Look at Stability and Nutrition

Walk down any supermarket aisle and you’ll see two kinds of oils — one gleamingly clear, odourless, uniform; the other golden, aromatic, slightly cloudy. One is refined, the other cold-pressed.

But behind that difference in appearance lies an even deeper contrast — in nutrition, safety, and heart health.

So how exactly does cold-pressed groundnut oil like Kedia Pavitra’s outperform refined oil? Let’s take a closer look — through the lens of science, not marketing.

The Extraction Process — Nature vs Mechanics

Refined oils undergo multiple stages: solvent extraction (using hexane), degumming, neutralisation, bleaching, and deodorisation at temperatures exceeding 200 °C. While this extends shelf life, it destroys natural antioxidants and converts delicate PUFA into trans fats.

Cold-pressed groundnut oil, however, is pressed at low temperature (< 60 °C) and filtered naturally. This preserves tocopherols (Vitamin E), polyphenols, and aroma compounds.

Nutrient Density and Fatty Acid Profile

Groundnut oil offers a naturally balanced mix of MUFA (50%), PUFA (30%), and saturated fat (20%). These ratios align closely with the ICMR-NIN-recommended fatty-acid distribution for Indian diets.

During refining, oxidation, and hydrogenation reduce MUFA and PUFA levels and can form trace trans fats. Cold-pressed oils maintain their native structure, ensuring better absorption and metabolic support.

Oxidative Stability — The Real Measure of Purity

Oils break down when exposed to heat, light, or air — a process called oxidative rancidity. Cold-pressed groundnut oil resists this naturally due to its high MUFA content and Vitamin E. Refined oils need synthetic antioxidants like BHA or TBHQ to delay spoilage.

Studies show that cold-pressed peanut oil has higher oxidative stability than refined peanut oil when heated repeatedly for frying.

In short, nature’s own preservatives work better than lab-made ones.

Flavour and Bio-Integrity

Refined oils are neutral because they’ve been stripped of aroma compounds. Cold-pressed groundnut oil retains its signature nutty flavour and golden tone, a marker of unbroken phytonutrients.

The FSSAI’s Clean Label Initiative encourages consumers to choose minimally processed oils to reduce chemical intake.

Health Impact — Refined vs Cold-Pressed

• Refined oil: Higher oxidation, lower antioxidant value, possible trace trans fats.
• Cold-pressed groundnut oil: Higher HDL support, stable cholesterol levels, natural antimicrobial compounds.

Clinical trials found that participants using unrefined peanut oil for 12 weeks showed a 7–10 % increase in HDL and reduced inflammatory markers compared to those using refined blends.

Environmental and Economic Footprint

Refining requires large industrial energy inputs and chemical waste treatment. Cold-pressing is low-energy, small-batch, and farmer-friendly — a circular economy model that champions by sourcing directly from growers in Gujarat and Rajasthan.

Taste Test — Authenticity in Every Drop

In Kedia Pavitra’s oil, you’ll see a gentle cloudiness — proof of minimal filtration and unrefined goodness. The aroma is fresh, nutty, real. Refined oil may look clearer, but clarity isn’t cleanliness — it’s absence. Absence of life.

Final Pour

In the end, the choice between refined and cold-pressed is really a choice between speed and sincerity. Refining gives you shelf life; cold-pressing gives you real life.

When you choose Cold-Pressed Groundnut Oil, you choose stability, flavour, and nutrition the way nature intended — no filters needed.

Because clarity in oil isn’t about how it looks.

It’s about how honestly it’s made.
