How Does The Cold-Pressing Process Preserve Nutrients In Oils?

Have you ever wondered why cold-pressed oils have become so popular? 

It's not just about the delicious taste they bring to your food (although that’s definitely a perk). 

Cold-pressed oils are packed with health benefits, thanks to the way they're extracted.

At Gramiyaa, we believe our traditional methods, though simple are most efficient. That's why we use the cold-pressing method to produce our high-quality oils. 

But how exactly does this process preserve the goodness within? Let's dive deeper into the science behind cold-pressing and explore how it safeguards the valuable nutrients present in these oils.

First, let’s take a look at the downside of refined oil extraction

Oil extraction methods that use heat and chemicals can significantly affect the nutritional value of the final product. Here are some of the cons:

  • High temperatures: Mass-manufactured extraction often involves high heat, sometimes exceeding 200°C (392°F). This intense heat can damage delicate nutrients like vitamins, antioxidants, and essential fatty acids. These vital components are highly sensitive to temperature and can break down or lose their potency when exposed to excessive heat.

  • Nutrient degradation: Vitamins, particularly Vitamin E, are susceptible to heat degradation. This essential vitamin plays a vital role in maintaining a healthy immune system and protecting cells from damage. High temperatures during extraction can reduce the Vitamin E content in the oil.

  • Chemical residues: Some mass-manufactured extraction methods use chemical solvents to increase oil yield. While these solvents are typically removed during processing, there's a risk of residual traces remaining in the final oil. These residues can raise concerns about safety and potential health implications.

The health benefits of cold-pressed oil

As compared to mass-manufactured methods, cold-pressing is a gentle and natural process that protects the source material's inherent goodness. Let's explore why cold-pressed oil is better:

  • Minimal heat: The defining feature of cold-pressing is the use of minimal to no heat. Typically, the heat remains below room temperature (plus ~10 to 15 degrees higher) throughout the process. This low-temperature environment protects the delicate nutrients from any degradation because of heat.

  • Mechanical pressure: Instead of relying on heat, cold-pressing uses mechanical pressure to extract the oil. The seeds, nuts, or fruits are crushed using a hydraulic press. This physical force separates the oil from the solid matter, making sure that the damage to the delicate ingredients is minimal.

  • Preserved phytonutrients: Cold-pressing preserves a wider range of beneficial phytonutrients naturally present in the source material. These phytonutrients include plant-based compounds like phenols and sterols, which have been linked to various health benefits, including anti-inflammatory and antioxidant properties.

  • Minimal processing: Cold-pressed oils are minimally processed and undergo no post-processing after extraction. This means they retain their natural colour, flavor, aroma, and a higher concentration of naturally occurring antioxidants compared to their refined counterparts.

That’s not all, though. Cold-pressed oils have other benefits too

Unlike heavily processed oils, cold-pressed oils retain their distinct and often subtle flavours. This translates to a more enjoyable culinary experience. Let’s explore why is cold pressed oil better for cooking:

  • Different flavours: Each cold-pressed oil has its unique flavor profile. For instance, cold-pressed groundnut oil has a mild, nutty flavor that complements various dishes. On the other hand, cold-pressed sesame oil has a richer, nuttier aroma, perfect for adding depth to stir-fries or finishing touches on salads.

  • Enhanced taste of food: Cold-pressed oils don't overpower the natural flavors of your ingredients. Instead, they subtly enhance them. A drizzle of cold-pressed coconut oil can add a hint of sweetness to your curries, while a touch of cold-pressed mustard oil can bring a pleasant pungency to your dals (lentils).

  • Unlocking Culinary Creativity: The diverse flavor profiles of cold-pressed oils open doors to creativity in cooking. Experimenting with different oils allows you to explore new taste combinations and elevate your dishes to new heights.

  • Freshness You Can Taste: The minimal processing involved in cold-pressing translates to a fresher taste compared to heavily refined oils. This freshness adds another layer of enjoyment to your food.

Choosing the right cold-pressed oil for your needs

With a growing variety of cold-pressed oils available, selecting the right one for your needs can feel overwhelming. Here are some key factors to consider:

  • Smoke Point: The smoke point refers to the temperature at which the oil starts to smoke and break down. This is a crucial factor when choosing an oil for a specific cooking method. For high-heat cooking like deep-frying, you'll need an oil with a high smoke point, such as cold-pressed sunflower oil or mustard oil. Conversely, for sauteing or drizzling, oils with a lower smoke point, like groundnut oil or sesame oil, are suitable.

  • Flavor Preference: As mentioned earlier, each cold-pressed oil has its distinct flavor profile. Consider the overall taste you're aiming for in your dish. If you want a subtle nutty flavor, choose groundnut oil. Craving a hint of sweetness? Coconut oil might be your perfect match. Experiment and discover which flavors complement your dishes best.

  • Nutritional Profile: While all cold-pressed oils offer health benefits, they vary slightly in their nutritional content. For example, cold-pressed flaxseed oil is rich in omega-3 fatty acids, while cold-pressed avocado oil is a good source of healthy monounsaturated fats.

  • Cuisine Inspiration: Different culinary regions often have their preferred cold-pressed oils. In India, mustard oil is a staple in Bengali cuisine, while coconut oil reigns supreme in South Indian and Southeast Asian cooking. Explore refined uses of cold-pressed oils for culinary inspiration.

Moderation is Key: Remember, even though cold-pressed oils are a healthier alternative to refined oils, they are still calorie-dense. Two teaspoons per person per meal is a good rule of thumb to enjoy the flavor and health benefits without exceeding your calorie intake.
