In recent years, there has been a growing shift toward healthier cooking practices, with many people opting for oils that retain their natural nutrients and flavors. One such oil that has gained popularity for its health benefits and natural extraction method is cold pressed oil. But what exactly is cold pressed oil, and how does it differ from other types of oils like refined or expeller machine oils?
We’ll explore the key characteristics of cold pressed oils and why they are considered a healthier and more nutritious option.
What is Cold Pressed Oil?
Cold pressed oil is a type of oil extracted from seeds, nuts, through a mechanical pressing method (ideally wood as it's bad conductor of heat) that involves no heat or chemicals. Unlike refined oils, which undergo high-heat processing and sometimes chemical treatments, cold pressed oils are made by crushing the oilseeds at room temperature. This low-temperature extraction process ensures that the natural nutrients, flavors, and aromas of the oil are preserved, making it a healthier and more flavorful choice for cooking.
The wood press oil technique is traditional and thus best when compared with other methods. The process is slow and methodical, and since it doesn’t involve any external heat, the oil retains a higher level of its natural compounds, including vitamins, minerals, and antioxidants. As a result, cold-pressed oils are often considered more nutritious than refined oils.
How oil is extracted by Wood pressed method?
The process of extracting cold pressed oil begins by cleaning and grinding the seeds or nuts to break them down into fine particles forming a paste. Further it releases the oil and oilcake separately in wooden or Lakdi ghani. The key to this process is that the oil is extracted without heat, which means that the oil maintains its full nutrient profile.
The oil extracted through this method is unrefined, which means it contains more of the plant’s beneficial compounds, including essential fatty acids, vitamins (like Vitamin E), and antioxidants. Cold pressed oils are typically cloudy in appearance due to the presence of these natural compounds, and they often have a more robust, distinctive flavor compared to refined oils.
What Makes Cold-Pressed Oils Different?
Several factors distinguish cold-pressed oils from other types of oils, particularly refined and expeller-pressed oils. Here are some of the key differences:
1. Nutrient Retention
Cold-pressed oils retain a higher amount of nutrients compared to refined oils, which are stripped of their natural goodness during the high-heat refining process. The lack of heat during extraction helps preserve essential nutrients like vitamin E, polyphenols, antioxidants, and omega-3 and omega-6 fatty acids, all of which are beneficial for heart health, skin, and overall well-being.
2. No Chemicals or Heat
Refined oils often undergo chemical processes such as bleaching and deodorizing, as well as high-heat treatments, which can damage the delicate compounds found in the oil. Cold-pressed oils, on the other hand, are free from chemicals and retain their natural flavors and nutrients. The absence of heat also means that the oil maintains a richer taste and aroma, which is ideal for enhancing the flavor of your dishes.
3. Flavor and Aroma
Because cold-pressed oils retain the natural essence of the seeds or fruits from which they are derived, they tend to have a more intense and distinct flavor compared to refined oils. For example, cold pressed groundnut oil often has a nutty flavor & tastes good, and cold-pressed coconut oil retains a coconut flavor. These oils can enhance the taste of foods, particularly in dressings, dips, or light sautéing.
4. Higher Quality
Cold-pressed oils are often considered higher quality because of the careful extraction process. Since they are minimally processed, these oils are considered a more natural and wholesome option compared to highly refined oils, which may be subjected to processes that reduce their overall quality and nutritional value.
5. Environmental Benefits
Cold pressing is a traditional method of extraction that requires less energy and fewer resources compared to the large-scale industrial processes used to make refined oils. As the cold-pressing process is gentler, it is more eco-friendly, making cold-pressed oils a sustainable choice for environmentally-conscious consumers.
Common Types of Cold-Pressed Oils
Many types of oils can be cold-pressed, each offering unique health benefits and culinary applications. Some of the most common cold-pressed oils include:
- Groundnut Oil: Known for its heart-healthy monounsaturated fats, rich source of fat
- Coconut Oil: High in medium-chain triglycerides (MCTs), which are beneficial for brain health and weight management.
- Sesame Oil: Packed with antioxidants and known for its rich, nutty flavor, commonly used in Asian cuisine, even used for massaging tissues
- Flaxseed Oil: Rich in Omega-3 fatty acids, particularly beneficial for heart health and reducing inflammation. It's used for massaging and is good for bone health.
- Mustard Oil: Ideal for cooking Indian cuisines, it's pungent flavor makes it taste good in food, even used for massaging tissues.
- Almond Oil: Ideal for using it on hair or skin for the natural glow, can be used on Salad for best weight management.
Benefits of Cold-Pressed Oils
Cold-pressed oils provide numerous health benefits, thanks to their high nutrient content and minimal processing. Here are some of the advantages of incorporating cold-pressed oils into your diet:
- Heart Health: Wood pressed oils are rich in healthy fats that can lower bad cholesterol levels and support overall heart health.
- Anti-inflammatory Properties: The antioxidants in cold-pressed oils help reduce inflammation in the body, which can lower the risk of chronic diseases like arthritis.
- Skin and Hair Care: Cold-pressed oils, like coconut, almond, flax seed and sesame oils, can be used topically to moisturize the skin and hair, offering natural hydration and nourishment.
- Weight Management: Some cold-pressed oils, such as coconut oil, contain MCTs, which have been shown to aid in weight loss by increasing metabolism and fat burning.
Conclusion
Cold-pressed oils are a natural and healthier option for cooking, offering superior nutritional value, flavor, and aroma compared to refined oils. Their extraction method ensures that they retain vital nutrients and antioxidants that are often lost in the refining process. By choosing cold-pressed oils for your cooking needs, you can enjoy the full health benefits that come from consuming oils in their purest, most natural form. Whether you're drizzling sesame or almond oil on a salad or using groundnut oil for cooking, cold-pressed oils provide both health benefits and a delicious taste that enhances your meals
