Cold Pressed and Refined Oils: Your Guide to Choosing the Right Oil for Your Needs

The extraction methods of vegetable oils affect their properties and uses as well as their health benefits. The vegetable oil industry is a wide and diverse industry. It includes products that are used as foodstuffs or ingredients that are mainly used in cosmetics and medicines. Understanding the differences between refined oils and cold-pressed oils is crucial for purchasing professionals, production experts, R&D teams, and dealers who aim to choose the right oil for their specific needs. This article covers the processing techniques, the characteristics of each type, and their different applications.

1. What are cold pressed oils?

Cold pressed oils are also known as raw or virgin oils. They are extracted by mechanical methods without the use of heat and in a way that does not result in high heat generation without the use of chemicals or solvents. Mechanical compression methods are used to extract oil from seeds, nuts, or fruits. This technique preserves the natural flavor, aroma and nutritional properties of the oil.

The main steps in processing:

1. Cleaning and drying: Raw materials (seeds, nuts or fruits) are cleaned and dried to remove moisture.
2. Era: A mechanical machine presses the raw material, releasing the oil from the seed or fruit. This process takes place at low temperatures (usually below 50°C) to preserve nutrients and natural antioxidants.
3. Nomination: The oil is filtered to remove solid particles, but retains its natural color, smell and taste.

Properties of cold-pressed oils:

• Special flavor and smell: It retains the flavor and aroma of the natural seeds or fruits extracted from them, making them ideal for use in salads, sauces and fine products.
• Nutrient safety: Because no heat or chemicals are used, beneficial compounds such as vitamins (vitamin E), antioxidants, and essential fatty acids are retained.
• Shorter shelf life: The natural ingredients of the oil (such as polyunsaturated fats) are more susceptible to oxidation, resulting in a shorter shelf life.
• Low smoke point: This limits their use in high-temperature cooking methods.
• The percentage of free fatty acids: a maximum of 2% as a percentage of fatty acids?
• The peroxide number is 15 mg oxygen equivalent/ kg of oil or fat.
• Iron element: a maximum of 5 mg/kg.
• Copper element: max 0.4 mg/kg

Common examples:

• extra virgin olive oil
• cold pressed coconut oil
• flaxseed oil
• avocado oil

2. What are refined oils?

Refined oils undergo a series of mechanical and chemical processes to remove impurities, free fatty acids, phospholipids, gums, waxes, colors and scents. This approach aims to produce a consistent, stable and long-lived product. However, chemical processes and treatments are not consistent in refining all types of oils. The main steps in refining include the following:

The main steps in processing:

1. Remove the glue: Remove phospholipids and other viscous substances using water, acid, enzymes, or silica hydrogel.
2. Equation with alkali: Free fatty acids are neutralized or treated using an alkali, often sodium hydroxide.
3. Whitening: The oil is filtered through active bleaching dust or activated carbon to remove or lighten the color and reduce or eliminate impurities.
4. Remove odors: The steam distillation process is used to remove volatile compounds that cause strange odors or flavors.

Properties of refined oils:

• Neutral flavor and smell: Perfect for use in cooking where a neutral taste is preferred.
• CLEAR APPEARANCE: The bleaching process removes pigments such as chlorophyll and carotenoids.
• High smoke point: This makes it suitable for high-temperature cooking methods such as frying, roasting, and baking.
• LONGER STORAGE LIFE: Removing impurities increases the shelf life of the product and reduces the risk of rancidity.
• The percentage of free fatty acids: a maximum of 0.2% as a percentage of fatty acids?
• The peroxide number has a maximum value of 10 mg oxygen equipment/kg of oil or fat.
• Iron element: a maximum of 5 mg/kg.
• Copper element: max 0.4 mg/kg

 Common examples:

• soybean oil
• canola oil
• sunflower oil
• palm oil

4. How to choose the right oil for your uses

The choice of refined oils or cold-pressed oils depends on the intended use and the desired properties.

Here's an overview of the apps that are right for each type.

When do we use refined oils?

• Cooking and frying: The high smoke points of refined oils are perfect for frying, baking, and roasting.
• COSMETICS AND SKINCARE: The neutral smell and clear appearance make it suitable for lotions, creams and cosmetics.
• Industrial applications: Refined oils are used in soap making, biofuel production, and as a key ingredient in many industrial products.

When do we use cold pressed oils?

• Dietary uses (raw consumption): Perfect for seasoning salads, dressings and final oils for fine meals.
• Health and wellness products: Used in supplements and health products.
• Personal care: Cold-pressed oils are used in skin and hair care products because they retain natural nutrients.

5. Market trends and consumer demand

Consumer preferences have led to the use of cold-pressed oils as they have a good reputation among the consumer, but their high prices affect consumer decisions according to their economic situation. In contrast, refined oils continue to be in demand in industrial applications, such as food production, cosmetic industries, and food services.

6. Summary

Both refined oils and cold-pressed oils have unique properties and diverse applications. Refined oils provide consistency and long life, while cold-pressed oils provide natural flavor and health benefits. Understanding the differences between processing methods can lead to better purchasing decisions and improved product development.
