What are Cold Pressed Oil?

Oils which are used for everyday cooking and other uses are extracted from seeds, fruits, vegetables, and nuts. The way the oil is extracted directly affects the taste of the oil and its nutrient content.

What are Cold Pressed Oil?

Cold-pressed is a technique in which the fiber is separated from a particular food item without using any amount of heat. This helps preserve the nutritive value and make the food taste better. The technique helps retain the aroma and nutritional value of the food, making it an ideal choice for cooking.

Cold Press Process

In cold-pressing oil extraction, the seed or nut are crushed and forced out of the oil. The presses come in different sizes from small size to be used at home to large sizes to be used commercially.

There is a cylinder in which the seeds are dropped. The cylinder contains rotating screws which grind and crushes the seeds until the oil is extracted from them. There are small holes in the bottom of the cylinder through which the oil escapes into the collection container.

A little heat is generated when the screws break down the seeds but it’s not enough to damage the oil.

Cooking with cold-pressed oil enhances the flavor but can be tricky to cook. These oils do not react well to heat which is why they are extracted with low-heat technique. The oils containing mostly unsaturated fat, like sesame oil, degrade when heated. These oils breakdown when used in sauté or stir-fry. They work well when drizzled over finished products.

If the oils contain saturated fats such as olive oil, they can handle high temperatures of sautéing and grilling.
