Understanding the Difference between Cold-pressed and Commercial Vegetable Refining Processes

Understanding the Difference between Cold-pressed and Commercial Vegetable Refining Processes

Vegetable oils are an important part of all types of foods and delicacies. It canned food, food for feeding, or margarine. On the industrial application front, vegetable oils are found almost everywhere right from the production of detergents, paints, varnishes, and fatty acids to pharmaceuticals and cosmetics.

What are vegetable oils?

Vegetable oils or vegetable fats are extracted from various types of seeds and parts of fruits making use of extremely sophisticated equipment for oil extraction. Just like fats that are obtain from animal sources, vegetable oils are also a blend of triglycerides.

Cocoa butter, soybean oil, and grape seed oil are the finest examples of natural fats obtain from seeds. The  rice bran oil, olive oil, and palm oils can consider the examples of fats that are obtain from parts of fruits. In a nutshell, vegetable oils can be refer to as vegetable fats that remain in a liquid state at room temperature.

Components of edible oils

Vegetable oils extraction and process in a facility equipped with ultramodern equipment for oil extraction have various types of components. Different oils have different percentages of the same constituents. Many of these components interact differently with air and oxygen and form a different effect and efficiency. The antioxidants present in these vegetable oils resist oxidation to help preserve the quality of the oil for longer durations. The pro-oxidants in them promote oxidation so during the refining procedure, this aspect of vegetable oils is also well take care of.

The details of antioxidants and pro-oxidants are below mention

Antioxidants that resist rancidity in the vegetable oils include the following:

  • Tocopherols (vitamin E)
  • Carotenoids

Pro-oxidants that aid rancidity in the vegetable oils are:

  • Water
  • Transition metals (iron, copper)
  • Polar lipids
  • Chlorophyll

Commercial edible oil processing

The commercial edible oil processing that takes place in a facility equipped with extremely sophisticated equipment for oil extraction and provided by the top oil refinery and deodorization plant manufacturer in India is often different from the one that is carried out or adopted by the small-scale vegetable oil manufacturers.

Low-scale units generally go for cold-press processes and the oil produce and manufacture this way is use more for medical applications rather than eating purposes. On the other hand, commercial oil refining is completely a chemical-based process that produces vegetable oils in bulk for large-scale commercial use.

Some important facts about commercial and low-scale cold-pressed processes:

  • Small-scale processing results in more oil left in the meal in comparison to the chemical processing
  • Typically, the oil in the meal from small-scale processing ranges from 8 to 15%. But in commercial processing the percentage is less than 1%.
  • Oil pressed at a temperature below 49°C (120°F) is familiar as “cold-pressed” oil.

Concluding Remarks

Mectech is one of the leading companies in India manufacturing. And supplying equipment for oil extraction as well as deodorization plant. With more than 40 years of rich experience within the industry under the able leadership of Mr. Ishwar Sahai – the founding father and the Managing Director of the company, Mectech has emerged as a leading brand, not just in India, but globally because of continuous technological innovation.
