What Are the Most Common Varieties of Canola/Rapeseed Oil?

The most common varieties available in the food manufacturing industry are:

  • Canola Oil (also known as Regular Canola Oil or Canola Salad Oil)

Canola Oil is often commonly known as regular Canola Oil or Canola Salad Oil. This oil is made from the seeds of a canola oil plant. Most canola crops today (about 90%) do use genetic modification. The oil is expelled using solvents (commonly Hexane) to remove the most oil possible. This is the majority of Canola Oil available in today’s market and it offers the lowest price point.

  • Expeller Pressed Canola Oil

Expeller Pressed Canola is an oil that is made from traditional canola seeds but is produced using expeller pressing methods. Instead of expelling the oil using solvents, the oil is pressed out using a mechanical press. No chemicals are used in the productions of this oil.

  • Non-GMO Expeller Pressed Canola Oil

Non-GMO Expeller Pressed Canola Oil is produced in much the same way that regular Expeller Pressed Canola Oil is. It is pressed using mechanical means and no chemicals are used. The major difference is that this oil is created from seeds that have been grown without the use of genetic modification.

  • Organic Canola Oil

Organic Canola Oil is the highest quality type of canola oil available. It is produced using expeller pressing methods and no chemicals are used. Besides, it is produced using canola seeds that have been grown organically. Because of the USDA organic national program regulations, these organic seeds are also Non-GMO.

What Are the Methods of Canola Oil & Rapeseed Oil Production?

Rapeseed oil production is obtained in two methods - by pressing or extraction. For each method, the seed must be fragmented and prepared for processing. Finally, it is refined using water precipitation and organic acid to remove gums and free fatty acids, filtering to remove color, and deodorizing using steam distillation. Canola/rapeseed at this point oil is ready to be packaged and sold as cooking oil, or further processed into a wide range of consumer and commercial products.

1. Pressing - mechanical fat extraction in a press. Chemicals are not used in the process. The seeds are crushed in a screw press, rubbed into a pulp and the extracted oil passes through filters, on which residues are retained. The oil obtained via this process is of high quality. Pressing can be done in two ways:

Cold method - oils obtained mechanically at a controlled temperature - cold-pressed oils - discharge temperature maintained at a level no higher than 50° C. The most expensive method of obtaining oils. The oil obtained is rich in unsaturated fatty acids, has an intense color and smell. Because it does not contain a preservative it should be quickly used up.

Hot method - involves the production of oil at a temperature of 160 - 200° The yield of seeds of oil plants doubles, but the unsaturated fatty acids are changed into unfavorable trans-isomers.

2. Chemical (extraction) - isolation of oil with chemical solvents (most often with hexane), while heating up to high temperatures (over 100° C). This is the most efficient and cheapest method of obtaining oil, however, it deprives the raw material of valuable nutrients and leaves traces of chemical solvent, therefore it is not recommended in food. Currently, extraction is more often preceded by pressing. After receiving the oil, the next stage is the refining or purification stage (it is not obligatory).

Quality Control/Certification

How Do You Store Canola Oil & Rapeseed Oil Properly?

1. Rapeseed and canola oil should have an acid value of at most 0.6% to 2.0%. Oils and fats spoil by readily becoming rancid aided by light, atmospheric oxygen, and moisture leading to changes in odor and taste. Subject to compliance with the appropriate temperature ranges, duration of storage is not a limiting factor as regards transport and storage life.

2. Normally, the oil does not need to be heated, since its solidification point is relatively low.

3. Rapeseed and Canola oil have no particular requirements as to storage climate conditions:

- Travel temperature (favorable temperature range): 15°C (12 to 24°C)

- Pumping temperature: approximately 15°C

- Solidification temperature: 0°C to -15°C

4. Under normal transport conditions, rapeseed and canola oil are liquid and therefore need not to be heated. In the solidification state, if the temperature rises during transportation, the oil has to be heated to achieve pump ability. Solidification temperatures are of considerable significance in the transportation of fatty oils and fats. The oil must remain liquid during loading, during transportation, and unloading.

Chill haze (separation) begins if cooling causes the temperature of the oil to approach solidification point, the oil becoming ointment-like and finally solid, such that it is no longer able to be pumped. Separation and the associated change in consistency from liquid to solid occur more readily upon cooling, the higher the solidification point. The oils must only be heated by a few degrees centigrade per day, otherwise, the risk of rancidity and other negative changes arises.
