Application of rapeseed oil
Let’s take a look at the uses of rapeseed oil;
Cooking: Rapeseed oil is useful for frying, grilling, frying eggs and other fried foods. It is also used in baked goods such as cookies and cakes.
Food industry: Rapeseed seeds are used in the food industry to make bread, margarine, canned food and ready meals.
Other industries: Rapeseed oil is used in soap making, plastics, rubber industries and as a lubricant in industrial machinery.
Nutritional value of canola oil
Canola oil is a good source of vitamins E and K. Each tablespoon (15 mL) of canola oil contains the following:
- Calories: 124
Vitamin E: 16% DV
Vitamin K: 8% DV - Fatty Acid Composition
- Canola oil is considered one of the healthiest oils due to its low levels of saturated fat. Here’s a breakdown of the fatty acids in canola oil:
- Saturated fat: 7% Monounsaturated fat: 64% Polyunsaturated fat: 28%
Rapeseed oil production process
We will continue with the journey of rapeseed seeds to become golden oil. The journey of these tiny seeds from the fields to becoming pure oil is a fascinating and informative process, which we will briefly discuss below:
1. Harvesting: During the harvest season, rapeseed seeds are collected when they have turned dark brown and their pods have dried.
2. Cleaning: In this stage, impurities such as soil, stones, leaves and other excess materials are removed from the seeds to protect the quality of the final oil.
3. Drying and grinding: The moisture content of the seeds must reach the optimum level for oil extraction. Therefore, the seeds are dried with special machines. If necessary, they are converted into smaller pieces to increase their contact surface with the solvent and to make the oil extraction process more efficient.
4. Oil extraction with a rapeseed oil press: At this stage, two main methods are used to extract oil from rapeseed seeds:
Cold pressing: In this method, the oil is separated from the seeds by applying mechanical pressure to them. This method is the best and healthiest method of extracting rapeseed oil.
Solvent extraction: In this method, solvents such as hexane are used to dissolve the oil in the seeds. Then, the solvent is separated from the oil by distillation methods and the crude oil is extracted.
5. Oil purification: If necessary, to remove some impurities, the obtained oil is purified and deodorized.
6. Packaging and supply: The refined oil is packaged in special containers and supplied to the market.

Factors affecting the amount of oil extracted from canola seeds
Several factors affect the amount of oil extracted from canola seeds, which can be divided into the following categories:
Factors related to the seed
Factors related to canola seeds include the type of seed, growing conditions, harvest time, and moisture. Choosing the right type of canola seed can affect the amount of oil in the seeds. Factors such as weather, soil, fertilization, and pests can also affect the quality and quantity of canola seed oil.
Also, canola seeds must be fully ripe at the time of harvest to have the maximum amount of oil, and the moisture content of the seeds must also be at an optimal level, as high moisture can cause the seeds to rot and reduce the amount of extracted oil.

Factors Related to the Extraction Process
Factors related to the process of extracting oil from canola seeds include the extraction method, process conditions, and equipment quality. In this process, various extraction methods such as cold pressing and hot pressing are used, each of which has its own advantages and disadvantages and can affect the amount of oil extracted.
Also, parameters such as temperature, pressure and process time can also affect the amount of oil extracted. The use of high-quality equipment can also help extract more oil from the seeds and has a significant impact on improving the performance of the process.
