Sesame oil is available naturally from sesame seeds. In terms of nutritional values, the oil contains very similar substances as those originally found in its seed form. It has calcium, copper, zinc, iron, magnesium, and more. This oil is commercially available, but you can apply the following extraction methods step-by-step to create homemade sesame oil.
1. Toast the seeds
Put the sesame seeds on a frying pan, and then toast them conventionally on a stove. You can also place the seeds on a baking sheet then put it in an oven (350 degrees F). Remove the seeds from heat after 5 minutes, stir them, and apply heat again for 10 to 20 minutes.
You need to watch the baking process closely, so you can immediately recognize when the seeds become light brown in color and they produce nutty aroma. At this conditions, remove the baking seed or pan. Take the seeds the place them on another plate, so it cools down more quickly.
2. Add sunflower seed oil
The extraction process of sesame seeds oil requires sunflower seeds. Commonly, every ¼ cup of toasted sesame seeds should be mixed with 1 cup of sunflower seed oil. Make the mixture in a pan, and heat it again on a stove with medium heat for several minutes. If you cannot find sunflower seed oil, you can also use peanut oil.
Remove the pan from the stove then pour the mixture into a blender. Blend it until the seeds become small pieces. Allow the blended mixture to sit for approximately two hours.
If you mix sesame seeds with peanut oil, you need to blend the mixture until it becomes a paste-like form. It will only take approximately 45 minutes before the mixture produces sesame oil.
4. Strain off the oil

Pour the mixture into an empty bowl covered with clean cheesecloth. This method will prevent the small pieces of seeds from entering the bowl. You will not need to perform this method it you use peanut oil. After 45 minutes, the blended mixture of sesame seeds with peanut oil will naturally settle a layer of oil at the top. You need to scoop it carefully by using a spoon.
The extraction process by using peanut oil takes less time, but it can be difficult to scoop the oil. With sunflower seed oil, the extraction takes more time because you need to leave the mixture for two hours before straining it off.
5. Keep it safe
Store the extracted oil in an airtight container. Place the container in a refrigerator, so it lasts for long period.
