SESAME OIL PROPERTIES
What is the sesame oil?
Sesame oil is an oil extracted from the seeds of the sesame plant (Sesamum indicum). There are different types of oil derived from sesame seed types and the method of production. Among them, the main are:
- Cold pressed sesame oil: it has a pale yellow color. It is the preferred sesame oil for natural food stores in the Western countries, since it has all its properties.
- Toasted sesame oil: It has a dark brown color. It is produced from roasted seeds. It is the most widely used in East Asia.
It has an intense aroma and flavor. Some Japanese sesame oils are particularly dark, almost black. This is why you can only add a few drops of them to meals, so as taste and smell becomes not to much prominent.

- Pressure sesame oil: It has a yellow color. It is generally obtained by non-cold pressure, and it is usually filtered twice. It is the oil used in India for both food and massages or the one that Ayurvedic medicine uses. Its aroma and taste are less intense. Many of its properties are lost in the refining process.
The major saturated fatty acids of sesame oil are palmítico, palmitoleic and stearic acid. Oleic acid makes up most of its monounsaturated fatty acids, whereas linoleic acid (omega-6) is the major polyunsaturated fatty acid. It also contains about 1% linolenic acid (omega-3).
Besides fatty acids, sesame oil is rich in vitamin E, which provides antioxidant properties.
USES OF SESAME OIL
Traditional use of sesame oil
Traditionally, sesame oil has been widely used by many cultures, as described by Joseph Oriol in his "Dictionary of commercial industrial and agricultural matters" (1851)
Culinary uses of sesame oil
Despite the enormous amount of linoleic acid (omega-6), sesame oil is a good oil to use it in the kitchen because it resists high temperatures. In addition, due to its richness in vitamin E, and natural preservatives sesamol and sesamin, it is an oil that lasts long and does not become rancid over time. Normally, only monounsaturated oils such as olive oil, often resist the test of time when exposed to external agents such as light or air.
Pressed sesame oil is light in color and resists higher temperatures, making it useful for frying, while the darker sesame oil made from toasted seeds requires lower temperatures because it is more likely to burn and produce smoke. Pressure oil can be used to fry or to cook vegetables. Cold-pressed sesame oil is best used for cold dishes, like salads.
Since sesame oil is very tasty, many excellent dishes are prepared with it. In Indian cuisine, especially in southern states, people make widespread use of such an oil, as Mediterranean cuisine does from olive oil.
Quite commonly used in Chinese and Korean cuisine. (More information on Sesame Recipes in the listing above)

Recommended consumption of sesame oil
In Europe, sesame oil is consumed very little in the kitchen. In the United States, it is becoming very important as a cooking oil. For this reason, the American Heart Association recommends that this type of oil should not exceed 10% of total calorie intake per person per day.
The reason is that there is a large imbalance in its composition in terms of essential fatty acids. For proper functioning of the body is has been established the appropriate relationship between essential fatty acids omega-3 and omega-6.
The proper ratio stands at 4:1, that's to say, four parts of omega-6 to one part of omega-3. The superiority of omega-6 in the sesame oil, according to experts, can sometimes be responsible for diseases such as, heart attack, depression, diabetes. etc. Therefore, it is recommended a very moderate intake of this type of oil (a few drops in salads or vegetables per day)
When eating, it is better to take it crude. If used in cooked dishes, is added after the end of cooking to prevent heat to destroy its properties. This type of oil for a heavier consumption should be diluted with other vegetable oils such as sunflower or soy oil (6 to ten parts of sunflower and soybean for a part of sesame oil)
