Healthy Life Oil | What are the advantages of sesame oil and how to choose it?

Sesame oil is the most commonly used sesame oil, and in some places it is also referred to as sesame oil. In addition to containing about 15% saturated fatty acids, 39% oleic acid and 45% linoleic acid, as well as biologically active substances such as sterols, triterpenes, tocopherols, sesame oil also contains characteristic lignan substances such as sesamin, sesamolin, and sesamol. Sesamin has a variety of physiological functions. It can inhibit the absorption of cholesterol in the small intestine and hinder the synthesis of cholesterol in the liver, and has the effect of lowering serum cholesterol; it can promote the metabolism of ethanol and enhance detoxification activity; it also has antioxidant activity in the body, improves immunity, and has anti-hypertension effects. Therefore, sesame oil is generally loved by people.

The unique flavor produced by roasting sesame seeds is the main characteristic of sesame oil. As the roasting temperature and roasting time increase, the color of hot-pressed sesame oil deepens, the peroxide value increases, and the acid value decreases. The antioxidant substances produced after roasting make the thermal oxidation resistance of sesame oil stronger and the aroma is greatly enhanced. Low-temperature pressed sesame oil is squeezed out with the help of external force at a temperature below 85°C, which retains more active nutrients.

Sesame oil is also commonly known as sesame oil. It is mainly divided into four types according to different production processes: the one produced by water substitution is called sesame small mill sesame oil, the one produced by oil press is called sesame sesame oil, the one produced by extraction and refining is called sesame oil, and the one produced by low temperature pressing is called fragrant sesame oil.

Sesame oil is made from roasted sesame seeds and stone-ground, then produced by water substitution. It not only has a long-lasting fragrance, but also has strong antioxidant properties. Sesame oil is made from roasted sesame seeds using pressing or filtration techniques. It has a strong fragrance and strong antioxidant properties, but the high-temperature roasting process is prone to produce harmful substances such as benzo[a]pyrene. Extracted sesame oil is a finished sesame oil made by refining the crude sesame oil obtained by the extraction process. It has a lighter color and a light fragrance. Low-temperature pressed sesame oil is a pressed oil squeezed out with the help of external force at a temperature below 85°C. It retains more active ingredients in sesame, but the oil has slightly poor oxidative stability and a short shelf life.

Since different users may have different preferences for the intensity of sesame oil flavor, the selection of sesame oil should be based on the characteristics of sesame oil produced by different processes, and combined with the user's own needs and preferences. The quality control of sesame oil can refer to the quality indicators of "Sesame Oil" (GB/T 8233-2018). Sesame oil is divided into two levels: primary and secondary. Its color should be orange-yellow, orange-red to brown-red, with a strong sesame oil-specific aroma and taste, good taste and no odor. Primary sesame oil is clear and transparent, and secondary sesame oil allows slight turbidity.
