Fragrant oil is a necessary kind of cooking flavoring in modern kitchen. Generally speaking, it is added as a cold or eating noodle and eating hot pot, which is used to add the aroma of food. A few drops of sesame oil before cooking can increase appetite. Then the length of the storage time and whether there is a shelf life of the problem, do you want to know, the long time will be expired? Below the saints and oil for everyone to answer one by one!
The small mill flavor oil is taken by the low temperature water generation method. As the production process of the small abrasive oil is kept to the greatest extent, its nutrient composition, especially the antioxidation sesamol, VE and so on, has a longer shelf life and longer flavor retention period.
Sesamol has a strong aromatic odor. In the process of production, sesamol is not easily destroyed and lost at low temperature. Therefore, it has high nutritional value and has a natural antioxidant effect on the fragrant oil. Therefore, the quality and retention period of sesame oil are longer.
As a result of the influence of high temperature and high pressure, the mechanism of sesamol and VE, which have the antioxidant effect, are more destroyed.
Some people say that true sesame oil does not oxidize, which is incorrect. Sesame oil is not easy to oxidize, but the oxidation process is relatively slow. This is because sesame oil contains a certain amount of vitamin E and sesame oil in sesame oil and other substances such as sesamol and sesamol forest. These substances have strong antioxidant capacity, so sesame oil is more suitable for storage than other vegetable oils.
Oil metamorphism is a gradual process, its gradual process can not be accurately judged by the nose and eyes, although in appearance (oil taste, color, etc.) can not see changes, but the quality and quality of the oil itself may have been deteriorated, it is possible to produce some harmful "compounds", so it is built. For health, it is better to choose the brand of regular manufacturers.
The essence of the oil is generally eighteen months, so the oil is used up in 1 and a half years, or the oil after the expired, there is a special flavor of stimulation, that is, the smell of the so-called "Kazakh" smell. It indicates that the sesame oil has been decomposed and decomposed, causing toxicity. Consumption of "Rana" oil may cause poisoning.
Storage method of sesame oil: under normal circumstances, cover the lid of sesame oil and store it in a cool, dry and dark place.
Now know that the oil will not expire, if the fragrant oil is placed too long, it will lead to expiry, but the reasonable storage method of fragrant oil will keep the oil for a long time.
