【Q&A Question 013】May 03, 2016: What is the smoke point? What factors are related to it? The answer key will be available after responding; scoring is based on addressing the key points. The maximum smokeless flame height of jet fuel combustion is related to the unsaturated components.
The smoke point refers to the temperature at which smoking is observed in a fat or oil when it is heated under non-ventilated conditions. It is related to odor, color, transparency, moisture and volatiles, impurities, acid value, peroxide value, and unsaponifiables.
The smoke point refers to the temperature at which smoking is observed in a fat or oil when it is heated under non-ventilated conditions. Quality control is usually carried out based on standards such as odor, color, transparency, moisture and volatiles, impurities, acid value, peroxide value, and unsaponifiable matter
Answer: The smoke point refers to the temperature at which smoking is observed in a fat or oil when it is heated under non-ventilated conditions. Among the lipid components, free fatty acids and oxidation products are the main factors affecting the smoke point, while phospholipids, monoglycerides, and antioxidants such as BHA, BHT, and TBHQ all have varying degrees of influence on the smoke point.

The smoke point is primarily related to the structure of the raw materials. Generally speaking, lower smoke points are associated with poor-quality raw materials; impurities in the raw materials also lead to a decrease in smoke points. A qualified cooking oil should have a smoke point of 300 degrees Celsius; however, if the quality is poor, the smoke point may drop to 270 degrees, at which point black smoke will begin to appear.

The maximum smokeless flame height of jet fuel combustion is related to the unsaturated components.
It refers to the maximum height of a smokeless flame produced when kerosene and jet fuel used for lighting burn under specified test conditions. Black smoke will be produced above this height. The smoke point is an important indicator for kerosene-based products; a high value for the height of the smokeless flame indicates a low content of aromatics, resulting in cleaner combustion. The smoke point is expressed in mm, with typical values ranging from 22 to 28 mm; it is a specification parameter used to control the carbon deposition tendency of aviation fuel.

Smoke point: It refers to the temperature at which smoking is observed in a fat or oil when it is heated in a non-ventilated environment. Impurities in oils and fats, the types and amounts of lipids, as well as external factors are important factors that affect the smoke point of oils and fats
It refers to the temperature at which smoking is observed in the sample when heating the fat under a non-ventilated condition. Aromatic content
