Description
12-Methyltridecanal, also known as 12-MT aldehyde or isotetradecan-1-al, belongs to the class of organic compounds known as fatty aldehydes. These are long chain aldehydes with a chain of at least 12 carbon atoms. Thus, 12-methyltridecanal is considered to be a fatty aldehyde lipid molecule. 12-Methyltridecanal is considered to be a practically insoluble (in water) and relatively neutral molecule. 12-Methyltridecanal has been primarily detected in urine. Within the cell, 12-methyltridecanal is primarily located in the membrane (predicted from logP) and cytoplasm. 12-Methyltridecanal has a broth, cooked, and cooked meat taste.
Chemical Properties
12-Methyltridecanal has an aroma characteristic of stewed beef (meaty, tallow)
Occurrence
Stated to be of natural origin; has not been reported in any food items by TNO (Nutrition and Food Research)
(TNO, 2000)
Uses
12-Methyltridecanal (MT) was found in microorganisms samples isolated from beef.
Application
12-Methyltridecanal can be used in the field of analytical chemistry as a standard for the calibration of detection instruments, such as gas chromatography-mass spectrometry (GC-MS), aimed at identifying and quantifying volatile compounds within complex mixtures. Its role in the synthesis of surface-active agents is another area of application, contributing to research on substances that alter the surface tension of liquids.
Biosynthesis
It is believed that 12-methyltridecanal is preferentially a constituent of ruminants, possibly being synthesized by the bacteria in the rumen, andincorporated in the plasmalogens.
Aroma threshold values
Detection at 0.0001 ppm (water)
