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) smelling tallowy, beef-like was formed from plasmalogens when beef was boiled. It was found in microorganisms samples isolated from beef.
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)
