Recovery, yields for methanethiol from an aqueous model system and a soy protein concentrate (SPC) aqueous slurry determined with this method ranged from 97 to 107% and from 103 to 121%, respectively. The methanethiol content of two commercial SPCs and two commercial soy protein isolate (SPI) samples, on a dry basis, ranged from 835 to 1190 times greater than the odor threshold for methanethiol.

Nitric acid - Wikipedia

Nitric acid, (H NO 3), also known as aqua fortis (Latin for "strong water") and spirit of niter, is a highly corrosive mineral acid.. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available ,nitric acid, has a concentration of 68% in water.
