News from the world of technology. Yesterday I found in the store a nipple with a proud sticker"WITHOUT SODRY GLUTAMATE". I suspect that it was purified from glutamate by mass spectrometry methods or by enrichment centrifuges. Or how do you, biochemists, divide amino acids?

yyy: With MS you will be depriving a bite of the nipple of glutamate until it becomes blue. In an enrichment factory, in the style of centrifugal uranium enrichment.
Homogenize nakher, collect soluble proteins, isolate insoluble detergent, reset THU, hydrolysate into individual aminoxylates, divide into HPLC. And then modern biochemistry breeds hands, because it is not possible to collect the chicken back.
