Is Glycine and Its Sodium Salt vegetarian?

E640 covers glycine and its sodium salt (sodium glycinate), the simplest amino acid used as a flavour modifier and nutrient supplement. Glycine can be produced synthetically (from chloroacetic acid) or derived from protein hydrolysates of animal or plant origin. It is the smallest and simplest amino acid.

An ingredient is considered vegetarian if it avoids components derived from killing an animal.
