Is the odor in the factory air of Hubei Xinshengyuan Bioengineering Co., Ltd. harmful?

There are two chemical methods of peptide chain hydrolysis, heating hydrolysis with sodium hydroxide solution or heating hydrolysis with dilute sulfuric acid. If sodium hydroxide is used, it will be hydrolyzed into sodium amino acid, so it should be hydrolyzed with dilute sulfuric acid. Dilute sulfuric acid may be reduced to sulfurous acid and decomposed into sulfur dioxide by heating, which has a pungent smell. Sulfur dioxide is toxic to human body.
