L-proline is one of the important amino acids for the synthesis of human protein, an important raw material for amino acid infusion, and a major intermediate for the synthesis of first-line antihypertensive drugs such as Captopril and enalapril, which has been widely used in food, medicine and other industries. Usage: As a nutritional supplement and flavoring agent, it undergoes amino acid carbonyl reaction with sugar by co heating, which can generate special aroma substances |
