说明

一般說明

Citric acid is a weak organic acid naturally found in citrus fruits. It is widely used as an acidulant, preservative, and flavoring agent in the food and pharmaceutical industries.​ In pharmaceutical formulations, citric acid acts as a buffering agent to control pH and enhance the stability of active ingredients. The USP Citric Acid standard ensures the consistency and quality of citric acid used in these applications.The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.
