Compound produced by dehydration of a carbonic acid. General formula is R--C--O--C--R. Chemical compound that reacts with water to form an acid and are usually oxides of nonmetallic elements.

Anhydrides are generally more reactive than their corresponding acids because they are able to react with water to form their corresponding acid.

What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support

Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry.

As these quality standards become stricter, beverage producers are increasingly called upon to get products to market faster using fewer resources, while simultaneously managing ingredient quality, and ultimately, risk.
