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.
Heat of Vaporization
The amount of heat required to vaporize one gram of a liquid at its boiling point with no change in temperature. Usually expressed in J/g. The molar heat of vaporization is the amount of heat required to vaporize one mole of liquid at its boiling point with no change in temperature and usually expressed ion kJ/mol.
Molecular Weight
The mass of one molecule of a nonionic substance in atomic mass units.
Turning iron nail into copper nail
This simple chemical experiment shows the so-called process of copper plating of metal products. Copper has the ability to deposit on a metal surface.
Molecular Formula
Formula that indicates the actual number of atoms present in a molecule of a molecular substance.
Valence Bond Theory
Assumes that covalent bonds are formed when atomic orbitals on different atoms overlap and the electrons are shared.
Boiling Point Elevation
The increase in the boiling point of a solvent caused by the dissolution of a nonvolatile solute.
Saccharic
of or derived from saccharin or a saccharine substance.
Hydrogenation
The reaction in which hydrogen adds across a double or triple bond.
