What You Need to Know About Sulphites - Unlock Food

A sulphite sensitivity is when the body reacts to consuming sulphites. Sulphite sensitive people may have a similar reaction as those with a food allergy. Sulphites can trigger asthma and symptoms of an anaphylactic reaction. Many people who have asthma may also have a sulphite sensitivity. An allergist can confirm sulphite sensitivity.

How to Calculate PPM | Sciencing

Parts per million or PPM is a dimensionless measure of the concentration of one substance mixed in with another. For example, the amount of lead in a sample of water, or the amount of CO 2 in the atmosphere. It's essentially like a percentage, which you could analogously refer to as "parts per hundred," but PPM is better suited to substances in much smaller concentrations.
