In physics, the term moisture refers to water, an invisible, compressible, ponderable, odorless gas that is found in every part of the planet. It is a vital component in life as it transports nutrients and waste, and gives oxygen to living organisms.
A water molecule contains one atom of oxygen and two hydrogen atoms that have a small positive charge (d+) and two lone pairs of electrons with a negative charge (d-). These hydrogen atoms form a covalent bond with the oxygen atom to form a water molecule.
What is moisture value?
Moisture is a very important factor in the manufacture and handling of food products as it affects their texture, quality, safety, and shelf life. Moisture Meter can also affect the ability of a product to retain its color and maintain its shape.
The most common measurement for moisture content is to determine the amount of water in a sample and compare that to the total weight of all other solids in the sample. This can be done in a number of ways, and is often reported on a wet or dry basis.
However, this method is not as accurate as direct moisture measurement methods. This is because the mass of water must be maintained throughout the evaporation process, which can be difficult and time consuming in practice.
To improve the accuracy of moisture readings, a reference scale can be used to identify an oven-dry water activity level for the material being tested. Having this value as a baseline can reduce confusion and allow you to make more informed decisions during testing and inspections.
