Moisture content is a critical factor to consider in the food industry. The amount of water in a product affects the product’s
texture, shelf life, ease of processing, and cost to produce
. Snack foods, baked goods, pet food, and dried goods are just a few examples of products that are vulnerable to moisture content issues like these. In many cases, an easy loss-on-drying test will allow you to monitor the moisture content of these products.

The answer to the question, “How Long Does a Water Activity Test Take?” is, as with most testing questions, “it depends.” Some water activity meters promise a test completed in a very short time; some in as little as five minutes. This time is an arbitrary selection that may or may not produce a satisfactory result.

When we first started measuring moisture with Karl Fischer,I was instructed in the complex chemical reactions involved. I was also was told that the process was skittish.

A question we get a lot is:
“How do I determine the moisture in my product?
Of course, the answer is often “it depends”, and the method does depend on the chemical and physical composition of the product. There are several methods used to determine moisture content: Loss-on-Drying (also known as Weight Loss), Karl Fischer, NIR, and Radio Frequency.

Last week, as I was reflecting on a recent moisture content problem, I recalled our series “Loss-on Drying and Other Moisture Mysteries.” In that series I examined moisture chemistry in products. However, I did little to define moisture content.

“Why are my Moisture Test results inconsistent?”
That is an issue for many of you who test for moisture. We discussed the complexities and multiplicity of issues involved with moisture content determination in our “Loss-on Drying Moisture Analysis and other Moisture Mysteries” series.
In addition to intrinsic properties of test samples that may adversely affect moisture testing systems, automatic equipment parameter set-up, operator oversights and sample handling contribute to seemingly intractable moisture test result inaccuracies.

In my previous missive about Loss-On drying, we discussed Vapor Pressure -- because logically it was next. As we continue to explore moisture, we learn how vital vapor pressure is when regarding the quirky issues of free and bound water.

As part of our line of moisture measurement instruments, we produce a Karl Fischer titrator, We call it the Aquapal. The heart of the Aquapal is a series sophisticated electronics. Its purpose is to measure small amounts of moisture.
