Combating Moisture

Supported by Trouw Nutrition’s extensive historical data, our experts will collaborate with you to determine the target, the acceptable range and varying levels of heat applied to the sample in effort to provide you with the moisture testing most suitable to your unique pet food premix.Although some moisture in pet food premix occurs naturally, especially with moisture in the air, too much moisture can diminish vitamin potency, cause caking of ingredients and lead to mold.

Vitamin Potency
Regardless of water’s form – liquid, vapor, or moisture in other ingredients – it can still negatively impact vitamins. Vitamins’ potency may decrease due to exposure to oxygen, minerals, pH effects, chemical activity and moisture level increases. Decreased potency could significantly impair pets’ ability to obtain their daily allowances of nutrients, thereby impacting their overall health.

Ingredient Caking
If a microingredient adsorbs a significant amount of moisture, caking, or clumping, of the ingredients can occur. Caking prevents the ingredients from being evenly distributed throughout the premix, which impairs the premix’s ability to be consistently spread throughout the final pet food.

An inadequately distributed premix could lead to a pet absorbing too much or too little of key vitamins and minerals. Either extreme can significantly impact the health of the pet. Ingredients particularly susceptible to adsorbing moisture can be treated with an anti-caking agent, or flow agent, to mitigate the issue.

Mold
Most premixes contain a carrier, an edible material to which ingredients are added to facilitate even distribution in the final pet food. Carriers should contain no more than 12% moisture. With high moisture, vitamin stability, clumping and mold all become concerns.

Moisture Testing
For all these reasons, it is important to know the moisture content of every ingredient to better predict the moisture level in the premix. Moisture testing can often be an overlooked quality control measure, but moisture can be the instigator of poor product performance.

Whereas third-party testing can take up to seven days for results, Trouw Nutrition’s Halogen Moisture Analyzer can provide results in just seven minutes. With this high-performance moisture analysis, we can provide a Certificate of Analysis of every product lot detailing what is an acceptable moisture level and the test results.
