These water activity meters are used around the world in many industries from food and pharmaceuticals to oil and chemicals.
Water activity meter for food.
As a potential energy measurement it is a driving force for water movement from regions of high water activity to regions of low water activity.
Low acid canned foods can be.
The water activity a w concept has served the microbiologist and food technologist for decades.
Aqualab water activity meters are fast and reliable in every single aspect.
With a limited 0 02 a w accuracy the pawkit should only be used to verify readings or where a higher accuracy reading is not critical.
To make a measurement flip back the sensor cover and fit the pawkit over a standard aqualab sample cup.
It is the most commonly used criterion for safety and quality.
This results in a longer shelf life.
Visit the cgoldenwall store water activity or aw indicates the free water content when food is stable measures the possibility of microbial proliferation.
Food designers use water activity to formulate shelf stable food.
If a product is kept below a certain water activity then mold growth is inhibited.
Water activity s usefulness as a quality and safety measurement was suggested when it became evident moisture content could not adequately account for microbial growth fluctuations.
One can therefore not predict even the direction of the change of water activity with temperature since it depends on how temperature affects the factors that control water activity in the food.
Push the button for a water activity reading in 5 minutes.
Water activity aw or erh equilibrated relative humidity is a measure of the free water in a product water which is not bound into the product in any way and which is available for the growth of moulds and the proliferation of bacteria.
Meter food is the leading food safety device manufacturer.
Food formulators use water activity to predict how much moisture migration will affect their product so that to choose suitable package and storage method to reduce the usage of antiseptics.
The water activity instruments can be used in water activity measurement for process and quality control on the production line or for laboratory analysis and product development.
Water activity values can also help limit moisture migration within a food product made with different ingredients.
