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.
Water activity meter for food.
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.
To make a measurement flip back the sensor cover and fit the pawkit over a standard aqualab sample cup.
Water activity can have an influence on a products shelf life odour colour flavour or texture.
This results in a longer shelf life.
Low acid canned foods can be.
If a product is kept below a certain water activity then mold growth is inhibited.
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.
These water activity meters are used around the world in many industries from food and pharmaceuticals to oil and chemicals.
Food designers use water activity to formulate shelf stable food.
It is the most commonly used criterion for safety and quality.
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.
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.
The water activity a w concept has served the microbiologist and food technologist for decades.
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.
Meter food is the leading food safety device manufacturer.
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.
Visit the cgoldenwall store water activity or aw indicates the free water content when food is stable measures the possibility of microbial proliferation.
Aqualab water activity meters are fast and reliable in every single aspect.
