MEDIA RELEASE - GRAINTEC PTY LTD

DEC 2007

IFT AWARD WINNER NOW IN AUSTRALIA

Graintec would like to announce the release of an award winning product – the Aquasorp isotherm Generator.  The AquaSorp Isotherm Generator effectively control product formulation and stability, moisture sensitivity, temperature effects and drying characteristics and provides answers in less than 24 hours as opposed to the 2-5 weeks offered by previous instruments.
“The isotherm predicts how an ingredient on a recipe will respond to moisture” says Ron Leaman of Graintec Pty Ltd.  “You can therefore tinker with a recipe and predict how water activity will change as you change the formulation.” 
The technology is fast and at a cost that researchers and technologists can now afford.
An increase in water activity is almost always accompanied by an increase in water content, but in a nonlinear fashion.  Moisture sorption isotherms are sigmoidal in shape for most foods.  A few uses for isotherms include:
• Monolayer moisture content determination
• Determine critical water activity or moisture content limits for crispness, hardness, and flow properties
• Maximize moisture contents at safe water activities through formulation adjustment
• Adjust drying process controls to achieve a safe water activity that maximizes moisture content and avoids over drying.
• Determine shelf life and storage stability of a product

Graintec have been supplying water activity instruments to food manufacturers for years and the new Isotherm Generator uses the same chilled mirror technology.  “We are delighted to introduce the new technology as it will compliment our range of water activity instruments.  We can now assist manufacturers with intense product formulation testing in the lab through to “on the spot” water activity checks on the production floor.”
In 2008, Graintec will be conducting “Water Activity” seminars across major capital cities. Further information can be obtained by contacting Graintec on 07 4638 7677.
(Graintec Pty Ltd is the sole authorised distributor for Decagon devices in Australia.  Decagon is the world leader in the measurement of water activity and manufacturer of the Isotherm Generator.)
