Microbial Safety of Low Water Activity Foods:

Abstract. Sixty household low water activity foods were examined and a simulative study was conducted in a high sugar, low almond and macadamia butter to determine the survival of Bacillus cereus and Staphylococcus aureus ATCC 25923. Results obtained from 60 low samples collected at household level had some significant differences within food categories amongst

WATER ACTIVITY PROFILE AND MICROBIAL SAFETY OF HOT

For microorganisms to thrive in food products, it needs some appreciable water before the microorganisms can grow in food products. There is a required amount of water that promotes the growth of microorganisms; microbiologists have certain determinants or requirements that facilitate the growth of microorganisms in the shape of water activity (Rahman 2010).

Food Safety Information Papers

Water activity (aw) is a measure of the state or condition of water in foods (e.g., availability for microbial growth). Water activity values theoretically range from 1.0 (pure water) to 0 (absolutely no water available). The water activity of a food product depends upon the amount and nature of solutes present. Controlling water activity is ...

Water Activity (A w) Every microorganism has a minimum, optimum, and maximum water activity for growth. Water activity is a mea-sure of the water available for microbial growth. The water activity is measured instrumentally using either an electric hygrometer or a dew point instrument. Yeasts and molds can grow at low water activity.
