Food microbiologytechniquesAn improved gravimetric method was used to simultaneously determine (in a single assay) the water activity ( a w ) of 30 solid and liquid culture media covering the entire useful range of a w in food microbiology, including media recommended for osmophilic, halophilic ...
Furthermore, the book discusses water activity and the growth of food spoilage and pathogenic organism; water relations of enzymic and non-enzymic deteriorative reactions in food; effects of freezing and thawing of water in food systems; and the significant aspects of food quality as affected by...

Water activity and its estimation in food systems Berg, E. Van-Den; Bruin, S., 1981: Water activity and its estimation in food systems: theoretical aspects. Water activity: influences on food quality: a treatise on the influence of bound and free water on the quality and stability of fo....
Physiological Response of Escherichia coli O157:H7 Sakai to Dynamic Changes in Temperature and Water Activity as Experienced during Carcass Chilling. Enterohemeorrhagic Escherichia coli is a leading cause of foodborne illness, with the majority of cases linked to foods of bovine origin. Currently, no...
Controlling water activity ( a w ) can significantly impact the growth of Salmonella in poultry litter and manure — a phenomenon that was studied quantitatively using two common serotypes of Salmonella . The quantitative effect of changes in levels of a w on Salmonella populations was determined ...
polyols (glycerol, propylene glycol, sorbitol, 1,3-butylene glycol, polyethylene glycol200, and polyethylene glycol 400) and various alkali metal chlorides (KCl, NaCl, LiCl, and CsCl) on the kinetics of nonenzymatic browning in glucose-lysine solutions, of high water activity (aw) was studied....
KR Davey - 《Journal of Applied Microbiology》 被引量: 306发表: 1989年 Fermentation and epiphytic microflora dynamics in sugar cane silage Sugar cane silages are characterized by extensive yeast activity, alcohol production and great dry matter - DM - losses. Better knowledge of the fermentati.....
Autoradiographic methods have been developed to detect metabolic activity of viable but nonculturable cells of Helicobacter pylori in water. Four strains of H. pylori were studied by using microcosms containing suspensions of 72-h cultures in water. The suspensions of aged, nonculturable cells of H...
This book contains the outcome of their work. It has been written with the express objective of using simple but accurate wording so as to be accessible to all microbiology laboratory staff. To facilitate reading, the more specialized items, in particular some statistical treatments, have been add...
