Psychrotrophic microorganisms in raw milk and the cheese quality

Molecular approaches to analysing the microbial composition of raw milk and raw milk cheese.

The availability and application of culture-independent tools that enable a detailed investigation of the microbiota and microbial biodiversity of food systems has had a major impact on food microbiology. This review focuses on the application of DNA-based technologies, such as denaturing gradient gel electrophoresis (DGGE), temporal temperature gradient gel electrophoresis (TTGE), single stran...

Incidence of psychrotrophic lipolytic bacteria in cow’s raw milk

The contamination of bulk samples of cow’s raw milk (n = 491) by psychrotrophic lipolytic bacteria (PLiBC), total count of psychrotrophic bacteria (PBC) and mesophilic bacteria (TBC) was monitored for two years on eight dairy farms and the correlations among these groups of bacteria were analysed. An increase in TBC, PBC and PLiBC and in the values of free fatty acids (FFA) was tested experimen...

Quality of raw milk in Kerman province

BACKGROUND: Microbiological and chemical qualities ofmilk are among the most important issues in public health.OBJECTIVES:Although there are a few published studies whichhave been conducted in south east of Iran this study wasperformed to investigate quality of raw milk delivered to a dairyindustry company Kerman Province. METHODS:Atotal of 109raw milk samples were collected at the time of deli...

Hygiene of Pasteurized Milk Depending on Psychrotrophic Microorganisms

Influence of storage temperature on the shelf life of the pasteurized milk and the enzymatic activity of psychrotrophic bacteria in whole and skimmed pasteurized milk were the main goals of the presented work. It was demonstrated that the storage temperature of 10C reduces the shelf life of pasteurized milk to one third in comparison with a storage at 4 C. The average shelf life of the full cre...
