background and objectives: pre-requisite programs (prps) are “primary conditions and requirements essential for haccp operations, which are crucial in food safety programs”. the present study was conducted to evaluate the impact of implementation of prps on the microbial parameters of pasteurized milk (according to the national standard of iran). effectiveness of haccp operation requirements an...

introduction: there are a lot of fungi in the air and our environment that grow and reproduce if the temperature and humidity are suitable. aspergillus flavus and parasilicus are among the most important food contaminants which have a role in food poisoning. these fungi secrete poisons which contaminate animal feed as well as the milk we get from the animals fed with these foods. methods: in th...

this research with the aims of microbial flora determination in pasteurized milk and it’s shelf life study based on microbial and physicochemical parameters were performed within 10 days. in this study, 60 pasteurized milk samples randomly were selected and then total count of bacteria and total psychrophilic bacteria count were performed. to investigate microbial flora of pasteurized milk, col...

Background: Milk is considered as one of the highly nutritious food for human. This study was undertaken to evaluate the physicochemical as well as the microbial quality of pasteurized milk of different brands available in Chittagong, Bangladesh. Methods: Five types of branded pasteurized liquid milk were collected from retail markets of Chittagong, Bangladesh. Physicochemical analyses were ca...

AIMS The aim of this study was to identify the causative agent of a smoky/phenolic taint in refrigerated full cream chocolate milk. METHODS AND RESULTS Microbiological examination of spoiled and unspoiled milk samples from the same processor showed high numbers of the psychrotrophic coliform Rahnella aquatilis in the spoiled samples only. Gas chromatography/mass spectrometry (GC/MS) was used ...

BACKGROUND Fragility fractures associated with osteoporosis extract a large financial and personal toll on society. Pharmaceutical or dietary calcium intake is needed to increase bone mineral density to prevent fragility fractures. Although dairy products are a good source of calcium, patients who are unable to digest lactose tend to avoid them and are put at a greater risk for fracture than th...

s: In the present study, 20 samples of milk of cow, pasteurized milk were collected from the local market and were analyzed for microbial count and IMViC tests to determine the coliform load in the sample. Further, the presence of E. coli (KC795687) was confirmed by using PCR and 16srna sequencing. Majority of the milk samples of different origin were found to be contaminated by the coliform gr...

Sixty pasteurized milk samples were collected aseptically from different processing dairies and analyzed for total viable count and aerobic spore count. Bacillus subtilis was found to be the predominant aerobic spore former (33.33%) followed by B.megaterium (24.44%), B.licheniformis (17.77%), B.cereus (8.88%), B.coagulans (6.66%), B.pumilus (4.44%), B.sphaericus (2.22%), and B.circulans (2.22%)...

Six nursing mothers ingested 113 gm of Hershey's milk chocolate containing 240 mg of theobromine. Samples of plasma, saliva, and breast milk were assayed for theobromine by high pressure liquid chromatography. Peak theobromine concentrations of 3.7 to 8.2 mg/l were found in all fluids at 2 to 3 hour after ingestion of chocolate. The disposition half-life of theobromine averaged 7.1 +/- 2.1 hour...
