Volatile sulfur compounds have been reported to be responsible for the sulfurous off-flavors generated during the thermal processing of milk; however, their analysis has been a challenge due to their high reactivity, high volatility, and low sensory threshold. In this study, reactive thiols were stabilized and the volatile sulfur compounds in milk were extracted by headspace solid-phase microex...

Commercial infrared (IR) milk analyzers are being increasingly used in research settings for the macronutrient measurement of breast milk (BM) prior to its target fortification. These devices, however, may not provide reliable measurement if not properly calibrated. In the current study, we tested a correction algorithm for a Near-IR milk analyzer (Unity SpectraStar, Brookfield, CT, USA) for fa...

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...

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...
