Milk from different animal species has variable levels of antimicrobial factors against some of spoilage bacteria. For example, they are significantly present in higher concentration in she-camel's milk than in cattle or buffalo and they are more heat-resistant than their counterparts in cattle and buffalo. Spoilage bacteria are known to communicate with each other by release of signaling molec...

Fermentation of milk yields many other products apart from lactic acid. This study was carried out to monitor the progress of fermentation by measuring the total solute concentration i.e. osmolality in fermenting milk. Five samples each of raw milk, pasteurised milk and UHT (ultra-high temperature treated) milk were incubated aerobically without starter culture at 37°C for 3 days. Osmolality wa...

The present study was undertaken with the aim of investigating the physical parameters (e.g. organoleptic and specific gravity of raw milk) and also to study the microbiological quality of raw milk (total viable count, Coliform count and Staphylococcal count) from different villages and Bangladesh Agricultural University (BAU) Dairy Farm of Mymensingh District of Bangladesh, during the period f...

During the last decades, the world has witnessed a dramatic increase in allergy prevalence. Epidemiological evidence shows that growing up on a farm is a protective factor, which is partly explained by the consumption of raw cow's milk. Indeed, recent studies show inverse associations between raw cow's milk consumption in early life and asthma, hay fever, and rhinitis. A similar association of ...

Milk consumption in the semi-arid regions of Kenya is not well understood. A study was carried out on consumption of milk and milk products in the semi-arid region of eastern Kenya. A total of 135 rural and 126 urban households were interviewed. Raw milk was the most popular and was consumed by 99% and 84% of rural and urban households, respectively. Generally as degree of processing increased,...

The raw milk quality has increasing importance for producer and consumer as it is directly related to processing, production and price. The aim of present study was to determine the relationship among intramammary infection (IMI) and raw milk parameters in Jersey crossbred cows. Total 24 lactating Jersey crossbred cows were randomly selected and representative animal wise morning milk samples w...

Background and Aims: Staphylococcus aureus (S. aureus) is considered as one of the most dangerous pathogenic bacteria due to the production of extracellular toxins. The objective of this study was to determine the prevalence of S. aureus and to characterize the recovered strains for their enterotoxin-producing genes in raw cow milk. Materials and Methods: During 9 months duration of the s...

Aflatoxins are natural toxic compounds produced by fungi such as Aspergillus flavus and Aspergillus parasiticus. Due to higher temperature and humidity, fungi are continuously grown and contaminated the cereals and cereal by-products with aflatoxin B1 (AFB1). Dairy cows fed AFB1 contaminated feeds can produce milk contaminated with aflatoxin M1 (AFM1). Therefore, the aim of this study was to in...

Many volatile compounds generated during the thermal processing of milk have been associated with cooked, stale, and sulfurous notes in milk and are considered as off-flavor by most consumers. A headspace solid-phase microextraction (HS-SPME)/gas chromatographic technique for the quantitative analysis of thermally derived off-flavor compounds was developed in this study. The extraction temperat...

OBJECTIVE To evaluate microbial quality and associated health risks of raw milk marketed in the Tanga region of Tanzania. METHODS A microbial quality assessment of marketed raw milk was undertaken by evaluating 59 samples of milk from selling points (collecting centres =15), bicycle boys (12) and kiosks/restaurants (32) in Tanga city during April-May 2005. Quality and milk-borne hazards were ...
