Clostridium sporogenes is a food contaminating anaerobic bacteria causes late bowing effect in cheeses and spoilages in other dairy products. A total of 150 samples were studied for the presence of Clostridium sporogenes in raw milk, curd and cheese samples. Out of 150 sample 11(22%) Clostridium sporogenes was found in raw milk, 7(14%) in curd and 2(4%) in cheese samples. The study shows the ex...

This manuscript offers a comprehensive review about the bacterial amino acid decarboxylase activity and biogenic amines content of an artisanal cheese produced in Italy, named as Pecorino cheese. It is highlighted the importance of controlling primary production of raw milk, as well as cheese-making process to avoid the release of free amino-acids and viability of microorganisms possessing amin...

The aim of this study was to determine the chemical and microbiological analysis of soya cheese and compare with cow milk cheese and raw soya. Fat content is lower and protein content is higher in soya cheese than cow milk cheese. Moisture, ash, fat, total carbohydrate, total energy, pH, total chlorides and Total solids are significantly higher in cow milk cheese than soya cheese. Cheese yield,...

Pecorino Siciliano (PS) "primosale" is a traditional Sicilian fresh soft cheese made from sheep's milk. Short-ripening time and production from unpasteurized or raw milk can facilitate bacterial contamination of PS "primosale". The microbiological quality of "primosale" on retail sale in the street markets of Palermo, Italy was studied by detecting the common food pathogens Listeria monocytogen...

Comparat i ve stud i es were made on the composition, microstructure and organolepti c quali t y of soft brine cheese made f rom instant whole mi I k powder and from raw mi I k. The chemi ca I analysis of young and ripened (one and two month) cheese re vealed similarity except fo r a higher salt content in the cheese made from reconstituted milk at the end of ripening . Electron microscopic stu...

Objective of this study was to investigate the effect of short term frozen storage of milk and curd on textural properties and physico-chemical composition of white brined goat cheese. Raw milk and curds (at various stages of pressing) were frozen and kept for seven days at -27 °C. Following the freezing, all the experimental cheeses were manufactured by the standard procedure, the same that wa...

Artisanal cheese and other dairy products are traditionally produced from raw milk. The chemical and microbiological properties of milk are besides technological procedure among the most important parameters that determine the final characteristics of a product. Majority of microbes present in the rich microbiota of raw milk are considered beneficial but we should also be aware of a possibility...

24 In 2005, the Belgian authorities reported a Listeria monocytogenes contamination episode in 25 cheese made from raw goat’s milk. The presence of an asymptomatic shedder goat in the herd 26 caused this contamination. On the basis of data collected at the time of the episode, a 27 retrospective study was performed using an exposure assessment model covering the 28 production chain from the mil...

Traditional products and related processes must be safe to protect consumers' health. The aim of this study was to evaluate microbiological criteria of a traditional Piedmont cheese, made by two different cheese producers (A and B). Three batches of each cheese were considered. The following seven samples of each batch were collected: raw milk, milk at 38°C, curd, cheese at 7, 30, 60, 90 days o...

The production of extracellular hydrolases by a psychrotrophic bacterium isolated from refrigerated raw milk, and identified as a Pseudomonas sp. belonging to the Pseudomonas jenssenii group, was studied. This bacterium produced proteolytic and lipolytic enzymes in all media investigated (skim milk, cheese whey, casein broth, and tryptone soy broth). High levels of α-glucosidase were produced i...
