Epidemiologia molecular aplicada ao monitoramento de estirpes de Staphylococcus aureus na produção de queijo Minas frescal

We studied the molecular epidemiology of Staphylococcus aureus strains potentially toxigenic, isolated from the production process of Minas frescal cheese in a small dairy plant in the state of São Paulo. For this, samples were taken during the period from June 2008 to July 2009. Samples were collected from the surface of the receiving and storage tanks of raw milk, the surface of the balance tank of pasteurized milk, the water supply system, the pipes and equipments, the hands of the handler and from the packaged cheese, totaling 140 samples. The colonies isolated on Baird-Parker Agar confirmed as Gram positive and positive for catalase, coagulase and acetoin production, were submitted to extraction of bacterial DNA using the Invitek - Uniscience® kit. Confirmation of the isolated species and enterotoxins SEA, SEB, SEC, SED and TSST-1 toxin was carried out through the amplification of specific fragments of chromosomal DNA. Among the 74 strains of isolated coagulase-positive staphylococci, only 41 (55.4%) strains were confirmed as Staphylococcus aureus, of which 25 (61.0%) were positive to the presence of staphylococcal toxins. The most frequently identified enterotoxin was SEA. The toxigenic strains of Staphylococcus aureus were more frequently isolated from hands of the handler (16.0%), raw milk receiving tank (12.0%), pasteurized milk for cheese making (12.0%) and fresh white cheese ready for consumption (12.0%).

Avaliação de qualidade de amidos de mandioca modificados utilizados na fabricação de pão de queijo

The food industry looks for new ways and strategies to standardize the marketing products in the customer market. The modification of the cornflour that are produced in the manufacturing of the cheese bread has been one of the these ways, since some raw materials that are used to make the cornflour present different features in each supplyed allotment. The present research had as a main purpose to analyse such features looking forward to improving the quality of the final product. Thus, some tests were done to verify the pH, humidity and acidity; it was checked the percentage of carbonyl and carboxylic groups and the power of expansion to five different allotments and to farina, for example: pre-gel, natural, expandex farina as the combination of the three cited kinds. After diversifying the allotments, different results were acquired, even to an unique kind of farina and it was not possible to correlate the results of acidity, the percentage of carbonyl and carboxylic groups and the power of expansion. The pH and humidity are proper for each kind of farina. This way, the raw materials that are used for each cheese bread manufacturing must be analysed in each allotment

Avaliação da composição química, proteólise e propriedades funcionais do queijo mussarela comercial com teor reduzido de gordura

Chemical composition, proteolysis and functional properties of commercial Mozzarella cheese with reduced fat content found in the market of Londrina – PR were evaluated. The cheeses were analyzed for chemical composition, meltability, free oil formation, and the indexes of extension and depth of proteolysis during 30, 45 and 60 days of storage at 5°C. The samples showed no significant difference in chemical composition. The fat content of all samples complied with current legislation regarding the minimum percentage (25%) of fat reduction. Among the three brands tested, the cheeses of brand C showed the highest depth index of proteolysis. In all chesses, the meltability has increased during storage period. The, the brand C had significantly higher (p <0.05) free oil content when compared to other brands tested.

Percepção de desconforto na utilização de um produto: ralador de queijo

This study presents an analysis of the discomfort in the use of a cheese grater. Data was collected using a protocol of perceived discomfort and the results show that the subjects with no experience in cooking reported more experiences of discomfort and higher intensity than the subjects with experience in cooking.
