The sun meat is a half-dehydrated product obtained by light salty and discrete drying of meaty cuts of bovines, that although appreciated in northeastern Brazilian it is a product without techniques standard for production and standard of identity and official quality. It was objectified to evaluate the quality of the sun meat commercialized in the city of João Pessoa, focusing four axles, being the first one to evaluate the hygienical-sanitary aspects of the establishments that commercialize sun meat; as the axle to determine the parameters physical and chemical; third to trace the profile of the consumer of sun meat and the room axle it aimed at to establish quality attributes. The studies on the hygienical-sanitary aspects of the establishments had been lead in two phases, collect and quantification of the data. The characterization physical and chemical was carried through in 51 samples, gotten randomly in retail establishments; becoming fullfilled the determination of moisture, pH, activity of water, proteins, fats, chlorides, ashes; water holding capacity and determination of color. To trace the profile of the consumer of sun meat, they had been considered: the characterization of the sample; consumption habits; elements used for purchase decision; degree of satisfaction of the consumers and crossing of data, by means of not probabilist sampling gotten next to 326 consuming potentials of sun meat, using itself a structuralized questionnaire contend 16 questions. To establish sensorial attributes three sessions of Focus Groups had been carried through. In the hygienical-sanitary evaluation it was verified that the supermarkets are the establishments with optimum profile and the free fairs and public markets are the establishments with the worse hygienical-sanitary pointers. Microbiologically the estafilococos coagulase positive had not been detected in the evaluated samples, however the countings of Staphylococcus spp had varied of 6,4 x 102 the 2,0 x 106 UFC.g-1, the countings of aerobic bacteria mesophilic ranged had varied of 1,8 7,5 x 105 and x 107 UFC.g-1, the total coliformes had been between 4,6 x102 and 1.1 x 109 NMP. g-1 of sample and molds and yeasts ranged from, had varied of 2,5 x 102 and 1,0 106 x UFC.g-1. The contamination for total and termotolerantes coliformes reflected the standard hygienical-bathroom of the small markets, supermarkets, butchery and supermarkets ; not being observed for the free fairs and public markets, where the microbiological evaluation did not reflect the classification. The correlation between the standard was observed hygienical-bathroom and the counting of mesófilos for butchery, supermarkets, free fairs and hipermercados, however, as many as the small markets, as the public markets had not followed this relation. The quality parameters physical and chemical had ample variation, being observed the following averages: moisture (71,17±2,96g/100g); pH (5,93±0,26); activity and water (0,95±0,03); protein (22,86±1,50 g /100g); fat content (0,67±0,41 g /100g); water holding capacity (77,59± 5.59%), chloride (2,03±0,98 g/ 100g); ashes (4,83±2,07 g/ 100g); internal and external average values of luminosity (19,79±2,01 and 18,85±2,10); values of intensity of the red color, internal and external (4,47±2,13 and 10,38±2,61) and external values of yellow intensity, interns and (21,57±0,93 and 21,91±1,08). In the analysis for grouping it was observed existence of four classrooms of establishments determined for the origin of the sun meat. It was demonstrated the satisfaction of the consumer with regard to the acquired sun meat. The place of the purchase of the sun meat is chosen by the hygiene of place (42%) and the preferred form of consumption is the frying (80.7% of the interviewed ones); 87.5% had declared to consume sun meat one or more time per week and the lunch is the consumption occasion more frequently; the supermarket is the preferred local to purchase the sun meat for 51,5% of theinterviewed ones. The sun meat is element of the diet for cultural habits, the easiness of reparation and also for the characteristic flavor.
