1. Psychrotrophic bacteria in Brazilian organic dairy products: identification, production of deteriorating enzymes and biofilm formation
Abstract The psychrotrophic bacteria count and the profile of Gram-negative bacteria present in commercial Brazilian organic dairy products (27 samples, pasteurized whole milk, Minas Frescal cheese, and yoghurt, equally distributed) as well as the biofilm-producing capacity and the production of deteriorating enzymes were investigated. Most of the samples (5

2. Evaluation of a rapid detection method of Salmonella in comparison with the culture method and microbiological quality in fish from the Brazilian Amazon
Abstract Microbiological safety of fish is a concern of consumers, industries and regulatory agencies worldwide. Among the pathogenic microorganisms, Salmonella spp. is one of the main agents of foodborne diseases and should be absent in animal products. Rapid and accurate identification of pathogens in the supply chain is important for both quality assuranc

3. Pseudomonas SP. in uninspected raw goat’s milk in Rio de Janeiro, Brazil
Abstract Although quite controversial from the point of view of food safety, a considerable number of people across different age and socioeconomic groups consume raw goat’s milk. Even if refrigerated after milking, raw goat's milk may still be susceptible to the lipolytic and proteolytic actions of psychrotrophic microorganisms, such as Pseudomonas. In th

4. The effect of the commercial fish gelatin protein hydrolysate on rainbow trout (Oncorhynchus mykiss) fillet quality
Abstract Willing to increase the shelf life of the food matrix, studies regarding new preservations methods are developed to preserve fish deterioration. The application of natural additives as preservatives is increasingly common, with a current emphasis on the growing use of protein hydrolysates, in substitution to artificial ones. These compounds have bee

5. Physical-chemical characterization, microbiological and biocompounds of cashew pulp in industrial and freezing processing
Abstract This study aimed to evaluate the nutritional characteristics, bioactive compounds and microbiological quality during the processing and frozen storage of cashew pulps. Cashew pulps from 4 batches and 3 different sequential stages of industrial processing and storage (after pulping, after pulp thawing that was stored for 3 months in a drum, and 90 da

6. The shelf life of standardized sugarcane juice stored under refrigeration
Abstract The shelf life (SL) of freshly extracted sugarcane juice is limited to a few hours, and the use of hurdle technology is a strategy to ensure its safety and stability. The SL of standardized cane juice (19.4 °Brix, 0.085% acidity and pH 4.35), pasteurized at 95 °C/30 s and stored under refrigeration, was estimated. Ideal (4 °C), commercial (8 °C)

8. Pseudomonas spp. and other psychrotrophic microorganisms in inspected and non-inspected Brazilian Minas Frescal cheese: proteolytic, lipolytic and AprX production potential
RESUMO: O mais consumido no Brasil, o queijo Minas Frescal (QMF) é altamente suscetível à contaminação microbiana e a produção e comercialização clandestina podem representar um risco para a saúde do consumidor. O armazenamento deste produto fresco sob refrigeração, embora mais apropriado, pode favorecer a multiplicação de bactérias psicrotró

11. Microbiological quality of minimally processed vegetables commercialized in Brasilia, DF, Brazil
Abstract This study evaluated the microbiological quality of minimally processed vegetables commercialized in the city of Brasilia, DF, Brazil. A total of 32 samples of different vegetables were purchased from 10 supermarkets. In most samples (78.1%) the populations of psychrotrophic bacteria had a high count ranging from 106 to 108 CFU/g.

12. Quality indicators and shelf life of red octopus (Octopus maya) in chilling storage
Abstract There are no precedents concerning the quality of Octopus maya during chilled storage. This study evaluated the shelf life of the red octopus in chilling storage (4oC) and the correlation of the sensory quality index with microbiological counting and the biochemical indicators (hypoxanthine, histamine and volatile amines). A total of 112 whole raw o
