Quantificação de contaminantes em aguardentes de cana/cachaças de alambique e de coluna

In the present study aimed to characterize and quantify four contaminants (ethyl carbamate, 2,3-butanedione, furfural and 5-hydroxymethylfurfural) present in alembic cachaça and industrial. Were collected forty-four samples of cachaça in the southern regions, the Midwest, southeast of Minas Gerais and São Paulo state, and subsequently subjected to physical, chemical and chromatographic analyzes. The physicochemical analyzes were performed according to the methodology described by the Ministry of Agriculture, Livestock and Supply (MAPA). The ethyl carbamate, 2,3-butanedione, furfuaral and 5 hydroxymethylfurfural were characterized and quantified by high-performance liquid chromatography (HPLC). The results of the ethyl carbamate analysis, it was found that both samples showed column cachaças outside the standards required by law, with the values 245.31 235.53 L-1 ug and none of the liquor samples alembic showed concentration greater than 210.0 ug L-1 , and the method is very sensitive to low limits of detection and quantification. In determining 2,3-butanedione, it was revealed that the column cachaças showed higher levels of contaminants when compared to cachaça alembic. In the quantification of furfural and 5-hydroxymethylfurfural was developed and validated analytical methods employed to high-performance liquid chromatography (HPLC) with DAD detector. Samples column cachaças showed higher values than the limit established by Brazilian legislation and ranged from 7.00 to 5.63 mg / 100 ml of anhydrous alcohol over the alembic cachaça.

Análise microbiológica e físico-química de material proteico comestível derivado do processamento da gordura oriunda do abate de bovinos

Background: The use of all by-products of bovine slaughter is of high economic importance for the industries of products of animal origin. Among these products, fat has an important role, once fat rendering may generate several different products, such as protein material that may be used in the manufacture of meat products. However, in spite of the importance that the use of all by-products has for the economic balance of the industry, there are no reports on their use in Brazil, or studies that supply data on microbiological and physical-chemical local standards for this protein. Thus, the objective of this study was to evaluate microbiological and physical-chemical characteristics of protein material obtained from fat rendering, as well as to provide support for companies to use fat rendering to generate protein material, adding value to industrialized meat products.Materials, Methods & Results: The experimental production of edible protein obtained of fat rendering was conducted in slaughterhouse with supervision of the Brazilian Ministry of Agriculture, Livestock and Food Supply. Protein material was obtained in a continuous, humid heat system at high temperatures. Fat scraps containing protein were ground and cooked at high temperature (85 degrees C), and placed in a three phase decanter centrifuge. After centrifugation, protein material was ground again and packed. Samples were collected from 15 batches of protein material, and the following microbiological analyses were carried out: counts of aerobic mesophilic and psychrotrophic microorganisms, coliforms at 35 degrees C, Escherichia coli, sulfite-reducing Clostridium, and Staphylococcus aureus, besides presence or absence of Salmonella and Listeria monocytogens. The following physical-chemical analyses were also carried out: protein, total lipid, moisture, ash, carbohydrate, and energy content. Mean counts of mesophiles, psychrotrophs, and coliforms at 35 degrees C were 4.17; 3.69 and 1.87 (log CFU/g), respectively. Levels of protein, total lipids, moisture, ashes and carbohydrates were 27.50; 7.83; 63.88%; 0.24%; and 0.55%, respectively, and energy content was 182.63 kcal/100g.Discussion: Results of microbiological analyses demonstrated that, although low, the final product showed to be contaminated. Contamination that occurred during the second grinding procedure may be an explanation for these bacterial counts. Also, the temperature used for fat fusion was not enough to eliminate thermoduric microorganisms. However, even with the presence of indicator microorganisms in the samples, none was contaminated by E. coli, sulfite-reducing Clostridium, S. aureus, Salmonella or L. monocytogenes. Physical-chemical analyses showed that the product had adequate nutritional quality. Based on these results, it was possible to conclude that protein material obtained in fat rendering showed characteristics that enable the use of this product as raw material for processed meat products. Besides, the present study was the first one to present scientific results in relation to edible by-products obtained in fat rendering, supplying important information for slaughterhouses and meat-processing plants. The study also produced relevant data on the innocuousness of the product, which may be used to guide decision-making of health inspectors.

Tuberculose e sua importância para a pecuária brasileira

Tuberculosis due the large number of victims that come attacking in recent years has become a major concern in the World Health Organization. It is caused by a bacterium that is becoming increasingly resistant to drugs, because it requires long periods in treatment that are not always followed correctly. AIDS has contributed much in recent years with increased morbidity and mortality of Mycobacterium. The Ministry of Agriculture, Livestock and Supply (MAPA) of Brazil in 2001 created the National Program of Control and Eradication of Animal Brucellosis and Tuberculosis (PNCEBT) establishing guidelines such as: sets the method to diagnose, control and certify herds free of disease.
