13. Utilização do amido da casca de mandioca na produção de vinagre: características físico-químicas e funcionais / Use of starch from cassava peel in the production of vinegar: physicochemical and functional characteristics
O presente trabalho objetivou produzir vinagre a partir da casca de mandioca, assim como avaliar as suas características físico-químicas e funcionais. Para tal, a casca de mandioca foi sanitizada, seca em estufa a 55C, por 24 horas e triturada. A casca de mandioca apresentou pH de 4,85 0,05; 72,53 0,09 g (100g)- de umidade; umidade da farinha de 11,75 0,1

14. Bebidas de Kefir com e sem inulina em versões integral e desnatada : elaboração e caracterização química, física, microbiológica e sensorial
The beverage Kefir is a result of fermentation of milk by lactic acid bacteria, aceticacid bacteria and yeasts contained in Kefir grains or in lyophilized starter culture. Besides bacteria and yeasts, the beverage contains minerals, vitamins B and essential amino acids, important for the maintenance of the vital functions of the organism. The beverage consum

16. Evaluation in vitro and vivo of the cheese whey fermented by the consortium of bacteria Enterococcus faecium and Veilonella parvula in the feeding of ruminants / Avaliação in vitro e in vivo do soro de leite fermentado pelo consórcio de bactérias Enterococcus faecium e Veilonella parvula na alimentação de ruminantes
The industry of dairy products is gradually growing along the last years, standing out the cheese production. One of the by-products obtained of the production of the cheese is the cheese whey. This one presents high demand biochemistry of oxygen (DBO), that when being discarded in rivers or public sewers, it represents important environmental problem. Like

17. Volatile composition and flavour of Italian types dry fermented sausage produced in Brazil / Composição de volateis e earoma de salames nacionais tipos Italiano e Milano
Dry-fermented sausages are meaty products resulting from fermentation and dehydration/ripening processes. They are produced and consumed worldwide because of their typical sensory characteristics mainly in relation to the aroma and flavor. In Brazil this product has reached successive record sales in the internal market, with a total sale of R$ 265 million d

19. "Application of voltametric and HPLC techniques on the monitorins of organic acids production in fermented milk samples by Kefir and Tibet grains" / "Monitoramento da produção de ácidos orgânicos em amostras de leite fermentado pelos grãos de Kefir e do Tibet utilizando técnicas voltamétricas e HPLC"
The products formed during the milk fermentation using the kefir and tibet grains (popularly known species) were studied in this work. The kefir grain is a symbiotic association of microorganisms that includes several species of lactic acid bacteria (Lactobacillus, Lactococcus, Leuconostoc), yeasts (Saccharomyces cereviseae) and acetic acid bacteria (Acetoba

20. Important volateis composites for the aroma of jenipapo (American Genipa L.) e murici (crassifolia Byrsonima L. RICH). / Compostos volateis importantes para o aroma de jenipapo (Genipa americana L.) e murici (Byrsonima crassifolia L. RICH).
The volatile compounds are responsible for the characteristic flavor of food. They are present in a wide interval of concentration, possessing varied chemical structure, beyond of being, generally heating labil. Usually the flavour of a product is constituted by hundreds of volatile compounds. However, only some compounds efftectivelly contribute to the over

21. Produção e caracterização de aromas de frutas por microrganismos pectinoliticos utilizando-se residuos agroindustriais. / Production and characterization of fruits flavor for pectinolytic microorganisms using agro-industrial residues.
Pectinases were some of the first enzymes used in commercial applications of wines and fruit juices since 1930 and their use has increased considerably, specially in food, brewery and wine, textile, pulp and paper industries. Today, these enzymes account for approximately 20% of the world enzyme market. Plants, fungi, yeasts, and bacteria naturally produce t

22. Isolamento, seleção, identificação e parametros cineticos de bacterias aceticas provenientes de industrias de vinagre
The industrial production of vinegar has so far only insufficiently benefited from research on acetic bacteria. Hence, in spite of being highly qualified in terms of equipment, it is microbiologically deficient. The aims of the present work are (1) to study and standardize the isolation of strains used in the production of highly acid fermented vinegar, (2)

23. Estudo do melhoramento do sabor de cacau (Theobroma cacao L.) atraves de ação enzimatica durante a fermentação
The fermentation of cocoa beans is an indispensable activity for the development of the precursors of chocolate flavor. During this stage the pulp that surrounds the beans is metabolized by microrganisms, producing, mainly, ethanol and acetic acid which are absorbed by the cotyledons resulting in the death of the seed, with several physical-chemical changes

24. Estudo do melhoramento do sabor de cacau (Theobroma cacao L.) utilizando polifenoloxidase extraida da pinha (Annona squamosa L.) e tratamento termico não convencional
Considerable variations in the taste of cocoa occur according to the region of production, some regions producing excessively acid, bitter and astringent cocoa beans. In general, cocoa beans produced in Brazil and Malaysia are characterized by excessive acidity as compared with those from East Africa, limiting the amounts of these beans that can be used in f
