The effect of the extraction procedure on the antioxidant capacity of extracts of pequi pulp: aqueous (AQ), alcoholic (ALC) and acetomethyl (AM), obtained respectively by the solvents water, ethanol and methanol followed by acetone, was investigated. Antioxidant action was expressed by the antioxidant capacity coefficient (K) obtained by the electrochemical test (DPV) at different pH values, and in trolox equiv...
Alho minimamente processado apresenta uma curta vida de prateleira devido, principalmente, a crescimento de fungos. A retirada da casca que protege o produto das influências externas é um dos fatores que contribui para a deterioração do produto. Neste estudo, foram avaliados os efeitos de revestimentos comestíveis antimicrobianos a base de amido de mandioca, quitosana e glicerol no recobrimento de alho minimame...
Este trabalho teve como objetivo a elaboração de uma bebida eletrolítica a base de permeado da ultrafiltração de leite e avaliação de suas características físicas, químicas e microbiológicas, durante o período de armazenamento por 30 dias, nas temperaturas de 7°C e 25°C. A bebida apresentou-se clara, com coloração amarelo-esverdeada, osmolalidade de 311,6mOsmol.L-1 e carboidratos totais de 6,48% m/v. Não foram ...
Avaliou-se o efeito da inclusão de 2,5; 5,0; 7,5 e 10,0% do farelo do resíduo de manga (FRM) variedade Ubá em dietas à base de milho e farelo de soja sobre o perfil lipídico sérico de frangos de corte. O delineamento foi inteiramente casualizado, sendo cinco tratamentos com seis repetições de 20 aves por unidade experimental. Avaliaram-se as concentrações de creatinina, albumina, proteínas totais, colesterol to...
O molho madeira se destaca pelo paladar e elegância na culinária. Como é bastante servido em eventos de grande porte como casamentos e aniversários, necessita ser preparado com certa antecedência e congelado. Porém, alguns possíveis problemas podem ser observados no descongelamento, como a segregação de fases e modificação dos aspectos originais, levando à perda das características sensoriais do produto. Assim,...
Blue polydiacetylene vesicles were studied with regard to their behaviour under variations in storage temperature, heating, potentiometric titration and in the presence of chemical components of milk, to evaluate their application as a sensor in the food industry. Vesicles were prepared using 10,12-pentacosadienoic acid (PCDA)/1,2-dimyristoyl-sn-glycero-3-phosphatidylcholine (DMPC). Their changes were monitored...
This study aimed to develop a value-added product concerning technological and sensory characteristics changes of the use of mechanically deboned poultry meat (MDPM) as meat replacer in lamb and mutton emulsion-type sausages (mortadella). Sausages were produced with lamb and mutton and with different contents of MDPM. Six treatments, using lamb or mutton and 0%, 30%, and 60% of MDPM in relation to the meat batt...
Present in most events, madeira sauce stands out for taste and elegance in cooking. Some companies, due to the large number of guests, need to prepare it with some advance. So that, the product can be prepared in this period, to improve the condition of the quality and organoleptic aspects, it is necessary its freezing after preparation. However, due to the freezing, potential problems can be observed, such as ...
The objective of this study was to evaluate the quality of water purification system and identify the bacteria this system, predict bacterial adherence according to the hydrophobicity of these microorganisms and of the polypropylene distribution loop for purified water. The assessment of drinking water that supplies the purification system allowed good-quality physical, chemical, and microbiological specificati...
Potatoes of the variety “Monalisa” were minimally processed like slices and submitted to different treatments, employed to decrease the enzymatic browning and growth of microorganisms. These treatments consisted on pure cellulose films (FP) or incorporated with active compounds (2% of citric acid (AC), 0,5% of L-cysteine Hydrochloride Monohydrate (CIS), 7% of sorbic acid (AS) and film incorporated with all of t...
