Desenvolvimento de bebida láctea potencialmente probiótica carbonatada: características físico-químicas, microbiológicas e sensoriais

The goal of this work was to develop a strawberry fl avored dairy beverages carbonated and fermented with potential probiotic bacteria. Four formulations of dairy beverages were elaborated: Control (BL); Fermented (BLF); Carbonated (BLC) and Carbonated Fermented (BLFC). In samples submitted for carbonation, a carbonator was used for the carbon dioxide (CO2 ) gas injection dissolved in drinking water and the cultivation consisting of lactic bacteria Lactobacillus acidophilusLA-5®, Bifi dobacterium BB-12® and Streptococcus thermophilus (Biorich, Chr. Hansen) was employed on the fermented samples. The samples were characterized by physical and chemical, microbiological and sensory parameters. The BLC sample showed the presence of yeasts and coliform counts, but the counts indicated that it was suitable for consumption in 28 days time. The BL presented average coliform counts above the limit established by the law after 21 days of refrigerated storage. The presence of lactic bacteria and CO2 and their effects on lower proteolysis indexes, lower pH values and higher acidity values were correlated with signifi cant inhibitory effect of contaminated microorganisms in the BLF and BLFC. The carbonation was not stimulatory for the growth of lactic crops, mainly in the genus Bifi dobacterium spp. and Streptococcus spp. The BLF drink presented greater sensory acceptance and purchase intention test results, however the carbonated beverage presented positive results, with mean values greater than 50% in the acceptance tests with potential inclusion as sensory differential in dairy beverages. Just BLFC drink was considered potentially probiotic, by presenting minimum counts of Lactobacillus spp. during storage. Further studies should be conducted with the technology of carbonation, since it has been proven the correlation of the presence of CO2 with inhibitory effect of contaminated microorganisms and lower physical and chemical changes of dairy beverages.

Análise energética de cerveja eleborada com mel

The objective of this study was to characterize energetically beersmade withhoney. The tests of beer production weremade withninetreatments,threecombination of the originalextract concentrations (11, 13and 15 °Brix) and threepercentagesof honeyin the wort formulation(0, 20 and 40%).The experimentwas completely randomizedwith two replications, totaling eighteenplots.Themashingprocesswas performed byinfusion, with honey added in the boiling step. After clarified, the wort had its extract contents corrected with the addition of filtered water and was inoculated withlowfermentation yeast .The fermentation occurred at 10 ° C. The beer was manually bottled and stored in a freezer at 0 °C for 15 days, formaturation. The beers were chemically analyzed on proximate composition (moisture, protein, lipid, ash, and carbohydrate), alcohol content (% m / m) and then calculated the energy value. The results ofchemical analysis andenergetic valuesof the beerswere subjected to analysisof variance (F test) and the means werecompared byTukey testat 5% probability. The commonbeershad the lowestenergy value (31.05 to 31.95 kcal100g-1) in relation toextra(36.42 to 38.42 kcal100g-1) and strong(38.20 to 40.17 kcal100g-1) beers. Theincrease in the original extractin beerraises theircaloric values. The presenceof honeyin the formulationincreasedthe energetic valuesincommon andextrabeersand decreasedin strong.The levelsof alcohol andcarbohydratewere predominant in thebeer energetic values,beingpossible to observeadirect relation amongthese components ofbeer and theircaloric value.

Caracterização química e sensorial de bebida mista de soja e uva

The aim of this study was to produce mix beverages of grape juice and soybean hydrosoluble extract (SHE) in laboratory scale. The raw materials were soybean (variety BRS 213), grape (species Vitis labrusca, variety Niagara Rosada), citric pectin, water and sugar. The mix beverage was produced with different proportions of SHE and grape juice (1:1; 1:1.5 and 1:2; respectively; m/m) and different soluble solids concentrations (10, 12 and 14 °Brix) obtained by adding granulated sugar (sucrose). Soybean hydrosoluble extract, grape juice and mix beverages were chemically analyzed (humidity, ash, protein, lipids, carbohydrate, reducing sugars, total reducing sugars, sucrose, titratable acidity and pH). The mix beverages were sensorial analyzed through the acceptance test (hedonic scale). The results of chemically analyzed were expressed as mean and standard deviation and the results of sensorial analyzed were submitted to variance analysis and the means were compared using the Tukey test at 5% of probability. The pH of mix beverages was lower than 3.9, without addition of acidulants. Sugar addition to mix beverages (10; 12 and 14ºBrix) increased the levels of soluble solids, total reducing sugar and carbohydrates, but it did not interfere in the reducing sugar concentration. The increased proportion of grape juice in mix beverages allowed observing the elevation of titratable acidity and reducing sugars levels, as well as the pH reduction. The increase of grape juice in mix beverage did not interfere in the acceptance of mix beverages. The more sweetened beverages were preferred by the sensory panel.
