Ethanol fermentation

Introduction: Based on preliminary research, the hypothesis of the present study was that at temperatures higher or lower than 40 degrees Celsius fermentation is inhibited. Alcoholic fermentation is used in food production such as brewing, winemaking, and baking (Campbell). Thus optimizing fermentation and understanding the effect of various environmental factors can have important economic and social benefits. The production of CO2 is being assessed to show the rate of fermentation at certain time intervals. This data could be used to optimize fermentation of yeast by finding the optimum temperature. Based on the research done by Yan Lin et al there were evidence to suggest that “20 -35 degrees is the ideal range for fermentation and at higher…

(Hayden, Canuel and Shanse), demonstrate the technological viability of brewing. Unlike the arduous process of fine grain grinding involved in breadmaking, brewing would be a more accessible and expedient way for processing these grains. What was the motivation to brew beer? Conventionally, it has been believed that beer was preferred as a safer liquid to drink during times when water sanitation was unreliable (Bamforth). With low pH (3.8–4.6) as well as moderate ethanol content, the…

Fermentation has been used by mankind for centuries to make useful products such as cheese, breads, yogurts and alcohol beverages. During fermentation, some strains of yeast decompose sugars to derive energy, and in the process they produce ethanol as a waste product. When bread dough is being made, yeast is added to make dough rise. This occurs because the yeast ferments sugar releasing carbon dioxide which causes the dough to rise and creates holes in the bread. This carbon dioxide released…

Abstract: Fermentation of sucrose with brewer yeast catalyst was successfully conducted to yield ethanol with 70.2 % conversion of sucrose. Based on the graph of Refractive Index vs % ethanol (v/v), 32.8% of ethanol was determined to be in the distillate solution with corresponding Refractive Index of 1.3555 Statement and purpose The purpose of this experiment was to determine the % of ethanol (v/v) in the resulting solution and the % conversion of sucrose Introduction The fermentation 17.1 g…

Loire Valley in France but is growing popularly in South Africa. It can be made from sparkling wine to sweet dessert wines. It has floral aromas, and flavors of ripe apple, lemon, pear and honeydew. It can blend well with Mediterranean foods, sushi and veal. • Müller-Thurgau – a white grape wine variety originally from Switzerland. These wines are commonly for everyday drinking, light, youthful and refreshing. • Bold and Dry Types of wine that are hard and mostly undergoes the process of oak…

Thursday, January 5, 2017 I was on vehicle patrol traveling westbound on Water St passing the ferry terminal when I observed a vehicle traveling towards me that was very close to the center line of the road. I further observed that the vehicle was over the double yellow center line, so I steered to the side of the road and let the vehicle pass. I turned on the vehicle (a dark colored SUV) and had to accelerate to catch up the vehicle. As I was doing this I observed the vehicle again drive on…

Today, Louis Pasteur’s name has become almost synonymous with germ theory, vaccination, and immunology. His accomplishments include not just disease management, but include also the saving of certain business and national economies. For example, one of Pasteur’s first successes was in identifying the nature of fermentation, and showing the importance of yeast as a catalyst. Because of his work, distilleries in Lille, France were able to produce wine more regularly once Pasteur had discovered the…

Critical Issues and Recommendations “Craft Beer” Feel While BBC has reaped tremendous success in the market place as the creator of the craft beer segment, there are those that believe that the company is too large and too well known to be referred to as a “craft” beer. Millennials craving for offerings that are organic, local, authentic, cool, and new aren’t getting what they want from the Samuel Adams brand and have started to turn their back on the company (Crouch, Wasted: How the Craft-Beer…

There are two yeasts genera that frequently isolated from pollen and honey of stingless bee hive, which includes Candida and Starmerella (Rosa et al., 2003; Teixeira et al., 2003; Daniel et al., 2013). Rosa et al. (2003) also reported that other genera of yeasts have been found in propolis, adult bees, the colony trash deposit area, and less in the honey. According to Menezes et al. (2013), yeasts have the important potential roles for the meliponine colonies as similar as the bacterial roles.…
