Sourdough is the result of a fermentation process in which flour and water are mixed and fermented with microbes‚ especially LAB and yeasts (De Vuyst and Neysens 2005; Corsetti and Settanni 2007a; De Vuyst and Vancanneyt 2007; De Vuyst et al. 2009). Nowadays‚ sourdough is extensively used for the manufacture of a variety of products particularly breads and others‚ such as cakes‚ crackers‚ pizza‚ various sweet baked goods‚ and gluten-free products (Gobbetti 1998; De Vuyst et al. 2009). De Vuyst

Lab: Growing Yeast This experiment will take two days to complete. Background Information: Yeast is a very important group of fungi. The common yeast used in baking bread grows very fast. The basic idea in this lab is that the yeast will use an energy source and in doing so‚ will produce carbon dioxide gas. You’ll measure the amount of carbon dioxide (CO2) released during the growth of yeast. The growth of the yeast stops when the energy source has been used up by the yeast and CO2 production

BREAD MAKING TIME LINE Depending on the type of yeast you are using the steps to making bread will vary. Using the basic bread dough recipe‚ this time line is based on using dry active yeast. I am also basing this time line on the straight dough method which is the direct method of making bread. STEP 1 To make your dough‚ your ingredients must be accurately measured and weighed as well as be the appropriate temperature. Wet ingredients are usually weighed rather than measured to guarantee

The end product ethanol inhibits the action of the enzymes in the yeast. Distillation preformed in order to get more concentrated solutions. Distillation is based on the differences in boiling points of the components of the mixture. Fractional distillation is used to separate the mixture giving 95% ethanol and 5% water

Methods: An observation was made on whether or not the sugars‚ fructose and ribose would be fermented in yeast (Saccharomyces cerevisiae). By looking at the chemical structures of these sugars given in (Figure 1)‚ we looked for anything that might determine the metabolization of these sugars. An equal 6mL (milliliter) sample of 2.5% fructose and yeast suspension was pipetted into a fermentation tube. The same procedure above was performed with the sugar ribose which has a concentration of 2
