To determine what conditions make dough rises best Apparatus and materials Flour Yeast Warm water Sugar Mixing bowl Two (2) beakers Measuring cup Spoon Diagram of Apparatus Method 1. Take a measuring and measure 1 and ½ cups of warm water 2. Add yeast then sugar (this is used to activate the yeast. The yeast uses the sugar and water to create carbon dioxide and raise the bread) 2. Add the yeast mixture to the mixing bowl along with ¾ of flour 3. Mix the ingredients with a wooden

Louis Pasteur And The Alcoholic Fermentation Abstract: Louis Pasteur (1822-1895) was a French chemist and microbiologist known for his discoveries in the field of vaccination‚ pasteurization and microbial fermentation. His discoveries have saved many lives and his contributions to science‚ technology‚ and medicine are nearly without precedent. This paper will focus on one of the aspect of his work that relates mostly to chemistry: the alcoholic fermentation. Louis Pasteur:

Objectives 1. Define Roccal = green‚ liquid disinfectant. Pathogen = an agent which causes disease. Wet Mount Slide = a microscope slide of a liquid specimen covered with a cover glass. Yeast = a single celled fungi. Budding = a true characteristic method of asexual reproduction among yeasts where budding of a new cell from a parent cell can be observed. Mold = multicellular masses of filamentous fungal growth. Hyphae = individual filaments of mold‚ generally comprised of more than

THE PROCESS OF FERMENTATION THROUGH DIFFERENT KINDS OF SUGARS In order to produce ethyl alcohol fermentation‚ we had to determine what sugars used‚ such as glucose (a single sugar) sucrose (table sugar) and lactose (milk sugar) will react with yeast to produce ethyl alcohol fermentation. My hypothesis is that the sugar lactose would produce the highest amount of bubbles and ferment. INTRODUCTION: The significance of fermentation is a lengthy process that has been practiced by humankind

this way. I just checked out the article for mold on Wikipedia. It said mold grows best at lower temperatures. Try putting the moist loaf of bread in the fridge. The mold will probably grow faster. Yeast is a form of fungus‚ too. When bread is made‚ yeast is added to the dough to make it rise. Yeast loves dough; it is the perfect place to eat‚ grow and multiply.

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

3.1 What are the technical descriptions of the products or services? The proposed product is called “Micro Bignay Wine”. The product is a fruit wine made out of bignay fruit‚ yeast and sugar. Through the fermentation yeast serves as the catalyst that changes the sugar into alcohol. Bignay has its health benefits. It is rich in anti – oxidants and anti – carcinogenic properties. It is highly nutritious and has a number of medicinal properties. Wine is also a part of relaxation and enjoyment with

INTRODUCTION Microorganisms such as bacteria‚ fungus‚ mold‚ and yeast are present and common in almost every environment on earth. The normally microscopic organisms can easily be seen using differing types of agar‚ which creates an ideal environment for the organisms to form colonies‚ which are groups of hundreds of organisms that can be seen with the naked eye. In order to see individual microorganisms‚ it is necessary to use the magnification of a high-powered microscope. These techniques

process‚ as a microorganism breaks a compound down into smaller parts during this type of fermentation. Gibson‚ M‚ 2010‚ The Sommelier Prep Course‚ John Wiley and Sons 5 The “Formula” for Alcoholic Fermentation Sugar + Yeast = Ethanol + Carbon Dioxide + Heat • So‚ when yeast comes in contact with sugar‚ it consumes the sugar molecules‚ breaking them down into two major waste products: ethanol and carbon dioxide. The process also produces heat due to the yeast’s metabolic activity. Gibson‚ M‚ 2010

one rubber stopper‚ one bubbler‚ one measuring beaker‚ 2 ml of yeast‚ 10 ml of warm water‚ and 30 ml of corn syrup. The first step we took was taking the measuring beaker‚ measuring 10 ml of warm water‚ and adding the 10 ml of warm water to the fermentation bottle. We then took the measuring beaker again‚ measured 2 ml of yeast‚ and added the 2ml of yeast to the warm water in the fermentation bottle. After that‚ we mixed both yeast and water gently until it was thoroughly dissolved. Then we took
