competition due to their uniqueness and outstanding quality. Most of the breads are European in style‚ including Sourdough‚ Miche (a traditional French whole wheat bread)‚ and Sourdough Rye. These breads are made by the sourdough method which uses no added yeast. This method imparts a rich flavor‚ which can be tangy or mild‚ as well as a toothsome inner crumb and a crackly crust. By using this method‚ a skilled baker can create truly delicious breads without added fats or sugars‚ making many of Breadcrafter’s

nutrients. Molds (and mildew) are fungi. Fungi are neither plant nor animal but‚ since 1969‚ have their own kingdom. The fungi kingdom includes such wonderful organisms as the delicious edible mushrooms‚ the makers of the "miracle drug" penicillin and the yeast that makes our bread rise and our fine wines ferment. B. STATEMENT OF THE PROBLEM 1. Can bread molds grow fast in an open environment? 2. Can bread molds grow fast in a closed environment? 3. How does temperature affect the growth

data. Finally‚ special thanks go to my aunt and teacher Mr.Williams who guided me every step of the way through this exercise. Introduction Alcohol is created when grains‚ fruits‚ or vegetables are fermented. Fermentation is a process that uses yeast or bacteria to change the sugars in the food into alcohol. Fermentation is used to produce many necessary items — everything from cheese to medications. Alcohol has different forms and can be used as a cleaner‚ an antiseptic‚ or a sedative. So if

Molds are fungi that are found everywhere – both indoors and outdoors all year round. The terms fungi and mold are often used interchangeably‚ but mold is actually a type of fungi. Concern about indoor exposure to mold has increased along with public awareness that exposure to mold can cause a variety of adverse health effects. There are many thousands of species of mold and most if not all of the mold found indoors comes from outdoor sources. It seems likely to grow and become a problem only when

Vegetable is important commodities to human being because it provides vitamin and minerals. Due to the public concern regarding the importance of vegetables in their life‚ the public demand on the vegetables increase. For example‚ carrot‚ tomato and chilli are most demand among Malaysian adult. However‚ vegetables are susceptible to the microbial infection due to its pH that closer to the neutral pH. Generally‚ Alternaria‚ Fusarium‚ Penicillium‚ Aspergillus‚ Geotrichum and Botrytis are common post-harvest

Title : Measuring the rate of oxygen uptake. Objectives : 1. To demonstrate the uptake of oxygen in respiration. 2. To measure the rate at which an organism respires. 3. To learn how to set up the apparatus for respirometers. Introduction : Respirometer A respirometer is a device that been used to measure the rate of respiration of a living organism. This can be measured by calculating the rate of exchange of oxygen and carbon dioxide. A simple respirometer designed to measure oxygen
