How will you determine if harmful micro organisms are produced in bread or fruit?
Answers
Answer:
Bread is made from cereal grains ground into flour. Leavened bread is softer due to the action of yeast, which is a fungus. Yeast (Saccharomyces cerevisiae) contributes both to the texture and flavour of bread. A dough is made by mixing yeast with flour, salt and water. The yeast ferments sugars in the mixture to make alcohol and bubbles of carbon dioxide. The gas gets trapped in the sticky proteins of the dough and causes it to rise, whilst the alcohol is converted to compounds which impart taste to the bread as it is baked in the oven. Bread-making is an aerobic process and the main products of the fermentation are carbon dioxide and water, rather than alcohol, as produced in beer and wine manufacture.
