optimum temperature for dough growth - Coggle Diagram
optimum temperature for dough growth
Hypothesis
Dough inside a water bath with a controlled temperature of 40 degrees celsius will have the most volume growth
Aim
The objective of this is to discover the optimum temperature for dough growth
Microbes in food production
What are microbes
A microorganism, or microbe, is a microscopic organism, which may exist in its single-celled form or a colony of cells
the three types of microbes found in food are
bacteria, virus, and parasite.
fermentation
The word “ferment” comes from the Latin verb “fervere,” which means “to boil.”
Fermentation is any metabolic process in which microorganisms’ activity creates a desirable change in food and beverages, whether it’s increasing flavor, preserving foodstuffs, providing health benefits, or more
Primary fermentation
In this brief phase, microbes begin rapidly working on raw ingredients such as fruit, vegetables, or dairy.
Secondary fermentation
In this longer stage of fermentation, which lasts several days or even weeks, alcohol levels rise and yeasts and microbes die off and their available food source (the carbohydrates) becomes scarcer
Types of fermentation
Lactic acid fermentation.
Yeast strains and bacteria convert starches or sugars into lactic acid, requiring no heat in preparation.
Ethanol fermentation/alcohol fermentation.
Yeasts break pyruvate molecules—the output of the metabolism of glucose (C6H12O6) known as glycolysis—in starches or sugars down into alcohol and carbon dioxide molecules
Acetic acid fermentation.
Starches and sugars from grains and fruit ferment into sour tasting vinegar and condiments.
