4. What is fermentation?
Answers
Explanation:
the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat
Answer:
Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen
Equation
Alcoholic fermentation converts one mole of glucose into two moles of ethanol and two moles of carbon dioxide, producing two moles of ATP in the process. The overall chemical formula for alcoholic fermentation is: C6H12O6 → 2 C2H5OH + 2 CO. Sucrose is a sugar composed of a glucose linked to a fructose.
Ideal temperature
According to Gene Spaziani, the optimal temperature range for fermentation is between 42 °F and 50 °F (one of the lower ranges for white wines).
What Are the 3 Different 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. ...
Acetic acid fermentation.
Stages
Fermentation is usually divided into three stages: primary, secondary, and conditioning (or lagering).
