Answer 1

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..

Fermentation occurs in some bacteria, yeasts and in the muscles during heavy exercise. Yeast (fungi) converts sucrose into ethyl alcohol..

Pasteurization or pasteurisation is a process in which packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
