Transcript The Fermentation of Fruit

The Fermentation of Fruit
By Emily & Tess
 Fermentation can be found in nature (fruits) and is used to
make alcohol. Starches and sugars are converted to
alcohol and carbon dioxide from the enzymes in yeast.
This process is called alcoholic fermentation. Fruits will
start with sugar (glucose) and when given energy (sun)
will ripen and convert to ethyl alcohol and carbon dioxide.

Rearrangment
Glucose= 6 carbons 12 hydrogen and 6 oxygen
Glucose breaks down into 4 atoms, 2 ethyl alcohols and 2 carbon dioxides
2 carbon dioxides= 2 carbons and 4 oxygen
2 ethyl alcohols= 4 carbons, 12 hydrogen and 2 oxygen
All together all 4 molecules contain the same amount of atoms as one glucose molecule
Scientists and History
 The actual formula has 12 reactions but for this
presentation we have used the simplified version
 In the 1930’s 2 German biochemists, G.Embdem &
O.Meyerhof worked out the sequence of reactions of
how glucose ferments.
Process & Use
 Fermentation can be used to make alcohol like wine,
beer or distilled alcohol (vodka)
 Large vats like these are used in the fermentation
process to brew beer.
Chemical Change
 Fermentation of fruit is a chemical change
 Although fermentation is a chemical change it
shows physical changes
 Fruit will start out unripe and hard and then as the
process progress’ the fruit will get squishy and
juicy.
 Some animals can even get “drunk” off of overly
ripe fruit
