Soft drinks typically contain carbonated water, a sweetener like sugar or high-fructose corn syrup, and natural or artificial flavorings. They may also include caffeine, colorings, preservatives, and other ingredients. Stabilizers are added to prevent particles from settling. Common stabilizers include brominated vegetable oil, glyceryl ester of rosin, and sucrose acetate isobutyrate. Preservatives like sodium benzoate and potassium meta bisulphate are used to prevent spoilage. Regular consumption of soft drinks can lead to malnutrition, acidity, tooth decay, heart disease, obesity, kidney disease, and financial costs due to healthcare expenses.

4. DEFINITION OF SOFT
DRINKS
 Oxford – “ A non-alcoholic drink” called soft in
contrast to hard – having significant amount of
alcohol
 Wikipedia – “A non-alcoholic beverage typically
containing water and flavoring agent majorly
carbonated and sweetened “

6.  Most of the drinks are liquids in the
colloidal form
The drinks does not settle down even
after prolonged storage

7. Discussion points
 How are the drinks retained as such for
long periods of time without settling down ?
 Do you know that some substance are
added for this purpose ?

8. STABILIZERS
A chemical substance that used in
soft drinks to prevent the particles from
getting settled .
Examples
1. Brominated vegetable oil
2. Glyceryl ester of rosin
3. Sucrose acetate isobutyrate

9. Why chemical substance are
added in soft drinks ?
• For Color
• For Smell
• For Taste

11. PRICERVATIVES
Chemicals that used to prevent damage of food
stuffs
Natural preservatives
Salt , Vinegar , Curd , Sugar
Chemical preservatives
Sodium Benzoate , benzoic acid , Potassium
meta bisulphate

13. DISCUSSION POINT
Dose the regular intake of such
synthetic drinks causes any
harmful effect in our human
body ???????

14. Yes . Of course
Regular intake of soft drink courses
Malnutrition
Acidity
Tooth decay
 Heart diseases
 Obesity
 Kidney diseases
Financial lose
Etc…..

16.  Tooth decay is the softening of your tooth
enamel and refers to the damage of the
structure of the tooth caused by acids that are
created when plaque bacteria break down
sugar in your mouth.
 Soft drinks are lead to develop bacterias in
mouth .

17. A disorder involving excessive body fat
that increases the risk of health
problems.
Soft drinks mainly
compose sugars and
they increases the
body fat .
