Industrial preparation of carbonated
wateror soft drinks
Introduction: soft drink is also known as club soda, soda water, sparkling water, carbonated water, seltzer water, or fizzy water.
Definition: it is water into which carbon di oxide gas under pressure has been dissolve, a process that cause the water to become effervescent. and the process is called carbonation.
Name history: 1950s the term soda or sparkling water and seltzer water gained favor.The term seltzer is derives from German town “seltzer" which is renowned for its mineral spring.
Early history:in early days water was most obvious source of hydration .but it was contaminated by micro organism. so in 1320 they started boiling and flavoring of water by using different herbs.
Discovery• In 1767 Joseph Priestley invented carbonated
water in Leeds England.• In 1772 Priestley published a paper entitled
impregnating water with fixed air.• In 1771 a chemistry professor Torbern Bergman
invented the process of carbonation.• In 1822 carbonated water was introduced in
Kolkata India.• In 18th century j.j Schweppes started a company
of carbonated water based on the process discovered by Joseph Priestley in Geneva

Soft drink industry in pakistan
• In Pakistan all the famous brands are manufacture here like coca cola ,Pepsi ,fanta,dew etc
• They are licensed by foreign country.• Gourmet ,amrit cola are those brands which
manufactured in Pakistan.
Basic ingredient• Carbon di oxide:• CO2 is the most important ingredient of the
soft drink.• It gives sour taste and when bottle is opened
it give hissing sound.• Its ph ranges from 3.2-3.7 and it has sour
taste • It removes contamination.
Content present in flavored soft drink
• 7up / spirite:• Cane sugar • Sodium citrate• Sodium benzoate• Aspartame• Lemon essence• Citric acid • Bottle water refill• Ace-k
Fanta ,marrinda or taste orange• Cane sugar• Sodium citrate• Sodium benzoate• Stevioside• Potassium sorbate• Citric acid• Bottle water refill• Ace-k
For cola type• Cane sugar• Phosphoric acid• Sodium benzoate• Sodium cyclamate• Caffeine• Citric acid• Whole color full soda• Bottled water refill• Ace-k
Straw berry type• Cane sugar• Sodium citrate • Sodium benzoate• Citric acid• Strawberry essence• Bottle water refill• Ace-k
Litchy type:• Cane sugar • Sodium citrate• Emulsified essence litchi• Citric acid• Sodium benzoate
bottled water refills• Ace-k
Basic constituent of a soft drink
components• Water• Its is a bland carrier for
other ingredient, also provide hydration.
• Sugar• Contribute in sweetness act
as synergists give balance to flavor.
• Fruit juice• Provide fruit source
identity,flavor,and acidity
Typical use level• Up to 98 percent when high
intensity sweetener are used
• 7-12 percent used
• Usually up to 10 percent as a natural strength.
component• High intensity sweetener:• Provide sweetness calorific
reduction synergist action(aspartame, with ace-k)
• Carbon di oxide :• Provides mouth feel and
sparkle drink.• Acids• Contribute sharpness
sourness and back ground to flavor.
• Flavor• Provide flavor character
identity to drink.
Typical use level• Used depend upon sucrose
equivalence.
• 0.3-0.6 percent
• 0.05-0.03 percent
• Artificial and natural identity
• 0.1-0.5 percent
Component Typical use level
• Emulsion• flavor color cloud • Give cloudy effect to drink.ColorNatural or synthesized.PreservativePrevent from microbial attackAnti oxidants Like absorbic acid ,prevent
from oxidation.
• 0.1 percent
• 0-70 ppm
• Statutory limits apply 250 ppm
Less than 100 ppm
Components Typical use level
Quillia extract/saponinsProvide heading foam.HydrocolloidsProvide mouth feel shelf
life stabilityVitamins/mineralsUsed in healthy living
drinks.
• Up to 200 mg/l
0.1-0.2 percent/gmp
ADI applies.
Water purification• Water is main component of a soft drink.• 85-95 percent is used.• For manufacturing treated water is used.
• Requirements• Water should be free from
high levels of element and mineral salts.• Objectionable taste and odour. • Organic material.• It should be clear and color less.• Free from dissolved oxygen • Sterile, that is free from micro organisms.
Manufacturing process
• Washing and cleaning of bottles.• Checking of bottles (if glass bottles)• Preparation of syrup.• Filling of bottles with syrup.• Carbonating of filled bottles.• Quality checking of prepared batch.• Capping process.• Packing and storing.
Hard facts• Scientific studies reveal that 1-1.5 lit of soft drinks a day can rise risk of numerous health problems.
• Tooth decay• Obesity• Effect on kidney• Effect on skin• Effect of bone• Mal nutrition• Effect of caffeine
contain benzene
Are they advantages or disadvantages?
• In 1906 pure food and drug was passed.• 1922 official claimed • There are some points reveal real side
effects of soft drink.• Used to clean blood on road sfter accident.• For cleaning of toilet.• Rust spot cleaning• Cleaning of corrosion from battery
terminals• To remove grease from cloths.• Cleaning of engine.
