  • 9. Basic ingredient• Carbon di oxide:• CO2 is the most important ingredient of thesoft drink.• It gives sour taste and when bottle is openedit give hissing sound.• Its ph ranges from 3.2-3.7 and it has sourtaste• It removes contamination.
  • 10. Content present inflavored soft drink• 7up / spirite:• Cane sugar• Sodium citrate• Sodium benzoate• Aspartame• Lemon essence• Citric acid• Bottle water refill• Ace-k
  • 11. Fanta ,marrinda or taste orange• Cane sugar• Sodium citrate• Sodium benzoate• Stevioside• Potassium sorbate• Citric acid• Bottle water refill• Ace-k
  • 12. For cola type• Cane sugar• Phosphoric acid• Sodium benzoate• Sodium cyclamate• Caffeine• Citric acid• Whole color full soda• Bottled water refill• Ace-k
  • 13. Straw berry type• Cane sugar• Sodium citrate• Sodium benzoate• Citric acid• Strawberry essence• Bottle water refill• Ace-k
  • 14. Litchy type:• Cane sugar• Sodium citrate• Emulsified essence litchi• Citric acid• Sodium benzoatebottled water refills• Ace-k
  • 15. Basic constituent of a softdrinkcomponents• Water• Its is a bland carrier forother ingredient, alsoprovide hydration.• Sugar• Contribute in sweetness actas synergists give balanceto flavor.• Fruit juice• Provide fruit sourceidentity,flavor,and acidityTypical use level• Up to 98 percent when highintensity sweetener areused• 7-12 percent used• Usually up to 10 percent asa natural strength.
  • 16. component• High intensity sweetener:• Provide sweetness calorificreduction synergistaction(aspartame, withace-k)• Carbon di oxide :• Provides mouth feel andsparkle drink.• Acids• Contribute sharpnesssourness and back groundto flavor.• Flavor• Provide flavor characteridentity to drink.Typical use level• Used depend upon sucroseequivalence.• 0.3-0.6 percent• 0.05-0.03 percent• Artificial and naturalidentity• 0.1-0.5 percent
  • 17. Component Typical use level• Emulsion• flavor color cloud• Give cloudy effect todrink.ColorNatural or synthesized.PreservativePrevent from microbial attackAnti oxidantsLike absorbic acid ,preventfrom oxidation.• 0.1 percent• 0-70 ppm• Statutory limits apply 250ppmLess than 100 ppm
  • 18. Components Typical use levelQuillia extract/saponinsProvide heading foam.HydrocolloidsProvide mouth feel shelflife stabilityVitamins/mineralsUsed in healthy livingdrinks.• Up to 200 mg/l0.1-0.2 percent/gmpADI applies.
  • 19. Water purification• Water is main component of a soft drink.• 85-95 percent is used.• For manufacturing treated is used.• Requirements• Water should be free fromhigh 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.
  • 20. 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.
  • 21. Hard facts• Scientific studiesreveal that 1-1.5 litof soft drinks a daycan rise risk ofnumerous healthproblems.
