Standard tonic water

Objectives

• To increase the carbonation levels of tonic water

Sample Preparation

• Tonic without CO₂Sustain® was re-carbonated on an Armfield carbonator to 8.5g/l (sample A)
• Tonic with 0.2g/l CO₂Sustain® was re-carbonated on an Armfield carbonator to 8.5g/l (sample B)
• Samples were filled into glass bottles and refrigerated overnight

Test Methods

• A sensory panel (8 people) completed a blind taste test where the participants were asked whether the Sustain sample (A) was:
  • Less fizzy than sample B
  • Fizzier than sample B
  • No difference
• The bottles were then tested for carbon dioxide loss on pouring
• The 275ml sample bottle was poured gently into a glass vessel on an analytical balance
• The weight of CO₂ lost was recorded over a 30-minute period

Results – Sensory

• Of the 8 panelists, 8 people recorded the sample with CO₂Sustain® as being fizzier
• Nobody recorded no difference

Results – Carbon Dioxide Retention on Pouring

• The graph shows that the sample with CO2Sustain® retained more CO2 when poured
• At the point of pouring, the sample without CO2Sustain® dropped to 6.5g whereas the drink with CO2Sustain® only dropped to 7.1g
• The final level of carbon dioxide retained after 30-minutes was 1.4g extra with CO2Sustain® (31%)

Conclusions

• • • The addition of CO₂Sustain gives the consumer a much fizzier drink experience over 30-minutes
