Lemonade

Objectives

• To increase the fizziness of lemonade whilst using less CO₂

Sample Preparation

• Lemonade without CO₂Sustain® was re-carbonated on an Armfield carbonator to 8g/l (sample A)
• Lemonade with 0.1g/l CO₂Sustain® was re-carbonated on an Armfield carbonator to 7.5g/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 participants drank directly from the bottle
• 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 still 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 6.2g whereas the drink with CO2Sustain® only dropped to 6.4g
• The final level of carbon dioxide retained after 30-minutes was 0.5g extra with CO2Sustain® (11%)

Conclusion

• The addition of CO₂Sustain® gives the consumer a fizzier drink experience over 30-minutes and reduces CO₂ usage
