Reduced Sugar Lemonade

  • Drink: Reduced sugar lemonade
  • Objective: To increase fizziness using less CO2
  • Date: September 2022

Objectives

  • To increase the fizziness of reduced sugar lemonade whilst using less CO2

Sample Preparation

  • Reduced sugar lemonade without CO2Sustain® was re-carbonated on an Armfield carbonator to 8g/l (sample A)
  •  Reduced sugar 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



Reduced Sugar Lemonade - carbonation retention

  • 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
