Energy Drink

  • Drink: Full sugar energy drink
  • Ojective: To increase the carbonation level
  • Date: February 24


  • To increase the carbonation level of energy drink

Sample preparation

  • Energy drink without CO2Sustain® was re-carbonated on an Armfield carbonator to 6.0g/l (sample A)
  •  Energy Drink with 0.2g/l CO2Sustain® was re-carbonated on an Armfield carbonator to 6.0g/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 330ml 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 4.8g whereas the drink with CO2Sustain® only dropped to 5.1g
  • The final level of carbon dioxide retained after 30-minutes was 0.5g extra with CO2Sustain®


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