Energy Drink

Objective

• 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 0.4g/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®

Conclusion

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