Cola

Objective

• To increase the fizziness of Cola for a better consumer experience

Sample preparation

• Cola without CO2Sustain® were re-carbonated on an Armfield carbonator to 8g/l (sample A)
• Cola with 0.1g/l CO2Sustain® were re-carbonated on an Armfield carbonator to the same carbonation level (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 being fizzier
•  No one 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 5.7g whereas the drink with CO2Sustain® only dropped to 6.6g (16% improvement
• The final level of carbon dioxide retained after 30-minutes was 0.8g extra with CO2Sustain® (19%

Conclusion

• The addition of CO2Sustain® allows the Cola to be carbonated at a lower level whilst still giving the consumer a fizzier experience over 30-minutes
