Our approach
Given that the ingredient was already in solution, we determined that a beverage would be the best way to deliver it to trial participants and our client requested a 65ml shot format.
Our Product Development Team first developed a simple, water-based beverage formula, containing flavours, acids, preservatives and sweeteners. We masked the ingredient’s strong bitter taste and other off notes by developing a citrus and ginger flavour blend which, along with sweeteners, delivered a more pleasant taste profile.
The beverage shot also needed to have a long shelf life so that it could be stored and administered to participants throughout the four-month clinical trial. However, after the drink was heat processed, acidified and preserved to extend shelf life for as long as possible, we discovered a major issue. A particular acid could not be used as the acidifier because it interfered with analysis of the active ingredient. This was quickly addressed by trialling a replacement acid which maintained the pH, meaning we could then confirm that the active ingredient was still detectable after heat processing.
