Novel Technologies to Improve the Flavour of Coconut Water

Overview

This offering addresses off-flavour challenges in coconut water through a science-led approach combining flavour chemistry, sensory analysis, and consumer science. The work targets the identification, quantification, and removal of problematic volatile compounds that negatively affect beverage quality, while controlling enzymatic and oxidative pathways that generate off-flavours during storage. The result is a more appealing coconut water product aligned with consumer preferences.

Technical specifications

Key capabilities and approaches:

• Identification and quantification of flavour-active compounds using GC-MS/MS, GC-O, and A-TEEM spectroscopy, alongside ICP-MS for mineral profiling
• Spinning cone flavour fractionation to separate and recombine volatile flavour fractions for optimised ratios
• Non-volatile fractionation through membrane separation techniques
• Removal of off-flavours using adsorbents such as activated carbon and cyclodextrins
• Enzyme inactivation and oxidation pathway control to mitigate ongoing off-flavour generation
• Rapid shelf-life evaluation at 5 °C, 25 °C, and 45 °C, with and without light, free metal ions, and antioxidants
• Concurrent sensory analysis to determine rejection thresholds, cross-modal flavour interactions, and consumer product liking models

Team strengths:

• Extensive experience across beverage industries including coffee, wine, beer, and spirits
• Collective expertise of 74 years, 443 peer-reviewed publications, and 115 PhD researchers supervised
• Proven track record delivering industry-relevant flavour solutions for complex beverages

Technology readiness level

This is a research-based service offering ready for sponsored research collaboration. Validation activities are planned to include compound identification, fractionation trials, adsorbent removal testing, shelf-life studies, and sensory evaluation. The team is positioned to work with coconut water producers to trial and refine flavour optimisation strategies, with expertise drawn from world-leading flavour research laboratories in Australia and the UK.
