Abstract: Cellulose nanocrystals (CNC) are renewable nano-biomaterials that may be suitable for reducing cold damage in fruit buds to their low thermal conductivity. This study was conducted to evaluate the potential of CNC as a thermal insulation material used in protecting sweet cherry and grape reproductive buds from cold damage. The thermal conductivity measurements were conducted using the transient plane source (TPS) and a Hot Disk TPS 2500 S instrument (from Thermtest Inc.). It was found that the average thermal conductivity for the CNC film was about 0.061 W/mK. This suggests that CNC films of 2 wt% have potential to provide a thermal barrier to protect sweet cherry and grape buds damage from the cold by about 2 – 4°C compared to non-treated buds.
