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). 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.
