Small Peltier element to detect real-time heat flux between apple and environment during postharvest storage

•Heat flux sensor based on Peltier element (PE) was introduced.•Apple was used to validate heat flux during cooling, temperature fluctuations and re-warming.•PE results reliably capture minor heat fluxes with small temperature differences (
