Display omitted •Truffle aromatic compounds can be trapped by sunflower oil and honey.•Fresh truffle is more suitable than freeze-dried in a 24 h aromatization process.•Sulphurous attributes were scored highly in fresh truffle home-made products.•Pasteurization is preferable to sterilization to preserve truffle aromatic compounds. Truffles are highly valued by their aromatic properties and can aromatize food products. However, the truffle aroma could be reduced or lost with heat treatments (pasteurization and sterilization) necessary for products security and safety. In this study, sunflower oil and honey were aromatized with black truffle (lyophilized and fresh) using two different concentrations (5 and 10 %) for 24 h and then heat treatments (pasteurization and sterilization) were carried out. Truffle organic volatile compounds from products were investigated by SPME-GC–MS and sensory analysis by trained panel. More than 80 compounds were detected. Some of them were affected differently by heat process depending on the food matrix. Professional tasters scored higher key aromatic attributes such as sulphurous and olive oil in fresh truffle products, regardless the heat treatment applied.
