Abstract
To overcome defects of polyvinyl alcohol (PVA) and expand its applications in food preservation, PVA/Ag@SiO2 nanocomposite films were prepared using the solution intercalation film‐casting method. Transmission electron microscopy, X‐ray diffraction, and UV‐visible absorption spectra were applied to confirm the synthesis of the nanoparticles (NPs). Effects of Ag@SiO2NPs on physicochemical...
Abstract
Time–temperature indicators (TTIs) can monitor the quality and safety of food. A new temperature–time point comparison method was proposed to match TTIs with food. This method omits the step of calculating activation energy (Ea). It only compares the difference between TTI response time and food shelf life to determine their matching degree. Taking gold nanoparticle‐based TTIs and muffins...
