Herein, ultraviolet B (UVB) persistent luminescence phosphors containing SrAl 12 O 19 : Ce3+, Sc3+ nanoparticles were reported. Thermoluminescence (TL) spectrum analysis reveals that the shallow trap induced by Sc3+ co-doping plays an important role in photoluminescence persistent luminescence (PersL) development, while the deep trap dominates the generation of optical stimulated luminescence (OSL). Owing the appearance of deep trap, the OSL is observed under light (700 nm - 900 nm) excitation. UVB luminescence exerts good bactericidal effects on pathogenic bacteria involved in the process of food spoilage. Thus, the smart window with SrAl 12 O 19 : Ce3+, Sc3+/PDMS produces UVB PersL to efficiently inactivate Escherichia coli and Staphylococcus aureus. In addition, the presence of the smart window delays the critical point of pork decay, and greatly reduces the time of pork spoilage. It maximizes the convenience of eradicating bacteria and preserving food, thus offering a fresh perspective on the use of UV light for food sterilization and preservation. • PL, PersL and OSL in the UVB range are demonstrated in SrAl 12 O 19 doped with Ce3+. • The shallow trap induced by the Sc3+ co-doping plays an important role in PersL. • The deep trap dominates the generation of OSL. • Smart window can inactivate Escherichia coli and Staphylococcus aureus. • This smart windows dramatically delay pork spoilage.

• MVD mushroom stipes showed higher moisture contents, ε ' and ε ' ' values than caps. • MVD mushroom caps displayed higher water evaporation and rehydration rates. • The centre area of the MVD mushroom slice had the highest temperature. • The more porous structure in the MVD cap led to its higher mass transfer rates. This research work aimed to investigate the effects of microstructures, dielectric property and temperature distributions on drying feature difference between the mushroom cap and stipe during the microwave-vacuum drying (MVD) process. Near-infrared hyperspectral imaging (NIR HSI) was employed to visualize distribution maps for moisture content (MC), dielectric constant ε ' and dielectric loss factor ε ' ' of mushroom slices during the MVD process. Infrared (IR) thermal imaging was used to evaluate the temperature distribution of the mushroom slices. Results demonstrated higher MC, ε ' and ε ' ' values in MVD mushroom stipes. Nevertheless, the centre area of the mushroom slice showed the highest temperature, while the MVD mushroom cap displayed a more porous structure. The effect of microstructure could encounter effects of dielectric properties and temperature to cause higher water evaporation in the MVD cap. This work highlights the novelty to combine different detection techniques to investigate the effects of microstructures, dielectric property and temperature distributions on drying patterns of mushroom slices.

• MVD ginger slices showed higher shrinkage rates and hardness than splits. • MVD ginger splits had higher rehydration rates than slices at the beginning. • The surface layer of MVD ginger slices showed more porous than that of splits. • A more uniform moisture distribution was found in MVD original ginger slices. This study aimed to investigate the difference between ginger slices (vertically cut) and splits (horizontally cut) during microwave-vacuum drying (MVD) procedures. MVD ginger slices showed a higher shrinkage rate and a higher hardness value, with a more porous structure of the surface layer. MVD ginger splits had higher rehydration rates at the first 15 min of the rehydration. Nine optimal wavelengths were selected by regression coefficients (RC) from the partial least squares regression (PLSR) model based on the raw data. A simplified PLSR model based on optimal wavelengths showed a good performance with a coefficient of determination in prediction (R p 2) of 0.973 and a root mean square error in prediction (RMSEP) of 4.63%. Texture features of grey level co-occurrence matrix (GLCM) of moisture prediction maps demonstrated a more uniform moisture distribution in MVD ginger slices than that in splits in the original geometry.
