Summary: This study evaluated the feasibility of encapsulating edible oils with antioxidants in a natural protein matrix using the spray-drying method and demonstrated long-term stability of microparticles. Factors such as microencapsulation, antioxidant addition, and the type of oil all influenced the oxidative stability of the oils. Hydrophilic antioxidant PG was found to increase oil stability over the storage period, while lipophilic antioxidant alpha-T had a pro-oxidant effect.

Summary: Freezing is a common food preservation method, but it often causes irreversible changes that affect the quality of food. Isochoric freezing, on the other hand, has the potential to retain the quality properties of food. Understanding the concept and application of isochoric freezing is necessary to investigate its effect on food quality.

Summary: The study found that different preservatives, freezing times, and analysis temperatures can influence the composition of milk protein fractions. Samples without preservatives had the highest protein content, while Bronopol-preserved milk had the lowest. Prolonged storage under freezing conditions had a negative impact on milk protein fractions. The analysis temperature significantly affected the different protein fractions.

Summary: In remote or resource-limited areas where the cold chain cannot be maintained, it is challenging to store and preserve biological samples like faecal specimens. This study evaluated the suitability of three commercially available filter cards for long-term storage of faecal samples containing common diarrhoea-causing enteric protozoan parasites, showing that these cards can be compatible with molecular methods for up to six months at room temperature.

Summary: In this study, a conjugate modelling approach was used to investigate the momentum, heat, mass transport, and structural deformation during vacuum cooling of steamed bread. The results showed that the three-parameter Maxwell model accurately described the viscoelastic behavior of the bread, and the model predictions were accurate for moisture variation and areal shrinkage. Sensitivity analysis revealed that the deformation model was more sensitive to water transport parameters, particularly the hydrous compressibility factor.

Summary: This study examined the potential significance of extremely low-frequency electromagnetic fields (ELF-EMF) at frequencies ranging from 40 to 70 Hz in inducing biological effects during chilled storage of grass carp. The results showed that treatment with 50 and 60 Hz frequencies significantly increased Ca2+ATPase activity and pH, while reducing the total sulfhydryl content. The treatment at 50 Hz had the most pronounced effects, indicating a potential "window" effect in enhancing the quality of myofibrillar protein during chilled storage.

Summary: This study aimed to investigate how different frequencies of electromagnetic field (EMF) affect the freezing of grass carp tissue. Results showed that treatment with frequencies between 200 and 400 Hz significantly increased the initial freezing point, while the phase change duration remained unchanged. The application of EMF also led to reductions in ice areas and crystal sizes. Overall, these findings suggest that frequencies between 200 and 400 Hz are effective in improving the freezing process with the assistance of electromagnetic field.

Summary: Exploring reliable and efficient methods for evaluating food safety is crucial due to the food safety issues. In this study, a ratiometric test strip using D-penicillamine capped silver nanoclusters (DPA-AgNCs) and bimetallic gold/silver nanoclusters (AuAgNCs) was proposed as a real-time and visual monitoring system for food freshness. The developed test strip showed good response and sensitivity for volatile basic nitrogens (VBNs), with a limit of detection (LOD) of 0.51 mu M and 0.08 ppm for spermidine and ammonia hydroxide, respectively. It was successfully applied for non-contact and visual evaluating and monitoring VBNs in shrimp samples.

Summary: A novel strategy combining a pH-responded colourimetric sensor array (CSA) with machine learning models was developed to effectively monitor beef freshness in real time by detecting total volatile basic nitrogen (TVB-N) contents. Sequential forward selection (SFS), random forest (RF), and principal component analysis (PCA) were used to extract effective colour features sensitive to changes in TVB-N contents. Linear regression (PLSR), as well as nonlinear regression models (RFR and SVR), were established to predict TVB-N values based on full and effective colour features. The RF-SVR model showed the best performance, with a determination coefficient of prediction (Rp2) of 0.9596, a root-mean-square error of prediction (RMSEP) of 1.89 mg/100 g, and a relative prediction deviation (RPD) of 4.98. The CSA based on the RF-SVR model was applied to quantify beef freshness at 4 degrees with validation using a standard method. This study demonstrated that the CSA, combined with machine learning, can objectively and nondestructively monitor TVB-N contents for evaluating beef freshness.
