Summary: This study investigated the effect of agitation speed on the freezing process of an aqueous sucrose solution. It found that higher agitation speed caused the frozen samples to melt at a lower temperature and increased the degree of supercooling. Additionally, the agitation speed affected the time scale for the nucleation and growth of ice crystals.

Summary: This paper investigates the effect of weak magnetic fields on the freezing process of deionized water and physiological normal saline. The results demonstrate that different magnetic field strengths have different effects on aqueous solutions. Only a specific strength of the magnetic field has a positive effect on the freezing process, and the effect on normal saline is generally better than that on deionized water. A magnetic field strength of 150G positively influences the supercooling degree and supercooling time of saline. In beef freezing experiments, the magnetic field is found to not only promote but also inhibit the freezing process, with the addition of a fan affecting the freezing effect. Magnetic field strengths of 40G and 50G significantly promote beef freezing, while a strength similar to 150G (100G) has a significant inhibitory effect.

Summary: The application of ultrasound in the freezing process can reduce supercooling effects and save energy. Intermittent ultrasound application at power levels of 3.52 W and 8.25 W was found to be more effective than constant-power application. Energy savings of 12.4% and 10.8% were observed with intermittent ultrasound experiments at 3.52 W and 8.25 W power levels, respectively, compared to processes without ultrasound.

Summary: The present study investigated the effects of isochoric supercooling and freezing on the qualitative attributes of pomegranates, including color, texture, and phytochemical components such as anthocyanins and ascorbic acid. Isochoric supercooling was found to retain color and texture, increase anthocyanins and ascorbic acid content, and inhibit bacterial growth. Isochoric freezing, on the other hand, was the most effective method for inhibiting microbial growth and increasing ascorbic acid content. However, it caused some loss in texture. Isochoric supercooling was also effective in preserving fresh-cut arils, minimizing texture and color loss.

Summary: Aggregates, as a form of materials, offer modified or new properties compared to their molecular elements, which make them advantageous. Molecular aggregation can cause changes in photoluminescence properties, leading to aggregation-causing quenching (ACQ) or aggregation-induced emission (AIE) effects. These changes have potential applications in food hazard detection by combining recognition units. This review summarizes aggregation mechanisms, structural characteristics of fluorescent materials, and their applications in food hazard detection with or without recognition units, as well as discusses the future trends in developing aggregate-based fluorescence sensing technology.

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.
