Summary: The findings suggest that ultrasonic pretreatment is a promising method for improving the drying process of P. eryngii in MHARD, with potential industrial applications. The drying time of P. eryngii was significantly reduced by ultrasonic pretreatment, and the moisture effective diffusivity increased with longer ultrasonic pretreating time. Differential scanning calorimetry curves showed that the drying process was accelerated by ultrasonic pretreatment, enhancing heat transfer efficiency. Meanwhile, scanning electron microscopy images revealed cell breakage and the appearance of irregular holes in the ultrasound-pretreated samples. The rehydration kinetics of dried P. eryngii could be well modeled by the Page model.

Summary: This study investigates the effect of different drying methods on the rehydration quality of icefish. Low-field nuclear magnetic resonance (LF-NMR) is used to compare the rehydration rate, moisture migration, and distribution of icefish dried by cold air and hot air. The results show that cold air drying preserves the muscle fiber structure and protein network better than hot air drying and improves the rehydration quality of icefish. The study provides theoretical and data support for using cold air drying technology in aquatic product processing.

Summary: In this study, a method for accurately detecting oil and moisture content in soybeans was proposed. By introducing two-dimensional low-field nuclear magnetic resonance (LF-2D-NMR), the problem of overlapping component signals that cannot be distinguished by one-dimensional (1D) LF-NMR techniques in soybean detection research was qualitatively solved. The LF-NMR oil and moisture content software was shown to be faster and more accurate than other methods, based on a comparison. The specific identification of oil and moisture signals in soybean seeds using longitudinal relaxation time (T-1) and transverse relaxation time (T-2) successfully addressed the issues of less mobile water, overlapping free water, and oil signals. Therefore, LF-2D-NMR can complement conventional LF-NMR assays, presenting a new method for analyzing and detecting moisture and oil content in soybeans.

Summary: The study investigated the effects of different roasting times (0, 2, 4, 6, 8, 10, 12, and 14 min) on the water distribution and key aroma compounds in roasted chicken during electric roasting process. GC-MS analysis identified 36 volatile compounds, with 11 compounds confirmed as key aroma compounds. The relaxation time of T22 and T23 showed an initial increase followed by a decrease, while M22 and M23 exhibited decreasing and increasing trends, respectively, as roasting time increased. The water fluidity decreased during roasting, with water of high freedom migrating to water of low freedom. Additionally, L*, a*, b*, M23, and all amino acids were positively correlated with all key aroma compounds, while T22, M22, and moisture content were negatively correlated.

Summary: This study investigated the mechanism of membrane damage by protocatechualdehyde (PCA) against Micrococcus luteus and found that PCA can effectively inhibit the growth of M. luteus by damaging the bacterial cell membrane. It also assessed the positive effects of PCA on the sensory and physicochemical properties of pork, such as preventing spoilage and improving color and texture.

Summary: In this study, sensors based on SnO2-TiO2 and SnO2-MoO3 composites were synthesized and characterized for the identification of adulteration or counterfeiting of Peruvian Pisco. The most sensitive sensors showed an enhanced response to alcoholic samples with higher ethanol content, while the response intensity decreased with increased methanol content. Differences in the composition of methanol and ethanol in different Pisco varieties correlated with the sensors' ability to differentiate them. SnO2-TiO2-1/2 composites exhibited greater reproducibility over time compared to other composites. Principal component analysis (PCA) results showed that composite sensors could effectively differentiate Pisco samples according to their varieties.
