AbstractsA multi-field coupled IR-HAD heat and mass transfer model was established to reveal the infrared hot air drying (IR-HAD) mechanism for shrinkage deformation of yam slices,and effects different temperatures on quality slices (color difference, rehydration ratio, polysaccharides,and allantoin content) were analyzed verified by experiments.The results show that simulated values considering (R2MR = 0.9841, R2temperature 0.9758) are in better agreement with experimental than without 0.8273, 0.8756).The moisture distribution inside slice showed a trend from outside, as external temperature rose, surface began evaporate, forming gradient. As accumulated, internal diffused outward,and gradients reduced.The humidity gradient chips rose increased, facilitating increasing rate migration.The highest overall evaluation obtained at 60°C color difference 7.49, ratio 2.65 kg/kg, polysaccharide content 24.17 mg/g, an 2.66 μg/g.

The use of innumerable chemical compounds in food production to enhance agricultural quality and yield has raised significant global concerns regarding safety. To address these concerns, miniaturized solid sample preparation techniques have emerged as an appealing strategy for analyzing residues complex samples, notably those found matrices. efficacy extraction procedures hinges largely on the choice sorbent phase. Molecularly imprinted polymers (MIPs) been introduced highly selective versatile phases a wide range techniques. Their remarkable selectivity is attributed creation distinct cavities during synthesis process, which subsequently accommodate target analyte when applied. This unique characteristic empowers MIP exhibit exceptional specificity toward desired analyte. MIPs methods shown great potential increase analytical performance residue evaluation Therefore, here we present comprehensive overview current landscape employing assessment samples. Moreover, this review primarily recent reports concerning application solid-phase microextraction (SPME), in-tube SPME, by packed (MEPS), disposable pipette (DPX), tip (SPE-PT) stir bar sorptive (SBSE). Lastly, will bring some future topics analysis order new avenues enhancing products' safety assessment.

Using hot air drying (HAD) and combined infrared (IR-HAD) test devices, the kinetics, unit energy consumption, color difference values, rehydration rate, microstructure, changes in polysaccharide allantoin contents of yam slices were examined at various temperatures (50 °C, 55 60 65 70 °C). The findings demonstrated that each aforementioned parameters was significantly impacted by temperature. IR-HAD dries quicker takes less time to dry than HAD. Deff is higher HAD same temperature increases with increase activation required for (26.35 kJ/mol) lower (32.53 kJ/mol). uses more per a factor greater 1.3. Yam treated had microscopic porosity, better rehydration, levels HAD-treated slices. °C greatest comprehensive rating after thorough analysis dried using coefficient variation method.

In this paper, the effects on drying time (Y1), color difference (Y2), unit energy consumption (Y3), polysaccharide content (Y4), rehydration ratio (Y5), and allantoin (Y6) of yam slices were investigated under different temperatures (50–70 °C), slice thicknesses (2–10 mm), radiation distances (80–160 mm). The optimal conditions determined by applying BP neural network wolf algorithm (GWO) model based response surface methodology (RMS). All above indices significantly affected (p < 0.05). rate effective water diffusion coefficient accelerated with increasing temperature decreasing thickness distance. selection lower helped reduce difference. increased then decreased temperature, thickness, distance, it was highest at 60 °C, 6 mm, 120 mm. At distance favored retention content. Under given constraints (minimization time, consumption, difference, maximization ratio, content, content), BP-GWO found to have higher coefficients determination (R2 = 0.9919 0.9983) RMSEs (reduced 61.34% 80.03%) than RMS. Multi-objective optimization carried out obtain conditions, as follows: 63.57 4.27 91.39 corresponding indices, Y1 133.71 min, Y2 7.26, Y3 8.54 kJ·h·kg−1, Y4 20.73 mg/g, Y5 2.84 kg/kg, Y6 3.69 μg/g. experimental verification prediction results, relative error between actual predicted values less 5%, proving model’s reliability for other materials in technology process research provide a reference.
