Abstract:The aim of this study was to investigate the influence of microwave drying on the protein quality of japonica sorghum following an intermittent drying test. Using label-free technology and liquid chromatography-tandem mass spectrometry for proteomic analysis, the effects of microwave drying on sorghum differential protein expression, functional classification, and metabolic pathways were analyzed at the molecular level. After sorghum was dried using a microwave, 85 differential proteins were identified. Among … Show more
“…The maritime pine (Pinus pinaster) and eucalyptus (Eucalyptus globulus) are two Portuguese wood species widely used for furniture, fences, and structural purposes. Analyzing small cores of wood treated in the MW, observed that eucalyptus heartwood takes longer to dry compared to pine heartwood, and the absorption of water after using MW obtained better impregnability than the control heartwood, being a viable possibility in the wood industry to work the raw material [15][16][17][18]. This example, and others related to the humidity of woods, shows all the versatile proposes the MW drying could have.…”
The use of electromagnetic energy for drying seeds has been shown to be a promising alternative. However, studies show that the technique still lacks careful evaluation due to the sensitivity of soybean seeds to damage caused using microwaves. Studies have shown that the use of microwaves during drying can be safe in seeds of soybeans, corn, and beans, among others. These studies recognize that drying using microwaves has a great potential for savings in the drying process, as it considerably reduces the drying time. This work aimed to evaluate the immediate damage caused in soybean seeds subjected to drying at temperatures of 40, 50, and 60 °C, with power of 0, 0.5, and 1 W/g at a frequency of 2.45 GHz. The results of the vigor and germination tests showed that the action of microwaves on seeds was not only safe and more efficient but also brought about increases in seed germination and vigor. However, the process must be judicious and obey precise indices of power and temperature to not cause damage to the seeds.

“…Therefore, it is necessary to study the mechanism of crack formation in corn kernels based on their temperature and water content. At present, the research on microwave drying mainly focuses on obtaining the best process parameters for drying different materials, as well as studying the germination rate, ketone content, protein content, amylose content, and other characteristic parameters of materials after drying (Çelen, 2019; Chahbani et al, 2018; Lv et al, 2018; Zhang et al, 2022). De Faria et al (2020), and Song et al (2013) studied the power, time, temperature, and moisture content during the microwave drying process of corn, which played a certain role in the study of corn microwave drying technology but ignored the influence of temperature and moisture content on drying cracks.…”
Background and ObjectivesDuring microwave drying process of corn, temperature and moisture content are the main reasons for crack formation, which reduces the drying quality. Therefore, it is necessary to study the effects of temperature and moisture content on crack generation.FindingsUnder the set drying conditions, as the temperature increases, cracks gradually increase, deformation gradually increases, and the crack index increases exponentially. As the moisture content decreases, deformation first increases and then decreases, single cracks first increase and then decrease and then increase, double cracks gradually decrease, multiple cracks continue to increase, and the crack index increases linearly. The deformation reaches its maximum value at a moisture content of 31%.ConclusionsThe results indicate that the generation of cracks is mainly influenced by water content. The maximum errors between the simulated and experimental values of temperature and moisture content are 4.73% and 7.76%, respectively, indicating that the model can be used to study the distribution patterns of temperature, moisture content, and deformation during corn drying.Significance and NoveltyThis study established a mathematical model for electromagnetic, mass, energy, and deformation of corn, coupled the model for the solution, and conducted experimental verification. The relationship between the generation of cracks during microwave drying of corn kernels and temperature and moisture content was revealed.
