Application of Different Staining Methods in the Diagnosis of Pigment-Rich Melanoma.

To compare the application of different treatments in the diagnosis of melanoma with severe pigment interference, to solve the problem of pigment interference with immunohistochemical interpretation. The pigment-rich melanomas were first depigmented with potassium permanganate using a concentration gradient (0.1%, 0.5%, 1%) and a time gradient (1, 5, 10, 15, 30 min, 6 h), and the optimal concentration and time were found. Then, 12 cases of pigment-rich melanoma tissues were collected, and the tissues were stained with diaminobenzidine (DAB), alkaline phosphatase-fast red (AP red), multiplex immunofluorescence (MIF), and 3-amino-9-ethylcarbazole (AEC), and ferrous sulfate, comparing different methods, positive expression of HMB45, MelanA, S100, SOX10, ki67. First, the concentration of 0.5% potassium permanganate after 15 min treatment of the pigment significantly faded, and the intensity of antibody positivity was better than other concentrations and time. Second, after depigmentation treatment, the antibody positivity rate was 41.7%-66.7% for DAB, 66.7%-91.7% for AP red, 83.3%-100% for multiplex immunofluorescence, 25%-33.3% for AEC, and 33.3% for ferrous sulfate. AP red staining and mIF are more suitable for the diagnosis of melanoma with severe pigment interference, and AP red staining is more economical and practical.

Microwave‐assisted treatment for the improvement of rice flour properties and rice flour bread quality

SummaryModification of rice flour by microwave and its effect on bread making performance was evaluated. Rice flour having two different water content (20% and 30%) were exposed to different level of microwave power (600 W, 700 W and 800 W) with 8 min treatment time to assess its influence on amylose content, thermal properties, morphological structure, functional and crystalline structural that affect bread quality. Microwave‐treated rice flour at 600 W showed notable increment in amylose content of 1.03 folds (for both 20% and 30% water content) as compared to untreated rice flour. The microwave treatment destroyed the amorphous region of the rice flour starch, whereas starch crystal structure was slightly increased after treatment. Rice flour maintained its thermal stability even after exposure to high radiation of microwave. The treated rice flour exhibited starch granules with more voids on its surface, indicating the exudation of amylose at higher temperature. The major effect of microwave treatment was observed on the bread for rice flour treated at 800 W with higher specific volume, increase in gas cells pores, softer crumb, low hardness and delayed staling as compared to untreated rice flour. The microwave‐assisted treatment shows a significant potential in improving the rice flour quality led to increase the quality of bread.

Photocatalytic Degradation of Levofloxacin and Inactivation of Enterococci Levofloxacin-Resistant Bacteria Using Pure Rare-Earth Oxides

In this study, La2O3 and CeO2 nanopowders were prepared using a simple and cost-effective precipitation method. Wide-angle X-ray diffraction (WAXD), UV-Visible reflectance diffuses (UV-Vis DRS), Raman spectroscopy, and specific surface area were used to characterize the photocatalysts, evidencing that the used preparation method was effective in the generation of crystalline CeO2 and La2O3. In particular, WAXD results showed that the average crystallite size of the achieved La2O3 and CeO2 samples were about 22 nm and 28 nm, respectively. The photocatalytic performances of the prepared catalysts were investigated in the degradation of levofloxacin (LEV) and the inactivation of a waterborne pathogen levofloxacin resistant (Enterococcus faecalis ATCC 29212) by using a photoreactor equipped with a solar simulator (SS). After 120 min, the CeO2 and La2O3 photocatalytic treatments allowed us to achieve between 75% and 83% of levofloxacin removal, respectively. A complete removal of 106 CFU/mL Enterococcus faecalis ATCC 29212 was achieved after 5 and 60 min of La2O3 and CeO2 photocatalytic processes, respectively.

Bacterial Inactivation Studies in Shrimp Pond Water by Using Different Disinfectant Agents.

Aquaculture water plays an important role in the dissemination of antibiotic-resistant bacteria during harvest of shrimps. Mitigation of bacteria through discharge is essential to prevent dissemination downstream. Chemical disinfection of culture water is feasible compared to other methods of bacterial inactivation. To study the effect of different disinfectant agent's viz., chlorine, Fenton's reagent, and hydrogen peroxide (H2O2) on inactivation of bacteria from shrimp pond water. The water samples were subjected to treatment with various concentrations of chlorine (0.0, 1.0, 2.5, 5.0, and 10.0 mg/L), Fenton's reagent (1:10 mM ratio of Fe2+:H2O2; 2:20, 3:30, 4:40, 5:50) and H2O2 (20, 30, 40, and 50 mM) for different time durations (5, 15, 30, and 60 min). The results indicated that all the disinfecting agents inactivated both the total heterotrophic bacteria and tetracycline-resistant bacteria with increased concentrations and time. At the end of 60 min treatment with chlorination (2.5 mg Cl2/L), Fenton's reagent (2 mM Fe2+ + 20 mM H2O2), and H2O2 (50 mM H2O2), the total heterotrophic bacterial count in the water samples gradually decreased by 2.35, 2.65, and 1.38 Log10 CFU/mL, and tetracycline-resistant bacterial count reduced by 1.57, 1.66, and 1.43 Log10 CFU/mL respectively, from initial bacterial load. The study revealed that disinfection agents can be successfully employed in the inactivation of antibiotic-resistant bacteria discharged through aquaculture water. Among three disinfection agents, Fenton's reagent has been found effective in inhibiting both heterotrophic bacteria and tetracycline-resistant bacteria from water samples. Bacterial inactivation studies were carried with chlorination, Fenton's reagent, and hydrogen peroxide. The highest reduction in Heterotrophic Plate Count (HPC) (2.65 Log) and tetracycline-resistant count (1.66 Log) was noticed in the water samples treated with Fenton's reagent. The use of disinfection agents effectively mitigates antibiotic-resistant bacteria from aquaculture wastewater.

Minocycline alleviates lipopolysaccharide-induced cardiotoxicity by suppressing the NLRP3/Caspase-1 signaling pathway.

Minocycline (Min), as an antibiotic, possesses various beneficial properties such as anti-inflammatory, antioxidant, and anti-apoptotic effects. Despite these known qualities, the precise cardioprotective effect and mechanism of Min in protecting against sepsis-induced cardiotoxicity (SIC) remain unspecified. To address this, our study sought to assess the protective effects of Min on the heart. Lipopolysaccharide (LPS) was utilized to establish a cardiotoxicity model both in vivo and in vitro. Min was pretreated in the models. In the in vivo setting, evaluation of heart tissue histopathological injury was performed using hematoxylin and eosin (H&E) staining and TUNEL. Immunohistochemistry (IHC) was employed to evaluate the expression levels of NLRP3 and Caspase-1 in the heart tissue of mice. During in vitro experiments, the viability of H9c2 cells was gauged utilizing the CCK8 assay kit. Intracellular ROS levels in H9c2 cells were quantified using a ROS assay kit. Both in vitro and in vivo settings were subjected to measurement of oxidative stress indexes, encompassing glutathione (GSH), malondialdehyde (MDA), and superoxide dismutase (SOD) levels. Additionglly, myocardial injury markers like lactate dehydrogenase (LDH) and creatine kinase MB (CK-MB) activity were quantified using appropriate assay kits. Western blotting (WB) analysis was conducted to detect the expression levels of NOD-like receptor protein-3 (NLRP3), caspase-1, IL-18, and IL-1β, alongside apoptosis-related proteins such as Bcl-2 and Bax, and antioxidant proteins including superoxide dismutase-1 (SOD-1) and antioxidant proteins including superoxide dismutase-1 (SOD-2), both in H9c2 cells and mouse heart tissues. In vivo, Min was effective in reducing LPS-induced inflammation in cardiac tissue, preventing cell damage and apoptosis in cardiomyocytes. The levels of LDH and CK-MB were significantly reduced with Min treatment. In vitro studies showed that Min improved the viability of H9C2 cells, reduced apoptosis, and decreased ROS levels in these cells. Further analysis indicated that Min decreased the protein levels of NLRP3, Caspase-1, IL-18, and IL-1β, while increasing the levels of SOD-1 and SOD-2 both in vivo and in vitro. Min alleviates LPS-induced SIC by suppressing the NLRP3/Caspase-1 signalling pathway in vivo and in vitro.

Modifying physicochemical properties, rheology, and creaming stability of milk fat globule and membrane through ultrasound treatment

The healthy benefits of milk fat globules and membrane (MFGs/MFGM) ingredients are increasingly recognized in the dairy industry. In this research, we examined the effects of ultrasonic treatment on the physicochemical and rheological properties, as well as the emulsions stability of MFGs/MFGM derived from bovine raw milk. Fresh milk was subjected to sonication at frequencies of 20kHz and 40kHz, either individually or simultaneously, for durations of 5min or 15min, using work/rest cycles of 5s on and 3s off. Bovine milk, without any treatment, served as the control. Regardless of the intensity difference, ultrasonic treatment for 5min resulted in more pronounced changes in the regions of Amide Ⅱ (1600-1500cm-1), Amide Ⅲ (1500-1200cm-1), and fingerprint region (1200-1900cm-1) compared to both the 15min treatments and control MFGs/MFGM. Principal component analysis (PCA) conducted on the entire spectra, as well as in the regions of Amide Ⅰ, Amide Ⅱ, and the fingerprint spectra, clustered the 5min treatment distinctly from the control and MFGs/MFGM ultrasonically treated for 15min. MFGs/MFGM samples following 20kHz and 40kHz synchronous treatment for 15min exhibited lower absorbance bands at 1727-1726cm-1, whereas a higher content at 1740cm-1 was observed compared to control MFGs/MFGM. Additionally, a more significant reduction in the intramolecular β-sheet content in 20+40kHz/ 15min treatment was observed. According to the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) patterns, a diminished intensity of Periodic Acid Schiff 6/7 (PAS 6/7) bands was observed across all the MFGs/MFGM. Ultrasonic treatment retained more caseins while reducing the β -LG levels compared to the controls, enhancing the stability of MFGs/MFGM, except in MFGs/ MFGM subjected to 20 and 40kHz simultaneously treated for 15min. The irregular sphericity of fat globules was noted particularly in MFGs/MFGM treated at 20kHz independently or in combination with 40kHz for 15min. According to the confocal laser scanning microscopy (CLSM), ultrasonic treatment facilitated the binding of caseins or whey proteins to the MFGs surface and induced flocculation of membrane proteins. Hierarchical cluster analysis (HCA) heat map further underscored the impact of ultrasonic treatments on the structural and compositional changes, as well as rheology and emulsions stability, of MFGs/MFGM.

Research and Analysis on Enhancement of Surface Flashover Performance of Epoxy Resin Based on Dielectric Barrier Discharge Plasma Fluorination Modification.

To conquer the challenges of charge accumulation and surface flashover in epoxy resin under direct current (DC) electric fields, numerous efforts have been made to research dielectric barrier discharge (DBD) plasma treatments using CF4/Ar as the medium gas, which has proven effective in improving surface flashover voltage. However, despite being an efficient plasma etching medium, SF6/Ar has remained largely unexplored. In this work, we constructed a DBD plasma device with an SF6/Ar gas medium and explored the influence of processing times and gas flow rates on the morphology and surface flashover voltage of epoxy resin. The surface morphology observed by SEM indicates that the degree of plasma etching intensifies with processing time and gas flow rate, and the quantitative characterization of AFM indicates a maximum roughness of 144 nm after 3 min of treatment. Flashover test results show that at 2 min of processing time, the surface flashover voltage reached a maximum of 19.02 kV/mm, which is 25.49% higher than that of the untreated sample and previously reported works. In addition to the effect of surface roughness, charge trap distribution shows that fluorinated groups help to deepen the trap energy levels and density. The optimal modification was achieved at a gas flow rate of 3.5 slm coupled with 2 min of processing time. Furthermore, density functional theory (DFT) calculations reveal that fluorination introduces additional electron traps (0.29 eV) and hole traps (0.38 eV), enhancing the capture of charge carriers and suppressing surface flashover.

Novel method for finishing nonwoven fabrics from domestic raw materials with flame retardant and antimicrobial properties

This study aims to obtain a non-woven material with flame retardant and biocidal properties, considering the use of salicylic acid, copper sulfate, and guanidine hydrochloride in a finishing composition, based on preliminary studies. The concentrations of copper sulfate, guanidine hydrochloride, and salicylic acid were varied, respectively, within 1–5 g/L, 5–15 g/L, and 3–7 g/L. The conditions of the finishing process involved the application of the aqueous solutions, by spraying on the surface of the material, followed by drying at 120 °C for 5 min and heat treatment at 180 °C on a thermal press. In the production of nonwovens, treatment with a flame retardant and biocidal composition can be combined with emulsification of a mixture of fibers, or carried out after the formation of the canvas with subsequent heat treatment and calendering. The untreated sample of non-woven material, when tested for flammability with an ignition time of 15 s, burns completely in 40 s. For the sample treated by the proposed method, the self-burning is reduced to zero (DIN 53906). To study the biocidal activity, a microbiological essay was conducted according to ASTM E2149. It was found that the tested sample exhibits fungicidal activity against the tested strains. In addition, tests conducted on the skin-irritating effects of nonwovens treated with the proposed method have shown its safety for human health.

Stereotactic centralized ablative radiation therapy: A novel methodology in treating bulky tumor and its technical realization.

159 Background: Bulky tumors pose significant challenges to traditional treatment modalities such as surgery, chemotherapy, and conventional radiotherapy. This study introduces a novel therapeutic approach named as Stereotactic-Core-Ablative-Radiation-Therapy (SCART), designed to deliver an ablative dose to a substantial core of the bulky tumor while quickly decreasing to a lower dose at the tumor periphery. Methods: A SCART-Treatment-Volume (STV) at the core of the GTV was predefined to administer an ablative radiation dose, aiming to induce DNA damage in cancer cells and potentially trigger biological cancer-killing effects. Utilizing Linac-based VMAT or Cyberknife techniques with 6MV photon beams, multiple radiation fields intersect and optimize at STV, generating an ablative dose at the STV. The dose rapidly diminishes to a safe level at the edge of GTV sparing the surrounding tissue. In the phase-1 trial, nineteen patients with 21 bulky tumors enrolled, receiving SCART at five dose levels (15GyX1, 15GyX2, 15GyX3, 18GyX3, 21GyX3, and 24GyX3), while maintaining the GTV's peripheral dose at 5Gy each fraction. Results: All patients completed treatment with average beam-on time of 8.9min and average treatment time of 18.5min. Mean follow-up time is 15.4 month. No grade-III or higher toxicity was observed. 7/19 patients still survive, with the overall survival of 40% at 30 months. Mean tumor volume shrinks by 60% between initial 301cc and post-SCART volumes of 118cc. Long-term follow-up revealed that 14/21 tumors achieved Partial Response, 2/21 Complete-Response, 3/21 Stable-Disease, and 1/21 Progressive-Disease, leading to an encouraging local control of 95%. Conclusions: SCART emerges as a safe and effective strategy for treating bulky malignant tumors, demonstrating excellent local control and overall survival. Multiple treatment courses were feasible. The results from phase-1 study suggest that SCART could revolutionize the treatment landscape for bulky tumors, offering a promising avenue for further exploration and application in clinical practice.

Biochemical Characterization and Application of Zearalenone Lactone Hydrolase Fused with a Multifunctional Short Peptide.

Zearalenone (ZEN) is an estrogenic mycotoxin causing reproductive toxicity in livestock. Currently, lactone hydrolases are used in the enzymatic degradation of ZEN. However, most lactone hydrolases suffer from low degradation efficiency and poor thermal stability. ZHD518, as a documented neutral enzyme for ZEN degradation, exhibits high enzymatic activity under neutral conditions. In this study, a multifunctional peptide S1v1-(AEAEAHAH)2 was fused to the N-terminus of ZHD518. Compared with the wild-type enzyme, the peptide fusion significantly enhanced protein expression by 1.28 times, enzyme activity by 9.27 times, thermal stability by 37.08 times after incubation at 45 °C for 10 min and enzyme stability during long-term storage. Moreover, ZEN concentrations in corn bran, corn germ meal, and corn gluten powder decreased from 5.29 ± 0.04, 5.31 ± 0.03, and 5.30 ± 0.01 μg/g to 0.48 ± 0.05, 0.48 ± 0.06, and 0.21 ± 0.04 μg/g, respectively, following a 60 min treatment with S1v1-GS-ZHD518, resulting in degradation rates of 90.98, 91.00, and 95.32%, respectively. In conclusion, the properties of S1v1-GS-ZHD518, such as its efficient degradability, high temperature resistance and storage resistance, offer the possibility of its application in food or feed.

Enhanced degradation of tetracycline by gas-liquid discharge plasma coupled with g-C3N4/TiO2

Plasma-catalysis is considered as one of the most promising technologies for antibiotic degradation in water. In the plasma-catalytic system, one of the factors affecting the degradation effect is the performance of the photocatalyst, which is usually restricted by the rapid recombination of electrons and holes as well as narrow light absorption range. In this research, a photocatalyst g-C3N4/TiO2 was prepared and coupled with gas-liquid discharge (GLD) to degrade tetracycline (TC). The performance was examined, and the degradation pathways and mechanisms were studied. Results show that a 90% degradation rate is achieved in the GLD with g-C3N4/TiO2 over a 10 min treatment. Increasing the pulse voltage is conducive to increasing the degradation rate, whereas the addition of excessive g-C3N4/TiO2 tends to precipitate agglomerates, resulting in a poor degradation efficiency. The redox properties of the g-C3N4/TiO2 surface promote the generation of oxidizing active species (H2O2, O3) in solution. Radical quenching experiments showed that ·OH, hole (h +), play important roles in the TC degradation by the discharge with g-C3N4/TiO2. Two potential degradation pathways were proposed based on the intermediates. The toxicity of tetracycline was reduced by treatment in the system. Furthermore, the g-C3N4/TiO2 composites exhibited excellent recoverability and stability.

Potential of cold plasma pretreatment for preserving biochemical attributes and ensuring the microbiological safety of saffron stigma.

Saffron, similar to numerous other agricultural commodities, is susceptible to microbial contamination during cultivation and postharvest handling. Cold plasma treatment has emerged as an effective method for microbial inactivation while preserving food quality. The aim of this research was to preserve the color integrity and minimize the presence of microorganisms in dried saffron stigma by implementing cold plasma pre-treatment. Process parameters were optimized using the response surface method (RSM), considering the type of atmosphere (argon and air), plasma exposure time (1, 5, and 10 min), and plasma power (40, 70, and 100 W) as independent variables. The objectives were to maximize crocin content and minimize the total microbial load. The analysis of the response surface revealed that the argon atmosphere had a more significant impact on reducing microbial contamination than air, and an increase in plasma exposure time led to a decrease in microbial load. The maximum reduction in microbial load, by 0.9 logarithmic cycles compared to the control, was achieved with a 10-min treatment at 40 W power. Extended plasma exposure durations led to a minor reduction in the color, taste, aroma, and antioxidant properties of saffron stigma. Specifically, the color, taste, and aroma decreased by 0.5%, 0.5%, and 0.08%, respectively, with longer plasma exposure times. The antioxidant activity decreased by 0.64% with prolonged exposure time. However, the plasma-treated samples did not show any signs of Escherichia coli, mold, or yeast. Furthermore, our findings demonstrated that the type of atmosphere significantly influenced the reduction of infection and maintenance of saffron stigma's color quality. Cold plasma pretreatment holds promise as a viable method for preserving the physicochemical attributes of saffron while effectively reducing microbial contamination.

A magnetic-guided nano-antibacterial platform for alternating magnetic field controlled vancomycin release in staphylococcus aureus biofilm eradication.

Bacterial resilience within biofilms, rendering them up to 1000 times more resistant to antibiotic drugs, poses a formidable challenge. This study introduces a targeted biofilm eradication strategy, termed "target-penetration-killing-eradication", implemented through magnetic micro-robotic technology. Specifically, we present the development of a magnetic-guided nano-antibacterial platform designed for alternating magnetic field (AMF) controlled vancomycin release in the eradication of Staphylococcus aureus biofilms. To address the issue of premature vancomycin release in physiological conditions, we employed a temperature-sensitive linking agent, 4,4'-azobis(4-cyano valeric acid), facilitating the conjugation of vancomycin onto Fe3O4/CS nanocomposites, resulting in the novel construct Fe3O4@CS-ACVA-VH. The release mechanism adheres to first-order kinetics and Fickian diffusion, with each 10-min AMF treatment releasing approximately 8.4 ± 1.1% of vancomycin. The potency of vancomycin in the release solution was similar to that of the original drug (MIC: 7.4 ± 3.5 vs. 5.6μg/mL). Fe3O4@CS-ACVA-VH exhibited sustained antibacterial efficacy, inhibiting bacterial growth for four consecutive days and preventing the formation of bacterial biofilms on its surface. Contact-inhibition bacterial activity of Fe3O4@CS-ACVA-VH against S. aureus was 0.046875mg/mL. Conceptually validating our approach, we emphasize Fe3O4@CS-ACVA-VH's exceptional ability to penetrate S. aureus biofilms under static magnetic field attraction. Furthermore, the nano-platform offers the unique advantage of on-demand vancomycin release through alternating magnetic field stimulation, effectively clearing a larger biofilm area. This multifunctional nano-platform demonstrates magnetic-guided biofilm penetration followed by controlled vancomycin release, presenting a promising strategy for enhanced biofilm eradication.

Comparison of the Bactericidal Effect of Ultrasonic and Heat Combined with Ultrasonic Treatments on Egg Liquids and Additional Analysis of Their Effect by NIR Spectral Analysis.

Eggs are a valuable source of nutrients, but they represent a food safety risk due to the presence of microbes. In this work, three types of egg liquids (albumen, yolk and whole egg) previously contaminated with E. coli were treated with ultrasound (US) and a combination of ultrasound and low (55 °C) temperature (US+H). The US treatment parameters were 20 and 40 kHz and 180 and 300 W power and a 30, 45 or 60 min treatment time. The ultrasonic treatment alone resulted in a reduction in the microbial count of less than 1 log CFU, while the US+H treatment resulted in a reduction in CFU counts to below detectable levels in all three egg liquids. Heat treatment and ultrasound treatment had a synergistic effect on E. coli reduction. For all measurements, except for the whole egg samples treated with US, the 20 kHz treated samples showed a significantly (>90% probability level) lower bactericidal effect than the 40 kHz treated samples. PCA and aquaphotometric analysis of NIR spectra showed significant differences between the heat-treated groups' (H and US+H) and the non-heat-treated groups' (US and control) NIR spectra. LDA results show that heat-treated groups are distinguishable from non-heat-treated groups (for albumen 91% and for egg yolk and whole egg 100%).

Quality changes in high hydrostatic pressure treated enriched tomato sauce.

Use of high hydrostatic pressure (HHP) with reduced processing times is gaining traction in the food industry as an alternative to conventional thermal treatment. In order to enhance functional benefits while minimizing processing losses, functionalized products are being developed with such novel techniques. In this study, changes in quality parameters for HHP treated enriched tomato sauce were evaluated, with the aim to assess its viability as an alternative to conventional thermal treatment methods. HHP treatments at 500 MPa, 30 °C/50 °C significantly increased the total phenolic and lycopene content of the sauce samples, achieving 6.7% and 7.5% improvements over conventionally treated samples. The antioxidant capacity of the HHP-treated samples was also found to match or be better than conventionally treated samples. Furthermore, a T2 relaxation time study revealed that pressure-temperature processing treatments were effective in maintaining the structural integrity of water molecules. Microbiological analyses revealed that 500 MPa/50 °C 5 min treatment can offer 8 logs reduction colony formation, matching the results of conventional thermal treatment. Combined pressure-temperature treatments improve results, reduce time consumption. 500 MPa/50 °C treatments provided retention of quality parameters and significant reduction in microbial activity. © 2024 The Author(s).

Effects of Different Pretreatments on the GABA Content of Germinated Brown Rice

Brown rice germination increases γ-aminobutyric acid (GABA) levels and enhances its antioxidant activity. In this study, Kaohsiung 145 brown rice was used as the raw material, and soaked in various solutions for 6 h before being processed with either high-pressure processing (HPP) or ultrasonic treatment to increase the GABA content. The GABA and antioxidant components of brown rice were analyzed after 42 h of germination and subsequent air-drying to obtain a moisture content of 14%. The results showed that non-germinated brown rice had GABA at 7.10 mg/100 g and treatment with various soaking solutions (0.1% CaCl2, 0.1% Glu, 0.2% CaCl2, and 0.2% Glu) increased GABA contents. Specifically, 0.1% CaCl2 and 0.1% Glu exhibited higher GABA content, at 42.51 and 44.64 mg/100 g. Furthermore, the GABA content increased synergistically when combined with HPP (100 MPa, 10 min) and ultrasonic (20 min) treatments after soaking. The results showed that the GABA contents in germinated rice were the greatest after ultrasonic treatment, followed by HPP treatment, and the least with only soaking treatment. The treatments with 0.1% CaCl2 and 0.2% Glu combined with ultrasonic processing for 20 min resulted in the highest GABA content at 102.38 and 110.88 mg/100 g, respectively. Finally, 0.1% CaCl2 with ultrasonic treatment for 20 min was chosen, as it demonstrated a considerable improvement in total polyphenols content and DPPH scavenging abilities, as seen by improved scores in subsequent taste evaluations.
