... Compared with the AD group, the increase in volatile compound content observed in the HAD group can be attributed to the high-temperature environment facilitating reactions between carbonyl compounds (reducing sugars) and amino compounds (amino acids and proteins), known as the Maillard reaction or carbonyl-amino reaction [19]. This In a plasma, certain particles and groups can undergo chemical reactions with surrounding substances under appropriate conditions, resulting in the formation of new material structures that alter the physical and chemical properties of the original substances. ...

... HHP processing is an environmentally sustainable, non-thermal technique that utilizes isostatic pressures between 100 and 1000 MPa, with or without added heat (Allai et al. 2023). HHP is a batch system that is extensively employed in the food industry to enhance the microbial safety, nutritional content, and functional properties of food products by utilizing water as a medium to transmit pressure (Wang, Ma, et al. 2024). The minimal impact on bioactive compounds is a significant advantage of HHP, which is a result of the low or moderate temperatures involved. ...

... On the other hand, long-chain fatty acid derivatives like palmitic acid and stearic acid augment the hydrophobicity of starch, potentially reducing its water solubility but enhancing its solubility in non-polar solvents. Long-chain fatty acid-modified starches often exhibit improved thermal stability and mechanical properties, making them advantageous for high-temperature processing and various applications [153][154][155]. ...

... In particular, the FRAP assay, which measures the ability of a sample to reduce ferric ions to ferrous ions, may show elevated antioxidant values due to the presence of bioactive peptides containing a high proportion of amino acids such as histidine, cysteine, and methionine, which facilitate iron reduction. These amino acids are known for their ability to interact with metal ions and exhibit reducing activity [35]. The potential predominance of such amino acids in the peptide mixture could enhance the observed antioxidant activity in the FRAP assay compared to other methods, which focus on different mechanisms such as scavenging free radicals or measuring overall oxygen radical absorbance capacity. ...

... Their method effectively solves the stability problem when there is simultaneous quantization of the control inputs and state measurements. Data quantization introduces quantization errors that affect the accuracy of the control system [32][33][34]. In high-speed train speed-tracking control, finding the optimal way to effectively deal with quantization errors in order to ensure the performance of the control system is an urgent matter. ...

... In reality, the interaction between them usually involves a combination of multiple types of forces. Zhang, Yang et al. (2024) found that coupling with maltose extended the otherwise compact structure of soybean isolate proteins, increased molecular flexibility, and led to increased exposure of hydrophobic residues and charged charges within them. Their aggregates could form a thicker interfacial layer at the oil-water interface, providing a better three-dimensional barrier and enhancing the spatial repulsion between oil droplets Nooshkam et al., 2023). ...

... Enzymatic hydrolysis enhances protein digestibility by breaking down high-molecularweight proteins into smaller peptides and amino acids, making them more accessible to digestive enzymes. A study demonstrated that limited hydrolysis using papain significantly reduced the molecular weight of a soy protein isolate and corn zein mixture while increasing the proportion of random coil structures [145]. These structural modifications facilitated protein breakdown, resulting in a remarkable improvement in in vitro digestibility. ...

... Studies have shown that piperine can enhance the bioavailability of certain drugs and exert regulatory effects on the nervous and immune systems [13]. In addition, the fruit of PN contains volatile oil components, such as terpenes and aromatic compounds, which primarily contribute to its characteristic aroma [14]. It has been shown that certain polyunsaturated fatty acids in PN, such as oleic acid and linoleic acid, offer significant cardiovascular health benefits [15]. ...
