“…products (Zeng, Han, & Zi, 2010). Hydrogen radicals in oleic acid treated with PEF were found to act as initiators in free-radical reactions (Zhao et al, 2011). These results were in close agreement with our findings that PEF lowered peroxide value and acidity number compare to the control samples.…”

“…PEF treatment of peanuts did not significantly change oil composition, acid number, peroxide value and carbonyl groups after a storage at 40°C for 100 days, and restrained lipid oxidation rate, thus extending shelf‐life of peanut oil‐rich products (Zeng, Han, & Zi, 2010). Hydrogen radicals in oleic acid treated with PEF were found to act as initiators in free‐radical reactions (Zhao et al, 2011).

Seed processing technologies are essential for seed safety and functionality through protection of physicochemical quality, pathogen inactivation, aflatoxin detoxification and alleviation of mutagenicity. Design of a pilot‐scale unit of pulsed electric fields (PEF) to treat sesame seeds with respect to quality parameters, Aspergillus parasiticus inactivation and aflatoxin reduction as well as alleviation of aflatoxin mutagenicity were prompted in this study. PEF energy ranged from 0.97 to 17.28 J achieved maximum reductions of peroxide value and acidity number of 67.4 and 85.7%, respectively, and did not change color L*, a*, b* and hue values. A 60% reduction of A. parasiticus counts occurred at the maximum PEF energy. Aflatoxins G1, G2, B1, and B2 contents decreased by 94.7, 92.7, 86.9, and 98.7%, respectively. Except for the samples treated by 2.16 J with 100 μg/plate and by 6.80 J with 10 μg/plate, PEF treatment provided elimination of aflatoxin mutagenity. It is concluded that PEF treatment can be used to treat sesame seeds with preservation of physicochemical properties, inactivation of A. parasiticus and decomposition of aflatoxins with reduced mutagenicity.

“…These conclusions were in accordance with the result of computational modelling of β‐CD–L‐Phe inclusion complex by AutoDock tool software. In addition, some previous studies reported that the PEF treatment can generate some free reactive radicals, such as hydrogen radicals, and hydrogen peroxide which could further generate hydroxyl or super oxygen free radicals (Zhang et al ., ; Zhao et al ., ), which free radicals and hydrogen peroxide could enter into β‐CD changing the microenvironment and thus more easily interact with the guest molecular bonds. Some previous studies confirmed that the PEF could influence the chemical and physical properties of macromolecular (β‐CD) (Han et al ., , ; Luo et al ., ).…”
In this work, the effect of pulsed electric fields (PEF) treatment on the interactions between amino acids (using L-Phenylalanine: L-Phe) and sugar (using b-Cyclodextrin: b-CD) complex was analysed by fluorescence spectroscopy, Raman spectroscopy and simultaneous thermal analyzer. Moreover, the molecular dynamics of b-CD-L-Phe inclusion complex treated by PEF was calculated by molecular modelling. The results indicated that b-CD-L-Phe complexes are formed by a molar ratio of 1:1, and the stability constant of such complexes increased from 147 to 614 M À1 by PEF treatment. Thermal characterisations of b-CD-L-Phe complexes indicated that the PEF treatment could increase the yield of complexes. The PEF treatment resulted in an increase in the reaction enthalpy of b-CD-L-Phe inclusion complexes by DSC curve. These results show that PEF treatment has the potential to promote the chemical processing, especially the small organic molecules participate in inclusion or cross-linking reaction.
“…Oleic acid is the main component of lipids, and aldehydes, ketones, alcohols, acids, and furans resulting from its oxidative decomposition is the major substances of food flavor ( Xie et al, 2022 , Bao et al, 2022 ). The oxidation process of oleic acid is considered as a typical free radical oxidation reaction with three steps: initiation, propagation, and termination ( Zhao, Yang, Shi, Pan, Zhang, Zhang, et al, 2011 ).…”

“…The decomposition of hydroperoxides is an important propagation link in the radical chain ( Turovskyj et al, 2007 , Endo et al, 2022 ). The final radicals undergo bimolecular reactions to form triacylglycerol polymers, which leading to the termination of the radical chain reaction ( Zhao, Yang, Shi, Pan, Zhang, Zhang, et al, 2011 ).
