Kinetic modelling of aflatoxins B1 conversion and validation in corn, rice, and peanut during thermal treatments

“…The content of free beeswax was determined by a DSC analysis. 22 Specifically, the film (about 5.0 mg) was weighted in a crucible and transferred to a preheated calorimeter (Diamond DSC, Perkin-Elmer, Shelton, CT) in a nitrogen bath of 40 mL/min. The sealed crucible was heated from 30 to 90 °C at a rate of 10 °C/min.…”

Soybean-protein isolate (SPI) has excellent film-forming capacity. However, the water vapor permeability of SPI film is high, which will cause the moisture lose of packaged products. The effect of high-pressure homogenization (HPH) on the water vapor permeability of SPI-beeswax films was evaluated. The HPH was effective at lowering the water vapor permeability of SPI-beeswax films to about 50% of the control. The HPH reduced the particle size of films and made their matrix more compact. The HPH improved the hydrophobicity of SPI-beeswax films. For the first time, we proved that the HPH improved the bound-beeswax content in SPI-beeswax films. The bound beeswax was effective at lowering the water vapor permeability of films rather than the free beeswax in the film matrix. In summary, the HPH lowered water vapor permeability of SPI-beeswax films by reducing their particle size and raising their hydrophobicity and bound-beeswax content.

“…The chemical reaction rate can be obtained using detailed or global/ reduced reaction mechanisms. However, due to the complexity of the aflatoxin degradation process, a detailed mechanism is still unavailable, and the researchers mainly utilise the one-step global reaction (Zhang et al, 2011;Agriopoulou et al, 2016).…”

“…where in the above equation, A, B, C and D are the concentration of aflatoxin, decontaminator component and the products, respectively. Based on the order of reaction, which determines the number of molecules participating in a reaction, the rate of aflatoxin degradation can be determined as (Zhang et al, 2011) follows:…”

Aflatoxins as the remarkable food safety issues are toxic compounds produced by some of the fungus among variety of food and feed products, while their decontamination has been investigated through some proposed kinetics based on the various conversion factors. Among them, in terms of the chemicalbased decontamination techniques, the zero-, first-and second-order reaction mechanisms are utilised conventionally alone or in combination with the Arrhenius model. However, the equilibrium adsorption, statistical inactivation models and the first-order reaction kinetics are the most common mathematical description of the physical based decontamination techniques. Finally, for biological based decontamination techniques, as several interconnected factors are involved, the response surface analysis (RSM) and the central composite design (CCD) methods are highly used. In this regard, the present review was aimed to provide an overview regarding the modelling approaches in aflatoxins decontamination based on the kinetics and thermodynamics aspects of the processes.
