In an acetic acid food system, the major characteristics of the heating process are heat transfer and mass transfer. During high-temperature heating, an acetic acid system contains a heat boundary layer (HBL). For the food system, AA and HMF formations are complex on the inside of the HBL. To assess the effects of chitosan addition on the inhibition of AA formation, a kinetic model in the food system was developed that combined the Langmuir adsorption mechanism, the coverage function, the relative efficiency of chitosan dispersion, and the step function to predict the entire heating time. The inhibition of AA formation in asparagine-glucose-chitosan solution is dependent on chitosan addition and chitosan dispersion on the inside of the HBL. For extending heating duration, AA forms with high loading of glucose and asparagine were significantly higher than those with low loading. The effect of the asparagine on the AA content is related to one reaction pathway in the AA formation. However, the effect of sugar reduction on the AA content is due to two reaction pathways. For heating circumstances, a process prediction with different glucose and asparagine loadings was developed. |
