The influence of the non-linear diffusion on the mass transfer of a packaging contaminant into foodstuffs

Blog Article

The unsteady mass transfer of the packaging constituents to a food has been analysed.The diffusion coefficient inside the packaging was considered concentration - iPhone 7+/8+ variable while the food was considered concentration spatially gradientless.A well-known technique (Kirchhoff transformation) was used to solve the non-linear mass balance equation.The influence of the non-linear diffusion on the mass transfer mechanism and rate was analysed for different values MENS HOODIES of the partition coefficient and dilution coefficient.
