Simple modelling of time-temperature profiles in food during baking

Applied Food Research, 2023
Time-temperature profiles (TTP) in food during baking and other heat treatments are essential to understand and characterise a series of changes related to product quality, and for design, control and optimisation of the process.

Moving boundary problems with Ermakov symmetry reduction: nonlinear superposition principle and reciprocal transformation applications [PDF]

Open Communications in Nonlinear Mathematical Physics
Moving boundary problems of Stefan-type for a novel third order nonlinear evolution equation with temporal modulation are here shown to be amenable to exact Airy-type solution via a classical Ermakov equation with its admitted nonlinear superposition ...
