Texture prediction during deep frying: A mechanistic approach

► Texture for a French fry was predicted from first principles, using a diffusion-reaction framework. ► The framework consists of transport of moisture, oil and energy plus texture development (as a reaction) that depends on moisture and temperature. ► Overall texture is predicted from local texture through a process called homogenization. ► Study contrasts with total empirical prediction of texture, as is generally the case in literature. ► Framework developed is easily extended to processes other than frying.
