This is the case of complex mixtures, such as certain cooked dishes, which are composed of a plurality of ingredients that must be able to be packaged, then prepare at the time of tasting, remaining the most faithful to the taste and taste. texture of the original recipe.
- the rheology of food is a paramount consideration that must be taken into consideration.
- This rheology which is particularly conditioned by the very nature of each ingredient, is sensitive to temperature, which makes it difficult to dispense prepared meals prepared from a mixture of several ingredients.
- the potato aligot is a dish mainly prepared from potato, tome (cheese), water and possibly cream and / or milk. If the preservation of such an aligot is known from the application FR 2 537 403 which describes a packaging in the form of frozen granules, the automated preparation of a dish that faithfully restores the taste properties, or even organoleptic properties of the original recipe is a difficult task.
