Patent

CA 2477110

The invention relates to a method of producing a frozen potato chip comprising the steps of peeling a potato, cutting the potato into strips, blanching the strips for a time equal to 60-95 % of the time to disintegration, drying the strips by 10-20 % by weight reduction in moisture content, frying the strips at 130-160 ~C for 20-30 seconds, and freezing the strips. The method has the combined effect of shrinking the surface layer of potato cells, so that a somewhat leathery 'skin' is developed. As a consequence the surface layer is less likely to absorb fat during the frying stage. Furthermore, because blanching is carried out to the optimum, the frying stage can be substantially shortened, and thus the opportunity for fat absorption is also reduced whilst allowing a caterer to better satisfy demand for freshly fried chips rather than frying in advance in anticipation of demand.

L'invention se rapporte à un procédé de production de frites congelées. Ce procédé consiste à : peler une pomme de terre, couper la pomme de terre en tronçons, blanchir les tronçons pendant un temps équivalent à 60-95 % du temps de désintégration, sécher les tronçons de façon à diminuer le contenu d'humidité de 10 % à 20 % en poids, faire frire les tronçons entre 130· et 160· de 20 à 30 secondes, et congeler les tronçons. Le procédé produit en outre un effet de rétrécissement de la couche de surface des cellules de pommes de terres, de façon à créer une sorte de <= peau tannée >=qui rend la couche de surface moins susceptible d'absorber la graisse lors de l'étape de friture. De plus, étant donné que le blanchiment est optimum, l'étape de friture peut être sensiblement raccourcie, ce qui réduit la possibilité d'absorption de graisse tout en permettant à un traiteur de mieux satisfaire la demande de frites cuites à la minute plutôt que de les cuire à l'avance par anticipation à la demande.
