A method of freezing a product comprises the step of forming an indentation on the frozen food product. Such identification is capable of being irreversibly altered after the frozen food product is thawed so that it is an indication that the frozen food product has been thawed during storage.

L'invention a trait à un procédé de congélation d'un produit alimentaire, qui comprend l'étape consistant à former une échancrure sur ledit produit alimentaire congelé. Une telle échancrure a la particularité d'être modifiée de manière irréversible une fois que le produit alimentaire a été décongelé, si bien qu'elle indique que le produit alimentaire congelé a été décongelé lors de son stockage.
