Abstract: A method of producing food products in the form of sheets includes preparing the pastry and, optionally, leaving the pastry to stand; distributing the pastry to cooking stations, depositing the pastry such as to form sheets and cooking same on one face thereof; recovering the sheets; and stacking the sheets before cooling and packing same. A treatment step, is performed when the sheets are removed from the cooking station but before stacking, consisting in treating at least one of the faces of the sheet in order to form a barrier thereon. The barrier prevents the moisture from migrating out of the sheet and rebalances moisture between the two faces. In this way, the stickiness of the sheet is reduced and the sheets can be stacked on top of one another without a separator. The invention can be used to produce sheet-type food products.
