The device for detecting, assessing and signaling thawing of deep frozen foodstuff includes a stratified disc (1), which can be applied to the product to be checked, and formed by a first support (3), a second support (7) and impermeable transparent films (8,9). A pattern (4), made on the first support (3) and extending up to a central display zone (6), is obtained by application of water expansion facilitating substances. Coloring water-soluble substances, which assume a well seen color when in contact with liquid water, are also applied to the display zone (6). The second support (7) has printed thereon information about the disc (1) use, and allows to see the display zone (6). The transparent and impermeable films, respectively upper (8) and lower (9), are fastened to the upper surface (3b) and to the lower surface (3a) of this first support (3).

1. Device for detecting, assessing and signaling thawing of deep frozen foodstuff, fit to be applied to an area of the product to be checked where liquid water is released during thawing, said device including:a first support (3), made of laminar, water permeable material; impermeable transparent films, upper (8) and lower (9) respectively, whose shape is identical to said first support (3), said upper and lower transparent films being respectively fastened to an upper surface (3b) and to a lower surface (3a) of said first support (3), so as to allow water to expand only from an outer edge zone (5); said device being characterized in that said first support (3) comprises a display zone (6), made of material such that said display zone (6) becomes at least partially transparent when reached by water, and a pattern (4), situated in said lower surface (3a), extending from said outer edge zone (5) to said display zone (6), formed by substances for facilitating water expansion through said pattern (4), said first support (3) also comprising coloring water-soluble substances applied to said lower surface (3a) in the display zone (6).
