Customisable, precise and flexible, microbiology is the most advanced and reliable technological device for tracking the freshness of food products. Using microbiology, CRYOLOG introduces the concept of Dynamic Use-By Date : a use-by date that adapts itself according to the real state of the product, rather than on the basis of pre-supposed preservation conditions.

Product Use-By Dates are determined by agri-food industrials. The Use-By Date corresponds to the period of time by the end of which the micro-organisms naturally present in the product reach a quantity that is critical for the product's sanitary or organoleptic quality (taste, texture, flavour…).

With the Dynamic Use-By Date, CRYOLOG offers a revolutionary concept: a use-by date that adapts itself according to the real conditions of the product's preservation :

• the product has been well preserved; the label changes colour on the use-by date defined by the industrial and printed on the packaging;
• the product has been subject to ruptures in the cold chain; the label changes colour before the Use-By Date; the longer and more extreme the ruptures in the cold chain, the sooner it will change colour.
