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 preservation conditions of the product, rather than according to pre-supposed preservation conditions.

Product Use-By Dates are determined by agri-food industrials. The use-by date corresponds to the duration after which micro-organisms naturally present in the product reach a critical quantity for the product's sanitary quality 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 is 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.
