The faculty of the food industry to adapt to different technical and e
conomic contexts rests less on an aptitude for radically reviewing exi
sting processes, products or knowledge than on a capacity for maintain
ing them so as to combine them. In this way it is able to meet the cha
llenge of new social functions or marketing strategies. This rational
control of its craft traditions is particularly marked in the European
food industry. It manifests itself less by ruptures than by the affir
mation of certain continuity that profoundly markets industrial strate
gies and R&D policies.
