Food identity and the passage of time

In this paper we provide a framework for studying the ways in which food endures the passage of time. Central to our inquiry is the following Duration Question: when is it that the predicate-schema “Is an X -Food,” where “X -Food” stands for a certain type of food (e.g., Champagne, yoghurt) ceases to apply to an entity? We show that the answer depends on two independent theoretical aspects: the underlying conception of food and the kinds of change that a specific food can undergo. We then argue that specific answers to the duration question should take the form of conceptual rethinking among different stakeholders (e.g., producers, consumers, institutions), where philosophers would feature among the experts guiding the negotiation.
