"Consuming tourists: food tourism consumer behaviour" by Richard Mitchell and C. Michael Hall Page no. 60-80

This book chapter talks about exactly what you are searching for. You can try that and the book name is "Food Tourism Around The World"

Hi, 

for me interesting issue are food and wine festivals as well as culinary tourism 

regarded as a separate kind of tourism. 

Very good book about the food and wine festivals by C.M. Hall and L. Sharples:

and about culinary tourism book by L.M. Long:

I've attached the abstract from our forthcoming paper.  I have two gastro-tourism papers posted on this site which also should help.   We find that satisfaction is strongly related to the gastro-tourism brand promise.

ABSTRACT

This paper proposes that key factors exist for a geographic area to be recognized as a gastronomic destination with the potential to impact economic growth. Although exceptions exist based on certain intense singular food-related festivals or one-time gastro-experiences, this work suggests that a specific set of criteria is essential for sustaining a gastro-tourism enterprise that drives local economic growth. Secondary research has supported the premise that successful gastro-destinations include six or more authentic sites that link food to local culture and that operate within an infrastructure that mandates basic health, safety, transportation and communication practices. Furthermore, the six sites loosely connect and effectively market a co-branded promise. Preliminary research also exposes that recent emerging successful gastro-tourism destinations are additionally supported by one or more of the following: 1) local, regional &/or national government; 2) relevant civic or professional groups; and 3) local community members. This paper presents and discusses a Gastronomic Tourism Brand Promise Model that depicts these critical factors.
