Answer:
to inform the reader about the products and foods that a region offers
Step-by-step explanation:
Books that tell about travels are called travelogues. There are few reasons for writing such a book:
1) informing readers about landscape, place, customs, culture, region etc.
2) persuading readers to visit a specific location
3) entertaining readers with stories of travel and following adventures
This particular excerpt is purely informational; it provides some basic information on foods and products of a given region, without giving any details of the trip itself or trying to persuade readers to visit the place.
