Abstract

In this paper, we propose a method used to code recipe data based on a recipe's cooking process and the quantity of its nutrients. A recipe coding method has been proposed in a preceding study; however, it has two problems. The first problem is that the recipe data do not contain information about the cooking process. The second problem is that the recipe data do not consider how the cooking process change the quantity of nutrients in the recipe. Therefore, to resolve these issues in this study, we propose using a tree structure as the method for coding recipe data. The recipe data can include the cooking process using the tree structure. In addition, the recipe data can reflect changes in the quantity of nutrients caused by the cooking process. In this study, we calculate the quantity of nutrients by using the conventional technique of previous studies and our proposed technique that uses a tree structure. As a result, the recipe data coded with the tree structure can calculate the quantity of nutrients for a recipe and achieve results that are closer to the values of the original recipe than those calculated using the conventional method of coding recipe data.
