A study to make a food and nutrient composition database for dietary surveys

从现有的饮食记录数据中，我们选择了油炸蔬菜，它代表了日本人每天摄入的含有多种食物的混合菜肴。在做了一个典型的食谱后，我们煮了食物，拍下了照片，称了它的体积。此外，我们还称量了烹饪前后的配料，并计算了两者之间的重量变化系数。利用这一基本数据，我们试图制作出每100毫升混合菜肴的营养成分表格。此外，我们考虑了一种猜测在个人计算机屏幕上显示的混合菜肴的可能体积的方法。

We chose, from the existent dietary record data, fried vegetables represented as mixed dishes containing multiple food items that the Japanese take in daily. After making a typical recipe, we cooked the food, took photos of it, and weighed its volume. Also, we weighed the ingredients before and after the cooking, and calculated the coefficient of the weight change in between. By using this basic datum, we tried to make a table of the nutrient composition per 100ml of the mixed dishes. Furthermore, we considered a method of guessing the possible volume of mixed dishes displayed on the screen of a personal computer.
