| Outline of Final Research Achievements |
To understand the factors behind variations in salt concentration during the cooking and production control of meals that make up the menus of food services, an experiment was conducted in which 50 dishes were cooked at different facilities.
The factors behind variations in the salt concentration of soup were the evaporation rate during heating and keeping warm, the volume of water adhering to food during washing, and the volume of water exuded from food. The evaporation rate in particular was influenced by the time during which the pot lid was opened or closed and the humidity of the kitchen and was related to the saltiness of the meal. These results constitute basic data for the quality control of soup prepared for food services. The same trends were seen for main and side dishes.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では給食を調理・提供する時に、料理の食塩濃度に影響する要因を具体的に明示し、給食の本来の目的である健康な食生活のモデルの食事として体験することを可能とするための品質管理に資する基礎的で有用な資料を構築した。これまで、給食の食塩濃度は計画量と提供量で変動することが把握されているが、その要因である調理条件や調理室内の環境などが影響する報告はなされていない。
本研究の知見により給食の食塩濃度の品質管理が向上し、適切な塩味で提供され、日常で健康な食生活の味付けを学ぶ機会が増すと、食塩摂取量の低減化に貢献でき、健康生活につながり、社会的な意義がある。
