报告摘要：Grain hydration is a process occurring naturally in agriculture and food engineering. It plays a crucial role in seed storage and germination as well as in grain pretreatment process during cooking. Since grain tissue contains many strong hydrophilic substances such as cellulose, starch and protein, etc., when grains are soaked in water, water molecules penetrate into the inner part of grains and then combine with these substances -causing an enormous increase in moisture as well as volume. In this talk, we introduce a free boundary model modeling grain hydration. Asymptotic behaviors of free boundaries and the moisture content are obtained.
