3.1. Hydration characteristics of brown rice with large germ
during soaking
As Fig. 2 indicates, the moisture content of Nipponbare
reached 35–36% after 24 h. In contrast, that of Haiminori
was greater than 35% after 2 h, and reached 43.6% after
24 h. The GBR products contained normal 30–35% moisture.
In raw wild rice, high moisture levels (35–50%) promoted
mold and bacterial growth (Lindenfelser, Ciegler,
& Hesseltine, 1978). The moisture content of Haiminori
GBR should be kept under 35%, similar to that of normal
brown rice.
