The values for vitamins retained by brown rice after spraying
and subsequent drying to safe moisture levels, are shown in Table 2.
The brown rice can absorb readily the vitamins to the same degree
like the white rice. It seems that the vitamins are cohered and/or
absorbed by the surface at the same level like the white rice but
higher than the gelatinized parboiled product. The average retention
varied from 85.3% for vitamin B1 to 60% for B3. Similarly, this
retention level is considered as satisfactorily high.
