Moreover, parboiling can reduce the level of kernel breakage
during polishing (Buggenhout, Brijs, & Delcour, 2013). Parboiling
consists of three additional steps to rice industrialization:
soaking, pressure steaming, and drying prior dehusking. After
these steps, rice follows conventional processing steps. The main
phenomena that occur in rice during parboiling are: (1) the transfer
of bran components to the inner layers of rice caryopsis during
the soaking step, (2) inactivation of lipases due to heat treatment,
and (3) starch gelatinization (Demont et al., 2012).
