There are many variations in traditional methods of parboiling
depending on the place and scale of operation (Araullo et al.,
1976), but the basic production steps are hydration of the paddy
(to a moisture level 24–30% wb), thermal treatment to achieve
complete gelatinisation and dehydration to a moisture content
appropriate for milling. In large scale commercial parboiling processes,
variation in the processes is done to make it efficient, economical
and to improve the end product quality
