2.1. Sample preparations
The laboratory analyses were performed in the Rice
Research Institute of Iran (RRII). The evaluated rice variety,
Hashemi, is one of the common varieties of rice in north of
Iran [26]. This variety is categorized as long kernel rice
according to the standard provided by the Institute of
Standards and Industrial Research of Iran (ISIRI, 2012).
Rice moisture content was determined by means of a
digital moisture meter (GMK model 303RS, Korea) to be
11–13.5% (w.b.) for the evaluated samples.
