.3. Proximate analysis
The moisture content of the rice samples was determined using a drying oven set at 105 ± 3 °C, with natural air circulation for 24 h, following the recommendations of the American Society of Agricultural Engineers (ASAE, 2000). Moisture content was expressed as percentage (%). Fat content was determined following method 30-20 of the American Association of Cereal Chemists (AACC, 1995). Nitrogen content was determined according to AACC method 46-13 (AACC, 1995), and the protein content was obtained using a conversion factor of nitrogen to protein of 5.95. Ash content was determined according to the AACC method 08-01 (AACC, 1995)
