Thirty samples of rough rice stored for 6, 12 and 24 months in government authorized warehouses of the state of Rio Grande do Sul, Brazil, were simultaneously collected. After milling of the product, 90 samples (30 of polished rice, 30 of rice bran and 30 of rice hull) were evaluated for their mycoflora, aflatoxigenic species and aflatoxin contamination. The following fungi, listed in decreasing order of frequency, were isolated on Potato-Dextrose Agar: Aspergillus spp., Nigrospora spp., Penicillium spp.; Fusarium spp.; Mucor spp.; Cladosporium spp.; Trichosporon spp. and non-sporulated fungi. The degree of fungal contamination (colony forming units per gram of product) was lowest in polished rice, increasing progressively in samples of rice bran and rice... |

Rice aging is an important characteristic for cooked rice. Aged rice is needed by consumer especially Thai people and other people in the world. It takes at least 4 months to age rice. Accelerated aging of rice can be done by heating. This research used a continuous microwave of 1,000 watts to accelerate aging of milled rice cv. Patumthani 1. The initial moisture content of milled rice was 13%. The milled rice was treated with microwave by using speed number 4,5, 6,7, 8 (speed 0.0164, 0.0233, 0.0269, 0.0287, 0.0318 m/s) with the time of heating 34.85, 24.43, 21.17, 19.22, 17.91 seconds per round. The test was done for 1, 2 and 3 rounds and the other is not treated with microwave (control). The rice is stored at room temperature (28±2 ºC). The milled rice... |
