Polished rice was stored for 24 weeks at 28 deg C 2 deg C after infestation with rice weevil (Sitophilus oryzae), inoculation with a storage mold, or both treatment. The moisture contents of stored rice with and without rice weevil were 16.6% - 17.3% and 13.7% - 14.1% respectively. Fungal numbers were 4.3 x 10**6/g to 7.2 x 10**6/g with insects while no fungal growth occurred without them. There were considerable differences betwen rice weevil infested and non-infested rice in rice kernel hardness, 1000 kernel weight, maximum viscosity on amylogram, reducing sugar content, fat acidity, and n-hexanal content in head space gas
