Commercial WF (control) was purchased from the local market.
Freshly milled raw RB was collected from a local milling industry
(Bekas Agro SA, Thessaloniki, Greece). The RB was originated after
the whitening milling progress of the grains of a Greek variety
“Olympiada” (indica type). The grains were delivered to the industry
by rice growers, while normal agro-practices were applied
for local rice cultivation, including the application of herbicides
until the tillering stage of the plants. After RB was provided by the
industry, it was immediately stabilized in a laboratory oven at
120 C for 10 min in order to inactivate the lipase. The stabilized RB
was left to cool down at room temperature, then it was airtight
sealed in aluminum bags using a vacuum sealer and stored at room
temperature (25 C) and at 4 C for 4 months, in order to study the
effect of time storing at different temperatures. Results showed that
oxidative rancidity of RB could be prevented by heating, and storing
at 4e5 C for up to 4 months or at 25 C for up to 2 mon
