d. Perform insect removal tests on the radio frequency pilot prototype to determine effectiveness,
e. Physical, chemical and sensory assessment of the changes that radio frequency treatments produces in rice.
f. Define the technical specifications and requirements that have to be met by the future RF team.
g. Disseminate the results.

Contexte
The project represents an important step towards reducing the risk of insects developing in postharvest rice, using a physical residue-free technology. The technology to be prepared is based on the industrial application of dielectric heating to eliminate insect infestations in cereals and/or other grains. Dielectric heating raises the temperature of insect larvae that develop within the grains more easily than that of the grain itself. This allows the elimination of pests without changing the properties of the cereals, with moderate energy consumption and potentially avoiding the presence of pesticides in the end product.
