dc.description.abstractThe invention, coffee grounds oil as stabilizing agent, relates to the use of oil extracted from coffee grounds, which is a waste product, as a stabilizing agent for polymer matrices exposed to ionizing radiation. Coffee grounds supply in average 11% oil. Films produced with oil in a polymer matrix have been shown to be homogeneous and stable against ionizing radiation, in a sterilization dose (25 kGy), when oil extracted from coffee grounds is added in a concentration of 0.5% by mass. Viscosimetric tests have shown approximately 67% protection of the polymer matrix with the above oil concentration. Mechanical tests have shown that neither rigidity (modulus of elasticity) nor mobility (elongation at break) of the chains were affected by gamma radiation when oil extracted from coffee grounds was added to the composition.
