Resumo: 	A work was carried out with the purpose of verifying the biochemical changes associated to soybean (Glycine max (L.) Merrill) seeds osmoconditioning. Seeds of the UFV 10, IAC 8 and Doko RC cultivars harvested at R8 development stage and submitted to different treatments were used. The biochemical evaluations were performed during seed storage, after the hydration-dehydration process. Initially, seeds were osmoconditioned in a polyethylene glycol (PEG 6000) solution, with the osmotic potential of -0.8 MPa and 20ºC, for a period of four days. After that, seeds were dried back until the initial moisture content (10-11%) and stored in natural conditions for three and six months. Two controls were used: untreated seeds (dry seeds) and water soaked seeds. Seed changes in protein and lipid, hexanal accumulation and fatty acids contents were evaluated. The results showed that seed storage under laboratory natural conditions caused reduction in protein, lipid and polyunsaturated fatty acids content and promoted hexanal production. Storage periods reduced protein levels for all treatments, however the PEG 6000 treatment showed lower protein reduction. The soybean seed storage increased hexanal production, but hexanal levels were smaller with osmoconditioning comparing to the other imbibition treatments.
