FIELD: agriculture, fat and oil industry. ^ SUBSTANCE: method involves sampling sunflower seeds, measuring their temperature and placing the seed sample into transducer of impulse NMR-analyzer, measuring nuclear-magnetic relaxation indices of protons in sunflower seed oil and calculating weight average value of spin-spin relaxation time (T2CB). If value T2CB < 1.8 x t + 19 then seeds are related to highly oleic ones. Method provides reducing time required for identification and simplifying preparing samples. ^ EFFECT: improved identifying method. ^ 1 dwg, 1 tbl |
