Assessment of rice (Co 51) seed ageing through volatile organic compound analysis using Headspace-Solid Phase Micro Extraction/ Gas Chromatography-Mass Spectrometry (HS-SPME/GCMS)

Seed ageing is an inevitable process that reduces seed quality during storage. When seeds deteriorate as a result of the lipid peroxidation process, it leads to produce toxic volatile organic compounds. These volatiles served indicator for viability stored seeds. With this background, study was conducted profile compounds emitted from rice Volatile profiling var. Co 51 done through Headspace-Solid phase microextraction/ Gas chromatography-mass spectrometry (HS-SPME/GCMS). The clearly demonstrated significant decrease in physiological and biochemical attributes noted due increase strength released ageing. release total reached more than 40%, reduction such germination, root shoot length, dry matter production vigour index were observed. respect properties, electrical conductivity leachate, lipoxygenase activity, dehydrogenase, catalase peroxidase activities However, highest all these properties recorded when 54.90%. Finally, concluded that, among volatiles, 1-hexanol, 1-butanol, ethanol, hexanal, acetic acid, hexanoic acid methyl ester most closely associated with deterioration. It indicates components could be considered signature assessing
