| Research Abstract |
High pressure treatment, being able to activate secondary metabolic reactions in the plants, will lead to establishment of a technique for obtaining the food material of high quality. In this study, an agricultural material was selected and treated with high pressure. And the processed sample was stored for 4 days at 25 C. In onion samples, its radical scavenging activity increases have been shown, because quercetin inside increased during storage after the high-pressure treatment. The high-pressure treatment damaged the tissue structure of cellular biological material first, and mass transfer in the material was promoted. Therefore, the association of substrate and enzymes involved in quercetin generation was considered to be raised, and quercetin concentration was increased as a results.
