Abstract:The extract of radix sophorae subprostratae, myristica fragrans and its complex extract were prepared. The material liquid ratio was 1:10 (m/V). Broccoli was dipped in these extracts for 15 min, and with the distilled water as a control. Dry in the air. Then these samples were stored at (3±1) ℃. The effects of different treatments on the physiological and biochemical changes of broccoli were investigated. The results showed that any chinese medicinal herb extracts could improve the sensory quality, inhibit the respiratory intensity and weight loss, delay the decline of soluble protein, titratable acidity, vitamin C and chlorophyll contents, improve the cell membrane permeability, and decrease the content of the MDA. The effect of the material liquid ratio of 1:10 radix sophorae subprostratae extract was the best and it could significantly (P<0.05) improve the fresh-keeping effects of broccoli compared with the control experiment.
