Abstract: TIn order to explore the fresh-keeping effects of different Chinese herbal extracts on fresh-cut broccoli, fresh broccoli was dipped in extracts from honeysuckle and cloves as well as the mixture for 15 min, respectively. The samples dipped in distilled water for 15 min were used as the control. These samples were stored at (15 ± 2 )℃. The effects of different treatments on physiological and biochemical changes of fresh-cut broccoli were also investigated. The results showed that Chinese herbal extracts could improve the sensory quality, inhibit the respiratory intensity and weight loss, delay the decline of titratable acidity, vitamin C and chlorophyll contents. The honeysuckle extract revealed the best fresh-keeping effect and could significantly (P<0.05) improve the fresh-keeping effect of fresh-cut broccoli compared with the control.
