Abstract
: Effects of ethanol on the aerobic plate count, weight loss, sensory evaluation, relative electri鄄
cal conductivity, total phenol content, chlorophyll content, polyphenol oxidase ( PPO) activity, and
phenylalanine ammonia鄄lyase (PAL) activity of fresh鄄cut broccoli were determined in this study. Effects
of different ethanol concentrations on the physio鄄biochemical metabolism were analyzed. Results showed
that the ethanol treatment could maintain the texture of fresh鄄cut broccoli, delay the nutrients loss, and
restrain the activities of PPO and PAL to effectively improve the storage quality and extend the shelf life of
fresh鄄cut broccoli.
Key words
: fresh鄄cut broccoli; ethanol; fresh鄄keeping; quality
