Abstract: The bio-activity of three enzymes from vanilla capsules,seeds and peels have been analyzed. The results show that the activity of β-glucosidase in seed is much higher than that in peels. The activity of peroxidase in seeds is zero,but in peels it is at a high level. The activity of polyphenol oxidase in 5 samples are all at a very lower level.
