[Comparative study of extraction of corn stigma polysaccharide].
OBJECTIVE
To study enzyme treatment, transonic and a combination of the two processes for the extraction of corn stigma polysaccharide.


METHODS
Enzyme and ultrasound-assisted extraction conditions were optimized respectively through orthogonal test. A combination of the two methods was investigated.


RESULTS
The combined method was more efficient than the enzyme treatment and transonic individually. The enzyme-assisted process was in the medium level in compare of the other two.


CONCLUSIONS
The combined method was the most favourable one.
