Congregation obtained after chitosan k and a treatments showed more tightness than sediments obtained without chitosan treatment, sediments after chitosan b and c treatments were network in structure. Mixed systems of pectin, protein and polyphenol were applied for studying a simulated system of kiwifruit juice.

Glycolate oxidase (EC 1. 1. 3. 1, GO) was purified by 137. 4 fold from leaves of Brassica campestris L. ssp. chinensis var. utilis and the specific activity attained 130.9 U/mg. protein. Chromatography of purified GO through Sephadex G-200 showed two symmetric peaks of both protein and activity, which overlapped fully with each other. Further with electrophoresis on agrose plate, a protein spot and an activity spot were detected in electrophoretogram after respective staining, and the spot of protein covered that of activity, which indicated that the purified enzyme was of a high quality.
