Influences of enzymatic exfoliating technology on the quality of gelatinous candy produced by passionflower peel

Producing gelatinous candy with passionflower peel pulp as raw material is a good way with great commercial potential to improve resource utilization. In order to solve the current problem of rough taste and texture of the product，the paper studied complex enzymatic degradation technology of horny substance in passionflower peel pulp，through orthogonal experiment， the optimum enzymatic degradation parameters were obtained: the peel pulp pH was 5.5，cellulase concentration was 2.5 mg/g，hemicellulase concentration was 1.5 mg/g，the ligninases concentration was 1.0 mg/g，the degradation process lasted for 4 hours at 35℃. The enzymatic treatment could reduce roughness，improve the dissolution rate of pectin from the pericarp tissue，most important，the technology degraded about 50% of the horny substance in the peel pulp. By the treated peel pulp，supplemented with sugar，gelling agents，we can produce a high-quality passionflower gelatinous candy，which was more pure，delicate and uniform in color.
