Binding by the enzymatic method of producing high purity films tea saponin art

The present invention relates to a process for the preparation of a film by the enzymatic technique combined with high purity tea saponin, wherein the following steps performed: a, using ultra-fine grinding technology, pulverized tea seed meal; B, step a substance in the water was added enzymatic hydrolysis; c, the enzyme solution obtained in step b, and was centrifuged; d, the supernatant obtained in step c, through an ultrafiltration membrane to give a crude saponin; E, will concentrate in step d readjusted slightly alkaline, using an ultrafiltration membrane and concentrated for further processing 2, during filtration, pure water is added intermittently dilution; F, step e and the concentrate was spray-dried to obtain the product. The present inventive process is simple, efficient scheme, product safety, more efficient use of available resources tea seed cake, prior art solution is not high yield, inadequate purity, environmental pollution problems, to provide a safe environment for the maintenance, naturally degradable surfactant sources.
