[Study on industrialization production technology of decoction pieces shuangfei of Platycodon grandiflorum].

OBJECTIVE

To establish industrialization production technology parameter for decoction pieces shuangfei of Platycodon grandiflorum.

METHODS

Taking platycodin D, polysaccharide and the appearance of the decoction pieces shuangfei of Platycodon grandiflorum as the quality evaluation indexes, we investigated the size of Platycodon grandiflorum, the best slicing extent, the best slicing thickness, drying temperature and drying time.

RESULTS

The optimal processing was as follows: the diameter of Platycodon grandiflorum was about 1.5 cm, moistend the selected Platycodon grandiflorum until the water content was 55% - 60%. Then rolled them into 1.5 cm thickness pieces. Dryed them at 60 degrees C for 8 - 9 h and packed them after they were cold.

CONCLUSION

The industrialization production technology for decoction pieces shuangfei of Platycodon grandiflorum is stable and the efficiency is improved.
