macromolecular compounds like starch can influence the dissolution of small molecule compounds in the decoction.This study was in order to investigate the effect of processing on starch by determining the basic physicochemical properties of starch in Pinelliae Rhizoma and Pinelliae Rhizoma Praeparatum. Method: The effect of processing on starch was evaluated by detecting the swelling degree
solubility and water binding capacity
crystal structure and micromorphology of starch in Pinelliae Rhizoma and Pinelliae Rhizoma Praeparatum. Result: There was no significant difference in microstructure between starch in Pinelliae Rhizoma and Pinelliae Rhizoma Praeparatum.Compared with starch in Pinelliae Rhizoma
swelling degree
solubility and water binding capacity of starch in Pinelliae Rhizoma Praeparatum were obviously decreased from 30.80%
17.22% and 10.56 to 13.93%
10.13% and 7.82
respectively;but the crystallinity of starch in Pinelliae Rhizoma Praeparatum was significantly increased from 31.77% to 55.11%. Conclusion: Processing can influence the physicochemical properties of starch in Pinelliae Rhizoma.Combined with our previous study
we speculate that the change of starch in Pinelliae Rhizoma is one of the reasons influencing the efficacy during processing.
