The Preliminary Study on the Forming Mechanism of Choerospondias axillaris Pastilles

The purpose of this study was to investigate the effects of the endogenous polysaccharides present in the Choerospondias axillaris(CA)flesh,exogenous polysaccharides,and oligosaccharides on the forming properties of CA pastilles. An optimal formula of CA pastilles was obtained. Pectinase and cellulase were used to hydrolyze the pectin and cellulose in CA flesh,and the exogenous polysaccharides were added,as well as sucrose was equally replaced by oligosaccharides to investigate their effects on the forming properties of CA pastilles by rheometer and texture analyzer. The results showed that both endogenous pectin and cellulose were beneficial to the formation of pastilles,and the effect of pectin was apparently stronger than that of cellulose. Only pectin among the exogenous polysaccharides could significantly improve the formation of pastilles. Samples with oligosaccharides added had a frequency dependence and were non-Newtonian fluids. In addition,,the appearance of sample only added with lactose and galactose changed from yellowish-brown color to white and its surface was agglomerated and became hard after drying. This indicated lactose and galactose could not be used as a substitute for sucrose to prepare Choerospondias axillaris pastilles.
