Effect of different factors on RVA profile characteristics of germinative lotus seed powder

Rapid viscosity analyzer ( RVA) was used to determine the effect of different factors on RVA profile characteristic of germinative lotus seed powder.Compared to germinative lotus seed powder, the RVA characteristics of ungerminative lotus seed powder and the effect of sugar, blend oil, mesh, dextrin were well described by the graph of RVA under warming program std1.Then the correlation of these factors and properties of germinative lotus seed powder was analysed.The results showed as follows: with concentration of germinative lotus seed powders increased, the Peak- Viscosity and aging rate was increased prominently; content of sugar and oil had a sigificant effect on RVA profile; Dextrin and sodium chloride didn't have much effect on RVA characteristics.
