Sorry - that was meant to be a private message to Amanda!
Amanda,I have a FB site where people post about archaeological diets and archaeobotany and anything in between really! I think there was a guy on it lately who posted about starches. Want me to ask him?Nikolah--On 23 April 2013 06:37, Amanda Henry <[log in to unmask]> wrote:
AmandaHello,I'm wondering if anyone on the listserv has used sodium polytungstate to try to separate partially gelatinized starches from sediment samples. We've been doing some experiments with modern materials and have found that SPT at 1.8g/ml seems to preferentially float native starches, leaving the partially gelatinized ones in the pellet. Has anyone else run into this problem? Any suggestions for a better method?
Many thanks in advance,
