In case you did not catch it on my Potato Hack blog, I just wanted to give a quick update on what I'm up to.
Resistant Starch Analysis Project
I started a fund-raising project to be able to test the resistant starch content in products like Bob's Red Mill potato starch, green banana flour, Hi-Maize and others. For years we've been using these products based on old research that showed these type of starches were high in RS. Most of the starches used in research are not tested for RS potency, and many of the RS studies show wide individual variations, mostly blamed on starting gut conditions. Maybe this variation is caused by differences in the RS being used.
Hi-Maize is the only RS product specifically made for its RS content. Potato starch and banana flour are made to be used in cooking, and the makers don't care if they have high RS or not. My "gut feel" is that potato starch and some others are very high in RS, but no one can say for certain. I've seen reports that other starches should contain high RS, but I was never confident enough to recommend them, ie. tapioca, mung bean, etc. It would be of great benefit to researchers and anyone who is interested in RS to have a database of RS contents of various starches.
Therefore, I have started this fund-raising project to get some money gathered up so that I could send samples of different starches to a lab for RS testing. Read all about it here:
Indiegogo Resistant Starch Analysis Project
The funding so far has been amazing, and almost all from blog readers. We've raised over $1000 in the first few days, enough to get some testing done. I hope to get substantially more. I've been contacting researchers and labs trying to drum up interest, but so far no one has donated from that crowd. Perhaps labs don't have flexible spending like the rest of us.
Each test will cost between $145-200, depending on which lab and what kind of discounts I can get. To make this meaningful, it would be best to test several samples of each starch.
So...I hate to beg for money, but if anyone is interested, just click the link above, check out the project, and donate if you like. The results will benefit us all. I'll be busy trying to get more funding for the next 60 days.
A couple people asked if they could donate using PayPal instead of the Indiegogo site, and you certainly may. Here's a link to my PayPal account if you so desire: Tim Steele's PayPal link.
I'll keep you all posted on the progress.
