Thank you for that informative and well written reply. I actually have contacted most of the universities here in the San Diego area. I have also contacted several food additive manufacturers, gum producers, and food packaging/distributing companies. All told, I've sent nearly 160 emails and left countless phone messages.
The REALLY annoying thing is that not one person has responded. It's really really strange. I even resorted to contacting food development companies like Mattson and PTM to offer payment for services rendered. I don't have a bunch of money to throw at this, but it's more a mission at this point. Unbelievably, they (Mattson/PTM) forwarded me to one of their "specialists" voicemails. No call back! I deal with customer service daily, and know I'm being polite to all these people so it's rather frustrating.
I also have a friend (Lead Scientist) at the USDA, and he has made inquiries with several colleagues. None of them take products past the lab and typically don't deal with quantities less than 'gallons'.
At this point I will take any somewhat reliable contact and pursue it. If you think contacting Cornell's Cooperative Extension for a referral in San Diego is a possibility, I'm totally game.
I'm not even worried about the packing aspect right now. I'd just like a stable emulsion, and I'd be a happy camper. I can work on the other stuff later.
As far as small scale producers locally, perhaps you can provide a more lucrative search term than I've been using. The best results so far have been from "food product development," but that usually gets me companies like Mattson.
Thanks for the help. This has been more communication from someone with insight than I've received from the 160 emails and phone calls sent.
