[DYSPHAGIA] blue dye

[ShariEllen@aol.com (ShariEllen@aol.com)]

I use regular supermarket blue dye (next to the vanilla extract!) during 
FEES-type exams with our ENT in the nursing home.  It turns vanilla pudding a 
lovely aqua, and thickened apple juice a nasty shade of greenish yuck.  

Has anyone experienced allergies with this stuff?  I use about one drop per 
few ounces of food.

Does Evans blue offer something that food-blue does not?  Is it the same as 
methelyne blue?

Best,
Shari B
