More About Prolamins

Prolamins in Grains
Grain Prolamin percentage
Wheat Gliadin 40-50
Barley Hordien 35-45
Rice Orzenin 5
Oats Avenin 10-15
Corn Zein 50-60
Rye secalin 30-40

These are the grains which I have been able to find the names of the prolamin protein and the percentage of protein in the grain which is prolamin.
It is easier to find out how to extract prolamin from other grains than to find the names and percentages. For those that are interested, refluxing in alcohol will do the job but the key thing here is that all grains contain prolamins. These have been implicated in autoimmune diseases.
