Starch gelatination in the conditioner and extruder

Dear Dr. Sinclair, We manufacture an instrument (the RVA) that measures the degree of gelatinization (also at times referred to as degree of cook) in various types of extrusion products.This instrument is widely used in the manufacture of extruded breakfast cereals, snackfoods, and feeds. If you would like more information, please let me know how best to contact you. I can send you some application notes and other technical information. Best Regards, Wes Shadow Perten Instruments

Dear Dr. John Sinclair, As you have mentioned it can be measured by enzymetical methods. to do so you can easily use a Megazyme Kit called Starch Damage kit. I have already used it amd got a reasonable results for measuring starch gelatinisation. good luck
