2 dextrin/starch questions,


Recommended Posts

#1. What's the reason for cooking the corn starch into dextrin, or rather what happens if its not cooked enough or at all?

 

I couldn’t seem to find a good answer, but did locate this from one of Mumbles posts:

 

>>

The mechanism that breaks starch into dextrin is heat driven. The complex starch molecules are broken down into simpler carbohydrates that just happen to be glues. A similar process happens when boiling flour to make flour paste for pasting shells or what not.

My best guess is it's about the glues? and the corn starch isn’t as strong. Can someone answer this..

 

#2 And if the starch isn’t completely converted to dextrin, what how will it affect its use in pyrotechnics. ( granulated BP or stars)
