Adding spice powder to flour

Profile picture for user Mister Benny

Hi just wanted to ask 2 questions here,
1. does adding garlic and onion powder to flour when making instant yeast bread hurts the yeast or cause other problems?
2. If I puree and onion and some garlic with water in a blender and then strain the water, will that hurt the yeast or cause problems?
Thanks for any advice.

Wow thank you Mini I am a roasted garlic fanatic and had not thought of putting that in bread. 
Maybe some deeply caramelized onions too. THANKS!
