No! Under NO circumstances should you boil pre-hopped extract,unless you wanna turn the flavor additions to bittering. not even 10-15 minutes. Not ever. Besides,pasteurization happens at 160-162F,NOT BOILING. I don't know how many times I've said it. Do not boil pre-hopped extract,do not use it in the boil. Use some plain DME in the boil,as it doesn't caramelize ant where near as fast as LME. I add pre-hopped extract at flame out to preserve it's flavor/aroma hop profile. Then steep for a couple minutes to pasteurize,as it's still boiling hot when the flame out additions are added.
Pasteurization happening at the LOWER TEMP of 162F will do the job in seconds.
