I'm not about to sidetrack this thread into a trub discussion but there is as many studies saying it doesn't matter as there are that it does. I have the ability to dump it from my conicals so I dump some, but certainly not all.
For a professional brewery it would take DAYS for all the trub to settle out in the conical even with Brew Tan B. So there is no reason to sweat over a small amount.
But this thread IS about trub. It's literally in the title. On a serious note I would love to see the studies you reference for it. I am always up for reading some good scientific studies.
I don't know that brewtan b is going to help break settle any faster( maybe it does?), but there are there many things a professional brewery can do with specialized equipment that we as homebrewers can't.

What I meant was I didn't mean for a small conversation on the detrimental effects of trub in a starter being dumped into a 5 gallon batch of beer to explode into a 20 pg rant about trub.
But if it is going to go there then....
The stuff I read was at least 15 years ago. I'd have to go find it. Look, I have no doubts about your booksmarts, Bryan. You have a far better grasp of the chemistry than I do (want a job?
) All I can say is that for many years I brewed sometimes three or four 12 gallon batches a week in side by side 6.5 gallon carboys. Many, many times I removed trub from one but not the other, and in the end, honestly, I wasn't sure I could tell a difference. Least it was very hard to blindfolded. Yeah, maybe it did. Then again maybe it didn't.
I firmly believe that attention to detail is what makes good brewers great brewers and if removing trub from your starters or carboys is the attention to detail that puts you over the top you should go for it! But do yourself a favor and at least try it first, side by side, to see what difference it makes rather than just b relying on something you have read on the internet. (And by YOU I mean the forum at large, not Bryan.)
BTW: You are correct as usual. Commercial brewers do have ways to remove trub. I have a centrifuge for instance, I just haven't gotten the curiosity to hook it up yet to my kettle/chiller. But it is in the works. But there are some great little breweries making some very good beer all over the world that don't have that ability.
