Do not exceed 150 degrees while steeping? Really?

[Alien Traveler]

I have read about steeping a lot. I am somewhat surprised by suggestion do not exceed 150 degrees while steeping. Why so? We use mostly food grade flavors that shoud be perfectly safe to at least 215 degrees.
Where I am wrong?

I think for nic users like myself there is concern about chemical interactions or possible degradation of nic. just from what I've read. I'm new to DIY so I have been researching steeping methods, hot water bathing for now.

I have often wondered about that as well. Some have suggested a temp above 150 will cause sugars in the juice to caramelize. I kind of doubt that they do. Here is a thread where someone heated their juice in a microwave just to the point where it started "smoking." Although I wouldn't go that far, according to him, his juices are perfectly fine and taste better than ever. As for nic degradation, he reports almost minimal loss. Either way, you can always heat your juice without nic and then add later. I personally would be very very careful using the microwave and cooking my juice.

I personally prefer a thermos like this one rather than a crock-pot or a microwave. It does a beautiful job.

Sure, cook the liquid. Then refrigerate it to preserve the nicotine. I think I got that right.

Could that indicate your are skeptical ....?

No. Temperature of caramelization is much higher. Well above water boiling temperature.

Except for fructose which I think caramelizes at 110

 

[Wraith504]

Mine generally steep in 190ish degree water from my kcup coffee maker.

Yes, you are right, it caramelizes at 110C which is above boiling temperature and is equal to 230 F.

I usually just put em to steep on a pan atop the George Foreman grill

I don't think it's a matter of whether the liquid will "survive" or not, but more of a matter of what it's going to do to the more volatile flavor components in the process.

 

[beardRage]

As long as your not doing it in plastic bottles and the water isn't boiling then you should be fine. I wouldn't want 150+ personally because that's gettin kinda warm and the whole purpose, as I understand it, is to get the liquids thinned out to speed up the mingling of ingredients. It shouldn't need "excessive" heat for this to occur.

 

[Nermal]

Oh, maybe a scoshie bit.

So much misinformation It's nothing to do with flavours or caramalisation, it's the nic that degrades at higher temps, pls spread the word to whoever told you those other 'facts'.

 

[rowdyplace]

Here is a good read. Yes, it is a little long, but it contains a lot of factual data...

In my opinion, it's making a mountain out of a molehill...so what if the nic degrades a fraction of a percent...hell I make mixes anywhere from 3mg to 18mg...the difference in a couple mg's of nic either way is so minuscule not to be noticeable...let along a fraction of a percent.

Sugars and Nic BOTH start to either metabolise or degrade or convert at temps above 150. You come up with correct term, regardless they start CHANGing Note the word START. This is the point where the process is starting. At 215 or boiling point of water, things are starting to VAPORIZE, and accelerating the conversion and degradation of the chemicals in the juice.

How much sugars are actually in the juice that could start to carmalise? Do people still add sweeteners to juice? I mean, is a majority of the professional juice we order and get at local shops have added sugars/sweeteners... Or do they just get their sweetness from the flavors themselves (any maybe even VG).

Where do you think the "sweet" of E-fluid comes from???? Sweetners Don't really have top be added in mixing, The PG and VG is quite sugary all by itself.

150F was an established baseline when testing was done comparing crock pot to ultrasonic cleaner steeping over in the ultrasonic steeping thread. It's really just a tested suggestion that showed good positive results. There's nothing to say you can't steep at higher temperatures. There just haven't been any controlled test done on anything higher then 150F. So basically any other information on this is pure speculation.
