Best tobacco for flavor extraction

[Boxster]

Thanks for the link aces. After reading down through the article, if I read and understood correctly, after the distillation/extraction process, a high percentage of nicotine was also extracted.....

Quote:

"The method used to extract the essence from the stems also removed from 84
to 93 percent of the nicotine contained in the stems. Data on removal of
nicotine are included in Table 3.
If the extract is to be used for enhancing smoking tobacco, the additional
nicotine may be objectionable unless only a small percentage of the extract
is required."

Just wondered if a method of super concentrating tobacco extract i.e. reusing a previous pga extract to produce the next batch and the next and the next. Especially if one were super concentrating a N. Rustica type. Just a thought.

The article also stated that the essence produced very favorable aroma's.

The way I read table 3, nicotine content of the essence varies from 1.92% to 7.14 % depending on the tobacco. They do not indicate which method of extraction for those numbers, but if it is alcohol, an average 5% of essence in the final mix will add .03% nicotine at the most.

It appears to be alcohol extraction from 1k grams of tobacco stems.

Trying to figure out why they used benzene to remove some compounds from the extract. Does anyone know?

^^-- in 1951 they weren't afraid of benzene.

Hi all! I don't usually have much to say here because I don't DIY very much. I've had a few spells of DIYing that went pear shaped and all that macerated Cuban cigar I made 2 years ago found its way down the slippery slope of juice heaven.

However, I have made the most of the big liquidation sale Diane was having at MyVapeJuice and purchased 4 blowout boxes of the extracts. In the boxes there are pipe tobaccos, cigar tobaccos and teas.

It is a lot of extract, more than I can ever hope to mix and vape.

Any tips, hints, pointers, techniques on how best to mix Diane's extracts to deliver the best flavor and performance would be appreciate.

I am considering mixing the type of extracts in the following ratios:

Pipe tobacco 20%
Cigar tobacco 25%
Teas 25%

Does this sound about right?

One other question I have regards storage. I am going to transfer the extracts from plastic to glass bottles to preserve their lifespan. I am also considering putting them in the fridge as we have summer coming in Australia and it can get quite hot inside my house when I am at work and the air conditioner is not running. My question is, can NET extracts be stored in the freezer without the juice being negatively affected ?

I got 1 box. Ironically with this huge pile, I'm trying lower percentages. Her recommendation was 25-30% and that's probably good for small clearos but for dripping I'm now trying <10% ; shake and vape that's very light, but flavor should develop with steeping. I'll probably try some mixing with synthetics eventually, which could work out to 2% extract, .1% synthetic.

I posted this awhile back in the NET thread, but maybe here is a better spot. It's an article on the distillation of tobacco macerations. I've wondered about this. Thoughts?

Interesting read although pretty short for an exploratory research report, these types of people are usually ~overly verbose~ when delineating their work. It appears they were specifically after fragrance (tobacco extracts primary industrial use) although they did note the connection between smell and taste. For their experiments they used low grade tobacco and or stems which might have had an effect on their results. Even so, one must keep in mind this specific study focused on obtaining tobacco fragrance, not flavor.
"This laboratory undertook the study of "essence" recovery because it was felt that it might be used to..... impart a tobacco aroma to paper, wood, or similar material used in packaging tobacco products." - "Since odor and taste are interdependent, many investigators have studied the essential oils of tobacco flowers and leaves and the resins in tobacco which contribute to the over-all tobacco aroma."


They tried using water as the extraction solvent, first in a simple soak then through steam distillation. They weren't pleased with the results. This doesn't surprise me because my experience with steam distilled tobacco essence is that the extreme heat required (>220F) alters the flavor that's produced. While it does still impart a tobacco-ish flavor it's non-descript and difficult to discern one type of tobacco from another. Pretty potent though.

"literature cited on the study of essential oils of tobacco indicates that the best method of obtaining an essence would be to steam distiH the tobacco or extract it with water, distill the extract so obtained, and concentrate or extract the distillate. Aqueous methods were therefore studied first. This study also compared the efficiency of other organic solvents, not mentioned in the literature, for recovery of tobacco essence. The purpose was to find the best method of obtaining an essence."​

"Aqueous Methods; Two general methods were employed water leaching, with subsequent distillation of the extract, and steam stripping. The panel used in evaluating the fractions agreed that none were very nearly like the control in quality."

"The inferior results obtained from the aqueous methods indicated that an organic solvent method should be developed."


Not happy with water based extractions they turned to experimenting with other organic extraction solvents. Of all the solvents they tried they preferred the results obtained when using 95% Ethanol (PGA).
"Solvents used were chloroform, benzene, ethanol ( 95 percent), methanol, acetone, t-butanol, and i so-propanol"

"Ethanol extraction produced the most representative essence concentrate"

"The best aqueous essence was compared with the solvent-prepared extracts. The solvent extractives were superior."

I found it quite interesting that of all the solvents they tried Ethanol was identified as being the best for extracting essence from tobacco. Even more interesting is that they determined 12 hours was the optimum soak time for complete extraction and 78° C (right at Ethanol's boiling point) was the processing temperature. They even reduced/concentrated the finished extract by 90% although they distilled (rather than evaporated) the ethanol off so they could recover and reuse it.
"It can be seen from the table that the time required for complete extraction is approximately 12 hours."

"......78° C, The alcohol was immediately drained off and added tp the first extract. The extracts from several batches were accumulated and concentrated to approximately one-tenth the original volume by distilling off the alcohol..... The recovered alcohol was used again in subsequent extractions."


They noted that Potassium nitrite crystals would precipitate out of solution upon cooling of an Ethanol based extract. I wish they had gone into more detail describing this occurrence. They make no comment about natural oils falling out of solution after reduction which as we know they do with the extracts from most types of tobacco.
"In all extractions with ethanol, potassium nitrate crystals precipitated upon cooling."

It would be interesting to read through some of the literature cited in this study (listed at the bottom of their report) if any were still available.

a little more of this sign in codes, vitrification's and passwords and we won't have to many left!

For those interested.

P&C has Lane Limited aromatic 1# bags on sale for $25.00.

Just ordered a pound of the 1Q.

RO Series Perique Blends

​

Russ always has his hands full with tobacco, and quite often something great happens. But sometimes the stars just align and he creates something very, very special. He was able to get his hands on Perique varietals from the small farms that process this very special leaf. For the first time Perique from the four distinct regions were stored in barrels and left to ferment. Russ is the only blender who had access to these very special varietals. To highlight the different regions, he created the RO Perique Series to showcase the distinct characteristics of these tobaccos. For the full story on how he created the series and an explanation of the four regions of Perique, and just how special this project is, click Shop Now.

The thread may not be active, but I am. Got 10 going through the reduction process, and pound of Lane 1Q to start on at some point in the future.

I have several "new" tobacco blends in play but am experimenting with a long term room temperature ethanol based extraction process so it'll be another month or two before results are in. The good news is that many "new" tobacco blends have recently been released so I'll have new material to work with this Winter. Daughters & Ryan "Picayune" and Cornell & Diehl "Orion's Arrow" are two blends I look forward to trying. I'm currently extracting -large- batches of my favorite tobaccos and intend to see if a concentrated extract can be stored in the freezer alongside liquid nic.

Lane 1Q was my favorite tobacco back when I smoked a pipe and was the first tobacco I extracted for NET because I had several pounds of it on hand. Unfortunately, for me 1Q's extracted flavor was just too subtle, I hope you have better luck with it.

Daughters & Ryan "Picayune"

Just started a D&R Picayune today, along with a P. Stokkebye 84 Turkish and H&H Anniv. Kake. All the while, enjoying the heck out of some P. Stokkebye 306 English Oriental Supreme.

I had a nice moment last night..... when my Daughters boyfriend, who is wanting to quit smoking and try vaping, took a hit off my dripper loaded with the P.S. English Oriental..... His eyes lit up like a kid seeing all the gifts under the Christmas tree! He was immediately sold on the idea that NET could replace his cigarettes!

I've already made some and am enjoying it. I do add a little caramel and vanilla to bump it up a little.

That's -exactly- how I was "introduced" to vaping, you see how it turned out for me

I only wished I had found out about NET sooner than I did.

Think I'll give the C&D Haunted Bookshop a try, for being able to tell future Vapers that I have exactly the NET juice they need to remind them of their cigarette tobacco; Burley heavy, Virginia & Perique.

I wasn't trying to quit smoking or even looking for something different but when I was introduced to vaping NET (hybrid-NET) the tobacco lover in me enjoyed the experience enough to buy vape gear and retail NET. Once I was set up and going I never lit another pipe, wasn't really my goal it just worked out that way. I'm glad it did.

I've already made some and am enjoying it. I do add a little caramel and vanilla to bump it up a little.

I only vape hybrid (flavored) NETs and Flavor West "Caramel Candy" is my favorite caramel flavoring but I usually add a little TFA "Caramel Original" in with it, around 75/25. I have a wide assortment of flavorings just for NETs, it took me years to find all the specific flavors I was looking for. I actually like a vanilla tobacco best but unfortunately I lose the ability to taste vanilla within a few ml so Caramel is my go to.

I have a few more batches of wholeleaf tobacco going.
Cold extraction in a 70/30 vg/pg base. Takes about 8 weeks before filtering.
The ones I have completed so far has been great. Nice pure tobacco taste. Now my ADV
