Sure, basically the same question IMO. I suppose my thought expirament of the thread was intended more to be on the feasibility of these PPM limits themselves rather than a greater look at how to make the best concentrates.
In states like MA I think, at least to some extent, the ppm limits certainly fire up competition that’s for sure.
As macho man randy said “the cream will always rise to the top”
My live resin terp content usually ranges from 5-10% at the ppm levels i said above0 for most upto 100. I can’t find the nd level, I’ve looked everywhere, I will email and I will report back.
Yes this has been effective for me. Obviously don’t turn it up too hot or you’ll decarb, it really only needs to go up a little until you stop seeing any bubbling.
I was more talking about the rapid cooling part of your process. Is it just for the purpose of saving the extract that you’re cooling it down or is there something not obvious happening?
You don’t want any extract at temp for too long, just limits the time it’s at temperature. You don’t want any thca to decarb. If you’re going for shatter it’ll also keep it stable for longer in my experience.
Call Precision and we can get you dialed in. We regularly teach clients how to retain 15+% terpene content while simultaneously receiving RSA results under the LOQ in all regulated markets.
We are seeing this here in Michigan but with vitamin E acetate regulations. I happen to know one of the lab directors who worked with the state in prompting and figuring out these regulations. It starts by identifying the problem, where it came from, and whether or not the findings can be applied to a spread of products from the same market. For example, if the mystery peaks on the chromatograms from samples in question are seen in more than just one sample then it can be added to the list of things to identify and regulate.
I expect you would begin by looking at what most people are spraying their machine trimmers with to keep them lubricated. Maybe the companies that make these things supply the lubricant which would be a good place to start? Then start to build a database of what people around the country are using and develop standards to test for them. The vast majority of mystery oils - in my experience - come from lubricated machine trimmers
This is incredibly difficult as we are still discovering new cannabinoids. Also - to my knowledge standards for things like D10 THC and other cannabinoids aren’t widely available yet
I heard Cerilliant had a D10 standard, but a quick search did not locate it.
Might be something you have to call on.
@AlexSiegel should also be able to respond.
Bumping this to see if anyone else has thoughts on quality live BHO passing residuals @ 1ppm.
Considering taking a job where hydrocarbons are the only extraction in MA for strictly fresh frozen of outdoor material…
Use propane
Use terp extraction equipment to pull the Terps out first then extract for the thca with propane and the re combine to whatever formulation your heart desires.
You can crystallize thca in botanical terps instead of recognized solvent
This would be my play
wow. good luck with that…
getting down into the 100ppm range isn’t too rough on your extracts, but the 3rd party lab we’re currently using has their LOD at 1000ppm because OR decided 5000ppm butanes was cool for huffables…
the lab I was using for R&D had their LOQ at 100ppm and LOD at ~80ppm. about 1/2 my samples showed non-detect.
having in-house analytics so I could actually see what each stretch in the vacuum oven was doing to my terpene profile vs the residual solvents was extremely helpful.
I would keep the temps down, and run a controller on the vacuum (or at least a real gauge). separate your HTE and purge the fractions separately (you won’t need to be as gentle with the THCA).
SRI 310MM was able to see butane & propane in the samples that were ND (below 80ppm) and should be able to guide you to the range you’ll need. Along with a providing a qualitative look at your terpene profile. to achieve quantitative, you’ll need more. I’ve got a couple of headspace auto-injectors, and getting quantitative headspace on my terpenes & residual solvents is on the list…but I’ve got a huge list of projects with higher priority atm.
I’m sure I can dial in something to get to ND, I’m just wondering what the final product will taste like.
I’m leaving corporate hell in search of a job to make something I care to smoke, you know?
We have some SOPs to reach ND and preserve terpenes, definitely a more costly and time consuming process but it is possible.
good calls.
limonene is usually the first suggestion…Using Limonene as an alternative to hexane for CBD Isolation
although there are probably better options.
This could indeed be another source.
Still I believe those “mystery oils” are more likely to originate from the extraction solvent.
If I was in your position I would take all my extracts into a crumble form and then post process beyond that into shatters/sugars/thca isolates ect. seeing as you can hit 5 ppm with a crumble sop without ruining the terp profile in the oven.
