When the cannabis plant is subjected to extraction, the end product can contain cannabinoids, terpenes, oils, waxes, lipids, proteins, and other plant material. The total amount of product has little to do with the actual value and efficacy of the product. The composition, or fraction of each component of the whole, really determines the potency, effect, and value of the extract. For example, Extract Company A processed 10 lbs of cannabis and obtained a yield of 20%. However the end product contained 20% THC. Extract Company B took the same feedstock and obtained a lower 10% yield but the final product contained 60% THC. Which extractor is better?
If we look at “yield” alone, Extract Company A beat out Extract Company B. But what if the product from Extract Company A contained more waste material thus increasing its final mass and the resulting yield? “Yield” is important, a processor should measure how much comes out of the process compared to how much goes in. However, a much more critical evaluation is what is called the “Extraction Efficiency.”
Extraction Efficiency is the amount of THC actually extracted, versus how much THC is available in the feedstock. A 100% Extraction Efficiency means that 100% of the THC in the feedstock is being extracted. In the example above, let’s assume the feedstock contained 10% THC by mass, thus 1000 grams of feedstock contains 100 grams of THC. Extract Company A obtained a “yield” of 20% (the mass of the material coming out of the extraction equipment is approximately 20% of the mass put in to the extractor) or approximately 200 grams of material. However, based on the potency of 20%, only 40 g of THC was extracted (20% of 20% of 1000g).
Using the same material, Extract Company B obtained a 10% “yield” – or approximately 100 grams of extract (10% of 1000g of feedstock). However, that 100 grams of extract is comprised of 60 grams of THC (60% of 10% of 1000 g of feedstock)– 50% more THC for the same amount of feedstock than the extract of Company A.
Although Company A obtained a higher yield, the Extraction Efficiency is 40% (40g THC extracted of the total 100 grams available in the feedstock).
Company B obtained a smaller yield (10% compared to 20%), but the Extraction Efficiency is 60% (60g THC of the total 100 grams available has been extracted).
As most products are sold based on their THC content, the extract from company B is a much more profitable and efficient extraction process. The extract from Company B contains more useable, saleable THC from the same plant material. Thus there will be a higher number of products that can be made.
As you can see from the examples above, “yield” is important, but has very little do with the actual effectiveness or efficiency of the extraction process. The key is Extraction Efficiency, the amount of THC actually extracted, versus how much THC is available in the feedstock.
With taking the risk of throwing $$ @the problem....consider this?
tCheck 2 is a potency tester that allows you to measure the strength of your infusions. Using just a few drops of butter, coconut oil, olive oil, or alcohol, you can accurately measure the strength of your infusion in less than 45 seconds.
Results from tCheck 2 will be an aggregate of all compounds combined. For a separate measurement of the compounds, Compound Breakdown Subscription will be required.
100 milligrams of your cannabis medicine a day. Hmmmm
A gram has 1000 milligrams.
Your bud is 1% THC and 9% CBD.
Lets assume your extraction pulls out all the cannabinoids....so your extract will still BE 1% THC and 9% CBD, just in concentrate form.... hmmm...time to and then I might work it out hehehe
