Hi all, over the past couple weeks we have sent out non-detect material (LOQ < 0.02%) to be distilled for aesthetic purposes (color and consistency improvements). While we have used several different distillers, our material has come back between 0.1% and up to 2.0% THC. We are trying to find the reason as to why this is occurring. Because of the low yield loss (< 5%), we are assuming a conversion is occurring.
A few additional details:
Very slight solvent (methanol and water) remains in the material being distilled
Kept it under 190 C degrees all the time
Pressure between 50-70 micron
Residency time between 6-10 hours
Any help or guidance from the community is appreciated. Thanks!
Hi @Siosis sorry this was confusing. We receive remediated distillate with a dark color and residual solvent, and we send it off for distillation for color and clarity improvement. The material is tested before sending it to distillation and after. The THC potency increases from below 0.02% to the mentioned range of 0.1 - 2.0%.
We are trying to figure if we should keep using a post processing distillation process to get the color and clarity improvement results? If so, is there something else we can ask our distillation guys to change to lower the chance of conversion?
Is there any other recommendations about how to improve the color and clarity without having it distilled? Like a color remediation service or process?
