I'm currently preparing some canna-butter in a double-boiler, and the cooking-thermometer in the butter shows the temp to be between 188 and 193 degrees Fahrenheit, as is recommended in BadKat's recipe for Chocolate-Covered Peanut-Butter Canna-Bombs. (This is my first time using this recipe, my sixth time cooking with herb, & my first time cooking with a thermometer & a proper double-boiler... So although I'm Ol' School, I'm still a noob when wearing the Chef's hat.) I'm very familiar with vaping, and understand that THC does not vaporize from the herb until 300.7[FONT=&]°[/FONT]F (149.3[FONT=&]°[/FONT]C), with CBD & CBN vaping from bud at about 403.3[FONT=&]°[/FONT]F (206.3[FONT=&]°[/FONT]C) & 414.9[FONT=&]°[/FONT]F (212.7[FONT=&]°[/FONT]C) respectively. Now, I know that THC extraction via liquid fats is completely different from extraction via heated air, but I do have some confusion regarding those differences... I guess I'm wondering how or why 180 - 200[FONT=&]°[/FONT]F is sufficient enough to extract most of the cannabanoids from the herb when preparing canna-butter, whereas those temps are nearly half the temperatures required for "air extraction". How can I be sure to maximize the potency of my butter with temperature regulation? How do I know if & when THC would vape away from the butter or recipe? My concerns for losing THC in the air are minimal with this Peanut-Butter Canna-Bomb recipe, but I often wonder how much THC is lost when cooking brownies or anything over the vaping temperature of THC (300[FONT=&]°[/FONT]F). Theories & discussions are welcomed, but I'm really hoping to hear some actual proven facts as well as some experiential wisdom regarding this. Thanks!
