data on how long of a cooking time is required for best extraction? please read!

[melodious fellow]

I've seen recipes that call for cooking ground buds in either fat or alcohol anywhere from 30 minutes to 24 hours.

I'm seriously hoping that it doesn't take anywhere near 24 hours to extract all of the good stuff into fat.

I usually put ground buds in coconut oil at 300 degrees F for about an hour. Is this enough time to extract everything?

I'm hoping to find some solid science on how long of cooking time is required

It is going to be heavily dependent upon your chosen solvent.

Thanks for the reply. I really hope more people reply and soon!!!

My chosen solvent is coconut oil.

I have heard that hot ethanol extractions only take a half hour or so. Cold ethanol extraction recipes usually call for leaving grass in the alcohol for days or weeks.

I am really just interested in cooking oils, butter, peanut butter, etc.

Hot solvent extractions of most any sort will be invariably faster than cold solvent extractions, the only exception I can see being supercritical solvent extractions.

I like the hemp oil bases personally, tastes more minty! And if you can manage to keep THC solved in glycerin, that stuff tastes like raisins when it's warmed up!

I'm desperately trying to find some data on how long the extraction takes when using butter, coconut oil, etc.


Does anyone know of a chart that shows time vs temperature for making cannabutter?

I want to know as well. What are the different methods of achieving great extraction in oil through pan heating, or double boiling, or oven heating?

[khyberkitsune]

You're not likely to find data on this, as such things will vary depending upon altitude/atmospheric pressure, quality of the solvent, and other stuff typically unaccountable for without strict laboratory testing conditions.

I know this isn't "exactly" what you're looking for, but I offer it up in case it helps...

hello. i know nothing about extraction for cooking. i suggest requesting from cannabis food purveyors, or as you put it- conducting scientific experimentation on your own, and compiling a chart with your air pressure, altitude, and quality strain. i am a total sucker when anyone asks please read, and am voting Ron Paul, so wanted to wish you well. 300* just seems excessive to me. i am thinking higher percentage loss in manufacture. i personally would avoid alcohol or ethanol- to not introduce free hydrocarbons with mutagenetic cancerous characteristics into the cook. i am probably wrong, and another arm will be handy. i just keep the food separate from my intake. i like spreading the flavors on my palate. i get the advantage of simultaneous munchie satisfaction; just like the pleasures that way. perhaps give a class at Berkeley a call, alike a business dude with a product to market, and get them to work on it. i am just a sucker for politeness. enjoy.

Thanks for the link StoneMeadow. Not sure where ya found it, but I'm hoping to find a lot more like it.

I have read that saturated fats like butter and coconut oil are more efficient than ethanol. Most people who casually make brownies use butter.

I have some of my own data to post. Anyone want to help me conduct a somewhat scientific study on this?

I always decarboyxlate my nugs before grinding them. I decarboxylate (THCA ---> THC) at 145 C (290 F) for 7 minutes. 25 minutes at 120 C (255 F) is probably the better choice in terms of taste, but I am impatient.

I always use coconut oil since it is the most saturated fat i can find. And it is healthier and less ethically-problematic than butter.

After I decarboxylate my nugs, I grind them to a fine powder and add it to the melted coconut oil in a glass bowl. I place the glass bowl in the oven. I have gotten good results baking the oil at 100 C (210 F) for 2 hours, stirring occasionally. I have also gotten good results using 150 C (300 F) for 45-60 minutes. I have also made firecrackers using 325 F for 25 minutes.

If taste is my priority, I always go with the 100 C for 2 hours, although I am not positive if this is enough time to extract all the goodies.

It is so difficult to control for quality of grass, personal tolerance, etc with these experiments.
