First off, let me make you aware of the potential bad health effects of consuming too much maltodextrin. It is in many processed foods and it's bad health effects are debatable. It is safe and effective if used as directed. And, in the amounts we are talking, it's barely a consideration. But, I wanted to note it so you can look it up and decide for yourself. I am a total health nut, good food eater and gym rat. I'm almost 70 and I am not afraid of maltodextrin. If you are diabetic, this stuff is very high on the glycemic index. Do a quick search of "Is Maltodextrin Safe" and you'll get both sides.
OK, with that said... TAPIOCA Maltodextrin is what I recommend. I have tried other types but I find the tapioca to be the fluffiest. It can be made from corn, potatoes, rice or wheat. Like I said, I like the tapioca based.
Are we allowed to post Amazon links for examples? I'll check and edit as required.
As for the cannabis oil, there are a number of variables. I get mine from pressing rosin. I don't do solvents but I suppose you can do this with wax, shatter, BHO, whatever. As long as it will mix with coconut oil, you should be OK to go. YMMV
I have mixed straight rosin with the maltodextrin but the rosin is very difficult to work with because of the extremely high viscosity. Generally, it is best to infuse it with some coconut (or whatever) oil before mixing it with the maltodextrin. Plus, it will allow you to dose the oil much more accurately. I have tolerance issues and my low dose is 400 to 600 mg. I get a little buzz on a gram. It kind of sucks. On a side note, this is why I am trying shrooms. The doses I require in cannabis are simply too high. OK, let's move on.
First, you need to decarboxylate the rosin. I use small glass lab beakers and they allow me to work in small quantities of a gram or 2. Simply place the rosin in a glass beaker and place it in the over at 240F for 40 minutes. I also do this on a hot plate but make sure you keep the plate temps below 300F or you'll start vaping off the THC. You can watch it as the THCa drops off the CO2 to convert to THC/9. The larger bubbles are the CO2. When the smaller bubbles are almost done, you're probably decarb'd. You can watch this happen in your oven. Sometimes it only takes 30 minutes instead of 40. Depends on variables like quantity, your oven, the glass container, etc etc. You'll see it when it's done.
Through experimentation, you'll find the sweet spot. Not enough and the buzz is not great. Too much and the buzz is sleepy time. Again, YMMV
OK, we have decarb'd rosin and now we infuse it with oil. I like coconut because (and, I'm not 100% sure on this) but I think it's one of the few oils that does not need bile to carry the THC. This needs verified. I mix the oil with the rosin in the glass beaker and put it in the oven (or hotplate) and run about 170F for 15 minutes or so, stirring every 5 minutes or so
I use 50/50 oil and rosin because of my tolerance issues but most will probably be using a 4:1 or 5:1 to dilute the rosin as needed.
OK, now we have oil infused rosin and maltodextrin. I mix 1:1 by weight. The maltodextrin weighs next to nothing so a gram is a lot. Some of the recipes I saw go for 4:5 oil to maltodextrin. Some went as high as 1:10.
Place the maltodextrin in a (I like glass) mixing bowl and pour in the infused oil. I like to use a whisk but some people use a fork. You'll be amazed at how the maltodextrin encapsulates the oil so evenly.
After the 2 are well mixed, press it through a fine strainer. This makes sure there are no clumps or oil that has not been covered. After this, you have a very 'smooth' powder.
Just a note on maltodextrin. And, we need, once again, to verify me on this. The maltodextrin actually encapsulates the oil at the molecular level and 'hides' the fact that it is oil from out body. Making it think it is water soluble when, indeed, it is still oil. I'll verify this and edit as needed.
OK, so now we have cannabis oil infused maltodextrin. Divide it into doses as needed and try to experiment. I tried to mix it with cold beer and it didn't work well at all. Hot tea was perfect. If you can get your dose, simply put it under your tongue and let it melt. Because our body thinks it is water soluble, it will be absorbed into the blood vessels in your mouth and onset should only be 10 minutes or so.
I use this infused maltodextrin to make home brew beer.
I put the maltodextrin in the water after the first boil. Just before I add the Malt Extract. However, I plan to experiment with adding it after the malt extract to see if the existing sugar would make any difference. The beer I made turned out awesome. There was ABSOLUTELY NO TASTE of cannabis. I gag when I taste most cannabis edibles. Somehow the taste and smell make me want to puke. So, I mostly do caps. However, this maltodextrin routine makes the cannabis oil almost completely tasteless and odorless so I am very thrilled about that aspect.
I also made hard apple cider using cannabis caramels as the sugar. But, that's another thread. :)
This turned out to be quite a rant. Sorry it's so long. Even at it's length, I left out a ton of detail. Cannabis is and has been my hobby for many decades. I will be more than happy to provide details or answer questions. I'll see if I can dig up some old pictures and edit them in here.
Thanks again and hope this helps someone.
Here is an interesting patent from our old friend Ed Rosenthal.. https://patents.goog...2016135621A1/en
Pics... Here are some pics of the oil mixing with the maltodextrin. First is the oil poured into the maltodextrin. Second is after whisking it together and the third is after sifting.
