A minor mystery concerning MCT

While making some tincture at home, I encountered a minor mystery.

Starting Materials:

100ml of MCT

https://www.walmart.com/ip/BetterBody-Foods-MCT-Oil-Concentrated-MCTs-500ml/348905332

Process:

~100ml of mct was poured into a clean borosilicate beaker and was in a conventional household oven at approx 121 C for 2 hours.

It was heated alongside isolate which was decarboxylating in a separate vessel in the same oven. This is likely irrelevant to whatever happened to my MCT

Expected Results:

I would pull out one fraction of medium chain triglycerides in as was placed in the oven

Actual Results: The MCT seems to have fractioned. I have one fraction which is easily 99% of the contents, and a few small “bubbles” of a second fraction which are at the bottom of the vessel.

The fractions did readily emulsify upon agitation, yielding a translucent mixture.

Before someone asks why I was frying my MCT in the oven, my thought is it would ease homogenization since I have nothing even as fancy as a magnetic stirring hotplate. This is being made for personal use so “homogenous” is good enough

after 2 hours in the oven?

If it wasnt a vacuum oven maybe. Unlikely but possible. Oil floats on water so water beads sinking makes sense. Could have also been trapped gasses accumulating but the surface tension is greater than its buoyancy.

Id guess the oven is not that precise and is overshooting to maintain temp as well as the location of the glasses in relation to the ovens temp probe. Idk if you got it that hot, but the mct you used is a blend of c8 & c10 mct and they do have different bp’s. If it actually was hot enough to start frying then maybe it’s the c8 and c10 separating.
