Which words are you missing?
Have you considered performing an e-search on them Mr?
presumably you grok “yellowish”. which would imply you understood “ish”
from there, one has to apply “ish” to “isolate” == kind of like “isolate”, but not quite, because there are clearly other things in there (because it’s yellow!!)
leading to the conclusion that you don’t understand what an anti-oxidant is?
have you considered looking it up?!? (Mr esearch)
or, just working with what you’ve got?!?
“anti” = opposite. “oxidant”, hmmm, probably has something to do with the oxidization folks are telling you about…
yes grasshopper, there are naturally occurring compounds in cannabis that prevent oxidation. by crystallizing a couple or three times, your source has purified the cannabinoids away from that oxidization preventing magic…so when you heat them up in the presence of oxygen, they oxidize.
you have two choices. remove the oxygen, or dont remove the antioxidants.

Does oxydation have something to do with temperature ?
it’s a chemical reaction. I’d go out on a limb and possit that ALL chemical reactions are affected by temp (eg aint nothing happening at 0oK).
perhaps as part of this “research” you’re doing you should take some basic chemistry…Finding Basic Knowledge
