Does anyone think it's a bad idea to order an olive oil product during the hottest weeks of the summer? I'm thinking it might be better to wait until September at least.
Olive oil can sit out no problem. It is not normally refrigerated.
Just because people use olive oil in a certain way doesn't mean that this is "no problem". As the Olive Oil Times pointed out, many have become used to degraded oil--“The sad truth is that most people in the US… are accustomed to the flavor of rancid olive oil.” But here we are not interested in the taste of the oil, only its usefulness in a longevity supplement. And since we have no way of knowing how fast the combination degrades, best to use it up rapidly and keep any excess frozen, where it can be expected to last some 16 times longer than at room temperature.
It takes at least a year after opening for Olive Oil to go rancid.
And I call BS on the "accustomed to the flavor of rancid oil". I have eaten oil while in Europe and Oil in the US, and bought oil sourced from or bottled in Europe, Australia, Africa (Morroco, Tunisia), and California.
I have yet to notice a discernible difference other than the varietal of olives, and type of oil (EVOO, vs VO, vs processed). So either EVERY bit of Olive Oil I have eaten has been rancid, or the article is F-O-S and is a trade organization's efforts to increase consumption.
I have noticed a change in the odor of home brewed C60/EVOO kept on the shelf, and this seems to occur at about 3 months, so now I throw it out before that point, and I keep most of it in the freezer. The rule of thumb is that chemical reactions occur twice as fast for each 10 degree C increase in temp, thus decreasing it 40C--from room temp to freezer temp--should decrease the rate of oxidation by roughly 2^4 = 16 times.
The adducts picked up by C60 can oxidize, as can the C60 itself, and we don't know what effects that will have, or even if a partially oxidized product will degrade the expected results. Certainly the one trial done here with old C60 oil obtained from the original Baati researchers didn't work out as hoped. Without controls, it was impossible to know if the rats lived longer, but they all got cancer, which is worse than the normal rate.
Caveman doctor says this--
The structure of fats also affects their shelf life. Because polyunsaturated fats are less stable, they tend to break down into oxidized products not just in the pan, but also on the shelf. When exposed to light, oxygen, and even non-cooking temperatures they get oxidized.
The converse to this is coconut oil, primarily a saturated fat. It is solid at room temperature due to its stability, and its shelf life is very long, coming in at around 2 years. However, vegetable oils and polyunsaturated oils spoil after only several months and become rancid. Even olive oil, a monounsaturated non-vegetable oil, goes rancid after about 6 months.
