This is the big brain experiment type stuff you just don't see on other sites and one of the reasons why I love this community and website.

When drying at room temperature it would be beneficial to monitor/report your relative humidity levels as that will greatly affect how dry the mushrooms can get without artificially raising the temp. You can usually find thermometers with relative humidity readouts that are inexpensive.

The whole purpose of raising temperature when drying is to lower relative humidity which allows more moisture to evaporate. Ergo, those in humid climates, like Pacific Northwest, etc., will have different results air drying than those in more arid climates or even those drying at a different times of the year.

Good point. I think that I mentioned in the first update on the OP that my rh is low here which is likely to have an impact on results.

Quote:
So I stick to my recommendation to always heat dry for best potency preservation in storage. If you plan to use them right away forced ambient air may improve the final potency by as much as 10%. Keep in mind that my ambient test was with a relative humidity below 20% so your mileage may vary in a more humid environment. Insufficiently dry mushrooms can lose far more than 10% potency in a few days, weeks or months. Fully dried mushrooms easily hold their potency for years.


I worried that comparing the unheated and heated drying would not show much in the way of difference due to the very low humidity here. However, even with rh below 20% there was still a significant difference in weight from water. I can only assume that the difference would be even greater in a more humid or very humid locations without the addition of heat in the drying process.

I have a couple of fat GTs about fully mature. I plan to try to squeeze in the heated vs unheated drying potency after storage test with them. If not this time, I will have to start another run of GTs as these shoeboxes are about tapped out.

I was thinking about this post in the context of mushroom size, while drying quite small shrooms from a cake. It doesn’t seem immediately clear to me that the 24h time would apply always, irregardless of the size and thickness of mushrooms.

Quote:
Keep in mind that each sample was very small and each piece was sliced into vertical quarters. I believe that contributed to the short times required to reach stable weights. For larger batches with unsliced mushrooms the drying time would likely be much greater.


You do sort of address it here, but maybe it’s something to explore further. Either as a function of thickness vs time or to find out what would be the optimal size to cut the material that’s being dried.

Not that it actually matters that much to me, but sounded interesting in my head.

For sure. My pans are definitely dry long before the 24 hour mark, but as the latest results show, there is no harm in letting them run longer at full heat no matter the size. Once all of the water is gone potency loss is not a continuing danger.

The ambient drying weight had stabilized in my 20% rh test but lost an additional 7% of water weight when that sample was subjected to heated dehydration.

So my conclusion is that unheated drying does not remove all water. And that over drying does not cause additional potency loss. Therefore, heated drying for a longer time is the safest way to ensure that potency is protected. You may be able to get them fully dry in less time, but there is no harm in drying for longer to be absolutely sure that they are dry. And, stable weight is not bullet proof evidence that all water has been removed.

Ahaa, right you are! I now noticed that update where you tested that. Must have been my compromised reading comprehension after few glasses of wine too many. :laugh:

Excellent test as usual rev.  Exactly what ive always suspected and what all the old heads--namely pasty--have always said. 

Negligible. Less than 3%


I probably dump more than 5% of any given tub just for being ugly. 

I especially liked the part when Dave Bennet came to poke holes in the data and ate crow instead.  bout time.  15%... pshhhh. Totally just shooting from the hip, as usual.


good stuff. Great job all round rev, as usual. an asset to the community.  Thanks for everything.

The actual difference is not only 3%.

The OP had made an update where he says that the low temperature ones have 7% more water than the heated dried ones.

What this means is that the low temperature dried ones have the potency diluted by the gram.

So what we need is to do the math to actually find the difference, and equalize it.

The 25C sample had at first 11.06g. After further heated dehydration, it had decreased to 10.34.

So you need to do 11.06/10.34. What results in 1.06963 difference.

Now we need to use this number to find the difference in both.

The room temperature sample had 16.21 mg/g.

The 35C sample had 16.28 mg/g.

After multiplying both by the number 1.06963, we find these results:

The room temperature sample now have 17.34 mg/g.

The 35C sample now have 17.41 mg/g.

Now, when we compare it by percentage we find a 10.1% difference in the 35C sample and 9.7% of difference in the room temperature sample, compared to the 71C sample.

The OP said he was willing to defend a 10% difference from any side. There is a 10% difference or very close to that in both low temperature samples.

Now what actually matters is a long term stability test, that the OP already had proposed to do, and I'm very excited in seeing the results.

In my opinion, we should also not extrapolate or make solid conclusions before testing more variables.

It is very obvious that there are some flaws in the methodology. For example, why the air fryer 85C sample had so much more loss than the 71C one? This is an unanswered question until now.

The OP should be measuring the temperature the actual mushroom is reaching, instead of just the nominal temperature of the dehydrator/air fryer he is using, for control purposes. This could be what is making the difference between the air fryer one and the dehydrator one, maybe the nominal temperature is different to the actual heat reaching the mushroom.

The other obvious flaw I've seen is that when using a drying chamber, it is better to use a glass, airtight container. He is using a plastic, not airtight one, which could reduce the potential of the desiccant. The normal desiccant used is also silica instead of DampRid, which could affect results.

The result he got after putting the mushroom in the dehydrator for 72 hours goes directly against the results all of the scientific papers we have until now, and he says that in other updates. And these scientific papers generally follows a better methodology and have better equipment.

But don't be hasty, I'm not saying the test the OP made is useless or wrong, just reinforcing that we maybe need more data before making hard statements.

Either way, I think waiting is the best for now. The stability test should answer some of these questions, and then he could be planning testing other possibilities after that if he wants.

@Rev: Can I make a suggestion for a future experiment?

I'm curious how much magic is lost by leaving wet fruits out for a period of time without dehydrating them.

I have a small dehydrator so sometimes my fruits will sit wet in an open tub at room temperature for a day or two.

I also got lazy once and forgot some dehydrated fruit in a bowl for over a month. When I ate them they still had plenty of magic left.

Both tests could easily be done with your current testing methodology.
