Mushrooms in VN sun-dried or not?

If they're produced in Vietnam, they're sun-dried.  Sun drying is cheaper.

So, the next question would be....what is the place of origin?

Mostly China, then Thailand and Vietnam equally.  There are mushrooms from Japan and Korea but they're not sold at wholesale markets and they're very expensive.

1/ I wouldn't buy dried mushrooms from those 20kg bags. The price is low but there's no stamp indicating the place of origin. 

2/ I wouldn't hope to find sun-dried mushrooms from wholesale markets.  Anything sold in bulk would not be produced by natural methods because drying mushrooms under the sun or over wood/charcoal produces only small quantities.

3/ Heat pump dryers are not expensive.  At 50M, a HPD can yield 20 kg at a time of dried mushrooms, veggies, fruits, herbs for traditional medicine, seafood, etc. in a fraction of the time and energy of a drying oven.  Thus, if you don't want to pay for imported sun-dried mushroom, it'd be best to buy HPD mushrooms from legit shops instead of the stuff at Bình Tây and An Đông Markets.

Thanks, Ciambella and Colinoscapee. So, like with organics, the only way to be sure is to grow and dry them yourself. Wish I lived someplace where I could do that.

I think fresh Shiitakes taste vastly better than dried, but am intrigued by the Vitamin D angle.
