Pine Mouth - Long Story Short: Stay Away from Chinese Pine Nuts

Pine Mouth - Long Story Short: Stay Away from Chinese Pine Nuts

Friday after we recorded the podcast, Dave made a pesto.  Yesterday (Sunday) I was tidying up the kitchen and went to put the pine nuts in the right cabinet.  Of course I popped some in my mouth and went about my business.  As I finished the beer I was drinking I noticed a distinct bitter flavor in the back of my mouth which I dismissed as some lingering aftertaste of the Abita Turbodog I had left over from the Superbowl.  By the time I went to bed it had gotten pervasive though the last Turbodog had been consumed four or five hours before.

Unfortunately today I am constantly tasting this bitter taste in the back of my mouth and tongue.  I complained about it to my better half earlier today and she asked if I had eaten any pine nuts.  It actually took me a few moments to realize I had snacked on them.  Turns out she had read on one of her food blogs about the phenomenon known as "pine mouth" that was being caused by certain pine nuts.  Sadly this effect would appear to persist for days and even weeks! Its onset may have been triggered by my snacking on the pine nuts and that effecting those I had eaten as pesto two days before, or the snacked pine nuts may have been coincidental

Here's a picture of the offending pine nuts:



If there was ever an argument against buying any "American" types of food from China, this is it. The closest thing to a scientific study of this (totally observational but observed by scientists self experimenting) is here, and a pretty good article about it is here.  Not much information out there (though what is has thousands of responses of people experiencing this) but one thing I can tell you is if this taste sticks around for a couple of weeks I'm going to be very unhappy.  Here's a quick synopsis of what I've found out:
1.  It would appear this is caused by Chinese pine nuts only.
2.  It is probably caused by the nuts being heated in transit (imagine containers full of them riding cargo ships across the ocean) and the heat altering certain triglycerides.
3.  This is not caused by contamination by heavy metals or pesticides.
4.  It seems onset is around two days after ingestion.
5.  The effects last from several days to over two weeks.
6.  It does not effect smell but wreaks havoc on your taste buds.

  1. Thank you for posting a picture of the brand of pine nuts. We have been following this for about two years. I have worked with American pine nuts for about 14 years and we are getting ready to launch a shelled pine nut product. I think the condition could be caused by picking immature cones. The price of pine nuts has gone through the roof and there is a lot of pressure on the pickers to produce.

  2. Thanks, Penny. While camping in the desert out west we harvested these seeds for dinner almost nightly, for salads and pesto. (There is no reason not to eat well when camping. Coolers that are left closed will stay cold for many days.) It would appear this affliction is a recent phenomenon and is probably a combination of early harvesting, extreme heat during shipping, and possibly a different strain of the trees. The one thing I know for sure it that pine mouth sucks. I've noticed on the third day that the taste is much stronger in the evening and seems to set in after the first thing I eat in the morning (coffee tastes fine until then). If I can't find American pine nuts like yours I will do without.
