Please note, the following only applies to the gluten free chips made by these companies. Some companies make both gluten free and regular chips, both.
- Boulder Canyon chips - gluten-free line, but not a gluten-free facility. Every batch is sent out for testing, but I'm still waiting to hear the ppm of the test. Assuming 20ppm.
- Frito Lay's chips - Lay's staxx is the only chip of theirs made on a gluten-free line. It is tested for gluten at periodic intervals, must be <20ppm.
- Food Should Taste Good chips - certified by the GFCO, so <10ppm
- Garden of Eatin' chips - some made without gluten ingredients, but not tested for gluten and not made on a dedicated gluten-free line. Hain Celestial, the parent company, does not consider them one of their gluten-free products.
- Kettle Brand potato chips - gluten-free facility, every batch tested to <20ppm. Also, all their flavors have to have tested to <10ppm, if from other suppliers.
- Late July Organic chips - GFCO certified, so <10ppm
- Lundberg chips - gluten-free facility, periodic testing, <20ppm gluten. The gal recommended that if anyone reacted to less than 20ppm, they might wish to stick with the plain rice, but not the rice cakes or chips. The rice itself is processed in a separate facility with only rice and no added ingredients.
Re: GFCO certified foods. The reason I don't have a lot of information on these other than ppm is because information like testing frequency differs based on risk assessment. Where they get their ingredients, whether they have a gluten-free facility or not, and so on, all affect their process and testing procedures, and is often pretty much a pain in the butt to get. So I stop at GFCO certified and hope that'll be enough. :-)
I'm still waiting on some information for Mission chips. The only thing I can say for sure is that when I asked about all their corn products and gluten free lines, they said that their corn tortillas were made on a gluten free line, and they didn't comment on any other product. I'm assuming that means the tortilla chips are NOT made on a gluten free line, sadly.
