    Thank you all for taking a look at this long-standing concern. To put things in context, what are the common strainer sizes currently used in commercial establishments?

      That is a really good question! Right now, most restaurants use a filter separate of their fryers to filter their oil. The filter material pore sizes that they use are actually smaller than anything we tested. That being said, our concern was mostly with the difficult process that needed to be completed in order to properly clean the oil in commercial restaurants. From our research, we found it was a very extensive procedure that required people to walk around a wall in the kitchen to filter the oil. We were skeptical of how well the procedure was being done every single time the oil needed to be filtered, considering the inefficiency and difficulty. We drew a conclusion that even though the filter pore size they use is very small, the way through which they filter the oil may not be as safe as it sounds. Also, restaurants only clean their oil after it gets visibly dirty or after 2/3 days. This doesn’t allow them to make any gluten free orders in between cleanings. We are working on making a possible new procedure for restaurants to use that is more efficient for the establishment and also allows people who can’t eat gluten to order safe food.

    This project is excellent!! How wonderful to see that students can use their school projects to address something they care about. And what a great idea! I hope this can lead to some change in restaurant procedures down the road some day. Thank you for your great work!

    Thank you for doing this research! A local restaurant uses separate fryers for fries and gluten contain items, but run them through the same filtration system. I assumed that it was being contaminated in the filtration system, but it sounds like it could potentially be safe. I may have to ask more questions rather than writing it off completely.
