Food Allergen Detector

This invention would allow somebody with allergy problems to eat out without requesting a allergen menu or risking eating something they shouldn't. I got this Idea because I am allergic to casein, a protein in milk, and it is very hard to eat at restaurants or friend's houses because of a possible reaction. For some people, this is a life threatening problem and not just a minor annoyance. My solution to this problem is to detect allergens in food. The detector would have buttons on the front that would be used to select the allergen to be tested, and the amount would be displayed on a digital scale. The test results would be displayed as: -A very small amount in the air -None in the food sample -Traces in the food samples -Don’t eat this (large amounts) The machine, which is about the side of a cell phone, would be easy to use and carry. Food samples that you wanted to test would be placed in a small vial would attach to the side. If readings where having problems, the machine could be reset by testing a pure sample and an empty container.

How Math & Science Can Help Power My Idea

This machine would detect allergens by the proteins in them, which is the part that most people are allergic to. The sample would be dissolved using a weak acid to make it translucent, and/or placed in water. Then an ultraviolet light would shine from the top of the container. Sensors on the side of the vial could detect allergens from the light and display how much there is on an LCD screen.


  • Ben Kaufman First of all, great sketch/ rendering- Second, you have really hit on a HUGE problem (which usually is step one in making a great product). The science is there, and the market is waiting. LOVE. March 25, 2012
  • Mark Payne Wow, a big need here if we can find a way to make it work!!!!! March 04, 2012

    waitdonteatthat We can empathize, as our son has dairy, egg, peanut, and tree nut allergies. Eating out is not an option for him. WIth the increase in food allergies, this product is definitely needed! April 01, 2012
  • PNUTECH More improvements: The sample tube would be on the inside with a protective layer to prevent radiation leakage from X-rays and the sensors would need to go all the way around to get accurate readings. March 30, 2012
  • Goldenchest This idea seriously needs more votes. I could see it saving many lives, and the fact it'll be portable and more accessible to the general public makes it awesome. You got my vote. March 30, 2012
  • Kate Yager Awesome idea!!! March 27, 2012
  • PNUTECH a crystal structure stored in the device's memory, the scale would light up red and display which allergens were detected. If you want to know more go to the Pnumenu Robotics website. March 10, 2012
  • PNUTECH the top of the container. The radiation refraction would then be measured using a method called X-ray crystallography to determine what proteins are in the sample. Then, if a protein matched... March 10, 2012
  • PNUTECH More on how it would work: A capacitor and two transformers would convert energy from normal batteries to a very high voltage, which would be channeled through an X-ray tube (NOT ultraviolet)... March 10, 2012
