  • Devices and methods for the rapid, reliable detection and determination of acrylamide concentration in food substances and prevention of acrylamide formation in the same
    Patent number: 8129133
    Abstract: A device and associated analytical method to use for the sensitive detection and accurate, rapid determination of acrylamide in food substances is presented. Also described is the use of a kit device and associated analytical method in which a user can quickly and easily ascertain the amount of acrylamide in food substances with ease and in any location, including a non-laboratory environment. Such detection device and method may be comprised of a sample collection area on which a sample of food, after being mixed in a solution, is placed for example on the substrate of a biochip that includes an enzyme that along with a co-enzyme or catalyst, facilitates the conversion of either acrylamide to acrylonitrile or the conversion of acrylamide to ammonia.
