  • Method and apparatus for determining the salt content of snack foods
    Patent number: 5750883
    Abstract: A method and apparatus for determining the salt content of snack foods by X-ray radiation backscatter. The snack food is irradiated with low-energy X-ray radiation in the range of from about 4 keV to about 12 keV. A detector of backscatter radiation is placed above the snack food at a distance in the range of from about 2 inches up to about 8 inches. The detected X-ray backscatter radiation intensity from the snack food is found at an energy level above the kilo-electron volts range of chlorine X-rays. The detected X-ray backscatter radiation intensity is representative of the snack food salt content and can be used to adjust the amount of salt or seasoning containing salt being applied to snack foods in a continuous on-line process.
