Patent number: 11243190Abstract: A photo acoustic non-destructive measurement apparatus and method for quantitatively measuring texture of a liquid. The apparatus includes a laser generating tool, an acoustic capturing device, and a data processing unit. The laser generating tool directs a laser towards a surface of a liquid contained in a container and creates pressure waves that propagate through the air and produce an acoustic signal. The acoustic capturing device records and forwards the signal to a data processing unit. The data processing unit further comprises a digital signal processing module that processes the received acoustic signal. A statistical processing module further filters the acoustic signal from the data processing unit and generates a quantitative acoustic model for texture attributes such as hardness and fracturability. The quantitative model is correlated with a qualitative texture measurement from a descriptive expert panel. Textures of liquids are quantitatively measured with the quantitative acoustic model.Type: GrantFiled: December 5, 2019Date of Patent: February 8, 2022Assignee: Frito-Lay North America, Inc.Inventors: Ou Bai, Wilfred Marcellien Bourg, Jr., Scott Fagan, Enrique Michel-Sanchez, Shahmeer Ali Mirza, Scott G.

Patent number: 10070661Abstract: A feedback and feedforward as well as a statistical predictive control system and method for continuously controlling texture of a food snack in a manufacturing process. The feedback system includes a quantitative texture measuring tool that is positioned downstream of a food processing unit. The texture measuring tool continuously measures a texture attribute of food snack from the food processing unit and feeds back texture attribute information to a controller that controls input parameters to food processing unit such that the texture attribute of a resultant food snack falls within an acceptable limit. The texture measuring tool comprises an excitation tool that strikes the food snack and produces an acoustic signal that is processed by a data processing unit. The data processing unit identifies relevant frequencies in the acoustic signal and quantitatively measures a texture attribute based on a correlated model that includes the relevant frequencies.Type: GrantFiled: September 24, 2015Date of Patent: September 11, 2018Assignee: FRITO-LAY NORTH AMERICA, INC.Inventors: Ou Bai, Wilfred Marcellien Bourg, Jr., Scott Fagan, Enrique Michel-Sanchez, Shahmeer Ali Mirza, Scott G.

Patent number: 9678015Abstract: A method and apparatus for analyzing one or more elements of targeted moving snack food surfaces uses laser-induced breakdown spectroscopy to detect the presence, absence, or amount of an element on a heterogeneous surface, including seasoned and ready-to-eat snack foods. A laser is used to quantify the element concentration without destroying the targeted sample. An automated on-line system may be integrated into the method to create a closed-loop feedback control system, adjusting the concentration as desired.Type: GrantFiled: September 25, 2015Date of Patent: June 13, 2017Assignees: Frito-Lay North America, Inc., Applied Spectra, Inc.Inventors: Scott Fagan, Paul Allan Martin, Scotty G.
