Jarvis Stobbs: Edible synchtrotron science: cheese, chocolate and meat

Given as part of PALSA 2023 in Ithaca, NY, this talk describes the search for plant-based alternatives to meat, cheese, how to decrease the energy cost of chocolate production, and critical uses of synchrotron radiation in these efforts.

Speaker: Jarvis Stobbs, PhD - Strategic Support Group Lead, Canadian Light Source (https://www.lightsource.ca/about/cont...) On behalf of Alejandro Marangoni, Professor and Chair, Department of Food, Health and Aging, University of Guelph (https://www.uoguelph.ca/foodscience/p...) Date: July 13, 2023 Event: Invited Presentation for PALSA 2023 (https://palsa.chess.cornell.edu/) Location: Ithaca, NY Chapters: 00:00 - Introduction: Meat, Cheese and greenhouse gas emission 01:35 - Existing plant-based alternatives to meats are limited to "aggregates" -- like ground beef 02:45 - Whole-muscle plant-based alternatives use high temperature, high pressure and/or shear, which affects protein structure and can harm properties as food 03:19 - Example 1: a better plant-based alternative to meat, with already-existing proteins 04:20 - Use of synchrotron-based FTIR-microspectroscopy to understand a preliminary success - to image distribution of starches and protein 05:20 - Use of synchrotron-based computed tomography (3D scanning) to further understand distribution. 05:55 - Example 2: Plant-based alternatives to cheese 06:50 - Viable cheese alternatives should melt and stretch! 08:55 - FTIR-microspectroscopy & CT to understand underlying shape and distribution of fat, protein, and starch in cheese alternatives. 10:25 - Example 3 - Chocolate! Can chocolate tempering use less energy? 11:40 - The Tempering process - how it's done and the link between its crystalline structure and properties - see subsequently published article: https://doi.org/10.1021/acs.cgd.3c01130 23:32- Take Aways 24:36 - Acknowledgements PALSA stands for the Partnership for Advancing Light Sources for Agriculture. Originally founded in 2019, PALSA hosts bi-annual conferences to help leverage the power of synchrotron radiation to address world-wide challenges facing agriculture science.
