Ep. 216. Sandro Tarchini: Driving Global Food Traceability, Authenticity with Blockchain

Jenny Du, Ph.D. is Co-Founder of Apeel Sciences, a post-harvest intelligence and solutions company helping suppliers and retailers deliver fresh, healthier, and simply better produce at scale—using plant-based materials science to close the gap between what consumers expect from fresh produce and what the supply chain is able to deliver. Jenny earned her bachelor's degree in engineering chemistry and her Ph.D. in chemistry from Queen's University in Ontario, Canada, where she was awarded an Alexander Graham Bell Canada Graduate Scholarship. She then joined the University of California, Santa Barbara as a postdoctoral researcher in chemistry, where she met co-founders James Rogers and Lou Perez. In 2013, the three founded Apeel in a garage in Goleta, California. Today, Apeel has earned regulatory clearances and operates in several markets worldwide, including in the U.S. and in Europe. Jenny was named to Inc.'s 2021 Top Female Founders 100 list and named one of TED's Top 10 most-watched speakers of the year following her 2025 talk, "The Science of Making Fruits and Veggies Last Longer." In this episode of Food Safety Matters, we speak with Jenny [1:51] about: Her journey from being a postdoctoral chemistry researcher to co-founding Apeel Sciences The science behind Apeel's clean, edible produce coating and how it differs from traditional products applied to produce post-harvest Apeel's evaluation and approvals by FDA, EFSA, and regulators in more than 40 countries How Apeel disrupts the existing $11 billion dollar post-harvest industry and what happens to produce between the field and retail The implications of Apeel on food safety standards and protocols for post-harvest treatment and microbial control Apeel's response to industry resistance and disinformation The broader consumer movement demanding transparency about food production and ingredients, and where Apeel fits into this conversation.

Kye Luker serves as the Chief Product Officer at FlexXray, where he leads development of the company's innovative X-ray inspection process and technology. With more than two decades of experience in the service, consumer packaged goods (CPG), and food and beverage industries, Kye brings a wealth of knowledge in continuous improvement, quality assurance, and formulations to his role. In this episode of Food Safety Matters, we speak with Kye [1:34] about: How foreign material (FM) contamination continues to challenge food manufacturers as it remains one of the leading causes of food recalls each year Why certain contaminants are difficult to detect with traditional metal detectors and inline X-ray systems How many FM control strategies remain reactive, with detection systems acting primarily as signaling devices rather than preventing contamination upstream The role of third-party inspection partners in helping manufacturers investigate FM incidents, narrow hold windows, and support data-driven product release decisions Key limitations of re-inspecting product in-house using the same inline equipment, speeds, and sensitivity settings that originally failed to detect FM How computed tomography (CT) inspection can analyze products in three dimensions, allowing inspectors to identify FM hidden by layering effects in complex food products The benefits of a multi-pronged FM control strategy that combines upstream detection technologies with advanced downstream inspection Advanced technologies utilized by FlexXray to enhance detection sensitivity and precision, including photon-counting X-ray systems and machine learning algorithms.
