Last year was not a year of hyped-up headlines for alternative proteins. Perhaps that is precisely why it was an important year for food biotech, the biotechnology behind everyday foods and ingredients. While the sector worked through a difficult funding environment, approvals were still granted, pilot lines set up and new platforms tested in the background. In short: headlines are turning into infrastructure. Frederieke Reiners heads GEA’s New Food business. She and her team work at the intersection of biotechnology and industrial food production. In this interview, she takes us on a world tour of food biotech in seven questions.
