Episode 6: Thymeless: Flavours, aromas and their chemicals causes with Professor Jane Parker (University of Reading)Whether you’re a sweet or savoury kind of person, or prefer something in between, we all have difference preferences when it comes to taste and smell. For example, why is it that some of us can’t get enough of the smell of petrol, but others despise it? We know that there are five basic tastes, but what’s the link between smell and taste? What makes different smells unique? This week we speak to Professor Jane Parker, researcher at the University of Reading, about flavours, aromas and the chemicals that cause them.TimestampsIntro [00:00]Meet the hosts [01:58]Chemistry of flavours background [03:20]About the episode [06:31]Meet the guests [07:55]Interview [11:30]The Breakdown: [37:21]The Expert Test [39:04]Conclusion [41:45]Meet our guestProfessor Jane ParkerJane is Professor of Flavour Chemistry in the Department of Food and Nutritional Sciences at the University of Reading, the Food Research Group Lead and founder of the Flavour Centre which provides consultancy, training and technical service to industry (>100 food companies).
