Physics of food – the November 2016 issue of Physics World is now out


By Matin Durrani

If you love crisps – and frankly who doesn’t? – you’ll relish the cover feature of the latest issue of Physics World, in which features editor Louise Mayor tours the world’s biggest crisp factory at Leicester in the UK to see how physics is improving production of this yummy salty snack. The issue is now live in the Physics World app for mobile and desktop and will also be made available on later this month.

Elsewhere in this special issue on physics and food, you can find out how electric fields could help to cut the fact from chocolate and discover why sound holds the key to our appreciation of what we eat.

You can also see how physicists – being masters of data-gathering, modelling and simulation – are ideally placed to develop products that are healthier, more nutritious and make more of our resources. Find out too how soft-matter physicists are crafting “functional” foods that promote feelings of fullness and satisfaction.

If you’re a member of the Institute of Physics (IOP), you can now enjoy immediate access to the new issue with the digital edition of the magazine in your web browser or on any iOS or Android mobile device (just download the Physics World app from the App Store or Google Play). If you’re not yet in the IOP, you can join as an IOPimember for just £15, €20 or $25 a year to get full access to Physics World digital.
