Animal-free dairy: Could this be the future of milk?

Dairy alternatives with real milk proteins but no use of cows are now becoming a reality. In the US you can now buy animal-free dairy ice cream, and around the world scientists and food technologists are aiming to create lab-cultured dairy products indistinguishable from the real thing. This is possible through precision fermentation, a process which uses genetically engineered microbes to grow the proteins in a bioreactor, which is how insulin and rennet are already produced. The proteins are then separated and used to create products like milk and cheese from scratch.

Companies creating precision fermentation-made dairy believe it could play an important part in reducing the environmental impact of traditional dairy production, and provide a much needed source of alternative protein. But as this new industry emerges it’s still not known how consumers will take to animal free dairy, and if it can scale up enough to make the products widely available and affordable to make an impact.

In this programme, Leyla Kazim visits a company in London creating an animal-free cheese, and asks if it can ever be the same as a traditionally-made product. And as this new industry grows – how far could it go in making dairy more sustainable?

The True Cost of Food

The price of food is rising alongside fuel, energy and other costs, and experts are warning that households face the biggest squeeze on disposable incomes for at least 30 years. On average the lowest income families spend twice as much on food and housing bills as the richest families, so increasing food price inflation will disproportionately affect families already struggling to get by, according to the Resolution Foundation.

As millions more people are on the brink of being pushed into food poverty, the food industry faces a turning point. The publication of a government white paper responding to the recommendations of The National Food Strategy is expected soon. The strategy’s assessment was dramatic – that Britain needs to change what it eats and how it produces food, in order to reverse the damage it does to our health and the environment.

In today’s programme Sheila Dillon is joined by three guests to discuss the true cost of our food, and some of the issues we face in reforming the system. In these extreme conditions we now live in, how can we provide everyone with a decent diet that will underpin the UK as a healthy nation? With Tim Benton, Research Director of the Environment and Society Programme at Chatham House and Professor of Population Ecology at the University of Leeds; Kathleen Kerridge, anti-food poverty campaigner and Chair of the Lived Experience Panel at The Food Foundation; and Professor Corinna Hawkes, Director of the Centre for Food Policy at City, University of London.
