Tomorrow’s food packaging today: Xampla’s edible film arrives in kitchens

Marc Rodríguez Garcia, CTO at Xampla writes…

As a protein scientist, I’m more used to science labs and academic conferences than kitchens and consumer launches. But this week, the first of our products will be shipped to the paying public for the first time. It’s a cookable stock cube wrapper.

Recipe box company, Gousto, is including our product in its deliveries, as part of their package for making Indian Spiced Carrot & Lentil Soup. Where the consumer would previously have taken a stock cube from a plastic or foil wrapper, they will now drop the whole item – wrapping and all – into the soup.

This simple consumer experience is the result of 15 years of Cambridge-based research into the fundamental understanding of how proteins can be shaped into useful materials, such as transparent and flexible films.   The result is a completely unique single-use plastic alternative made from common food ingredients such as pea protein.

Following a full year of product development and formulation working closely with Gousto, Xampla’s edible and cookable films are the first plant protein film in the world to go to market. Their potential goes well beyond stock cubes to applications across the food and drink sector. It will mean brands can still give customers the benefits of plastic in protecting the shelf life of a product, without harming the environment.

With 855 billion plastic sachets thrown away each year – enough to wrap the entire surface of the earth – the need for a sustainable replacement could scarcely be more urgent. Most sachets cannot be economically recycled: they end up in landfill or polluting the soils and the seas. Our stock cube wrapping shows the possibility that – for example – the ubiquitous ketchup and mayonnaise sachet could soon become edible alongside its contents. And if consumers don’t cook or eat the sachets, they can simply put them in the food waste bin.

Consumers are increasingly making choices about what they buy based on the sustainability of a product or service. The majority want to reduce their plastic use, and single-use plastics in particular are increasingly unacceptable. In a recent survey, 65 percent of consumers said there aren’t enough plastic-free options on offer for the products they buy, despite trying to avoid plastic packaging where possible. Fully 86 percent try to avoid plastic packaging at least occasionally.

Our mission is to work with the big brands to help them meet this consumer demand. Xampla’s customer-led approach is all about understanding what potential clients need – both to keep their food products fresh and to mesh with existing manufacturing processes. 

We are lucky to benefit not just from cutting-edge science and research, but from a team of technical and commercial experts, many of whom have come from the industries Xampla is working with. Each product we develop goes through an in-depth trial and testing process, making sure we prioritise the client’s need and the end consumer’s needs in what we offer.

We refuse to compromise either on consumer experience or on the end of life of our product. Xampla’s packaging will always protect its contents as brands and consumers expect, but will always be made from completely natural or edible materials, which will safely break down if they reach the natural environment.

It has been a pleasure working on this product with Gousto, demonstrating the potential of this technology through stock cubes. The company is a fellow B-Corp, with sustainability at its heart: a recent study by environmental services company Foodsteps showed that dinners from Gousto already produce 23% less carbon emissions than equivalent meals from supermarket stores.  Gousto shares our values, and we can use our scientific excellence to help them to deliver their sustainability goals.   

COP26 is highlighting just how global the movement away from polluting industries is, and how all countries and industries are engaging in the largest trend of our generation – sustainability. Our launch this week is the first step for Xampla on the road to providing solutions in all sectors to the harm caused by single-use and microplastic.


Xampla CTO, Mark Rodriguez Garcia, has been invited to speak today at the Environmental Packaging Summit. Marc will address the audience on ‘Natural Alternatives to Single Use Plastic’. This will be supported by Head of Marketing and Communications, Katrina Curl, who has been invited to join a panel tomorrow to discuss how advances in packaging sustainability are communicated to the public. 



Our CEO Simon Hombersley was invited by British Private Equity & Venture Capital Association to contribute to the COP26 debate today. Xampla is being showcased in Glasgow as one of the businesses looking to use cutting edge technology to solve the environmental crisis. 

Xampla at the Science Museum for half term

The Science Museum has invited Xampla, creator of natural alternatives to single-use plastic, to be a key exhibitor in its “Future Explorers” activity this October half term.  

Showcasing its innovation in creating the world’s first plant protein material, Xampla will help children from the age of 7 to think about how the world will change by 2050.

As part of the week of action, Xampla will show young visitors to the museum how to identify microplastics and their harmful impact on the ocean through games and interactive demonstrations. 

Xampla’s team of experts will be on site in South Kensington to engage with families as part of the company’s continued efforts to boost STEM education for the next generation.

The product of more than 15 years’ research at Cambridge University, Xampla has developed a plant protein material that mimics the molecular structure of spider silk, creating a strong, flexible and entirely natural alternative to single-use plastic. Its technology has applications in flexible films used in packaging, microcapsules used to contain fragrances in household products and nutrients in food and drink.

The Science Museum partnership comes as Xampla prepares to commercialise its products for customers across a range of industries.

Xampla CEO, Simon Hombersley, said: “We are incredibly proud to be invited to partner with the Science Museum. At Xampla, our team of experts has a real passion for taking science out into the real world to educate the next generation about STEM careers.  We hope to inspire some of the children we meet this half term to be tomorrow’s scientists and innovators, seeking to improve the world around them.  

“The activity will be ‘hands on’ and will be about getting young people really excited about science and the impact a career in this field can have.  We will then be building on this programme of outreach over the next year with more events and activities to get involved with.”

Laura Southall, Head of Learning at the Science Museum, said: “We’re excited to be joined by Xampla to ignite the curiosity of young visitors this October half term as we explore the effects of and solutions to microplastics in our environment.”

The Future Explorers activities will be taking place at the Science Museum, London, between 25th-29th October. For more information visit: 


Xampla is delighted to be featured today as no 7 in The Times ‘Ones To Watch: Bright Ideas For A Bright Future’. James Hurley writes

“Thanks in part to BBC’s Blue Planet II, consumer awareness of the evils of single-use plastics has never been higher. The mission of Xampla, a Cambridge University spinout, is to replace everyday single-use plastics with its alternative based on plant protein. The company says the material, the first of its type to be commercialised, has the convenience of plastic but decomposes naturally and without harming the environment. It hopes to offer an alternative in ares such as packaging films and sachets as well as for microplastics used in cosmetics, agriculture and industrial products and the like. The material was inspired by the process a spider uses to create silk, and stems from a breakthrough by Professor Tuomas Knowles and Dr Marc Rodriguez Garcia, protein experts at Cambridge. In January the company secured £6.2 million in fresh funds from Horizons Ventures.”

Gousto trials world’s first edible packaging made from pea protein

Edible stock cube packaging created with University of Cambridge spinout, Xampla 

Gousto is trialling a world-first edible packaging solution, as part of its efforts to continue reducing plastic packaging in its recipe boxes. 

After 15 years of research and one year of development, the stock cube wrapper is the world’s first edible packaging to be made from pea protein. Created in partnership with Xampla, a mission based spinout from the University of Cambridge, the stock cube will be trialled in Gousto recipe boxes this month.

The edible packaging is made by engineering and drying a pea protein material into sheets that have the same benefits as plastic, being able to preserve the food’s flavour and shelf life, but with none of the packaging waste. What’s more, the material is also vegan and gluten free.

Home cooks who take part in the trial will enjoy the vegetable stock cube in Gousto’s Indian Spiced Carrot & Lentil Soup recipe, by simply dissolving the stock cube and its packaging in hot water.

Following its first full year of profitability in 2020, the recipe box company recently became a certified B Corporation™, joining a global community of businesses that are committed to growing the right way for people and the planet, including Xampla. 

This was achieved in part by Gousto’s ongoing work to reduce plastic packaging in their recipe boxes. Last year the business cut plastic by 50% in their boxes by switching to more cardboard packaging and launching the Eco Chill Box, an innovative insulator made of recycled cardboard, that keeps ingredients fresh in boxes. 

A further 17 tonnes of plastic could be saved by Gousto annually if the new edible stock cube packaging is rolled out in full to customers in the future.

The edible stock cube packaging is being trialed to replace Gousto’s existing stock mix sachets, for a packaging-free stock that’s full of flavour.

Gousto CEO and founder Timo Boldt said; “At Gousto, our purpose is to build products that have a positive impact on people and the planet and we invest in innovations that will help us get there. We are so proud of our Eco Chill Box and the significant amount of plastic we cut from our boxes as a result. This partnership with Xampla is another super exciting step towards reducing plastic packaging even further.”

We’re excited to see what our customers think, and to continue paving the way for innovative sustainable solutions in our industry.”

The new innovation comes after a recent study by environmental services company Foodsteps revealed that dinners from Gousto produce 23% less carbon emissions than equivalent meals from supermarket stores. If every home in the country replaced supermarket dinners with meals from Gousto for just one year, 10.3 million tonnes of CO2e could be saved, the same as taking nearly 140,000 buses off the road for a year.

Xampla CEO Simon Hombersley said; “This world-first edible pea protein packaging is the product of 15 years of University of Cambridge research, and over a year of development with the Gousto team. We’re so excited to be working with the recipe box company to offer more sustainable alternatives to plastic, and hope this marks the beginning of significant change within the industry and many more innovative packaging solutions in the future.” 

The edible packaging is available now for customers to choose to add to deliveries from 6th-12th November, as part of the Indian Spiced Carrot & Lentil Soup recipe.  

The future of fragrance: creating plant based, biodegradable fragrance microcapsules

By Lynette Holland, Principal Scientist

Over 20 years ago I began my product development career in the Fragrance and FMCG industries. In more than two decades I have witnessed – and worked on – my fair share of product innovations responsible for enhancing consumer experience.

Now having joined the team at Xampla, innovation has taken on a whole new meaning. Responding to impending regulation, we are working on solutions for industry that build on the ground-breaking plastic product developments of yesterday to substitute them with sustainable, plant-based alternatives that mean businesses do not need to compromise on the consumer experience their products provide.

Our plant protein material is the product of 15 years’ research at the University of Cambridge. It performs like conventional plastic but is fully biodegradable. Developed by an expert team with a background in industry, we are uncompromising in our regard for the consumer experience. Our material has applications across many single-use plastic products, and one of our core launch products will be our microcapsules.

Plastic fragrance microcapsules are set to be regulated under the ECHA microplastics ban which will prevent the release of 500,000 tonnes of microplastics over 20 years.  As they are too small to be collected at end of life they present a real environmental challenge that needs to be overcome. Yet, whilst necessary, this regulation puts the known-and-loved consumer experience of fresh scent bloom and longevity in our home and personal care products at risk.

This has driven fragrance microcapsules to be a pressing product application for the team at Xampla. After years of R&D our ground-breaking material is uniquely able to encapsulate fragrance, without needing to use any hazardous chemicals to create the shell to protect the fragrance. There is no chemical cross-linking which means our material is biodegradable.  

Not only is this a breakthrough for the planet, it will also help to futureproof brands against further regulatory changes surrounding microplastics. This means that consumers can continue to enjoy the same fragrance experience they are used to without a change in performance. What’s more, Xampla’s fragrance microcapsules are designed to fit with existing encapsulation processes, minimising adverse impacts on the supply chain.

Far from being a one-size fits all approach, we tailor our products to our customer in order to support brands in evolving their product line for a sustainable future. Our fragrance microcapsules will be launching soon, but in the meantime, you can find out more and discuss your development needs by contacting
