A new survey by The Vegan Society found that 91 percent of vegans sometimes struggle to find 'grab and go' food options.
Although food options for vegans have dramatically improved over the last few years the research, which involved 2500 UK vegans, suggests there is still room for improvement.
This has prompted the society to launch its Vegan on the Go campaign.
According to The Vegan Society, veganism is growing at an exponential rate and is an untapped market that could offer huge opportunities for restaurant owners, investors and food developers.
According to Mintel's Global New Products Database, there has been a 185 percent increase in the number of vegan products launched in the UK between 2012 and 2016.
Vegan on the Go campaign aims to bring attention to the growing demand for vegan options and to highlight to businesses that veganism is a market trend which is here to stay.
Elena Orde, Communications Officer at The Vegan Society, said: "We’ve seen some fantastic strides forward in terms of new, affordable vegan products in supermarkets and restaurants, but we want to make it even easier for people to go vegan and stay vegan.
"Offering vegan food options makes clear commercial sense – businesses are opening the potential market up to not only half a million vegans in Britain, but also to a million more vegetarians, the huge number of meat and dairy reducers, the lactose intolerant, the health-conscious and others who simply enjoy vegan food from time to time.
"Sometimes all it takes is removing a pesky small amount of dairy or egg to create a lovely vegan dish, which can really widen food retailers’ appeal."
According to a Vegan Society spokesperson: "Attitudes towards veganism have changed dramatically over the last few years, indicating that veganism is now winning British hearts and minds in ever greater numbers.
"The Vegan Society's survey last month showed that half of Brits know a vegan, over a half (56 per cent) adopt vegan buying behaviours and a quarter (26 per cent) thought public sector food outlets should provide a vegan option by law.
"Chain restaurants like Zizzi, Wagamama, and Wetherspoons all have dedicated vegan menus while coffee shops Pret a Manger, Starbucks and Caffe Nero are offering more and more animal-free products.
"The Vegan Society is keen on hearing about good practice in the food and drink sector, and are happy to publicise any businesses who excel at providing great vegan food options."
