Raw Edge, a finalist in the Ajujaht competition, produces a probiotic, low-calorie drink fermented with lactic acid bacteria from natural juice; the juice is free from caffeine, artificial additives, and added sugar. Kristel Vene, co-founder of the company, holds a PhD in Department of Materials and Environmental Technology from TalTech and is a senior lecturer at the Department of Chemistry and Biotechnology.

‘Our beverages contain a clinically tested probiotic bacteria that supports the microflora in the stomach, thereby improving well-being, health, and athletic performance. Three different flavours are currently available: blackcurrant, dragon fruit, and pineapple,’ Kristel explained the benefits and advantages of the drink. ‘We plan to continue the research and development work in cooperation with TalTech.’
According to Kristel Vene, carrot juice fermentation has opened up a whole new field of research for food scientists: ‘Like with wine, which has been studied at the molecular level for decades, the influence of variety, soil, and bacteria on both taste and quality is important in carrot juice fermentation as well. However, it has not been studied in detail so far,’ the researcher says.

Kristel pointed out that sustainability is important, which is why the drink is always local, wherever it is sold. ‘We plan to expand rapidly, not by producing in Estonia and shipping jars across the globe, but in a sustainable way, by licensing the brand, technology, and production expertise to local vegetable growers who benefit from the opportunity to refine their raw material through innovation.’ According to Kristel, the sales and consumption of fermented products in Europe are on a strong growth trend. ‘The next market is most likely to be the UK, where we already have interested producers,’ she added.
However, Raw Edge is by no means the only TalTech-related team in the top three of the Ajujaht competition. The top three also features KIUD Packaging, whose founder and CEO Kaie Kaas-Ojavere holds a Master’s Degree from the MBA programme of TalTech, and technology manager Liis Tiisvelt holds a Master’s Degree in wood plastics and textile technology from TalTech. KIUD produces packaging material from durable and recycled textile waste, replacing the packaging industry’s single-use corrugated cardboard and veneer.
Caroline Aruoja, Head of the Startup Centre of TalTech, recommends that other innovative companies take advantage of the opportunities offered in Estonia besides Ajujaht. He pointed out that the programmes and incubation of Science Park Tehnopol, as well as the prototyping funding offered by Prototron, are a very good start-up package for start-ups. ‘In addition to Ajujaht, Raw Edge also participated in the Health Technologies and Services’ research accelerator run organised by the University of Technology and partners,’ Aruoja explained. ‘I invite TalTech researchers and students to meet the team of the Startup Centre of TalTech to discuss opportunities to create and develop science and technology-based businesses.
