We offer a wide range of options for functional bars, both conventional and organic. The range extends from low-sugar protein bars to energy bars with cereal content.

We’re also broadly positioned in vegan powder products. From creamy protein shakes as meal replacements to nutritional supplements in powder form, we offer a wide range of options for functional bars.

What are the particular challenges in developing vegan protein bars compared to conventional ones?
One challenge is certainly that the findings from the development of non-vegan protein bars cannot simply be applied to the development of vegan bars. Plant-based proteins require an entirely new approach to formulation development. For the most part, they bring different functional properties, have different swelling capacities and often lower protein contents.

We study new vegetable protein sources in detail, and conduct extensive trials with new raw materials available on the market in order to select the most suitable ingredients for our bars. The composition of other ingredients is also carefully matched, so as to always achieve the best possible sensory profile.

“The quality of plant protein raw materials has improved greatly in recent years”

Another challenge is the development of organic vegan protein bars, because often the requirements “organic” and “vegan” are coupled. Again, certified organic plant proteins have very different properties from conventional ones and also often have a low protein content. In addition, the organic requirements severely restrict the options for the use of flavorings, which would otherwise contribute to the reduction of vegetable by-notes.

Do vegetable proteins influence texture and mouthfeel?
Yes and no. Vegetable proteins have completely different textures and solubility behaviors from milk proteins. Not only is their water-binding capacity higher, which often results in a slightly dry and sandy texture, but vegan proteins also bring strong vegetable notes to the taste.

However, the quality of plant protein raw materials has improved greatly in recent years, and plant proteins are now available that have increasingly pleasant sensory profiles.

Which vegetable protein sources are suitable for use in vegan protein bars?
The classic protein sources for vegan protein bars are certainly soy, pea and rice protein. But here, too, we have seen strong movements on the market in recent years. While soy, as a common allergen, has seen a drop in consumer acceptance, new types of protein sources are gaining in importance. Fava bean protein, for example, features high protein content and a relatively neutral taste.

Are vegan protein bars just as tasty & creamy as conventional ones?
The old prejudice that vegan bars are sandy and dry can increasingly be refuted. The ongoing improvement of raw materials and recipes will continue to help minimize the sensory differences between vegan and conventional bars in the future, thus meeting the growing demand in the vegan category.

We hope that we have taken another step in the right direction with our latest range of vegan protein bars. For those who would like to try them, we’ll finally be back in person at Vitafoods Europe in Geneva (booth K110) this year. Feel free to come by and see for yourself how wonderfully creamy-crunchy and soft the latest generation of vegan bars can be.
