New enzyme technology extracts valuable fibers for health benefits and eco-friendly materials.

Scientists are leading the way in a new biotechnology process to maximize the value of sugar beet pulp, a by-product of sugar manufacture. The breakthrough could bring benefits for both human health and sustainable material production.

Professor Anne S. Meyer has guided a research team to develop an enzyme-based process to efficiently isolate sugar beet fibers for a number of high-value applications. One of the ingredients, bioactive pectin fibers, is of potential as a dietary supplement because of its anti-inflammatory activity and positive impact on the gut. The researchers, in association with immunologist Professor Susanne Brix Pedersen, aim to document such benefits and determine optimal means of consumption, such as food additives or capsules.

Beyond uses in foodstuffs, sugar beet cellulose is also finding new uses as a biodegradable plastic. In contrast with cellulose produced from trees that is strengthened through lignin content, sugar beet cellulose contains less lignin and is generally more flexible, allowing for a wide range of uses. Scientists are engineering composite materials in an effort to replace plastics that are still capable of being recycled. This was done in partnership with the EMPA Swiss research institute, widely recognized for cellulose innovation skills.

In addition, sustainability continues to be a priority, with Professor Michael Z. Hauschild heading environmental impact assessments of these processes. There are also novel enzymes and processes in the pipeline for further enhancing plant material processing, which may serve as the cornerstone for future bio-based industries.

This biotech-driven initiative is a perfect example of circular bioeconomy-making maximum possible utilization of each component of a plant into several high-value products. Through the complete utilization of the potential of the sugar beet pulp, scientists are unfolding green horizons in nutrition and materials science with far-reaching implications for global food security and nature conservation.
