To completely utilize a raw material, the side streams first have to be analyzed, then the valuable elements identified and extracted – and should then be put to good use. The Symrise segment Nutrition gets a lot of these side streams from the production of meat (ADF/IDF and Diana Food), fish and shrimp (Diana Aqua) and fruits and vegetables (Diana Food). Diana Nova, the innovation incubator for the segment, has initially chosen 50 side streams thus eight of them makes up around 80 % of all side streams – such as red beet, celery or carrot pulp, egg or shrimp shells or also chicken bones. The researchers investigated their chemical and nutritional-physiological characteristics and checked whether they were appropriate for upcycling. They also considered possible environmental impacts and business potential.

The results – eight products up to now – are not only interesting for the food and animal feed industry. The Symrise business unit Cosmetic Ingredients, for example, can use some of them in cosmetics, like a cranberry side stream consisting of pulp and seeds. The antioxidant, calming, antimicrobial and purifying properties of the fruit can help not only from within in the form of juices and powders but also applied externally as elements of creams.
