1. Introduction
The coffee industry faces both challenges and opportunities in the quest for sustainability [
1]. Amidst global supply chain disruptions caused by events such as the COVID-19 pandemic and geopolitical conflicts, finding innovative sources for food ingredients is crucial [
2]. Coffee by-products, which are often wasted despite their nutritional value, could play a significant role in enhancing food security and reducing waste [
3]. However, the EU’s novel food regulation [
4] has presented unexpected barriers to harnessing this potential, thereby hindering sustainability efforts in the coffee sector [
5].
2. Coffee By-Products as a Solution
Coffee by-products, such as coffee leaves, cherry materials, and silverskin, have demonstrated their nutritional value and versatility [
6]. These by-products can be used in various applications, from providing essential nutrients to acting as substitutes for conventional ingredients in baked goods, meat products, and more [
3]. The focus on sustainability and reducing waste in the food industry makes these by-products highly attractive, but their utilization is restricted by the current regulatory framework.
3. Regulatory Challenges
The EU’s novel food regulation, while intended to ensure consumer safety and promote innovation in the food industry, has inadvertently posed a significant obstacle to increasing sustainability in the coffee industry through the marketing of coffee by-products [
3,
5]. One crucial aspect contributing to this obstacle is the limited number of coffee by-products that has gained novel food authorization from the EU Commission, with only a few products, such as the infusion from coffee leaves and cascara, falling under this category [
7].
The problem with the current authorization for these two coffee by-products lies in its basis on traditional use in third countries. The authorization granted is specific to the exact details of traditional use, which means that coffee leaves and coffee cherry pulp, for instance, can only be used to prepare beverages and not as ingredients in other food products like bread to increase protein content. For such uses, a separate full novel food application procedure is necessary, an effort that no food business operator has currently made.
This limitation significantly restricts the potential of coffee by-products to contribute to sustainability in the food industry. When innovative uses of these by-products are considered, such as incorporating them into various food products to maximize their nutritional value and reduce waste, the current regulatory framework becomes a hindrance. The inability to flexibly utilize coffee by-products as versatile ingredients in different food applications limits their economic viability and ultimately obstructs efforts to enhance food security and reduce waste within the coffee industry.
To truly leverage the sustainability potential of coffee by-products, a more flexible and adaptable approach within the novel food regulation is required. This should involve re-evaluating the authorization process to allow for broader usage of by-products, enabling them, e.g., to contribute to increasing protein content in bread and other food items, while maintaining a focus on safety (e.g., by restricting caffeine intake).
No authorizations have been applied so far for coffee flowers, parchment, or coffee silverskin [
7].
4. A Call for Revision
To fully unlock the sustainability potential within the coffee industry, a revision of the EU’s novel food regulation is essential. The authors propose several key changes:
Flexible Approval Process: An adaptive approval process that considers the unique characteristics of traditional foods from third countries, allowing not only for exceptions during emergencies and crisis situations but also for staple products that have been used by humans for decades [
3,
5].
Equivalence of Traditional Foods: Traditional foods from third countries should not be bound by overly restrictive categorizations but rather treated as equivalents to traditional foods within EU countries, fostering fair competition [
3,
5].
Balancing Safety and Innovation: Striking the right balance between safety and innovation, recognizing that the responsibility for food safety lies with manufacturers, whether the food is novel or traditional [
3,
5].
5. Conclusions
The coffee industry’s sustainability efforts are impeded by the current rigidity of the EU’s novel food regulation. By focusing on the case of coffee by-products, this paper has highlighted the need for a more adaptive and forward-thinking regulatory approach. Embracing innovative sources of nutrition and fostering sustainable practices should be the shared goal. A revised regulation that promotes both food safety and sustainability can position the coffee industry and other sectors for a brighter, more sustainable future.
