Swiss Origin Labelling, Fermentation Scale-up and Nutrinova

The FSVO clarifies origin information, PROSCALE launches continuous biomass fermentation work, and Mitsui integrates upstream production for Ace-K and sorbates

Switzerland’s Federal Food Safety and Veterinary Office is refining its enforcement interpretation of country-of-production and origin information. At the same time, an EU project involving Austrian and German partners is starting work on scaling continuously fermented proteins. At Nutrinova, control and upstream production for acesulfame K and sorbates are being reorganised.

Switzerland: the FSVO Clarifies the Approach to Origin

On 1 September, the Federal Food Safety and Veterinary Office published Information Letter 2024/2.1. It adds clarification for foods from Israel, Israeli settlements and occupied territories, and clearer wording for meat and fish sold loose. The general obligations concerning country of production and ingredient origin already existed. The letter consolidates the enforcement interpretation of the FSVO and the cantonal authorities; it is not a new legal act [1].

For product ranges sold in Germany, Austria and Switzerland, the distinction between country of production and raw material origin is particularly relevant. An already shaped dough piece imported frozen does not acquire a new country of production merely by being baked in Switzerland. Where flour origin must be declared, the origin of the wheat is relevant, not the milling location. The FSVO also accepts parallel Swiss and EU declarations where their different market references are clearly identified and do not suggest different formulations [1].

For loose sales, the distinction for meat and fish is becoming more specific. Whole products and products in pieces, including processed products, require written information on the animal’s origin. This particular written-information requirement does not apply in the same way to comminuted products such as minced meat or sausages. A product’s physical structure can therefore change its labelling requirements in the Swiss market. For shared German, Austrian and Swiss artwork and catering documentation, origin information should consequently be determined by whether the product is whole, in pieces or comminuted, the processing step and the market version, rather than solely by the product name.

PROSCALE: Continuous Fermentation Aims to Turn Three Protein Routes into a Platform

The four-year EU project PROSCALE began on 1 September. The consortium intends to advance three continuous biomass fermentation processes from technology readiness level 5 to 7, developing mycoprotein and bacterial and yeast-based single-cell proteins with at least 50 per cent protein on a dry-matter basis. Alongside VTT and Wageningen, participants include Circe Biotechnologie in Vienna, the German Institute of Food Technologies and Sinonin Biotech. According to CORDIS, total costs are €8.57 million, with an EU contribution of €6.99 million [2].

The technical core extends beyond the fermenter. Potato, wheat and vegetable side streams, together with by-products from bakery and pasta processes, are to be prepared as substrates; downstream processing and a digital twin are intended to make safety, functionality and resource use manageable together [3]. This integration is crucial for industrial implementation. An inexpensive side stream offers little benefit if inhibitors, variable composition or solids destabilise cultivation and downstream processing.

The stated targets – including production costs 15–30 per cent lower, climate impacts at least 40 per cent lower and five food prototypes – are project objectives. Validated results are not available at the start [2]. Nor has compliance of the future ingredients with the requirements for placing them on the market been established. The microorganism, substrate, manufacturing process, purification and specification will need to be assessed separately for each protein route. For now, PROSCALE is a demonstration platform, not an available ingredient portfolio.

Nutrinova: Bringing Control and Upstream Production Together

Mitsui intends to acquire a further 19 per cent of Nutrinova from Celanese, increasing its holding to 89 per cent. Nutrinova is to become a consolidated subsidiary. Celanese values the proceeds from the share sale at approximately US$152 million and expects completion in the fourth quarter of 2026, subject to customary legal and regulatory conditions [4][5].

Upstream production at Industriepark Höchst is being reorganised in parallel. VP4 Frankfurt GmbH, located at the site, manufactures key intermediates for Nutrinova’s acesulfame K, sorbic acid and potassium sorbate. Celanese is initially to acquire the diketene facility and operate it during a transitional period, after which transfer to Nutrinova is planned. The purchase price, transition period and technical integration plan have not been disclosed [4][5].

For food manufacturers, the significance lies less in the change of ownership than in the vertical integration of a critical production step. Nutrinova will connect upstream raw material production, finished products and quality control more closely. This may strengthen supply security, but it also changes responsibilities, escalation routes and potentially quality-related change processes. Until a specification or site change is communicated, no technical product change can be inferred from the transaction. Nevertheless, supplier approval records should identify who will be responsible for manufacturing, release and change notifications after closing and the transfer of the facility.

Editorial Approval Note

This draft has not been published and is submitted for technical and editorial approval. The FSVO letter describes an authority’s interpretation; specific cantonal enforcement cases have not been reviewed. PROSCALE’s performance, cost and environmental targets come from the project documentation; results and product-specific authorisation routes remain open. The Nutrinova transaction has not yet completed, and the price, timing and technical integration plan for the VP4 transfer are unavailable. The live Food Essentials website and the local news and technical articles have been cross-checked. Searches in Lebensmittel Zeitung and Vegconomist, including Investments & Finance, revealed no apparent duplication of the three selected topics. No additional technical article is currently proposed, as sufficiently robust project results or integration data are not yet available for a more detailed analysis.

Wishing you a successful day, Andreas Gebhart
