Swedish precision fermentation start-up Melt&Marble has secured self-affirmed GRAS (Generally Recognized as Safe) status in the US for its MeltyMarble fat solution.

The solution is described as a ‘designer lipid,’ made via precision fermentation and inspired by traditional animal-based fats. It is designed to deliver targeted functionality across a range of food applications, including alternative meat and dairy, chocolate confectionery, bakery and snacks.

According to Melt&Marble, the solution is structured to optimise flavour delivery, melting behaviour and creamy or juicy mouthfeel, setting it apart from conventional plant fats and enhancing sensory performance.

It has now determined that MeltyMarble is safe for human consumption based on an extensive testing and quality control status, with the self-affirmed GRAS status paving the way for sales in the US market and unlocking collaboration opportunities with food manufacturers in the country.

Melt&Marble’s process involves engineering yeast to create fats and oils with tailored properties for different applications that meet sustainability and technical requirements. Its mission is to supply high-performance fats to the food market that can replace ingredients derived from petrochemicals, animals and unsustainable plant sources.

Anastasia Krivoruchko, co-founder and CEO of Melt&Marble, said: “This milestone represents a significant step forward for Melt&Marble and underscores our progress across product development, regulatory readiness and scale-up”.

“With self-GRAS achieved, we’re well positioned to advance our food-focused pipeline and pursue a ‘no questions’ letter from the FDA for MeltyMarble, bringing us closer to delivering better and more sustainable fats to the market.”
