The Big Fat Problem: Rethinking the World's Most Used Ingredient
The global fat ingredient supply chain is concentrated, volatile, and under pressure. We map five technologies racing to replace incumbent fats, and explore what it takes to be fundable in this sector
The global food system runs on fat and yet the infrastructure underpinning its lipid supply chain is destructive for biodiversity, and increasingly volatile. Fat is the second most-used ingredient in commercial food production by volume, a functional super-ingredient determining texture, stability, mouthfeel, shelf life, and sensory appeal across virtually every packaged food category.
Yet today, that system is dominated by two problematic incumbents.
Palm oil, priced at $900-1,050 per ton is estimated to be in more than 50% of packaged food products. It is produced on land cleared from carbon-rich Southeast Asian peatlands and concentrated in two countries (Indonesia and Malaysia) that together control more than 80% of global supply. The EU’s 2021 trans-fat regulation drove mass reformulation into palm oil, which addressed the health angle but increased supply chain risks and biodiversity challenges.
Animal fats face methane regulation headwinds in some regions, margin pressure, and price volatility driven by energy and feed cost. Together, these incumbents represent a $484 billion ingredient market growing at 4.2% CAGR.

Between 2023 and early 2025, cocoa prices surged 321% to an intraday high of $11,722 per tonne dragging cocoa butter, a key specialty fat, into unprecedented price territory and exposing the structural fragility of any lipid ingredient dependent on geographically concentrated agriculture.

Impact
Traditional fat production is carbon-intensive (butter at 12.1kg CO2e/kg, palm at 7.3kg CO2e/litre), drives nearly a fifth of global deforestation, and concentrates 80% of tropical oil supply in Indonesia and Malaysia. Price volatility is worsening across the board, and dairy markets are increasingly erratic as cheese demand diverts milk fat from butter. These converging pressures create the structural case for decoupling high-volume fat production from resource-intensive agriculture.
Technology Landscape
Over the last few years, we’ve seen an increasing number of new technologies and startups emerge to meet the need for alternatives to tackle the many issues traditional fat solutions face. The 33 ventures we’ve identified in the sector have raised more than $497 million in funding historically based on publicly available information. This includes startups which have been acquired and no-longer in operation. We’ve categorised them below into five categories for simplicity and discussed how we view the potential for each technology.

Precision Fermentation
Microorganisms (yeast, fungi) are metabolically engineered to convert sugars into specific and sometimes even designer lipid profiles. The targeted nature enables highly functional products at low inclusion rates - for eg replacing additives with a single clean-label ingredient. Pilot-scale unit economics have been validated by several companies.
Key challenges: High capex, complex downstream processing (DSP accounts for 40–60% of COGS), and EU Novel Food regulatory hurdles. Best suited for premium specialty fats ($5,000–11,000/MT) where bio-manufacturing economics are viable today.
Companies (not exhaustive): Nourish Ingredients, C16 Biosciences, Äio, Melt & Marble, Zero Acre Farms, Sun Bear Bioworks.
Oleaginous Microbial Fermentation
Fat-storing microbes (oleaginous yeast, microalgae) naturally accumulate lipids within their cells when fed sugars or agricultural sidestreams. Simpler extraction than precision fermentation, and CMO production partnerships are often feasible. Lower capex profile than precision fermentation.
Key challenges: Feedstock reliability at commercial scale is unproven beyond certain volumes; narrower functional profiles with non-GMO strains while better functionality with novel strain adds regulatory (EU) timeline risk.
Companies (not exhaustive): Colipi, No Palm Ingredients, Cosaic, GSTransform.
Structuring Technologies (Oleogels & Emulsions)
Liquid seed oils are structured using plant proteins, fibers, and waxes to achieve solid-fat functionality without hydrogenation (i.e.saturated fats). Approaches include oleogels, oleosomes, microgels, encapsulation etc. Better near-term unit economics of all five pathways; regulatory approval is simpler (typically known GRAS ingredients) and better health outcomes for consumers due to low saturated fat.
Key challenges: Label complexity may increase (1 palm ingredient becomes 2–5 components), conflicting with clean-label trends. IP moat is inherently weaker in some cases as it’s replicable by large ingredient companies.
Ventures (not exhaustive): Lypid, Perfat Solutions, Paragon Pure, Fattastic, Gavan.
Cultivated Fat
Animal adipocytes (fat cells) grown in bioreactors from stem cells, replicating animal fat without slaughter. Highest organoleptic precision which makes it uniquely positioned to solve the taste gap in alt-protein through hybrid products. End-products compete with premium animal fats, not commodity palm.
Key challenges: Production costs are typically higher than precision fermentation, capex is quite high, and multiple simultaneous technology breakthroughs are required to achieve scale and feasible unit economics. Regulatory pathway (EU) remains highly complex though quite a few ventures have .
Ventures (not exhaustive): Hoxton Farms, Mission Barns, Culminate Foods, CellVa.
Thermochemical synthesis
This technology utilizes thermochemical synthesis to assemble nature-identical fats directly from carbon dioxide, water, and hydrogen, bypassing agriculture entirely. Zero land use; near-zero carbon footprint with renewable energy.
Key challenges: Highly energy intensive. From a health standpoint, the product will still contain a high level of saturated fat. Trading in the environment upside with a health downside. Consumer perception for such products could also be challenging.
Ventures (not exhaustive): Green-on, Savor
Key takeaways
Based on our research, here’s some of our top criteria while assessing ventures in the space:
Price parity at scale: For specialty fats with low inclusion rates, the economics can work at smaller volumes but producers must backfill missing volume with other ingredients, so net cost-in-use matters more than per-kilogram price. For commodity replacements, the bar is to match palm at $0.90–1.05/kg without subsidising customers.
Drop-in functionality: The most viable alternatives require minimal reformulation, compressing the 18–36 month customer acquisition cycle that keeps producers locked into incumbents.
Processing resilience: Ingredients must survive standard commercial processing requirements like high heat, shear, shelf life stability etc. without functional degradation.
Supply chain decoupling: Traditional fat supply chains are concentrated across a few geographies. Platform technologies that accept broader inputs hold a structural advantage.
Health and label advantage: A fat that decouples taste from health, reducing saturated fat while maintaining full functionality occupies the highest-value position and could build a strong case for premium pricing with food producers.
Strategic Risks
Regulation wildcard: While it can catalyse market-wide reformulation (as with trans fats), Novel Food approval timelines remain a huge barrier. This makes it difficult to back a venture whose thesis relies heavily on regulation easing. Many novel-tech ventures are already pivoting to cosmetics as a bridging strategy, while regulations like the EUDR may independently push producers away from deforestation-linked ingredients in the long-run.
Scale-up economics present a structural challenge: Fermentation-based pathways face high capex for bioreactor capacity and production costs, while some technologies like cultivated fat require multiple simultaneous technical breakthroughs.
Energy and water intensity: While land use is reduced, the energy demand for bioreactors and the water used in processing must be carefully managed to ensure the environmental promise of these technologies is actually realized.
Consumer acceptance: While the technology is maturing, consumer acceptance of some of these technologies is still evolving - especially cultivated fats and chemically engineered fat. We believe consumer adoption will be gradual for some of these technologies.
At Oyster Bay, we believe the venture that wins this market will not necessarily be the one with the most novel science. It will be the one that solves the complete equation: functionality for commercial production, economics that work without subsidy, and a supply chain that solves for today’s vulnerabilities. If it also delivers a step-change in health outcomes for consumers, the investment case is hard to ignore.
