Alternative proteins

01Overview and value chain

Markers: [EC: NACE 10.89 (Other food products) | OECD: Food systems | Regulator: FDA (USA), EFSA (EU), MARA (CN)]

The alternative proteins industry produces meat, dairy, and seafood substitutes from plant isolates, fungal mycelium, and precision fermentation. By bypassing animal agriculture, these routes sharply reduce greenhouse-gas emissions, land use, and water consumption while targeting protein densities of 15–25 grams per 100 g, comparable to beef or chicken. Fermentation players now scale submerged bioreactors beyond 100,000 liters, and although end products still trade at a 20–40 percent premium over conventional meat, the sector is shifting from highly processed patties toward cleaner-label whole cuts and cultivated hybrids.

The key directions of alternative proteins are:

1. Plant-Based Extrusion (Twin-Screw / HME): Pea and soy isolates are texturized into fibrous meat analogues using high-moisture extrusion, the workhorse of burger and mince products from Beyond Meat and Planted.
2. Mycoprotein / Biomass Fermentation: Fungal mycelium is grown in submerged bioreactors exceeding 100,000 liters to produce whole-cut meats, pioneered by Quorn and scaled by Meati Foods.
3. Precision Fermentation: Microbes are engineered to secrete functional animal proteins such as soy leghemoglobin (heme) and casein, lending plant bases meat-like flavor and color — the route Impossible Foods commercialized.
4. Cultivated Hybrids: Plant matrices are blended with small amounts of lab-grown animal fat or cells to close the sensory gap for mainstream flexitarian consumers.

Value chain levels

Cross-cutting technologies of the sector:

• Twin-Screw Extrusion: Heat, moisture, and mechanical shear uncoil globular plant proteins and realign them into meat-like fibers (High Moisture Extrusion).
• Submerged Fermentation: Large-scale bioreactors grow fungal mycelium that naturally mimics muscle fibers for whole-cut products.
• Precision Fermentation: Engineered microbes produce specific functional ingredients (heme, casein) to blend with plant bases.

02US

The United States is the birthplace of the modern plant-based boom and remains the largest single market, combining retail dominance with frontier whole-cut mycelium innovation.

Retail dominance, heme engineering, mycelium whole cuts

• Beyond Meat: The category-defining pea-protein burger and sausage brand, distributed across US retail and food service.
• Impossible Foods: Commercialized soy leghemoglobin (heme) through precision fermentation to deliver meat-like flavor and color in its soy-based patties.
• Meati Foods: Pushes the frontier of whole-cut mycelium products, growing mushroom-root steaks and cutlets toward commercial scale.

03CN

China’s alternative-protein push is tied to national food-security goals, with domestic players tailoring products to local cuisine and culinary formats.

Localized analogues, pork substitutes, ready-to-eat meals

• Starfield: Leads localized plant-based beef and pork analogues adapted to Chinese culinary formats.
• Culinary adaptation: Focus on dumplings, dim sum, and ready-to-eat meal formats that match domestic consumption patterns.
• Policy tailwind: National protein-self-sufficiency and food-security targets underpin state and private investment in domestic plant-protein capacity.
• Cultivated-meat frontier: Zhouzi Future Food (周子未来, Nanjing, est. 2020) was spun out of the Nanjing Agricultural University team that produced China’s first cell-cultured meat in 2019; in December 2025 it completed the first 2,000-liter cultivated-pork scale-up run at China’s largest cultivated-meat pilot plant, rated for 10–50 tonnes of product per year.

04EU

Europe is a mature market with strong consumer acceptance, where clean-label extrusion builds on a decades-long mycoprotein legacy.

Mycoprotein legacy, clean-label extrusion, regulatory clarity

• Quorn Foods: The UK pioneer of mycoprotein fermentation, producing fungi-based meat analogues since the 1980s.
• Planted: Swiss clean-label plant meat using pea and sunflower protein cuts without artificial additives.
• Regulatory baseline: EFSA novel-food oversight provides a stable approval pathway for fermentation-derived ingredients.

06Tech stack and innovations

Alternative proteins converge mechanical processing, bioreactor biology, and microbial engineering to replicate the nutrition and sensory experience of animal products.

1. Twin-Screw Extrusion (HME):
   • High-moisture extrusion uses heat, moisture, and mechanical shear to uncoil globular plant proteins and realign them into fibrous, muscle-like structures.
   • The dominant route for pea and soy burgers, sausages, and mince, targeting protein densities of 15–25 grams per 100 g.
2. Submerged Mycoprotein Fermentation:
   • Fungal mycelium is grown in stirred-tank bioreactors scaling beyond 100,000 liters, producing biomass that naturally mimics muscle fibers.
   • Enables whole-cut formats (steaks, cutlets) that extrusion alone cannot achieve.
3. Precision Fermentation:
   • Engineered microbes secrete functional animal proteins — soy leghemoglobin for flavor and color, caseins for dairy — to blend with plant bases.
   • Perfect Day commercialized animal-free beta-lactoglobulin whey using the filamentous fungus Trichoderma reesei, supplying animal-free dairy ingredients to consumer brands since the mid-2010s.
   • Although end products still trade at a 20–40 percent premium over conventional meat, this route steadily closes the sensory and functional gap.
4. Cultivated (Cell-Based) Meat:
   • Animal cells grown directly in bioreactors bypass the live animal entirely. UPSIDE Foods and GOOD Meat became the first companies to win FDA safety clearance and USDA approval to sell cultivated chicken in 2023, with UPSIDE’s whole-cut fillet launching commercially that July from its EPIC plant in California.
   • The frontier shifted to industrial scale in 2025 when Israel’s Believer Meats received an FDA “no questions” letter and USDA clearance for a 200,000-square-foot North Carolina facility designed to produce 12,000 tonnes of cultivated chicken per year.

Stage 1: Basic isolates

Standard soy and pea protein isolates are produced as food-grade powders, the commodity backbone of the category and the starting input for almost every downstream format.

Stage 2: Textured vegetable protein (TVP)

Dry-extruded soy chunks are manufactured for ground-meat applications and ready meals, offering low-cost texture for retail and food service.

Stage 3: High-moisture extrusion

Advanced twin-screw extrusion yields fibrous, chicken- or beef-like textures from hydrated protein melts, enabling cleaner-label whole-muscle analogues.

Stage 4: Biomass fermentation

Mycoprotein (Quorn, Meati Foods) is grown as complete meat alternatives in large submerged bioreactors, producing whole-cut structures that extrusion cannot reach.

Stage 5: Precision fermentation ingredients

Specific animal proteins (heme, casein) are produced in engineered microbes and blended with plant bases to deliver meat- or dairy-like flavor and function.

Stage 6: Cultivated hybrid products

Plant matrices are blended with small amounts of lab-grown animal fat or cells, bridging the sensory gap for mainstream consumers and pointing the sector toward cleaner-label, less-processed next-generation products.
