Executive summary

Vietnam's case for alternative protein is a supply case. Vietnam is one of Asia's largest producers of pork, poultry, eggs, farmed fish and shrimp, and exported USD 11.3 billion of seafood in 2025. Almost all of the plant protein that feeds those animals is imported: about 99% of the soy protein in Vietnamese feed and about three-quarters of the maize supply, for a feed-ingredient import bill of roughly USD 10 billion in 2025. In August 2026 fishmeal reached USD 2,500 a tonne, its highest level this decade. The strongest argument for alternative protein in Vietnam is therefore food and feed security, industrial value and trade, not consumer fashion. Environmental and animal-welfare benefits are real motivations for some actors, but narrower ones (Why Vietnam).

This report scopes the supply side: what Vietnam could make, from what, with which equipment, under which rules, at what cost, and who could do it. It covers food and feed; cultivated meat is fully scoped; insects appear as the incumbent benchmark, not as a recommendation.

#Ten findings

1. Carbon-rich, protein-poor. Vietnam grows about 10 Mt of cassava roots and processes about 8 Mt more imported roots, harvests 43.5 Mt of paddy rice and has a sugar surplus. Its protein-rich side streams (brewer's grain, okara) are small next to 7.2 Mt of soybean meal fed each year. The largest residue, cassava pulp, is about 6 Mt wet a year, concentrated in Tay Ninh, but it is low in protein. Cassava roots rose about 75% in price in the year to April 2026 after a supply shortfall, and the E10 fuel-ethanol mandate, in force from June 2026, adds a new buyer (Asset map).

2. Fermentation skills exist but are captive. Vedan, Ajinomoto and Daesang run large aerobic fermentation (our model: 11,000 to 34,000 m³ of tanks) for amino acids. We found no published offer of contract manufacturing. We found no open pilot fermenter, no protein-isolate plant and no domestic textured-protein extruder. Feed mills (269, about half used) and frozen-food co-packers are ready partners (Industrial base).

3. The real non-animal protein economy is traditional. Soy milk, tofu and industrial đồ chay (vegetarian food) dominate. In our audit of 186 products in 11 stores, the median label protein of the 43 foods with a label value was 4.7 g per 100 g, and every locally made product with 10 g or more ran on imported textured soy, soy protein or gluten, mostly Chinese. Modern plant-based meat is nearly absent. The most advanced alternative-protein market is feed: an insect-meal plant sells to a seafood exporter, and Chinese microbial protein is already imported (Alt protein today).

4. Food rules have an open door but no gate. New protein foods are sold through self-declaration, but the law also treats unpermitted "new-technology food" as recallable, and there is no procedure to obtain permission. Precision-fermented proteins probably count as GMO products under a January 2026 decree. Feed is more open: insects, duckweed, algae and yeasts are already on the livestock feed list, though the aquafeed list is unclear. A new Food Safety Law is expected before the National Assembly in its October to November 2026 session (not yet confirmed on the agenda), a one-off window (Rules).

5. Research sits next to alternative protein, not inside it. Vietnam is strong in aquafeed trials, yeast protein expression, stem-cell culture, koji genetics and microalgae, and near zero in texturisation, mycoprotein, precision fermentation and food cell lines. Its novel-food research intensity is about a quarter to a third of Thailand's. The binding gap is shared infrastructure (Knowledge and talent).

6. Capital is thin. One alternative-protein deal has exceeded USD 5 million: Entobel's USD 32.5 million insect-meal plant, financed by local private equity, a development-finance ticket and a seafood exporter's offtake. Agritech venture capital in Vietnam was about USD 1 million in 2025. New state venture funds exist but write small tickets (Capital).

7. Cheap, but not unique, and unready on rules. A regional study scores Vietnam 100 on labour and 0 on regulatory readiness. Indonesia is as cheap; Thailand is nearly as cheap with better rules and sugar. Labour and power are a small share of fermentation cost, so cheap inputs alone will not bring plants. Vietnam exported more than 2 Mt of cassava starch in 2023 and again in 2025, mostly to China, while China imported only USD 0.16 million of glucose syrup from Vietnam in 2024 (Region).

8. Capital, not operating cost, decides fermentation economics. On indicative numbers, fungal feed protein made in Vietnam costs USD 4,050 to 14,700 per tonne of protein, against USD 2,625 to 3,846 for fishmeal protein and about USD 880 for soybean meal. It is marginal as bulk fishmeal replacement, plausible as a functional aquafeed ingredient at 1 to 5% of the diet, and not viable against soy. Textured plant protein costs a small fraction of the retail price of meat protein to make; demand, quality and distribution decide that market (Economics).

9. Two technology families fit now. Textured plant protein, and functional microbial ingredients for shrimp and fish feed. Local legume and rice proteins, fungal foods and duckweed feed are worth proving. Precision fermentation fits only as high-value, low-dose products made under contract. Cultivated meat and seafood are research topics for this decade (Technology fit).

10. The calendar is front-loaded. Almost every relevant rule change lands in 2025 to 2027, so the direction of the next decade will be visible within about 18 months (Outlook).

#What could be done

Ten plays, three robust. We describe ten concrete plays with what must be true, kill tests, first customers and horizons, and score them with weights each audience can change (Plays). Three lead under almost every weighting:

• T1. Domestic textured plant protein for chay brands and frozen-food makers, replacing imports from China (0 to 2 years).
• T2. Functional microbial feed ingredients for shrimp and pangasius, sold on survival and feed efficiency (1 to 3 years).
• T4. A cassava-starch-to-fermentation-sugar hub next to starch factories, to keep a value-adding step in Vietnam (1 to 3 years; needs a committed fermenter).

Shared pilot and tolling fermentation (T5) is what most fermentation plays need first.

Cheap public steps. The four highest-ranked policy options cost little and need no new agency (Policy options):

1. A one-line clause in the new Food Safety Law letting the Government regulate "new foods and new food ingredients" (expected at the October to November 2026 session).
2. A joint note from the agriculture and health ministries on the GMO status of purified precision-fermented proteins.
3. A raw-material section in the aquafeed list.
4. Generic entries for microbial biomass in the livestock feed list.

The larger outlays are a shared pilot fermentation line, public feed trials and a protein-quality laboratory.

#Looking ahead to 2050 (new in edition 1.1)

Part V (Drivers to 2050 to Robust moves) extends the view to 2050. It separates what is near-certain from what is open, labels every forward-looking claim by type (trend, published projection or official target, our estimate, signal, wildcard or vision) and never presents a scenario as a forecast.

1. The pressures point to more imported protein and more compound feed. The working-age population peaks around 2035 to 2040, smallholder pig farms keep disappearing, African swine fever stays endemic, agriculture must cut its emissions to 56 MtCO2e by 2050, and the Mekong Delta keeps sinking by about 1.1 cm a year. No official meat, feed or protein number reaches beyond 2030 (Drivers to 2050).
2. Soybean-meal need rises from 7.2 Mt (2025) to about 10.4 Mt (2050) on trend, nearly all imported; across four scenarios the 2050 range is 7.0 to 11.7 Mt (our model). Vietnam already uses about 4 million hectares of farmland abroad for its feed (Protein balance 2050).
3. Efficiency does twice the work of alternative protein. Better feed conversion and lower soybean-meal inclusion cut 2050 need by 3.4 Mt; a large alternative-protein build-out cuts it by 1.6 Mt. The two add up. Aquafeed is short of omega-3 more than of protein.
4. Frontier technology works, but costs fall slowly. Fermentation industries have cut costs by 13 to 20% per doubling of output, far slower than solar power. Protein from renewable power made in Vietnam could reach the price of fishmeal protein around 2050 at best, and soybean meal's in no year; its window opens not before about 2040 to 2045, and only if five conditions align (Frontier technology).
5. Two external questions decide most: whether imported feed protein comes under chronic stress, and whether Asia's fermentation market stays open or falls under Chinese price dominance. Crossing them gives four worlds for 2050: Regional workshop, Comfortable price-taker, Security build-out and Squeezed importer (Scenarios 2050).
6. Nine no-regret moves pay off in all four worlds, most of them public, cheap and able to start in 2026 to 2028: a national protein and feed balance; a feed-efficiency programme; new-food and new-feed routes with deadlines; shared pilot and trial capacity; a quality laboratory and price series; residue-carbon rules; an omega-3 plan; climate-proof siting; and process-engineering skills (Robust moves).

#For each reader

• Investors: back B2B feed and ingredient revenue with a named strategic buyer, on the Entobel template; underwrite capital intensity, not consumer growth (Investors).
• Policy makers: act on the Food Safety Law window and the two feed-list fixes in 2026 and 2027; favour capital sharing over tax holidays (Policy makers).
• Startups: start where the route is already clear (textured protein, listed feed materials, koji) and sell function or import substitution (Startups).
• Manufacturers: you are the first customer for textured protein, functional feed additives and local drink proteins; a joint trial is the cheapest start (Manufacturers).
• Research bodies: protein-quality data, duckweed safety, soy-wastewater protein in shrimp, thermotolerant strains on cassava and characterised tương strains are the most useful gaps (Research).
• International bodies: support the novel-food drafting, public feed trials, a pilot line and development-finance structures for first plants (International).

#What would change our view

• The Food Safety Law passes without a new-food route, or with one that has no timelines.
• Fishmeal falls back below about USD 1,800 a tonne for a sustained period.
• Chinese microbial protein or textured soy lands in Vietnam below the cost of Vietnamese pilot-scale production.
• An incumbent fermenter offers tolling, which would sharply improve the economics of T2, T3 and T5.

The twenty unknowns that matter most, and who can answer each, are in Unknowns.

About this report. AltProtein Vietnam, edition 1.1, September 2026. Edition 1.0 rested on two waves of desk research, a retail audit in Nha Trang and Ho Chi Minh City, and cross-checks of every headline number against its source. Edition 1.1 adds Part V, built from three further research waves on the futures to 2050, a reproducible protein and feed balance model and 469 new sources (1,275 source records in all). Each claim carries an evidence tag (Vietnam-direct, Vietnam-adjacent or general) and a confidence level, and in Part V a foresight tag (How to read, A. Method, U. Futures method). Earlier drafts contained errors; corrections are listed in B. Corrections. This is scoping research, not investment, legal or engineering advice.
