There is no legal route to market

In one paragraph. Before anything can be sold as human food in Vietnam, it has to fit a category in the food safety regulation. Nothing in that regulation describes a protein made by fermentation, or any other food with no history of use in the country. There is no approval process to apply to and no process to be refused by, which is worse than a slow process, because a slow process at least has a defined ending. The animal feed regulation, by contrast, exists: it names an authority and a document set, and it has a published deadline for the cases it covers. Whether it covers a genuinely new raw material, and on what timescale, is the open question of this chapter. And there may be one route into the food regime after all, through a mould Vietnam has been eating for centuries.

7.1 Two regimes, one of which functions#

What this changes. Revised in this version. Chapter 5 recommends biomass fermentation aimed at feed first on price grounds. This adds a second and independent reason: the feed regulator has a defined process and the food regulator has no category. A Vietnamese microbial protein aimed at aquafeed has a named authority and a defined dossier to work against. The same product aimed at human food has neither. [VN-direct]

What it does not change is the timeline. The first version of this report quoted the thirty-working-day clock as the timeline a Vietnamese microbial protein would work against, while stating two paragraphs later that nobody knows how a new raw material joins the list at all. Those two claims cannot both stand, and the optimistic one has been withdrawn. An external reviewer argues that a novel single raw material instead falls under Article 11 of Decree 13/2020/ND-CP, requiring compositional testing, heavy metal assays, mycotoxin screens and controlled feeding trials, at 12 to 18 months. That reading is plausible and unproven: it rests on the same source this study found silent on the question, and the timeline carries no citation of its own. It is recorded as R-C2 rather than adopted.

The open question, now the most urgent in the report. None of the sources consulted explain how a genuinely new single raw material gets onto the permitted circulation list, or whether khảo nghiệm, a formal trial, is required. Until that is answered, no plan or funding application should assume a fast feed route. Open question R-G2, closed by action 3, which is the first letter to send.

7.2 The koji argument#

Aspergillus oryzae has an unusually strong food-safety position for a filamentous fungus: centuries of use in soy sauce, miso and sake, recognition as safe by major authorities, and food strains that produce no aflatoxin despite the organism's relation to A. flavus. It grows on grains, soybeans, bran, pulp, spent grains and oilseed side streams. Protein is commonly 30 to 40 percent of dry mass, varying with substrate and process. Solid-state culture fits traditional practice; submerged culture makes the biomass easier to recover but costs more in equipment. Its enzymes improve softness, binding, juiciness and flavour in structured foods, though the sources show no evidence yet of true whole-cut mycelium products from A. oryzae. [general]

Aflatoxin is not the only safety question. Added in this version. A production strain would also need to be shown not to produce cyclopiazonic acid, kojic acid or 3-nitropropionic acid. That requires strain-level genomic and metabolite characterisation rather than reliance on the species' general safety reputation, and it is a cost on this route whatever the legal answer turns out to be. It should be priced into any koji plan from the start rather than discovered during a challenge.

The Vietnamese argument to test. Vietnam's tương tradition is A. oryzae fermentation. If both the organism and the substrate have a documented history of use in Vietnamese food, the product may fall under Article 4 self-declaration as a processed food, rather than needing a category that does not exist. This is a legal question, not a scientific one, and it is answerable in one letter. If the answer is favourable, it is the fastest route to a marketable Vietnamese alternative protein product found anywhere in this study. Open question R-G3.

One caution on Article 4. Self-declaration permits sale immediately, which makes it tempting to use without asking first. An external reviewer reports that the Vietnam Food Administration challenges self-declarations involving non-traditional ingredients and reclassifies them, with product withdrawal as a consequence. That claim rests on a thin source and is unverified. But the asymmetry is clear enough to act on: a written classification obtained in advance costs a letter, and a reclassification after launch costs the product. Ask first.

7.3 Decree 15/2018 in detail [VN-direct]#

Article 4 sends prepackaged processed foods, additives and processing aids to self-declaration, with sale permitted immediately after the declaration is made. Article 6 requires registration of a product declaration for health-protection foods, medical nutrition foods, special dietary foods, nutrition products for children under 36 months, and food additives with a new function or not on the approved list. Article 8 allows 7 working days for the second group and 21 working days for health-protection foods.

There is no category for a novel food, or for a food ingredient with no history of use in Vietnam.

What that means is unsettled, and this report does not resolve it. A fungal protein or a precision-fermented dairy protein has no named route. It is not established whether such a product would be accepted under self-declaration, treated as an additive with a new function, or refused pending guidance. This is the single highest-value open question in the study. Open question R-G1.

7.4 The ASEAN context#

No ASEAN member state has a framework designed for fermentation-derived or microbial protein.

• Singapore is the only member state with documented approvals. It operates a principles-based test of no significant use as food for at least twenty years, with the developer performing the risk assessment and the Singapore Food Agency evaluating it.
• Malaysia covers only probiotic cultures (Regulation 26A), cultured milk (Regulation 113) and fermented soya bean (Regulation 221) under the Food Regulations 1985.
• Indonesia has a broad biological-source definition of food under Law No. 18 of 2012 and consequent legal uncertainty.
• Thailand has a novel food definition but no documented pathway.

No approval timelines, fees, dossier templates or submission-language requirements are publicly documented for any ASEAN jurisdiction in the academic literature.

One grey-literature timeline exists. GFI India reports Singapore assessment at approximately 9 to 12 months once all required information is submitted. This is an advocacy source, not a regulator statement, and the Singapore Food Agency's own overview page does not state a timeline.

7.5 What a safety dossier would have to show#

Drawn from Codex and European Food Safety Authority practice rather than from any ASEAN instrument: microbiological control, heavy metals in the substrate (cadmium, arsenic, copper, cobalt, chromium, lead), allergenicity screened by sequence and structural comparison with known allergens, antimicrobial resistance, potential to produce toxins, and metabolic profiling where two organisms are grown together.

No Vietnamese study has reported RNA reduction protocols, mycotoxin testing or amino acid digestibility, all three of which the international literature treats as requirements for commercialisation. RNA reduction matters because microbial biomass is high in nucleic acids, which cause gout and kidney stones at high intakes, and is normally dealt with by a brief heat treatment.

7.6 Incentives and capital access [VN-direct]#

• Vietnam's headline corporate income tax incentives are a 10 percent rate for 15 years and a 17 percent rate for 10 years, for encouraged sectors that include high technology, scientific research and technology development, and the processing of agricultural and aquatic products, plus a tax exemption period followed by a 50 percent reduction. The new corporate income tax law took effect on 1 October 2025, with existing arrangements grandfathered.
• The cash grant is far less accessible than the site-selection study implies, and the first version of this report misstated the thresholds. Revised in this version. Under Decree 182/2024/ND-CP, support for fixed asset investment is 1 to 10 percent of the cost of new fixed assets capped at 0.5 percent of total investment capital. On the eligibility floors, the figures given here previously were wrong. The decree sets a minimum of VND 12,000 billion, about USD 470 million, of investment capital or VND 20,000 billion of annual revenue for a high-tech product manufacturing project. Semiconductor and artificial intelligence data centre projects get a lower floor, VND 6,000 billion of capital or VND 10,000 billion of revenue, and industrial biotechnology is not among the sectors given that easement. Research and development centres have a floor of VND 3,000 billion, about USD 118 million, with at least VND 1,000 billion disbursed within three years; they are not exempt from thresholds, as this report previously stated. These figures should be confirmed against the decree text before being relied on. Applications are due by 10 July of the following year.
• The practical reading, which the correction does not change. A first-of-kind alternative protein plant at USD 20 to 50 million clears none of the capital thresholds on either reading. The policy ask is therefore the eligibility floor, not the headline rate. See contradiction R-C1.
• Resolution 36-NQ/TW on biotechnology development is part of the post-2023 policy shift discussed in chapter 14. Its specific provisions were not examined in this study and no claim rests on them.
