Coconut aminos and vinegar: contract manufacturing in Sri Lanka

By the Silk Foods Ceylon Editorial Team

Two SKUs keep turning up in briefs from local brand owners chasing the better-for-you shelf: coconut aminos and coconut vinegar. Both are sap products. Both read as premium. Both arrive at a manufacturer with the same gap in the brief, which is a spec. The Sri Lanka Export Development Board describes coconut vinegar as a double fermentation, yeast converting the natural sugars in coconut sap to alcohol, then a group of bacteria called Acetobacter converting part of that alcohol to acid. Nothing in that description tells a production planner what to build.

This post sets out what a Sri Lankan brand owner has to settle before a first run: which standard applies, what the preservatives schedule allows, which of the manufacturing routes fits, and what the numbers look like on a glass line.

Same sap, two different ferments

Coconut aminos and coconut vinegar are not two versions of one product. They share a feedstock and then diverge. Coconut aminos is coconut sap plus salt, sold as a soy sauce alternative that carries no soy and no wheat. Coconut vinegar is sap or coconut water taken through alcohol fermentation and then acetic fermentation.

That shared feedstock matters commercially. The Sri Lanka Export Development Board groups coconut vinegar with treacle, jaggery and coconut sugar as coconut sap based products, all drawn from the same tapping operation. A brand launching aminos and vinegar together is buying into one supply chain, not two, which is the same logic behind a paired kithul and coconut treacle range for the diaspora gifting channel.

The divergence shows up in process time. Aminos is a blend and a hold. Vinegar is two sequential biological conversions, each with its own failure mode, and the second one sets the number that ends up on the label.

Which standard covers a coconut condiment in Sri Lanka?

SLSI’s published catalogue index lists SLS 168 for coconut vinegar, and the entry covers both coconut toddy vinegar and coconut water vinegar. Artificial vinegar sits separately under SLS 625. Treacle has SLS 772. The coconut block of that index carries no entry for coconut sap, coconut sugar, coconut jaggery or coconut aminos.

The practical effect is a split. A vinegar SKU has a written reference point that a buyer, a laboratory and a retailer can all point at. An aminos SKU does not, so its specification has to be authored by the brand and the manufacturer between them, and then held to. That is ordinary in contract manufacturing, but it changes who carries the risk if a batch drifts.

Two cautions are worth stating plainly. Some SLS standards are made compulsory under the Food (Adoption of Standards) Regulations 2008, Gazette 1589/34 of 20 February 2009, and whether coconut vinegar sits on that schedule is a question to put to SLSI at submission rather than an assumption to build a launch on. The same applies to the SLSI clearance window a coconut condiment has to pass through before it reaches a shelf.

The second caution is acidity. No Sri Lankan minimum acetic acid content for vinegar is published free of charge, because SLS 168 is a paid standard. For reference, United States Food and Drug Administration guidance, Compliance Policy Guide section 525.825, treats 4 grams of acetic acid per 100 mL as the benchmark for natural vinegars, and the varieties it lists are cider, wine, malt, sugar and glucose. Coconut vinegar is not among them. A brand that wants a guaranteed acidity printed on its label therefore has to set that figure in its own specification and test every batch against it, rather than inherit one.

The preservative decision is already made for you

The Food (Preservatives) Regulation 2019 was gazetted on 5 March 2019 as Gazette Extraordinary 2113/16 and came into operation on 1 January 2020, rescinding the older 1989 regulations. Its Schedule II works by naming a specified food, then the preservative permitted in it and the maximum level. Vinegar does not appear in that schedule at all.

Regulation 2(b) bars any person from manufacturing a food carrying a preservative other than those specified in Schedule II. Read together, the schedule leaves no permitted preservative for a product sold as vinegar, which means the acidity is the preservation system. That is a reading of the regulation rather than a ruling from the regulator, and it is worth confirming at submission, but it is the reading a formulator has to design to.

The second finding is sharper still. Across the whole of Schedule II, benzoates appear only twice, for carbonated water based flavoured drinks at 120 mg/kg and for artificially flavoured syrup concentrates at 600 mg/kg. No benzoate is listed for any sauce or condiment category. A recipe that came out of a home kitchen or an informal packer carrying sodium benzoate has to be reformulated before it can be made on a certified line, and that reformulation is R&D work, not a substitution.

Preservative limits for condiment categories, Food (Preservatives) Regulation 2019, Schedule II

Schedule II category	Sorbates	Sulphites	Benzoates
Emulsified sauces, 6.1(a)	1,000 mg/kg	300 mg/kg	Not listed
Non-emulsified sauces, 6.1(b)	1,000 mg/kg	300 mg/kg	Not listed
Fruits in vinegar, oil or brine, 3.1(e)	1,000 mg/kg	100 mg/kg	Not listed
Vegetables in vinegar, oil, brine or soy sauce, 3.3(d)	1,000 mg/kg	100 mg/kg	Not listed
Vinegar as sold	Not listed	Not listed	Not listed

Propionates are permitted at good manufacturing practice level in both sauce categories. Anything beyond the preservative list runs through a separate instrument: the Food (Additives - General) Regulations 2019, Gazette 2131/2 of 8 July 2019, also operative from 1 January 2020, which permits the additives in its own schedules and otherwise reads across to the Codex Alimentarius General Standard for Food Additives, unless a product standard made under the Food Act says otherwise. For a founder, that is the short answer on additives: Codex by reference, with local product standards taking precedence.

This is the same spec-limit discipline that governs coconut water powder co-packing, where the carrier percentage sets the spec, applied to a liquid.

What the 2026 labelling regulations changed

The Food (Labelling and Advertising) Regulations 2026 were gazetted on 26 June 2026 as Gazette Extraordinary 2494/47 and came into operation on 1 July 2026. Regulation 16 rescinds both the 2005 regulations, Gazette 1376/9, and the 2022 regulations, Gazette 2319/40 of 14 February 2023. Any artwork built against either of those is out of date, which is covered in more detail in the walkthrough of the 2026 labelling regulations.

Two provisions bear directly on a contract-manufactured condiment. The first is the business-to-business exemption in the proviso to Regulation 3, which releases a B2B food product from the other labelling requirements but still requires the common name, trade name, net contents, date of manufacture, date of expiry, batch number, the manufacturer’s name and address, the distributor’s name and address, country of origin for imports, and a complete ingredient list. It also requires the words “Not for retail sale” in bold type at a font size of not less than 3 mm. That matters for a brand shipping bulk vinegar to a second packer or into food service.

The second is the timing on nutrient declaration. Schedule II extends the mandatory nutrient declaration to all other food products one year after the regulations were published in the Gazette, which puts the deadline in late June 2027. A brand starting artwork now has a dated target rather than an open question.

Contract manufacturing, private labelling or co-packing: which route fits?

The route decides who owns the formulation, who carries the batch risk and how long the first run takes. For a fermented condiment the choice is narrower than it looks, because the starting point is usually a recipe that has never been made at scale.

Manufacturing routes for a fermented coconut condiment

Route	What the brand supplies	What Silk Foods Ceylon does	Fits when
Contract manufacturing	A locked recipe and a written spec	Sources, ferments, fills, labels and releases the finished SKU	The brand already owns a formulation that holds at scale
R&D and NPD, then contract manufacturing	A brief and a target profile	Develops the formulation across sample iterations, then manufactures it	There is no locked recipe yet, which is the usual position on both of these SKUs
Private labelling	A brand and artwork	Supplies an existing catalogue formulation under the brand’s label	An existing SKU already matches the brief
Co-packing	Finished bulk liquid	Fills, seals, labels and packs into retail glass	The brand already ferments its own product and needs retail packs

Coconut aminos and coconut vinegar are not catalogue SKUs at Silk Foods Ceylon today. That rules the private labelling row out for both of them, which is worth saying directly rather than discovering three weeks into a brief. In practice one of two things happens: the project starts in R&D and moves into contract manufacturing once the profile is locked, or bulk liquid arrives from the brand’s own fermenter for co-packing into glass. The wider version of that decision is set out in the comparison of contract manufacturing, private label and co-packing.

What a first run looks like on the glass line

A brief that arrives as a kitchen ferment tends to fail on the same thing, and it is not flavour. It is consistency. A vinegar fermented in an open vessel at ambient temperature drifts in acidity from batch to batch, because the ferment runs on whatever the week’s ambient temperature and the sap’s sugar load happened to be. Tasting panels pass that product. A retail specification does not, because the label carries one number and every batch has to land on it. The R&D screen therefore starts with acidity across repeat ferments before it gets to taste, and a brand that budgeted two sample rounds usually needs four. That is the single most common reason a six-week launch plan becomes a twelve-week one.

For a brand bringing its own bulk liquid to be filled, the run size and the fill format are quoted per project rather than off a published minimum, so that route needs a conversation rather than a number from a blog post. The glass-filling mechanics themselves are the same ones described in co-packing imported olive oil into retail glass.

Where this brief usually goes wrong

Four failure patterns account for most of the stalled coconut condiment projects, and all four are visible in the brief before any money is spent.

The first is treating aminos as a drop-in soy sauce clone. Different feedstock, no soy, no wheat, a different salt load and a different flavour curve. A spec written as “like soy sauce” gives the R&D team nothing to hit, and the iterations that follow are expensive guesswork.

The second is a health claim written into the artwork before anyone checks whether it is permitted. A sap origin is a provenance story, not a claim, and the two are governed very differently. The same line runs through the coconut sugar question of what an origin story can say and a GI claim cannot.

The third is volume. A first run of 300 bottles for a market stall is not what a 200 ml glass line is for, and the first-run minimum of 1,250 bottles is the honest answer rather than an opening position.

The fourth is the calendar. A brand that needs the SKU on shelf in six weeks with no locked recipe has already missed, because sample to first purchase order is 6 to 10 weeks once development sits in front of it, and SLSI submission comes after that. Brands that start from an existing formulation and iterate, as in the flavour-variant route used on coconut jam, get to a shelf materially faster than brands starting from a blank page.

Frequently asked questions

Is there an SLS standard for coconut vinegar in Sri Lanka?

SLSI’s published catalogue index lists SLS 168 for coconut vinegar, covering both coconut toddy vinegar and coconut water vinegar, and SLS 625 for artificial vinegar. No SLS standard is listed for coconut aminos, coconut sap or coconut sugar. Some SLS standards are made compulsory under the Food (Adoption of Standards) Regulations 2008.

Can coconut vinegar sold in Sri Lanka contain preservatives?

The Food (Preservatives) Regulation 2019, Gazette 2113/16, specifies a permitted preservative and a maximum level for each food listed in Schedule II. Vinegar is not listed there. Read with Regulation 2(b), the schedule leaves no permitted preservative for a product sold as vinegar, which makes acidity the preservation system.

Are benzoates allowed in sauces and condiments in Sri Lanka?

Not in any sauce or condiment category. Across Schedule II of the 2019 preservatives regulation, benzoates appear only for carbonated water based flavoured drinks at 120 mg/kg and artificially flavoured syrup concentrates at 600 mg/kg. Sorbates are the permitted option for sauces, capped at 1,000 mg/kg.

What changed in Sri Lankan food labelling in 2026?

The Food (Labelling and Advertising) Regulations 2026 were gazetted on 26 June 2026 as Gazette Extraordinary 2494/47 and came into operation on 1 July 2026, rescinding the 2005 and 2022 regulations. Mandatory nutrient declaration extends to all other packaged food products from late June 2027.

Does Silk Foods Ceylon manufacture coconut aminos or coconut vinegar?

Neither is a catalogue SKU today, so both start as an R&D and NPD brief at the Matale facility and move into contract manufacturing once the profile is locked. First-run MOQ on the 200 ml glass line is 1,250 bottles, produced on a BRCGS and FSSC 22000 V6 audited line.

How Silk Foods Ceylon can help

For local FMCG brands moving a fermented condiment out of a kitchen and onto a retail shelf, Silk Foods Ceylon runs R&D and NPD alongside production planning at a 10,000 sq ft cellular-manufacturing facility in Matale, so formulation work and line scheduling advance in parallel rather than one after the other. First-run MOQ is 1,250 bottles on the 200 ml glass line, which fills up to 2,500 bottles a day, and 1,500 jars on the 300 g glass format at up to 3,000 jars a day. Sample to first purchase order is typically 2 to 4 weeks on a locked recipe and 6 to 10 weeks when development comes first. Production runs on a BRCGS and FSSC 22000 V6 audited line, and SLSI submission support and Sri Lanka Food Act labelling review sit inside the standard engagement.
