Patis: From Fermentation By-product to National Seasoning

Patis is easy to take for granted because its job is often to disappear into a dish. The bottle is opened, a little liquid enters the pot, and attention returns to the soup or stew. Its history becomes more visible when we pause over the bottle itself. How was the liquid made? When do written records first describe it? What changed when a locally traded seasoning became a packaged product? Those questions reveal a story with several stages, rather than a single moment when someone supposedly discovered fish sauce.

An old record prevents a familiar historical mistake

In 1911, Hugo H. Miller’s Philippine commercial-geography textbook already named patis and described extracting liquid from bagoong, followed by boiling and skimming. This is a useful, concrete historical anchor. It means a claim that Philippine patis was first invented several decades later needs to be reconsidered. The record does not tell us the earliest date of its production. It establishes that the name and a method were documented by 1911. The difference between “known by” and “invented in” is small in wording and large in historical accuracy. Source 1

A brand can still have an important founding story. A producer may improve consistency, develop a market, introduce packaging or build a business that many households come to trust. Those achievements deserve their own evidence. They do not require assigning the invention of the entire food to the business. Keeping the histories separate makes each more interesting: one concerns the development of a seasoning; another concerns the people and decisions that helped a particular product reach customers.

A liquid associated with bagoong is not simply waste

The old connection between patis and bagoong is a reminder that the value of a fermentation need not reside in only one form. A solid or paste-like product and its liquid can have different uses. Calling the liquid a by-product may describe how it emerges from a process, but it can also distract from the skill involved in recognising and developing it as a seasoning. For a cook, the relevant question is what the liquid contributes to a meal and how its producer makes that contribution reliable.

The 2011 Codex fish-sauce standard, in the accessible copy marked with 2012 and 2013 amendments, defines a liquid obtained through fish-and-salt fermentation and distinguishes it from products made through acid hydrolysis. That historical document formalises a category already familiar to cooks. It also shows why the broad expression “fish-flavoured liquid” is insufficient. Process, composition and the description on the label are part of identifying what is being sold. This article uses that edition as historical evidence, not as a current manufacturing specification.

Researchers followed what happens inside fermentation

Montri Klitsaneephaiboon’s 1982 UPLB research compared patis made from dilis with patis made from mixed fish at several stages between one and twelve months. The thesis abstract describes studying organisms, amino acids and flavour formation. Its useful contribution here is the attention to both starting material and time. The abstract does not justify saying that every fish sauce reaches the same flavour on the same day. A research sampling schedule describes the investigation; it is not automatically a production timetable for every maker. Source 2

In 1986, Norlita Sanceda, Tadao Kurata and Nobuhiko Arakawa investigated volatile acids in commercial Philippine patis and laboratory preparations. Their abstract reports changes as fermentation progressed and differences between salted and unsalted experimental conditions. This adds another dimension to flavour history: the aroma of a fermented seasoning develops through a process that can be studied, rather than being an unchanging property of raw fish. It does not turn a laboratory comparison into a safe recipe for improvising fermentation at home. Source 3

A wider 1988 study by Mizutani and colleagues considered fermented fish products across Asian cuisines and connected their flavour roles with saltiness and umami. The authors also acknowledged unresolved questions about the origins and spread of such foods in the Philippines. Similarity between two condiments is a good reason to compare them; it is not enough to establish the exact route by which one influenced another. Shared ingredients can support a research question without settling its answer. Source 4

The bottle has a history of its own

A 2006 Supreme Court judgment, Twin Ace Holdings Corporation v. Rufina and Company, concerns the reuse of marked bottles by a patis producer. Read as a business record, it makes packaging visible: bottles were valuable, supply mattered, and the cost of new containers affected producers. The judgment discusses both smaller manufacturers and larger companies. The historical point is not that readers should infer a present legal permission to reuse any container. It is that a familiar condiment’s price and reach depended partly on an object usually discarded from its food story. Source 5

That perspective suggests a richer way to preserve a household’s food history. Keep a clear photograph of an old label and record where the bottle was purchased, when it was used and who preferred it. A container can preserve a brand name, a place of manufacture and a way of selling that memory alone may blur. Its survival is evidence of that particular object. It should not be asked to prove that the same product had an unchanged recipe across all years and markets.

Quality cannot be reduced to one visual ranking

The historical Codex edition considers several aspects together, including appearance, composition, hygiene, contaminants and labelling. That breadth is more useful than a claim that the darkest bottle must always be best. A visual observation cannot answer every question about ingredients or handling. The Codex committee’s October 2024 report also records discussion about the fish-sauce amino-acid-nitrogen provision and labelling changes. The continuing discussion reinforces a practical editorial habit: attach a date to a technical standard and consult the applicable current text before giving compliance advice. Source 6 Source 7

For an ordinary kitchen comparison, begin with an achievable purpose. Perhaps you want a seasoning for a clear chicken broth, or a bottle whose flavour suits the way your family makes a dipping sauce. Choose the dish first and compare products in that context. One may suit your preference without earning a universal quality crown. Keep your observation specific—“I preferred this amount in this soup”—and it becomes useful information for the next cook rather than an unsupported claim about every fish sauce.

The product name is worth reading in full

NutriAsia’s current Silver Swan page uses both “Patis” and “Patis Seasoning” in its product-range title. That distinction is enough to justify reading a bottle carefully; it is not enough to infer an ingredient formula from the name alone. A useful comparison would inspect the actual ingredient panels for the products being compared. Product names, recipes and labels can change, and export packs may need a separate check. The example is a reminder to read, not a verdict on either product. Source 8

The cook gives the seasoning its final meaning

In Pepper.ph’s classic chicken-tinola method, patis seasons the ginger-rich broth before the vegetables finish cooking. The bottle’s contribution is judged within the dish. This is one clearly documented contemporary use, not a claim that all tinola must follow the same sequence. It shows how a prepared seasoning can become part of a cook’s own judgement. The producer creates a product with particular qualities; the cook decides how much of those qualities the meal needs. Source 9

If you are recording a family version, ask when the patis enters the pot and what the cook tastes for afterwards. Ask whether a bottle is chosen because of its flavour, price, availability or association with home. Several reasons may coexist. Write them down without improving the story into something more romantic. An ordinary preference, accurately recorded, can tell us more about how a food lives than a grand origin tale with no traceable source.

Patis deserves a history large enough to include fermentation, research, containers, shops and everyday meals. The early written record gives that history a firm point of reference while leaving room for discoveries that could take it further back. The next spoonful belongs to the same continuing story: a product made by someone, chosen by someone else and adjusted to complete a dish. Recognising those connections gives an apparently simple bottle more of the attention it has earned.
