What do Google Patents show for “histamine fermentation” (and how to refine the search)?
Google Patents search results depend heavily on the keywords used and how closely they match the claims. If you’re trying to find patents tied to producing histamine using fermentation (biological conversion), start with a few targeted query strings and see which yields the most relevant documents:
- “histamine fermentation”
- “histamine production” fermentation
- “histamine decarboxylase” (often central to histamine formation from histidine)
- “histidine decarboxylase” + histamine
- “biocatalyst” + histamine + (histidine OR decarboxylase)
- “microbial production” + histamine
Also try limiting by field/terms that usually appear in such patents:
- “strain”
- “engineered” OR “recombinant”
- “bioreactor”
- “decarboxylase”
- “histidine”
If your first search returns food- or spoilage-related fermentation patents (where histamine is an undesirable byproduct), add “production,” “biocatalytic,” “controlled,” “purification,” or “manufacturing” to steer toward intentional production.
What “histamine fermentation” patents are usually about (process vs. organism vs. purification)?
Patents in this space typically fall into one of these buckets:
- Creating histamine biologically from histidine using an enzyme (often decarboxylases) or engineered microorganisms.
- Methods for growing and controlling fermentation conditions to drive histamine yield and minimize side-products.
- Downstream processing steps to isolate or purify histamine from a fermentation broth.
If you see terms like “decarboxylase,” “histidine decarboxylase,” or “engineered strain,” you’re likely looking at controlled production rather than incidental formation in foods.
How can you tell from claims whether it’s true “fermentation production” versus food spoilage?
A key distinction in patents is intent and control:
- Production patents usually claim a method for manufacturing histamine, often with controlled bioculture conditions and purification steps.
- Spoilage-related patents often focus on preventing histamine formation or detecting histamine in fish/food systems.
In Google Patents, look for claim language such as “producing,” “manufacturing,” “fermenting,” “bioreactor,” “culturing,” and “isolating/purifying histamine” rather than “preventing,” “inhibiting,” or “detecting histamine.”
What related keywords can surface “histamine production” patents that don’t say fermentation?
Some patents avoid the word “fermentation” even when the process is microbial/enzymatic. To catch these, use adjacent terms:
- “enzymatic conversion of histidine to histamine”
- “biocatalytic decarboxylation”
- “microbial decarboxylation”
- “cell-free” systems (if they use purified enzymes rather than whole-cell fermentation)
- “immobilized enzyme” or “immobilized cells”
If you search only “histamine fermentation,” you can miss patents that describe an enzyme process, immobilized biocatalysts, or microbial biotransformation without calling it fermentation.
If you want: I can point you to the best Google Patents results—what to share
To identify the most relevant Google Patents hits, tell me one of these:
- the time range (e.g., last 5–10 years),
- whether you mean food-grade production vs. industrial synthesis,
- whether you’re focused on enzymes/strains or the full process (fermentation + purification),
- any additional keyword you saw (company name, enzyme name like “histidine decarboxylase,” or a country).
With that, I can suggest a short set of precise Google Patents search queries that are likely to match the patents you want and help you interpret what the claims are covering.
