What Google Patents search results show about histamine production fermentation patents
If you’re trying to find patents for producing histamine using fermentation on Google Patents, searches typically surface inventions around (1) microbial strains or fermentation processes that generate histamine, and (2) methods to improve yield, control fermentation conditions, or purify histamine from fermentation broths. Your exact results depend heavily on how you phrase the query and which synonyms you include (for example, “histidine decarboxylase,” “histamine-forming,” or “amino acid decarboxylation” rather than only “histamine fermentation”).
How to search better on Google Patents (queries that match “histamine fermentation” better)
People often miss relevant patents if they only search “histamine production fermentation.” Try combining “histamine” with process or enzyme terms that appear in filings:
- “histamine” AND fermentation
- “histidine decarboxylase” AND histamine
- “histamine-forming” AND microbe (or microorganism)
- “amino acid decarboxylation” AND histidine AND histamine
- “biocatalyst” AND histidine decarboxylase AND histamine
- “production” OR “manufacturing” AND (histamine OR decarboxylation)
If you’re looking specifically for “US patents,” filter by country/assignee in Google Patents (US) after the initial search.
Which US patent categories usually cover histamine fermentation
Depending on how the invention is written, US filings you’ll see may fall into these buckets:
- Strain selection or engineering: specific bacteria/yeast capable of converting histidine to histamine (often via decarboxylase activity).
- Process conditions: fermentation parameters (temperature, pH, time, aeration, feed strategy) used to raise histamine yield or reduce byproducts.
- Downstream recovery: purification, separation, and stabilization of histamine from the fermentation broth.
- Safety/quality control: steps to meet purity or microbiological limits, especially where histamine is intended for research or industrial use.
What to do if your search returns no “histamine fermentation” hits
Some patents may not use the word “fermentation” even if the process is bioprocess-based. Expand terms to include:
- “bioconversion”
- “biocatalytic process”
- “decarboxylation”
- “microbial production”
- “enzymatic production”
Also search for the pathway step rather than the product alone: patents may focus on “histidine decarboxylase” activity and only mention histamine as the output.
If you mean histamine from food fermentation (vs industrial histamine production)
Results may differ a lot depending on intent:
- Industrial production of histamine as a product (often via controlled bioprocess steps).
- Histamine formation during food fermentation (where patents may instead target reducing histamine formation, measuring histamine, or improving safety).
- Enzyme inhibitors or process changes to limit histamine buildup in foods.
If you tell me which of these you mean, I can suggest tighter search strings and what to look for in the patent claims.

To pull the right US Google Patents results, reply with one detail:
1) Do you want patents for producing histamine as a chemical product, or for controlling/preventing histamine in fermented foods?
2) Any preferred keywords besides “histamine” and “fermentation” (e.g., “histidine decarboxylase,” “strain,” “purification”)?
