Pakbet (pinakbet) is a celebrated Ilocano vegetable stew cooked with vegetables — ampalaya (bitter melon), eggplant, string beans, okra, squash (kalabasa), tomatoes, garlic, and ginger — seasoned exclusively with bugguong: the intensely fermented fish paste that is the defining flavour ingredient of Ilocano cooking. The Ilocano diaspora is well represented in Sutherland Shire's Filipino-Australian community, and pakbet appears regularly at Filipino family gatherings and community events.
Bugguong (bagoong monamon — fermented anchovy paste, or bagoong isda more generally) is fundamentally different from the bagoong alamang (fermented shrimp paste) used in kare-kare. Fish fermentation converts TMAO to TMA far more completely than shrimp fermentation — the days-to-weeks fermentation time under salt and anaerobic conditions produces a paste where virtually all TMAO has been converted to TMA. This makes bugguong the highest-TMA condiment in Filipino cooking per gram, and pakbet the highest-TMA vegetable dish when it spills on carpet.
Bugguong TMA: Why Fish Fermentation Is More Intense Than Shrimp Fermentation
Fresh anchovies (dilis, used for bugguong monamon) and other small fish used for fermented fish paste have high TMAO concentrations (30–80 mg/100g) that convert to TMA under the conditions of salt fermentation. The multi-day or multi-week fermentation process under anaerobic conditions (packed in salt, sealed vessels) allows bacterial trimethylamine lyase enzymes to fully convert all available TMAO to TMA. The resulting bugguong paste can have TMA concentrations 5–10× higher than fresh fish or shrimp bagoong. When pakbet is spilled on carpet and the bugguong component contacts the fibre, the TMA adsorption to carpet protein is rapid and persistent.
The high salt content of bugguong (20–30% NaCl by weight, higher than bagoong alamang) creates the same hygroscopic crystal problem as corned beef brine — dried salt residue in the carpet backing draws moisture and promotes mould. Thorough salt rinsing with cold water is essential for any pakbet spill that includes significant bugguong sauce.
Vegetable Chromophores in Pakbet
Pakbet contains one of the widest ranges of vegetable chromophores of any Filipino dish. Eggplant (talong) skin contributes purple-violet anthocyanins (nasunin and related delphinidin glycosides) that shift to olive-brown under the alkaline conditions of baking soda treatment. Kalabasa (Philippine squash, Cucurbita moschata) contributes beta-carotene (orange, fat-soluble carotenoid — but pakbet has minimal fat to carry it, so the beta-carotene is water-suspended and somewhat more accessible to H2O2 than fat-dissolved beta-carotene). Ampalaya, sitaw, and okra contribute chlorophyll that converts to pheophytin. Tomatoes contribute lycopene in small amounts (Ilocano pakbet uses tomatoes sparingly). Okra's mucilaginous polysaccharide (okrin) makes the spill sticky and causes it to spread — this must be removed carefully before blotting.
Treatment Sequence for Pakbet
Remove okra slime before blotting
Okra mucilage (the slippery substance from cut okra) spreads easily when blotted and pushes deeper into the carpet pile. Use a spoon to scoop up all okra pieces first. Blot from the outside edge inward with minimal pressure. Do not rub — rubbing distributes the okra slime into a wider area.
- Remove all vegetable solids (okra first, then eggplant, ampalaya, sitaw, kalabasa, tomatoes) with a spoon. Minimal pressure — okra slime spreads.
- Blot with cold water. For a bugguong-heavy pakbet (more sauce): use extra cold water rinses to dilute and begin removing the salt from the bugguong. The initial cold water application is more about diluting the high-salt bugguong than addressing chromophores.
- Apply baking soda paste (1 tablespoon baking soda + 1 teaspoon cold water). Pakbet is a low-fat dish — the cooking oil used for sautéing is minimal (1–2 tablespoons for a whole pot). Leave 14–16 minutes. The baking soda also helps begin breaking down the okra polysaccharide mucilage.
- Rinse baking soda with cold water. Blot dry. This rinse also removes additional dissolved bugguong salt — do not skip or shorten this rinse.
- Apply enzyme cleaner (protease for fermented fish protein from bugguong and vegetable protein, amylase for okra mucilaginous polysaccharide if available). Leave 18–20 minutes with damp cloth cover. An enzyme product with carbohydrase (polysaccharide-digesting activity) is particularly useful for the okra mucilage.
- Rinse enzyme cleaner with cold water. Blot dry.
- Apply 3% hydrogen peroxide. Leave 8–10 minutes. Blot. The first round addresses eggplant anthocyanin, kalabasa beta-carotene, pheophytin from ampalaya and sitaw, and the small lycopene from tomatoes. A second round may be needed for persistent eggplant anthocyanin or kalabasa orange beta-carotene.
- Apply white vinegar solution (1 part white vinegar, 4 parts cold water). EXTENDED contact time: 10–12 minutes for pakbet, significantly longer than fresh fish dishes. Bugguong monamon has the highest TMA concentration of any Filipino cooking ingredient — full vinegar neutralisation requires the extended contact time. Blot dry.
- Rinse thoroughly with cold water — this final rinse is essential for the bugguong salt. Blot dry.
- Allow to dry completely. Check for white crystalline residue (salt recrystallisation from the bugguong). If present: rinse again with cold water, blot, re-dry.
Pakbet TMA Concentration vs Other Filipino Dishes
| Filipino Dish/Condiment | TMA Source | Relative TMA Level | Vinegar Step Duration | Salt Rinse Needed? |
|---|---|---|---|---|
| Bugguong (fermented fish paste) | Fully fermented TMAO (multi-day) | Very High | 10–12 min | Yes (20-30% NaCl) |
| Bagoong alamang (shrimp paste) | Partially fermented shrimp TMAO | High | 8 min | Yes (18-25% NaCl) |
| Tuyo (dried salted fish) | Partially converted TMAO + salt | High | 8 min | Yes |
| Shrimp sinigang (shell-on) | TMAO from live shrimp | High | 8 min | No |
| Tuna sinigang | Fresh fish TMAO | Moderate-High | 8 min | No |
| Bangus paksiw | TMAO, partially neutralised by cooking vinegar | Moderate | 4–5 min | No |
| Pork sinigang | None (land animal) | None | None | No |
Pakbet Spill in Sutherland Shire?
Bugguong TMA that has penetrated carpet backing is one of the most persistent odour sources in Filipino cooking stains — multiple vinegar applications may not fully neutralise deeply absorbed TMA. Professional hot water extraction combined with an enzymatic pre-spray is the most effective path for large pakbet spills.

Frequently asked
Is Tagalog-style pinakbet (with bagoong alamang) treated differently from Ilocano pakbet (with bugguong)?
Yes — the key difference is the TMA level. Tagalog pinakbet uses bagoong alamang (fermented shrimp paste) which has moderate-high TMA (8-minute vinegar step). Ilocano pakbet uses bugguong (fermented fish paste) with very high TMA (10–12 minute vinegar step). The vegetable chromophores are largely the same, but Tagalog pinakbet sometimes has a more tomato-forward sauce (more lycopene) while Ilocano pakbet is more austere — just the vegetable juices and bugguong without added tomato sauce. The salt rinsing requirement and post-drying salt check apply to both variants.
The pakbet sauce had turned into a thick jelly-like gel from the okra — how does that affect treatment?
Heavy okra mucilage that has gelled in the carpet (from a large okra content or a spill that sat for a while) requires longer enzyme treatment. The okra polysaccharide (okrin, a complex of galactose, rhamnose, and glucuronic acid) gels at concentrations above approximately 1% and is resistant to simple aqueous removal. Apply the enzyme cleaner with a focus on dwell time — extend to 25 minutes, keeping the area moist. If the gel has dried and hardened in the pile, pre-moisten with cold water for 5 minutes before applying enzyme. An enzyme product with pectinase or cellulase activity is helpful for okra polysaccharide specifically.
What is the best way to address the persistent bugguong smell that remains after the vinegar treatment?
If the fermented fish odour persists after the 10–12 minute vinegar step, apply a second vinegar round immediately (do not wait for drying). If odour still persists after the carpet has dried, apply baking soda generously over the dry treated area and leave overnight (8–12 hours). Vacuum thoroughly. Baking soda adsorbs residual TMA compounds and other volatile fermented fish components. For very intense bugguong odour (a large spill of concentrated bugguong paste rather than diluted cooking sauce), professional hot water extraction is the most reliable path — the extraction physically removes TMA-laden water from the carpet backing.
The ampalaya in the pakbet left a faint yellow-green residue — is that the chlorophyll?
Faint yellow-green residue from ampalaya is pheophytin — the magnesium-free form of chlorophyll produced when chlorophyll is heated and slightly acidified (by the vegetable's own organic acids or the bugguong's salt brine). Pheophytin appears olive-yellow on carpet rather than the vivid green of fresh chlorophyll. The H2O2 rounds address pheophytin — if the yellow-green tint persists after 2 rounds, apply a targeted third H2O2 round (with 10-minute dwell time) directly to the discoloured area.
Can fresh ginger in the pakbet cause a stain separate from the other vegetables?
Fresh ginger in pakbet contains gingerols and shogaols (as in tinolang isda and paksiw) — yellow-brown phenolic compounds. However, ginger is used in small quantities in pakbet (a few slices) compared to the dominant vegetable chromophores. The ginger phenolic contribution to the stain is typically masked by the eggplant anthocyanin, kalabasa beta-carotene, and pheophytin from the other vegetables. The H2O2 rounds already needed for those chromophores also address the ginger shogaols. No additional step is required specifically for the ginger component of pakbet.
