Pinakbet is the signature Ilocano vegetable dish — a combination of regional vegetables (bitter melon/ampalaya, eggplant/talong, okra, string beans/sitaw, tomatoes, squash/kalabasa, sometimes winged beans/sigarilyas or torpedo onions) seasoned with bagoong isda (Ilocano fermented fish paste) and cooked until the vegetables are tender. It is one of the most widely cooked Filipino vegetable dishes and is eaten across the Philippines, but the Ilocano version is distinctive for using bagoong isda (fermented whole small fish, with intense fishy TMA) rather than bagoong alamang (fermented shrimp) used in the Tagalog version. The Tagalog pinakbet version is a milder stain; this guide covers the Ilocano variant with bagoong isda.
Pinakbet is the Filipino dish with the widest range of vegetable chromophores in a single spill. The combination of eggplant anthocyanins, squash carotenoids, tomato lycopene, ampalaya pheophytin, and string bean pheophytin all coexist in one sauce. Each chromophore class responds to H2O2 oxidation, but the combination means that 2 complete rounds are needed to address all chromophores rather than the 1 round adequate for single-vegetable dishes.
Pinakbet Chromophore and Stain Component Analysis
| Vegetable | Pigment | Chemical Class | H2O2 Rounds | Urgency |
|---|---|---|---|---|
| Eggplant (talong) skin | Delphinidin-3-rutinoside (purple-dark) | Anthocyanin | 1–2 | High (wool bonding) |
| Squash (kalabasa) | Beta-carotene (yellow-orange) | Carotenoid | 1–2 | Medium |
| Tomatoes | Lycopene (red) | Carotenoid | 1–2 | Medium |
| Bitter melon (ampalaya) | Chlorophyll → pheophytin (olive-green) | Chlorophyll degradation | 1 | Low |
| String beans (sitaw) | Chlorophyll → pheophytin (olive-green) | Chlorophyll degradation | 1 | Low |
| Okra | None (green pheophytin minor) | Mucilage polysaccharide (slippery) | 0 | Medium (spread risk) |
| Bagoong isda | None (brown-grey) | TMA + high salt | 0 | High (TMA + salt crystallisation) |
Okra Mucilage: The Stain Spreader
Okra (okra, Abelmoschus esculentus) produces a viscous polysaccharide mucilage (primarily galacturonan and arabinoxylan) that is released when the okra is cut or cooked. This mucilage is the reason pinakbet sauce is slightly slimy — the okra mucilage disperses throughout the cooking liquid and makes the sauce more viscous than it would be without okra. On carpet, okra mucilage acts as a carrier that helps the other pigments (eggplant anthocyanin, tomato lycopene) spread further across the pile than a non-mucilaginous sauce would. The mucilage also makes the stain feel slightly tacky after drying. Enzyme treatment (the polysaccharide is addressed by amylase) and rinsing removes the mucilage.
Bagoong Isda: Stronger TMA Than Bagoong Alamang
Bagoong isda (Ilocano fermented fish paste, made from whole small fish including anchovy-like fish) contains higher TMA concentrations than bagoong alamang (fermented shrimp paste). The fermented whole fish produces more TMAO-derived TMA per gram than shrimp, and the Ilocano bagoong isda is typically used at higher volume per dish than bagoong alamang in the Tagalog version. The vinegar step is more critical for Ilocano pinakbet than for any other Filipino vegetable dish — 10 minutes rather than the 8 minutes used for bagoong alamang dishes.
Treatment Sequence for Ilocano Pinakbet
Cold water first for eggplant anthocyanin and salt crystallisation
Eggplant (talong) anthocyanins bond to wool keratin within 2–3 minutes. Apply cold water immediately and blot. Also: the high salt from bagoong isda must be diluted before drying to prevent salt crystal formation in Sutherland Shire's coastal humidity.
- Remove solid vegetable pieces (ampalaya, okra, eggplant, sitaw, kalabasa) with a spoon.
- Apply cold water immediately and blot from the outside edge inward. Repeat 2–3 times. This step has two purposes: (1) diluting the eggplant anthocyanin before it bonds to wool keratin; (2) diluting the bagoong isda salt before it dries.
- Apply baking soda paste (1 tablespoon baking soda + 1 teaspoon cold water). Leave 14–18 minutes. Pinakbet is a vegetable dish with minimal fat — pork added to the pinakbet extends the baking soda to 20–24 minutes.
- Rinse baking soda with cold water. Blot dry.
- Apply enzyme cleaner (amylase for okra mucilage polysaccharide and any vegetable starch; protease for bagoong isda fish protein). Leave 18 minutes.
- Rinse with cold water. Blot dry.
- Apply white vinegar solution (1 part vinegar, 4 parts cold water). Leave 10 minutes. The 10-minute dwell (rather than the standard 8 minutes) accounts for the higher TMA concentration in bagoong isda compared to bagoong alamang. Blot dry.
- Apply 3% hydrogen peroxide. Leave 8–10 minutes. Blot. Round 1 addresses eggplant anthocyanin, pheophytin from ampalaya and sitaw, and partial lycopene from tomatoes. Apply a second round for the squash carotene and any remaining lycopene or anthocyanin tint.
- Rinse with cold water. Blot dry. Air-dry with ventilation.
Pinakbet Stain Covering Multiple Chromophores in Sutherland Shire Carpet?
The combination of eggplant anthocyanin, carotenoids, and bagoong TMA creates a complex stain that professional hot water extraction handles more thoroughly than sequential surface treatment. Local carpet cleaning specialists can be matched through referral networks serving Sutherland Shire.

Frequently asked
Is the Tagalog version of pinakbet (with bagoong alamang instead of bagoong isda) treated differently?
Tagalog pinakbet uses bagoong alamang (fermented shrimp paste) rather than bagoong isda. Bagoong alamang has lower TMA per gram than bagoong isda. Reduce the vinegar step to 8 minutes (standard bagoong alamang) rather than 10 minutes (Ilocano bagoong isda). Also, many Tagalog pinakbet recipes add squash more prominently and may include pork at a higher ratio. Otherwise, the chromophore treatment (eggplant anthocyanin, lycopene, pheophytin, carotenoids) is identical to the Ilocano version.
The pinakbet had a lot of okra and it left a slimy residue — how is the mucilage removed?
Okra mucilage (galacturonan polysaccharide) that has dried on carpet feels slightly tacky and may make the pile fibres slightly sticky to the touch. The enzyme amylase partially degrades okra mucilage, but a more specific pectinase enzyme (if available in a commercial product) would be more effective. For most home treatments: apply the amylase enzyme generously to the mucilage area, allow 20 minutes (rather than the 15-minute standard), rinse thoroughly with warm (not hot) water, and blot. If the tacky feeling persists after drying, apply a second enzyme round. The okra mucilage does not add a visible chromophore — the tackiness is the only residual concern.
The bitter melon (ampalaya) left a bitter taste/smell in the carpet — will it affect the carpet long-term?
Ampalaya's characteristic bitterness comes from momordicin and charantin (cucurbitacin-related compounds) that are highly volatile and will evaporate from carpet fibres within 24–48 hours of treatment and drying. These bitter compounds do not bond to carpet fibre and are not a structural stain concern. If a bitter smell persists after 48 hours of drying, apply baking soda (dry) overnight and vacuum — the baking soda adsorbs the volatile bitter compounds.
Can the pinakbet stain permanently discolour white or light wool carpet from the eggplant anthocyanin?
Eggplant (talong) anthocyanin (delphinidin-3-rutinoside) can permanently stain white or light wool carpet if not treated within the 2–5 minute urgency window. The anthocyanin forms ionic bonds with the cystine and lysine residues of wool keratin that are difficult to break with surface H2O2 treatment. On light wool carpet: apply cold water within 2 minutes (urgently), apply H2O2 first (before baking soda, if you must choose) to oxidise the anthocyanin before it fully bonds. On dark carpet: the anthocyanin bond is still problematic but less visible. For established eggplant anthocyanin stains on light wool carpet that have been present for more than 30 minutes, professional treatment is more likely to be required.
Is pinakbet with added pork (sinabawang pinakbet or pinakbet na may baboy) significantly harder to treat?
Pinakbet with pork adds pork fat (15–30% depending on cut used — pork belly is common in pinakbet) and pork myoglobin (0.5–1.2 mg/g). The baking soda extends to 20–24 minutes (pork fat). Add the enzyme lipase to the protease + amylase combination. The chromophore treatment (H2O2 rounds) is unchanged — pork myoglobin in a vegetable-dominant stew is at low concentration compared to a direct meat spill. The eggplant anthocyanin urgency remains the highest-priority treatment for pork-added pinakbet, as it is for the vegetarian version.
