What To Know

  • When pork is improperly stored or handled, bacteria can break down the amino acid choline into TMA, resulting in a fishy odor.
  • Store pork loin in the refrigerator at a temperature of 40°F (4°C) or below.
  • Marinate the pork loin in a mixture of herbs and spices, such as garlic, rosemary, thyme, or oregano.

Pork loin, a succulent and versatile cut of meat, is a staple in many kitchens. However, an unexpected and disconcerting odor can arise: pork loin that smells like fish. This peculiar phenomenon can leave home cooks perplexed and concerned. In this comprehensive guide, we will explore the causes behind this unusual scent and provide practical solutions to address it.

Causes of Pork Loin Smelling Like Fish

1. Trimethylamine (TMA): TMA is a volatile compound that naturally occurs in fish. When pork is improperly stored or handled, bacteria can break down the amino acid choline into TMA, resulting in a fishy odor.
2. Spoilage: Pork loin that has gone bad due to improper refrigeration or storage can develop a sour, fishy smell. This is caused by the growth of spoilage bacteria that produce off-putting odors.
3. Cross-Contamination: If pork loin is stored or cooked near fish, it can absorb the fishy scent through cross-contamination. This can occur in the refrigerator, on cutting boards, or during cooking.
4. Rancid Fat: The fat in pork loin can become rancid over time, especially if exposed to air or light. Rancid fat can impart a fishy or metallic odor to the meat.
5. Oxidation: Oxidation is a chemical process that occurs when meat is exposed to oxygen. This can lead to the formation of compounds that produce a fishy or stale odor.

How to Avoid Pork Loin Smelling Like Fish

1. Proper Storage: Store pork loin in the refrigerator at a temperature of 40°F (4°C) or below. Use airtight containers to prevent exposure to air and cross-contamination.
2. Freshness: Purchase fresh pork loin from a reputable butcher or grocery store. Avoid buying meat that has been sitting out for an extended period or has an off-putting odor.
3. Separate Storage: Store pork loin away from fish and other seafood to prevent cross-contamination. Use separate cutting boards and utensils for handling different types of meat.
4. Trim Fat: Remove any excess fat from the pork loin before cooking. Rancid fat can contribute to a fishy odor.
5. Cook Thoroughly: Cook pork loin to an internal temperature of 145°F (63°C) to kill bacteria and prevent spoilage.

How to Remove Fishy Smell from Pork Loin

1. Rinse with Water: Rinse the pork loin thoroughly under cold running water. This will help remove any surface bacteria or contaminants that may be contributing to the fishy odor.
2. Soak in Milk: Soak the pork loin in cold milk for 30 minutes to 1 hour. The lactic acid in milk can help neutralize the fishy odor.
3. Use Lemon Juice: Squeeze lemon juice over the pork loin and let it sit for 15-20 minutes. The acidity of lemon juice can help reduce the fishy smell.
4. Marinate in Herbs and Spices: Marinate the pork loin in a mixture of herbs and spices, such as garlic, rosemary, thyme, or oregano. This will help mask the fishy odor and enhance the flavor of the meat.

When to Discard Pork Loin

If the pork loin has a strong, pungent fishy odor, it is best to discard it. This indicates that the meat has spoiled and is not safe to eat. Look for other signs of spoilage, such as a slimy or discolored surface.

Other Considerations

1. Age of Pork: Older pork loin may have a more pronounced fishy odor than younger pork. This is because TMA levels increase with age.
2. Feed: The diet of the pig can also affect the odor of pork loin. Pigs that are fed fish meal or other seafood-based diets may have a more fishy-tasting meat.
3. Packaging: Vacuum-packed pork loin may have a slightly fishy odor due to the lack of oxygen. This odor should dissipate once the package is opened.

Questions We Hear a Lot

Q: Is it safe to eat pork loin that smells like fish?
A: No, it is not safe to eat pork loin that has a strong, pungent fishy odor. This indicates that the meat has spoiled and should be discarded.
Q: How long can I store pork loin in the refrigerator?
A: Fresh pork loin can be stored in the refrigerator for up to 3-5 days. Cooked pork loin can be stored for up to 3-4 days.
Q: Can I freeze pork loin?
A: Yes, you can freeze pork loin for up to 6 months. Thaw the pork loin in the refrigerator before cooking.
