The color of pork is often used as an indicator of its safety and quality. Pork can appear white, pink, or anywhere in between. This leads many home cooks to wonder what color pork should be and whether white or pink pork is better. The color of pork depends on several factors including the breed of pig, diet, age at slaughter, and cooking method. While color alone does not determine quality and safety, understanding what contributes to pork’s appearance can help you select and cook pork properly.
What Makes Pork White or Pink?
Pork ranges in color from pale pink to deep red. The natural color of the meat depends on the breed, age, and diet of the pig.
Pigs that are older and/or more active will have darker colored meat. Younger pigs that are fed a milk-based diet and not allowed to roam typically yield paler colored pork. Certain heritage pig breeds like Berkshire, Red Wattle, and Tamworth are known for their darker, red-tinged meat as well.
The amount of myoglobin, a protein responsible for oxygen delivery, also impacts color. Muscles that get more exercise have higher myoglobin concentrations and thus appear darker.
Finally, the pH of the meat affects its light absorbing properties. A higher pH causes meat to scatter more light waves and look paler. Water content and intramuscular fat levels influence light absorption too.
Is White or Pink Pork Better?
Many people view pale pork as an undesirable sign of poor quality or lack of freshness. In reality, white vs. pink pork offers no definite indication of quality, flavor, or safety on its own.
Both white and pink pork can be juicy and delicious when cooked properly. And neither color means the meat has spoiled. As pork ages, it turns brown or gray due to oxidation, not white.
In general, rosy pink pork has more myoglobin and thus a slightly higher nutritional value. The extra myoglobin also contributes to a strong “pork flavor.” But moderately pale pork when raw can still turn deliciously juicy and pink when cooked.
Color is not a great indicator of safety either. Pork contaminated with harmful bacteria looks, smells, and feels clearly spoiled.
How Should Pork Be Cooked?
Proper cooking is key for safe, high quality pork regardless of its raw color. Use the following evidence-based tips:
– Cook pork to an internal temperature of 145°F/63°C minimum to kill potentially harmful bacteria like salmonella. Use a meat thermometer to verify doneness.
– Let thicker cuts, chops, and roasts rest for 5-10 minutes before slicing to allow juices to redistribute. This helps pork retain moisture.
– Adjust cooking methods and times to avoid overcooking. Well-done gray pork will be dry. For lean cuts like chops and tenderloin, quick cooking methods are best.
– Do not rinse raw pork as this can spread bacteria. Dry brining or marinating adds flavor with minimal moisture loss.
– Choose cooking methods that add some moisture like braising, smoking, or roasting with a pan sauce. Rub with oil or coat in spices to keep lean cuts from drying out.
How to Select Quality Pork
Choosing high quality pork is an important first step. Here is what to look for:
– Color – Pork can range from pale pink to deep red when raw. Both can be good. Avoid pork that looks gray, brown, or green.
– Marbling – Some white intramuscular fat streaking is desirable. It bastes the meat during cooking. Avoid big chunks of fat.
– Firmness – Meat should be firm and spring back when pressed. Pass on pork with an overly soft texture.
– Aroma – Fresh pork has a mild smell. Rancid or strong odors indicate spoilage.
– Packaging date – Choose pork with the latest sell-by date for maximum freshness.
– Label – Look for packages free of rips, leaks, or liquid accumulation.
How to Store Pork
Proper storage preserves freshness and quality. Follow these guidelines:
– Refrigerate pork at 40°F/4°C or colder. Use within 3-5 days of purchase.
– Freeze pork in airtight packaging up to 4 months. Thaw in the refrigerator, not on the counter.
– Rinse pork just before cooking, not when storing. Excess moisture speeds spoilage.
– Place pork in the coldest part of the refrigerator, not the door. Use lower shelves.
– Keep raw pork separate from other foods to avoid cross contamination.

Pork can display a wide range of colors while still being flavorful and safe to eat. The key factors are selecting quality pork, storing it properly, and cooking it thoroughly without overdoing it. While personal preference plays a role, both white and pink pork can deliver an enjoyable eating experience. Focus more on sourcing, handling, and cooking pork properly rather than judging a book by its cover. With the right preparation, pork of any shade can become a delicious and nutritious meal.
