Introduction to Escolar
Escolar, also known as butterfish or white tuna, is a deep-sea fish found in tropical and temperate waters worldwide. It has a distinct oily texture and a rich, buttery flavor that makes it a popular choice for sushi and sashimi. However, escolar is also notorious for causing digestive problems, which has led to it being banned in some countries.
Nutrition Facts of Escolar
Escolar is a good source of protein and omega-3 fatty acids, which are essential for heart and brain health. However, it is also high in calories and fat, with a single serving containing up to 30 grams of fat. This makes it a less healthy choice than other types of fish, such as salmon or cod.
Health Risks Associated with Escolar
Escolar contains a natural wax ester called gempylotoxin, which can cause intestinal distress in some people. Symptoms of escolar poisoning include diarrhea, cramping, and nausea, which can last for several days. In severe cases, escolar poisoning can lead to hospitalization.
Understanding Wax Ester in Escolar
Gempylotoxin is a type of wax ester that is unique to escolar and related species. It is produced by the fish as a defense mechanism against predators, but it can also accumulate in the flesh and cause health problems in humans who consume it.
Symptoms of Wax Ester Poisoning
Symptoms of wax ester poisoning typically appear within a few hours of consuming escolar and can last for several days. They include diarrhea, cramping, nausea, and vomiting. In severe cases, escolar poisoning can also cause headaches, dizziness, and dehydration.
How to Avoid Wax Ester Poisoning
To avoid wax ester poisoning, it is recommended that you limit your consumption of escolar to no more than 6 ounces per week. If you do eat escolar, make sure it is cooked thoroughly, as heat can break down the wax esters and make them less harmful. You should also avoid eating the skin and dark meat, which contain higher concentrations of gempylotoxin.
Cooking Escolar for Safe Consumption
To cook escolar safely, it is recommended that you grill, bake, or broil it until the internal temperature reaches 145°F. This will ensure that any harmful wax esters are broken down and the fish is safe to eat. Avoid frying or sautéing escolar, as this can cause the wax esters to concentrate in the flesh.
Culinary Uses of Escolar in Cuisine
Escolar is a versatile fish that can be used in a variety of dishes, including sushi, sashimi, ceviche, and grilled or baked dishes. Its rich, buttery flavor pairs well with citrus, soy sauce, and other Asian-inspired flavors.
Escolar vs. White Tuna: Differences and Similarities
Escolar is often referred to as white tuna, but it is not actually a type of tuna at all. It is a member of the snake mackerel family, which includes other oily fish like barracuda and king mackerel. However, escolar and white tuna do share some similarities in terms of taste and texture.
Sustainable Fishing of Escolar
Escolar is not considered a sustainable fishery due to concerns over overfishing and bycatch. However, some seafood suppliers are working to promote sustainable fishing practices and reduce the environmental impact of escolar fishing.
Escolar in the Global Market
Escolar is a popular fish in many parts of the world, particularly in Asia and Europe. However, its reputation as a risky food has led to it being banned in some countries, such as Italy and Japan.
Conclusion: Escolar as a Delicacy and a Risk
Escolar is a unique and flavorful fish that has both culinary and health risks associated with it. While it can be enjoyed in moderation and when cooked properly, it is important to be aware of its potential for causing digestive problems. As with all seafood, it is important to choose sustainable sources and support responsible fishing practices.
