Octopus – Price, Identification, Nutrition, and Delicious Recipes

I/ What is Octopus?

Octopus is a well-known ingredient that can be used to prepare various enticing dishes. Let’s explore some basic information about octopus, including its identification, price, selection, preparation, and some delicious recipes.

1. Identification of Octopus

Octopuses are unique creatures characterized by their soft, boneless bodies and remarkable flexibility. They lack external shells, making them agile and capable of squeezing through narrow openings in the ocean floor. Octopus tentacles, known as arms or legs, are the only hard parts of their bodies.

Octopuses have a distinctive appearance, resembling a dome-shaped head with large tentacles attached below. Interestingly, what is often called the “head” is, in fact, the main body of the octopus, housing vital internal organs. One peculiar feature of octopuses is that they have three hearts: two pump blood to the gills, and the third heart circulates blood throughout the body.

The blood of octopuses contains hemocyanin, a copper-based protein responsible for oxygen transport. Although not as efficient as the iron-based hemoglobin found in vertebrates, this protein dissolves in the blood plasma instead of binding to red blood cells, giving octopus blood its distinctive blue color.

2. Nutritional Value of Octopus

Octopus meat is rich in various nutrients, including calcium, potassium, phosphorus, vitamins, and omega-3 fatty acids. These components contribute to boosting the body’s immune system, preventing numerous diseases, and supporting digestion.

– Enhances Immunity: The nutrients in octopus improve the body’s immune response, helping prevent various illnesses.
– Digestive Support: Octopus is a good source of selenium, which aids in protein metabolism and promotes gut health.
– Optimizes Metabolism: Vitamin B12 in octopus is crucial for metabolism, promoting overall metabolic function.
– Cardiovascular Health: Octopus contains octopamine, a compound that can help regulate heart rhythm, potentially benefiting heart health.
– Body Recovery: Grilled or minced octopus can be used to aid body recovery after strenuous work, especially when combined with alcohol or warm water.
– Improves Anemia and Digestion: Octopus is rich in nutrients, especially vitamin B12 and amino acids, which help improve anemia and aid digestion.
– Skin Care: The nutrients in octopus can enhance skin immunity, protect it from UV radiation, and maintain healthy skin.
– Enhances Brain Function: Octopus provides omega-3 fatty acids and important nutrients that promote brain development in children and cognitive function in adults.

Incorporating octopus into your diet can offer various health benefits, including boosting immunity, aiding digestion, optimizing metabolism, protecting cardiovascular health, supporting body recovery, improving anemia, caring for the skin, and enhancing brain function.

IV/ How to Prepare Octopus

When buying frozen octopus, it’s essential to thaw it before processing. You can thaw octopus by placing it in the refrigerator’s chilled compartment for approximately 24 hours.

After thawing, continue by cutting the tentacles away from the octopus body. Use a kitchen knife or kitchen shears to place the octopus on a cutting board and cut each tentacle as close to the body as possible. Repeat this process for the remaining tentacles.

Next, cut the head of the octopus away from the body and split it into two. If necessary, check and remove the octopus’s beak and ink sac. Typically, frozen octopus is already cleaned of its beak and ink sac before packaging. However, if you find that the beak is still inside the body, you can gently push it out with your fingers and then cut it away. Finally, rinse the octopus thoroughly with water mixed with a little vinegar, wine, or crushed ginger to remove any fishy odor.
