What is the white strip in the middle of the spicy duck neck bone?

In the middle of the bone is the bone marrow, and where it connects is the tendon.

Bone marrow introduction: The hematopoietic tissue in the human body, located in the medullary cavity of long bones and all cancellous bones. There are two types of bone marrow in adults:

Red bone marrow and yellow bone marrow. Red bone marrow makes red blood cells, platelets, and various white blood cells. Platelets have a hemostatic effect, and white blood cells can kill and inhibit various pathogens, including bacteria and viruses; Some lymphocytes make antibodies.

Therefore, bone marrow is not only a hematopoietic organ, but also an important immune organ.

Introduction to tendons: Tendons are cord-like or membranous dense connective tissues at both ends of the muscles and abdomen, which facilitate muscle attachment and fixation. The tendons of one muscle are attached to two or more different bones, and it is because of the traction of the tendons that the contraction of the muscles can lead to the movement of different bones.

Each piece of skeletal muscle is divided into two parts: the muscle abdomen is composed of muscle fibers, the color is red and soft, and the tendon is composed of dense connective tissue, the color is white and hard, and there is no contractile ability. Tendons attach skeletal muscles to bones. The tendons of the longus muscle are mostly cord-shaped, and the tendons of the latissimus muscle are broad and thin, membranous, also called aponeurosis.

It's bone marrow. It can be eaten and nutritious.

Beijing's sheep scorpions are specialized in eating the bone marrow inside, both sheep bones and cow bones.

The white stripes in the middle cavity are bone marrow.

The tendons (connective tissues) that are very flexible at the bone junctions are commonly known as tendons.

In either case, it's best not to eat it. The first is that the duck neck is moldy, and these white ones are mold colonies. The second should be potassium sorbate crystals, which are generally added to this packaged cooked food.
