Which foods are prone to melanin deposition?

Melanin is actually a kind of protein, which exists in the basal layer of the skin. When ultraviolet rays irradiate the skin, tyrosine in melanin changes and is secreted into the skin in the form of tyrosinase, and the skin is in a state of "self-protection". Ultraviolet rays stimulate melanin, activate tyrosinase activity and protect our skin cells. Tyrosinase reacts with tyrosine in the blood to produce a substance called dopa. Dopa is actually the precursor of melanin, which is oxidized by tyrosine and releases melanin. Melanin reaches the epidermis through the metabolic layer of cells. Generally speaking, melanin will fall off through metabolism with keratinous dander, or enter the blood circulation system and be excreted. However, if the exposure time is too long and the exposure amount is too much, which can not be eliminated from the skin in time, these excessive melanin will precipitate in the skin, and the uniform precipitation will make the skin look black, and the uneven precipitation will form black spots or deepen freckles. Foods that precipitate melanin easily contain photosensitive factors. After eating these foods, people will be exposed to sunlight or other ultraviolet rays, which will increase the activity of skin melanocytes and make the skin black or spotted. These foods are called photosensitive foods. Common foods prone to melanin precipitation in life are: lemon, radish, papaya, celery, lettuce, potato, coriander, amaranth, rape, eggplant, laver, snail, spinach, fig, nine-story pagoda, leek, red bean, orange, mango and so on.
