Five Treasures in Fish That Will Surprise You High Nutritional Value in Fish
The nutritional value of fish is very high, and it contains many nutrients that you might not expect, even those you might discard. So, today we'll tell you about these often-overlooked nutrients and how to properly clean fish.
5 Unexpected Treasures on Fish
Fish scales. Fish scales are the outer skeleton of fish, rich in collagen.Protein, calcium, phosphorus, and lecithin, as well as dietary fiber, chitin. Because collagen canbe converted into soluble gelatin at temperatures of 70°C～90°C, a common way to eat it is to make fish scale jelly. The specific method is: scrape off the fish scales and wash them. Place them in a pot filled with water, add somevinegar to maintain the water temperature at 70°C～90°C, simmer over low heat. When the fish scales melt slowly, and the broth thickens, turn off the heat, cool it, and refrigerate it to make jelly. When eating, mix the fish scale jelly with seasonings. Fish bones. Fish bones, also known as fish spines, are rich in calcium and other trace elements. After softening, their nutritional components are easier for the human body to absorb.
Very small, bony fishSmall fish, chew and break them into pieces, and after entering the stomach, the stomach acid will soften the fish bones, promoting the dissolution of nutrients such as calcium and phosphorus. For large fish, suck out the bone marrow, which is the white line in the fish spine. In addition, fish bones can be cooked with vinegar, simmered over low heat (2~4 hours). Note that if you cook with white water, fish bones are difficult to soften, add more vinegar and simmer to utilize the effect of acetic acid to soften the fish bones. Fish ovaries. Fish ovaries contain rich collagen and omega-3 unsaturated fatty acids, which may be beneficial forblood
lipid control. A common method is to wash the fish ovaries with clean water, and cook them with the fish in broth or braise.Fish liver. Fish liver is a place where fish stores various nutrients, such as vitamins A, D, and iron, but its cholesterol and purine content is also high, so it is not suitable for gout patients. Fish liver and fish bile are connected, so when washing the fish liver, do not tear the fish bile.
The liver has detoxification functions and is particularly prone to accumulating toxins. Before eating, make sure the fish is not contaminated by the environment. Fish intestines. Fish intestines have low fat content and protein content is not inferior to fish meat. However, the fish intestines of large fish have edible value. Before eating, you must clean them of the inside contents.
Because the food that fish eats must be digested by the fish intestines, so it is an organ in the fish body that is more likely to be contaminated. If you are not confident in the fish farming environment, it is not recommended to eat. However, the intestines of large fish are edible, and it is necessary to clean them before eating. Because the food eaten by fish must pass through the intestines, it is an organ that is relatively polluted in the fish's body. If you are not confident about the fish farming environment, it is not recommended to eat.
