Can pomegranates and shrimp be eaten together, can shrimp and pomegranates be eaten together

Vitamin C cannot be eaten with shrimp.

Shrimp cannot be eaten with pomegranate kernels. Shrimp meat contains high protein, calcium, phosphorus and other nutrients, if eaten with foods with high tannin content, it will not only reduce the nutrient content of shrimp meat, but also will make the calcium in it combine with tannic acid to produce an indigestible substance, which may cause physical discomfort.

What is tannin

Tannic acid is a type of tannin obtained from the gallnut tree (Halophyllum sativus) and is a yellow or light brown light amorphous powder or scale; It is odorless, slightly peculiar and extremely astringent. Its aqueous solution and iron salt solution meet to become blue-black, and sodium sulfite can delay the discoloration. Industrially, tannic acid is widely used in tanning and in the manufacture of blue ink.

Tannic acid coagulates proteins.

Solubility of tannic acid

Tannic acid is easily soluble in water and ethanol and almost insoluble in ethers, benzene, chloroform and petroleum ethers. Ellagic acid contains four phenolic hydroxyl groups, which are weakly acidic and soluble in alkaline aqueous solutions and organic solvents such as benzene and ethyl acetate.

Foods containing tannins

Another alias of tannic acid is tannic acid, which is an acidic substance. Tannic acid is found all over nature, and many tree barks contain tannic acid. Pomegranates, apples, pears, grapes and many other fruits contain tannic acid in their cells.

The role of tannins

Tannic acid can be used as a viscosity reducer and a filtration loss reducer for water-based drilling fluids, which can improve the quality of the filter cake. It is also used to tann hides and hides to convert them into leather.

Tannins have the activity of reacting with proteins, polysaccharides, alkaloids, microorganisms, enzymes, and metal ions, and have the characteristics of antioxidant, free radical capture, antibacterial, and derivatization reactions. It is more and more widely used in food processing, fruit and vegetable processing, storage, cosmetics, medicine and water treatment.

Tannic acid can combine with proteins to form water-insoluble tannin proteins, so adding it to shampoos can prevent the dissolution of hair fiber proteins and protect hair, and use it in nail products to increase nail strength.

OK. Shrimp cannot be eaten with the following foods, which do not include pomegranates.

1. Red dates. Jujubes are rich in vitamins, and eating jujubes and shrimp together will cause the vitamins in jujube to reduce arsenic pentoxide in shrimp or shrimp skin to arsenic trioxide (arsenic), thus causing poisoning.

2. Golden gourd. The gourd is cold in nature, sweet in taste, and has the effect of relieving asthma, clearing heat and phlegm. However, shrimp is warm, sweet and salty, and has the effects of tonifying the kidney and strengthening yang, strengthening the stomach and qi, expelling phlegm and anti-cancer; If the two are incompatible.

Eating the same food can cause diarrhea (a disease that is worse than diarrhea), which has a certain damaging effect on physical health.
