Why does edible salt have an unpleasant smell?

There may be several reasons for the unpleasant smell of table salt:

1.Salt may be contaminated during the production process due to improper processing, for example, workers may be exposed to external contaminants during the production process, such as dust, foreign bodies, etc., which will cause the salt to emit an odor.

2.The storage environment in which salt is stored may also affect its quality. If table salt is exposed to moisture, the moisture will be absorbed and trigger salt crystallization. This crystallization may cause table salt to take on a foul odor, especially if the crystals adhere to the surface of the salt.

3.Table salt may contain some impurities that can cause the salt to have an unpleasant odor. For example, during the process of drying salt, minerals in the sea may retain some mineral elements in it, which may cause the salt to smell like seawater.

The above information is only some of the possible causes, if the unpleasant smell of table salt is severe or persistent, it is advisable to consult the relevant authorities or professionals for more precise information.

Because table salt is divided into refined salt and dried salt. In the process of drying salt, after sun drying and air drying, the minerals in the sea will retain some mineral elements.

Inside, there will be some smell of seawater. Don't panic, these sea salts are more nutritious than the iodized salt in the mainland.

Be better and eat with confidence!

According to the analysis of the situation, the well salt is related to the ore vein, salt production method, additives, etc., such as the edible salt produced by several salt factories in Henan Province exposed some time ago has a stinky foot smell (formed by a very small amount of short-chain fatty acids such as propionic acid, butyric acid, isovaleric acid, and caproic acid hidden in rock salt deposits).

Sea salt and lake salt remove the impurities mixed in the natural drying process, and a small amount of organic matter will be mixed in the sedimentation process, which will be randomly distributed with decomposition, which will also lead to peculiar smells. In the process of drying salt, after sun drying and air drying, the minerals in the sea will retain some mineral elements in it, and there will be some taste of seawater. Don't panic, these sea salts are rich in nutrients, better than iodized salt in the mainland, so you can eat them with confidence!

SaltThe smell is so bad that it is not poisonous.

**Salt is harmless, not only for adults, but also for babies.

1. The main component of salt is sodium peroxycarbonate.

It will decompose when exposed to water to form ozone and sodium carbonate (small Suda, which can bleach clothes without leaving any impurities, non-toxic, harmless and odorless, food-grade raw materials, green and environmentally friendly. White granular powder, its aqueous solution is alkaline and can be decomposed into sodium carbonate and hydrogen peroxide.

It is usually used as an adjuvant for laundry detergent and has the effect of aerobic bleaching.

2. Salt is not toxic, it is a strong detergent, different from edible salt, many times simply using ordinary detergents, it is difficult to remove these stains in Genzhou, and after a long time, our clothes will naturally have no way to wear them again, but soaking them in salt for a while can remove stains.

3. In the face of this ordinary detergent, which is difficult to remove stains, **salt has a very good effect. In many cases, using ** salt cleaning can completely remove these stains, so that the clothes show a bright and clean color.

Generally, edible salt will not have an odor, the main component of table salt, ionic compounds. Pure sodium chloride crystal is a colorless transparent cubic crystal, due to the existence of impurities, the sodium chloride in general is a white cubic crystal or a fine wide crystal powder, the specific gravity is, the melting point is 801, the boiling point is 1442, the density is gram cubic centimeter, the taste is salty, and it is easy to deliquescent when containing impurities.

Sodium chloride in the solid state does not conduct electricity, but sodium chloride in its molten state conducts electricity. The solubility in water increases slightly with increasing temperature. When the temperature is lower than , NaCl·2H2O dihydrate can be obtained.

Sodium chloride exists in large quantities in seawater and natural salt lakes, and can be used to produce chlorine, hydrogen, hydrochloric acid, sodium hydroxide, chlorate, hypochlorite, bleaching powder and sodium metal, etc., which is an important chemical raw material.

It can be used for food seasoning and pickling of fish, meat and vegetables, as well as for salting soap and tanning leather; Highly refined sodium chloride can be used to make normal saline, which is used in clinical ** and physiological experiments, such as sodium loss, water loss, blood loss, etc. Sodium chloride can be produced by concentrating crystalline seawater or natural salt lake or salt well water.

Salts are chemical compounds composed of metal ions and acid ions; Some salts are bitter and some are sweet; A lot of salt is inedible

Therefore, the answer is: compounds composed of metal ions and acid ions; Not all of them have a salty taste; No, most salt is not edible

The taste of sea salt flavor is as follows:

1. Sea salt has a variety of flavors, the appearance is white, pink, black, gray, etc., white sea salt salt has an earthy fragrance, pink sea salt is produced in the Himalayas, it has a volcanic clay taste. The black sea salt, usually pearly gray with pink, Indian black salt has the strongest sulfuric flavor, and the gray sea salt comes from France, which has a smoky aroma. Edible salt is different, edible salt has been deeply processed, and its taste is very pure, mostly heavy salty.

2. Sea salt is most suitable for decorating dishes, rather than cooking dishes, sea salt has no deep processing, in addition to saltiness, it will also have other miscellaneous flavors. The taste of edible salt is pure, except for the salty taste, there is no other peculiar smell, and the food safety is high, which is incomparable to sea salt, sea salt can be eaten in a short time, not for a long time.

The saltiness is particularly strong, a little stronger than the usual salty taste.

There are generally two types of edible salt: iodized refined salt and seawater salt.

The first one has no flavor, but the other will have some seawater flavor (depending on how it's made, see below).

Knowledge extension: iodized refined salt is prepared by adding potassium iodate or potassium iodide to table salt in a certain proportion. Iodine is an important raw material for the synthesis of essential thyroid hormones, which affect the production, development and metabolism of the body, and the brain is its first target organ. Iodine deficiency in the embryonic and infant stages will lead to different degrees of intellectual disability throughout life.

Iodine is found in nature and is mainly ingested by people from drinking water, food, vegetables, and the surrounding environment. Due to age and physiological differences, infants under the age of 4 need 70 micrograms of iodine per day, adults need an average of 150 micrograms per day, and pregnant women and nursing mothers need about 200 micrograms per day. However, most areas of our country have little iodine, so continuous intake of iodized salt can be intellectual, fitness, and disease prevention.

Seawater salt drying refers to the evaporation of water in seawater through a series of processes to obtain sea salt. The traditional method of extracting salt from seawater is the "salt pan method".

Seawater - evaporation crystallization - precipitation of bitter brine (containing magnesium ions, bromine ions, iodine ions, etc.) and coarse salt (containing sodium ions, chloride ions, magnesium ions, sulfate ions, etc.) - add barium chloride, sodium hydroxide, sodium carbonate in turn. Removal of impurities - filtration - to obtain precipitate and filtrate - to add dilute hydrochloric acid solution - evaporation and crystallization - to obtain pure salt (sodium chloride).

Edible salt white crystals, no special smell. Some of them may have a peculiar smell if they are added with other minerals or used industrial salt to pass off as credit salt!

Edible salt is odorless, industrial salt is, and salt is salty.

Salt doesn't lose its taste, but people lose their taste.

Because salt is the king of all flavors. Hope it helps.
