First of all, briefly introduce the reed salt.
Lu Hua Haiyan is an old brand of Tianjin Haiyan, and it is an edible sea salt produced by Tianjin Hangu Salt Field. Sea salt is better than other kinds of salt. Historically, it was also a royal tribute salt. Many Tianjin people eat Luhua brand sea salt.
Tianjin Luchang Hangu Salt Field Co., Ltd., a national large-scale sea salt production enterprise, a national edible salt production enterprise, an important national salt production base, and a well-known backbone enterprise in Luchang Salt Area at home and abroad. Now it covers a total area of 96.28 square kilometers, employs more than 4,000 people and has an annual operating income of 2.7 billion yuan.
Second, the definition of salt
Salt refers to a crystalline compound, which consists of cations and anions. In daily life, we usually refer to salt, which is sodium chloride (NaCl).
Salt is named after positive ions and negative ions produced by chemical reactions. Positive ions come from metallic elements and negative ions come from nonmetallic elements or clusters. When these ions combine with each other, a stable crystal structure is formed.
Salt has many important chemical and physiological functions. In chemical reactions, salts can act as catalysts, solvents and electrolytes. In living organisms, the body needs salt to maintain normal cell function, nerve conduction and water balance.
The role of salt
I. Condiments
Salt is an important condiment, which can enhance the taste of food and enrich the taste. Proper amount of salt can improve the umami, sweet and salty taste of food.
Second, food preservation.
Salt can inhibit the growth of microorganisms and prolong the shelf life of food. Especially in the process of curing, curing and dehydrating food, salt is widely used to prevent food from spoilage.
Third, increase the toughness of dough.
In baking, salt can be combined with protein in flour to promote the formation and fermentation of dough and make bread and other baked goods taste better.
Fourth, adjust the pH value of food.
Salt can adjust the pH of food and control the taste and stability of food. In the process of curing, curing and curing, salt can change the organizational structure of ingredients and make them softer and more delicious.
Verb (abbreviation for verb) electrolyte balance
Sodium ion and chloride ion in table salt are one of the important electrolytes in human body. They play a key role in maintaining cell function, regulating water balance and nerve conduction.
