L-Cysteine, Industrial Grade, is a sulfur-containing non-essential amino acid, whose core functional group is the sulfhydryl group (-SH). It typically appears as a white crystalline powder or granules with a slight characteristic sulfur odor.

Sodium Metabisulfite is an inorganic compound that can be viewed as the condensed product of two molecules of sodium bisulfite. It appears as a white or yellowish crystalline powder with a strong, pungent sulfur dioxide (SO₂) odor.

Xanthan Gum, Industrial Grade, is a high molecular weight polysaccharide polymer produced by the fermentation of Xanthomonas campestris. Its production standards and quality control focus on meeting the performance requirements of industrial applications rather than food safety.

Citric Acid, Industrial Grade, is an important organic acid primarily produced by microbial fermentation. It appears as white or slightly yellow crystalline powder or granules, is odorless, and has a strongly sour taste.

L-Cysteine is a conditionally essential amino acid containing a sulfhydryl group (-SH), which grants it unique reductive and reactive properties. When used as a flour treatment agent, it typically appears as a white crystalline powder or granules.

Xanthan Gum, Food Grade, is a microbial extracellular polysaccharide produced through pure culture fermentation of Xanthomonas campestris, meticulously refined in strict compliance with food safety standards.

Sodium Bicarbonate, Food Grade, commonly known as Baking Soda, is an alkaline substance produced in strict compliance with food safety standards for use in food and related areas. It appears as a white crystalline powder or fine granules, is odorless, and has a slightly salty taste.

Citric Acid, Food Grade, is an important organic acid widely found in fruits like lemons and citrus. Industrially, it is primarily produced by microbial fermentation. It appears as colorless transparent crystals, white crystalline powder, or granules, is odorless, and has a strongly sour taste.

Magnesium Chloride, commonly encountered as the hexahydrate (MgCl₂·6H₂O), is an important inorganic chloride. It appears as white or slightly yellow, grayish-white flakes, crystals, granules, or powder.

Sodium Sulfate, Anhydrous, commonly known in industry as Thenardite or Salt Cake, is an inorganic sulfate salt. It appears as a white crystalline powder or granules, is odorless, and has a bitter-salty taste. Its aqueous solution is neutral.

Sodium Bicarbonate, commonly known as Baking Soda, is a mild inorganic salt and alkaline compound. It appears as a white crystalline powder or fine granules, is odorless, and has a slightly salty taste.

Soda Ash, chemically known as Sodium Carbonate, is a fundamental raw material in inorganic chemical industry. It appears as a white powder or fine crystalline granules, is odorless, and has an alkaline taste.
