Calcium gluconate is an organic calcium salt widely used in food and pharmaceutical products, primarily for calcium supplementation and the treatment of calcium deficiency. During the processes of oxidation, fermentation, and degradation, glucose can produce a small amount of oxalic acid as a ...

The choline chloride content is a core indicator of choline chloride wettable powder, directly determining the product's application value and safety. When the content meets the specified standard, it ensures that, as a plant growth regulator, choline chloride effectively promotes the transport of ...

Volatile halogenated hydrocarbons are a class of organic compounds characterized by volatility and halogen substituents, commonly found in industrial solvents, refrigerants, fire extinguishing agents, and other applications. These substances can enter the human body through the respiratory system. ...

Aflatoxin B₁ is a highly toxic secondary metabolite produced primarily by Aspergillus flavus and Aspergillus parasiticus. Among the aflatoxin family, it exhibits the strongest toxicity and the widest distribution. It exerts its toxic effects by inhibiting intracellular DNA and RNA synthesis and ...

Acesulfame is a food additive with the chemical name acesulfame potassium, also known as A-K sugar. It appears as a white crystalline powder and is an organic synthetic salt. Its taste is similar to that of cane sugar. It is readily soluble in water and slightly soluble in alcohol. It is the fourth ...

This application describes the determination of sulfate in alanine by Wayeal’s ion chromatography. During the production and purification of alanine, sulfate (SO₄²⁻) is a common impurity. By determining the sulfate content, it is possible to assess whether the product meets the relevant pharmacopoei...

In the field of pharmaceutical formulations, stearic acid and its magnesium salt (magnesium stearate), as key excipients, play an irreplaceable role in processes such as tablet compression and granule coating due to their unique lubricating, anti-adherent, and glidant properties. Among them, ...

In manganese dioxide ore, calcium is primarily present in the form of compounds such as calcium carbonate and calcium silicate. During high-temperature smelting, these compounds tend to generate slag with a high melting point, thereby increasing the viscosity of the molten mass and impeding the ...
