Sodium Ascorbate, E301, CAS no.134-03-2, is the sodium salt of Ascorbic Acid and manufacturing process from Ascorbic Acid. It is a white or light yellow crystalline powder, used as nutrition fortifier, antioxidant and preservative in food products such as in meat products, dairy products, and beverages. Sodium ascorbate is widely replaced by sodium erythorbate which has stronger antioxidant ability and will not bring acidic taste.
As an experienced Sodium Ascorbate manufacturer and supplier, we has been supplying and exporting Sodium Ascorbate for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.

Sodium sulfide is a chemical compound known for its multiple industrial applications, primarily in the realm of metallurgy and the production of chemicals. It is a yellow to red solid or solution that serves as a powerful reducing agent, facilitating the removal of oxygen from various metal ores during ore processing, thereby aiding in the extraction of metals like copper, lead, and zinc. Sodium sulfide also plays a role in the leather industry for hair removal during leather processing and in the textile industry for dyeing and desulfurization. Additionally, it is used in wastewater treatment as a precipitating agent for heavy metals and in the production of various organic chemicals. Its versatility as a reducing and sulfur-bearing agent makes sodium sulfide crucial in multiple industrial processes.
