Import Food Additive Preservative Nisin E234 — Buy in wholesale FOB from Supplier in China

Nisin (E234) is a natural antimicrobial polypeptide produced by Lactococcus lactis subsp. lactis. Yotabio Engineering Co. Ltd obtains the active compound through fermentation of a milk‑based medium, after which it is concentrated, dried and standardized with sodium chloride. The resulting product is soluble in aqueous environments and retains activity most effectively at acidic pH, where it also shows heat stability. At the usage levels normally applied in food preservation, Nisin does not alter the colour or flavour of the finished product.

The additive is widely employed in heat‑processed and low‑pH foods such as cheese, processed meats and certain beverages to inhibit Gram‑positive bacterial spoilage, including heat‑resistant spores of Bacillus and Clostridium species. Industry practice grades Nisin by its purity and activity, with commercial batches typically exceeding 90 % purity and delivering at least 1 × 10⁵ IU g⁻¹. Because it has no effect on Gram‑negative bacteria, yeasts or moulds, it is often combined with other preservation methods to achieve broader shelf‑life extension. The standardised form supplied by Yotabio conforms to these typical industry benchmarks.

Importers seeking to source this preservative should request a certificate of analysis confirming purity and activity, and verify the packaging format, commonly 25 kg food‑grade bags. Trade terms, minimum order quantities and Incoterms are not disclosed in the listing and need to be confirmed directly with Yotabio Engineering Co. Ltd. Buyers in dairy, meat processing and beverage sectors frequently purchase Nisin for its proven efficacy and regulatory acceptance in many jurisdictions.

Yotabio Engineering Co. Ltd is located at 398 Huaian Road, Retda, Rizhao, Shandong, China, postal code 276800. The supplier holds a harbour verification tier on the platform, indicating that its business credentials have been reviewed. Its public profile lists a response rate of 0 % and no average response time, suggesting that enquiries may require follow‑up. Yotabio specialises in biotechnology processes, as reflected by its production of fermented food additives such as Nisin.

The company’s current listing provides a technical description of Nisin E234, including its antimicrobial properties and standardisation with sodium chloride, but does not disclose specific pricing, minimum order quantities or certification details. Prospective buyers should therefore request a formal quotation and any relevant quality certificates directly from Yotabio. No additional corporate history, employee count or client references are supplied in the available data.
