Uses and synthesis of Nisin powder

Nisin powder is a peptide antimicrobial substance produced by Streptococcus lactis, consisting of 34 amino acids.Nisin CAS 1414-45-5 is broken down by enzymes into a variety of amino acids when entering the human body, with no residue, no resistance to drugs, and does not affect the human body probiotics.

Applications / Functions of Nisin powder

Nisin Raw Materials is a narrow-spectrum antibacterial agent, which can only kill and inhibit Gram-positive bacteria, and is ineffective against yeast, Gram-negative bacteria and moulds.

Physicochemical Property of Nisin powder

Nisin powder is a peptide antimicrobial agent secreted by Streptococcus lactis, which consists of 34 amino acids.Nisin CAS 1414-45-5 The solubility in water depends on the Ph value, the solubility is 12% at Ph value of 2.5, and decreases to 4% at Ph value of 5.0, and it is insoluble in water under the conditions of neutrality and alkalinity.It is good in heat-resistance at Ph value of 2, and decreases in heat-resistance at Ph value of more than 5. It is not soluble in water under neutral and alkaline conditions.

Production methodprocess of Nisin powder

• Yeast powder is used as raw material and fermented by Streptococcus lactis under certain conditions. The fermentation broth is steam sterilised and then acidified, concentrated, filtered, salted and spray dried to obtain Nisin Raw Materials.
• Nisin powder is obtained from the fermentation mash of a strain of Streptococcus lactis (Lactococcus lactis subsp. lactis) under controlled conditions, then sterilised by steam injection, concentrated by compressed air froth or acidified, salted and spray-dried.
