Nisin Z® (Gram-positive bacterias inhibitor)
Gram positive bacterias like Listeria,Mycobacterium ,lactic acid bacteria,Staphylococcus ,Bacillus and Clostridium are main problem for international food manufacturers .Handary presents Nisin Z and Nisin A as Gram-Positive Inhibitors in different food and acidic beverages.NisinZ® is a naturally occurring antimicrobial peptide produced by the bacterium Lactococcus lactis from sauerkraut. It is used in processed foods to extend shelf life by decomposing Gram-positive bacteria.
Key benefits:Active against a wide range of Gram-positive vegetative bacteria, including Bacillus, Clostridium and Lactobacillus as well as the highly significant Gram-positive pathogen Listeria monocytogenes- Ineffective against yeasts, moulds and Gram negative bacteria.Shelf life extension, Natural, Organic, Non-GMO, Allergen-free and Cost-efficient, Consumer-friendly labelling
Direction for use: In general, to deploy NisinZ® dipping solution with cold boiled water or distilled water, then add directly into foods.Physical/chemical specifications: Light brown to Grey white powder- pH of 1% aqueous solution 2.5-3.5.Storage conditions: store unopened below 20°C in dry conditions, away from direct sunlight and odorous products. When opened, store at approx. 20°C in original container and Shelf life is 24 months when stored according to recommendations. The product is certified by KOSHER, HALAL and ISO22000:2005.
Solubility:Depends on pH for example in 2.5 pH is 4.8 * 106 iu/ml wherease in 5 pH is 1.6* 106 iu/ml.Therefore Nisin is insoluble in alkaline conditions.Stability:Nisin in HCL (pH=3)(121 C°,15min) is completely stable after sterilization.Nisin is a natrual antibacterial peptide that processed by fermenting the sour cabbage of Lactococcus Lactis bacteria.
