Nisin Price 25KG
Food Industry: Natural Preservation Nisin's main role here is to inhibit pathogenic and spoilage bacteria, extend food shelf life, and reduce reliance on synthetic preservatives (e.g., sodium benzoate) or excessive heat processing (which can damage food nutrients and flavor). Typical applications include: Dairy products: Added to pasteurized milk, cheese, yogurt, and ice cream to prevent the growth of Listeria monocytogenes (a major risk in refrigerated dairy) and spoilage bacteria like Bacillus species. For example, in cheese production, nisin inhibits late blowing (a defect caused by Clostridium tyrobutyricum, which produces gas and off-flavors). Meat and poultry products: Used in processed meats (e.g., sausages, ham, deli meats) and raw poultry to control Listeria monocytogenes and Staphylococcus aureus. It is often combined with other hurdles (e.g., low temperature, modified atmosphere packaging) for enhanced preservation. Canned and bottled foods: Added to acidic canned foods (e.g., canned tomatoes, pickles) or bottled beverages (e.g., fruit juices) to suppress heat-resistant bacterial spores (e.g., Clostridium botulinum spores), allowing for milder heat treatments that preserve food texture and nutrients. Plant-based foods: Used in plant-based meats (e.g., soy-based sausages) and fermented plant foods (e.g., sauerkraut) to prevent spoilage and pathogen contamination, especially during refrigerated storage.
