What Are the Most Effective natural product preservatives for Food?
Natural preservatives wholesale for food products and food industry like natamycin (derived from Streptomyces natalensis), nisin (a peptide produced by Lactococcus lactis), and lysozyme (found in egg whites) are widely used for their antimicrobial properties. Natamycin is particularly effective against molds and yeasts, making it ideal for surface treatment of cheeses and sausages. Nisin primarily targets Gram-positive bacteria, such as Listeria and Clostridium, extending shelf life in dairy and canned foods. Lysozyme, with its ability to break down bacterial cell walls, is often used in wines, cheeses, and processed meats to prevent spoilage. These naturally derived preservatives are favored over synthetic alternatives due to their safety, regulatory approval (GRAS status), and minimal impact on taste and texture. Their applications extend to plant-based products, where they help maintain freshness without chemical additives.

Our range of dairy products ingredients, including our natural preservatives, is designed to meet the highest industry standards, offering safe and effective solutions for food and beverage applications. Learn more about what are dairy ingredients in our comprehensive guide.

How to Preserve Fresh Juice Naturally?
How to preserve food naturally is a common question, especially for highly perishable products like fresh juices, which are perishable due to enzymatic browning and microbial growth. To preserve them naturally, a combination of mild heat treatment (pasteurization at 60–70°C for 30 minutes), natural acids (citric or ascorbic acid), and enzymatic preservatives like lysozyme can be used. Pasteurization helps inactivate spoilage microorganisms, while acids lower the pH to inhibit bacterial growth. Adding lysozyme (0.05–0.1% concentration) further enhances preservation by targeting Gram-positive spoilage bacteria. Refrigeration 4°C) is essential to slow down enzymatic reactions and microbial activity, extending shelf life to 7–10 days while retaining nutritional quality. For cloudy juices, pectinase treatment can improve stability, ensuring a longer-lasting, fresh-tasting product.

Natamycin 95%
https://www.punature-ingredien....ts.com/products/nata

Natamycin is a natural antimycotic product which is classified as a polyene macrolide and can be produced during fermentation by the bacterium Streptomyces spp. Natamycin not only inhibits the growth of different moulds and yeasts broadly and high-effectively, but also inhibits the production of their toxin. It can be widely used in food preservation and anti-fungal treatment. Natamycin has no effect on bacteria, so it does not prevent in the natural maturing process of yoghurt, cheese, fresh Ham, sausage, etc.

Natamycin 95 Product Detail

Specification: Meet the GB25532-2010 and FAO / WHO standards

Natamycin 95% Uses and Safety
Applications: Natamycin（95%） can be added directly to foods by mixing, dipping or spraying. Depending on the application, the amount of natamycin needed varies. To prevent growth of all known food spoilage yeasts and moulds, up to 0.01g/L or 0.04 g/gallon is sufficient.

Surface Spraying: Block cheese and shredded cheese, Salami and other sausages.
