Natamycin 50% in Lactose--NataPro L50

NataPro L50 is a natural antifungal that the Natamycin mixed in lactose. NataPro L50 is effective in a variety of food products across a wide range of pH levels(3.5-9.5).Natamycin is currently approved by the FDA for use on the surface of cuts and slices of cheese where the standards for such cheese provides for the use of safe and suitable mold inhibiting ingredients. According FDA,72.155, 1994. spraying 200-300mg/kg water solution on the surface of the cheese slice.

Residual less than 10mg/kg.

Potential benefits
Natamycin are effective anti-microbial agents. Using Natamycin as food preservatives can:
1.Enhance the quality of food product, and significantly extend the shelf life of foods by preventing yeast and mould spoilage.
2.Reduce product being recalled resulting from spoilage (and reduces manufacturing costs).
3.Replace or partial replace chemical preservatives and meet consumer demand for food preserved with natural ingredients.
4.Have no adverse flavour to foods.
5.Have stronger inhibitability compared to sorbic acid.
6.Prevent formation of potentially carcinogenic mycotoxins.
7.Cover a very broad spectrum of activity -- most yeasts and moulds are sensitive to very low levels of the preservative (<1 - 20 ppm).
8.Do not act against bacteria .This makes it useful for food products such as cheese and dry sausages in which bacteria are key to the ripening process.
9.Remain on food surface for a long time where contamination usually occurs.
10.Be proven to be a safe antimycotic agent.

Usage levels
The recommended dosages of NataPro L50 is in the range 4—40 mg per kg or litre of food. Exact dosage cannot be stated as it depends on the nature of the product for which it is intended.

Usage Method
NataPro L50 can be added directly to the food as a dry powder or a pre-suspension in water or alcohol. NataPro can be added to heat processed foods by thorough dispersion in the food substrate. Advice avoid process temperature  exceed 100℃.
