TECHNICAL DATASHEET

Product: Natamycin 4% Liquid

Active Ingredient: Natamycin (E235)

1. PRODUCT DESCRIPTION & ADVANCED FEATURES

Yotabio® Natamycin 4% Liquid represents a breakthrough in bio-preservation technology. It is a highly stable, ready-to-use aqueous suspension containing 4% active Natamycin (E235). Derived from Streptomyces natalensis, it effectively eliminates the risk of yeast and mold growth in dairy, meat, and bakery products.

Mechanism of Action & The "Reservoir Effect": Natamycin is only active against molds and yeasts when dissolved. Because standard natamycin has a low solubility in water (max ~40 ppm at room temperature), excess material remains as crystals. Our advanced liquid formulation utilizes micro-crystals that dissolve rapidly to provide immediate protection, while the remaining evenly distributed micro-crystals act as "reservoirs"—continuously dissolving to protect the product throughout its entire shelf life.

Unrivaled Advantages over Standard Powder Formulations:

Accelerated Solubility: Micro-crystals achieve maximum dissolved concentration in water significantly faster than standard powders, offering immediate protection in minutes rather than hours.
Negligible Sedimentation: The advanced processing ensures the crystals remain in suspension for days, guaranteeing uniform distribution and preventing the active ingredient from sinking to the bottom of dipping baths or clogging spray nozzles.
Cost-Efficient & Safe: High solubility speed and zero settling mean the product is always present where needed. It provides guaranteed quality with lower overall waste, while eliminating hazardous airborne powder dust in the facility.
Targeted Defense: Does not penetrate deeper than 5mm into the product. It has zero effect on bacteria, ensuring it does not interfere with the natural ripening process of fermented cheeses or dry sausages.

4. APPLICATION AREAS & DOSAGE CALCULATIONS

Application Method	Target Dosage (Active Natamycin)	Yotabio 4% Liquid Preparation Guide
Cheese Brine Baths High salt impairs standard natamycin solubility. Our liquid formulation overcomes this.	5 - 20 ppm (mg/kg) (or 5 - 20 g per metric ton of brine)	Initial Setup: Add 125 ml to 250 ml of Yotabio 4% Liquid per 1,000 Liters (1m³) of brine. Replenishment: Based on daily salt (NaCl) adjustment. If adding 10% new salt volume, add 10% of the initial natamycin liquid volume.
Surface Dipping / Spraying For cheese wheels, dry sausages, and bakery products prior to packaging.	750 - 1000 ppm (Targeting 1-2 mg/dm² on the product surface)	Preparation: Mix 1.88 Liters to 2.50 Liters of Yotabio 4% Liquid per 100 Liters of water. Note: Because of our advanced suspension, continuous heavy stirring is not required during the dipping/spraying process.
Sausage Casings Soaking casings prior to stuffing.	1000 - 2000 ppm	Preparation: Mix 2.5 to 5.0 Liters of Yotabio 4% Liquid per 100 Liters of water. The superior suspension ensures casings are evenly coated during long soaking periods without the active ingredient settling to the bottom.

5. STABILITY & WORKING SOLUTION MANAGEMENT

Thermostability: Yotabio Natamycin 4% Liquid is highly heat stable (can withstand 30 min at 115°C, or hours at 100°C). However, extremely low pH can reduce thermostability.

Sensitivities: Natamycin loses activity when exposed to heavy metals, strong oxidizers (peroxides), Chlorine, and prolonged direct UV light. Ensure water used for dilution is free of heavy chlorine.

Storage of Prepared Solutions (Dipping/Spraying Baths):

It is recommended to use prepared natamycin solutions within 24 hours. While natamycin inhibits yeast and mold, it does not prevent bacterial growth in the water bath.
If the solution must be kept for up to 48 hours, add 8-10% salt to the solution and pasteurize it (e.g., 80°C with minimum holding time).
Note on Pasteurization: Heating and cooling times will deactivate a portion of the active ingredient. Expect approximately a 20% loss of natamycin activity after pasteurization, and adjust your replenishment dosing accordingly.

6. REGULATORY, PACKAGING & STORAGE

Regulatory & Status

Status: Kosher Approved, Halal Approved.

GMO Statement: The product has not been genetically modified according to the definition of Regulation (EC) No 1829/2003 of the European Parliament. The producing micro-organism is of non-GM origin.

Labeling (EU Example): Maximum limits generally dictate 1 mg/dm² surface area (not penetrating deeper than 5mm). Local legislation regarding the maximum allowed limits of Natamycin (E235) must always be consulted prior to use.

Packaging & Storage

Packaging: 25 kg one-way plastic drums. Liquid solutions are preserved to assure microbial quality during shelf life.

Storage: Store between 5°C and 25°C (41°F - 77°F). Protect from freezing. Keep containers tightly closed and away from direct sunlight.

Shelf Life: Should preferably be used within 12 months after the indicated production date. Note: The liquid color may turn somewhat yellowish through shelf-life; this is a natural occurrence and does not affect the efficacy of the product.
