Chitosan 101 & The Preservation Challenge

As the food industry moves away from synthetic additives, the demand for effective natural preservation has never been higher.

The global challenge

  • 1.3 billion tonnes of food are wasted every year

  • Spoilage is one of the biggest contributors

What is Chitosan?
Chitosan is a naturally occurring cationic biopolymer derived from chitin (found in insects, fungi, and crustaceans).
It is the second most abundant natural polysaccharide after cellulose.

Key preservation pain points

  • Mold and bacterial spoilage

  • Growing consumer distrust of synthetic preservatives

  • Increasing demand for clean-label ingredients

The solution
A natural, biodegradable antimicrobial that extends shelf life—without labeling or safety concerns.


What Makes Chitonova-60 Unique

Chitonova-60 is engineered with a breakthrough surface charge and optimized for ultra-low-dose performance.

Key advantages

  • +60 mV Surface Charge
    Creates a powerful electrostatic shield that disrupts pathogen membranes on contact.

  • Dual Bio-Sourcing
    Sustainably extracted from Black Soldier Fly larvae and Lentinus mushrooms, ensuring supply-chain resilience.

  • Food-Grade & Safe
    Fully biocompatible, biodegradable, and compliant with food safety standards.

  • Ultra-Low 0.3% Dosage
    Delivers effective preservation for bread, tortillas, and processed foods—without affecting texture or taste.


Electrostatic Antimicrobial Power

How Chitonova-60 Works

Electrostatic Binding
Positively charged amino groups (+60 mV) bind to negatively charged pathogen membranes.

Membrane Disruption
This interaction alters membrane permeability, causing leakage of essential intracellular components—leading to rapid cell death.

Metal Chelation
Binds essential metal ions (Ca²⁺, Mg²⁺), depriving microbes of nutrients required for growth and replication.

Barrier Formation
Forms a breathable polymeric film on food surfaces that limits oxygen transfer and moisture loss, slowing aerobic spoilage.

A multi-mechanism defense—without synthetic chemicals.
