01 · THE CUSTOMER PROBLEM
Brands want to reduce selected preservatives or close spectrum gaps without weakening the finished product's protection system.
Chitosan adds a different antimicrobial mechanism that can be screened for synergy with pH, packaging and complementary preservatives.
Chitosan as a complementary hurdle that may strengthen an existing preservation system or reduce the required level of selected preservatives.
02 · RECOMMENDED STARTING POINT
Start with the material designed for the decision.
Its mechanism differs from many conventional preservatives, creating an opportunity to investigate synergy across pH, packaging and complementary antimicrobial ingredients.
Without the shell
Controlled fungal sourcing supports a traceable, non-animal supply strategy.
Specification engineered
MW, DDA, purity, charge density and format are selected around the target result.
Application ready
Powder is only the starting point; Mykito also develops films, fibers, gels, coatings and formulations.
One technical partner
Material selection, formulation support and the validation plan are connected from the first sample.
03 · PERFORMANCE TARGETS
Build toward outcomes a buyer can measure.
Hurdle-system design
Hurdle-system design can be developed by matching the chitosan specification, dose and application-ready format to the finished preservative enhancement system.
Synthetic-preservative reduction
Synthetic-preservative reduction can be developed by matching the chitosan specification, dose and application-ready format to the finished preservative enhancement system.
Spectrum extension research
Spectrum extension research can be developed by matching the chitosan specification, dose and application-ready format to the finished preservative enhancement system.
04 · GO / NO-GO CRITERIA
Define the evidence before testing begins.
The first program is designed around three decision-making outputs—not an open-ended material trial.
Combination dose-response matrix
Finished-form challenge testing
Stability, sensory and cost impact
05 · FROM SAMPLE TO DECISION
A practical application program,
not a bag of powder.
Define
Agree on the function, baseline, constraints and measurable success criteria.
Screen
Select the MW, DDA, purity, dose and physical format that fit the application.
Validate
Test the winning system in the finished formulation, device, process or use environment.
Recommended first request: A low-MW preservative-enhancement grade and factorial combination study.
Start the Sample Brief06 · WHY CHITOSAN
A complementary antimicrobial hurdle
Cationic chitosan can interact with negatively charged microbial surfaces under suitable formulation conditions, while films and coatings retain function where risk is concentrated.
There is no universal concentration. Grade and dose are screened against pH, interacting ingredients, process conditions and the target performance profile.
Target organisms, pH, dose, sensory impact, package and shelf life are validated through finished-form challenge testing.
