01 · THE CUSTOMER PROBLEM
A single substitution test cannot resolve shelf life when polymer grade, pH, dose, package, process and product matrix interact.
Mykito turns preservation into a structured program connecting material selection, formulation screening and challenge testing to a measurable shelf-life target.
A structured development program connecting chitosan specification, formulation and challenge testing to a measurable shelf-life target.
02 · RECOMMENDED STARTING POINT
Start with the material designed for the decision.
Because chitosan performance depends on MW, DDA, pH, dose and product matrix, development works best as a designed screening program rather than a single-ingredient substitution test.
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.
Preservative challenge studies
Preservative challenge studies can be developed by matching the chitosan specification, dose and application-ready format to the finished shelf-life development system.
Formula optimization
Formula optimization can be developed by matching the chitosan specification, dose and application-ready format to the finished shelf-life development system.
Package + process integration
Package + process integration can be developed by matching the chitosan specification, dose and application-ready format to the finished shelf-life development 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.
Baseline and target microbiology
Sensory, quality and package endpoints
Target shelf life, scale-up and commercial decision
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 scoped shelf-life program with baseline, screening matrix and decision criteria.
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.
