Method & Evidence

AimTo develop and evaluate a chitosan/cellulose nanofibril (CNF) nanocomposite coating for its effectiveness in preserving the postharvest quality of strawberries.
MethodExperimental research with comparative analysis.
ProcedureThree coating formulations (1% chitosan, 1% chitosan + 3% CNF, and 1% chitosan + 5% CNF) were prepared. Strawberries were coated and stored under cold conditions. Various quality parameters including color, thickness, water vapor permeability, mass loss, firmness, soluble solid content, pH, titratable acidity, vitamin C, phenolic compounds, anthocyanins, and enzymatic activities were analyzed.
ContextFood science and postharvest technology.

Variables

IV["Concentration of cellulose nanofibrils (CNF) in the chitosan coating."]
DV["Postharvest quality of strawberries (e.g., mass loss, firmness, color, soluble solid content, vitamin C, anthocyanins)."]
CV["Chitosan concentration, storage temperature, storage duration, type of fruit (strawberries)."]
