Tiramisù Spoilage Calculator

Predictive screening for refrigerated tiramisù shelf life — yeast (Z. bailii) & mold (P. roqueforti) worst-case model.

Bias mode

§ 00Animation

mold colonies — rendered on the compartment where they grow (lid underside, cup rim, cocoa surface, cup wall) — independent populations, no transfer
cream layer tint = yeast log10 N / Nmax · headspace tint = pCO₂
days / sec
t = 0.00 d  /  — d  ·  idle

§ 01Storage

§ 02Compartments

Enter post-equilibration aw and pH. v1 has no cross-compartment transport.

§ 03Headspace & packaging

§ 04Preservatives

Per-compartment. Toggle and set ppm; both are needed for the preservative to act.

§ 05Bioburden

Ingredients (mass into compartment in g; CFU/g)

Cocoa (dosed to cocoa_surface)

Container & lid surfaces (CFU/cm²)

Airborne (total CFU per cup during filling)

§ 06Transport between compartments

v1.3 models inter-compartment diffusion of four species. fast ≈ 1 day equilibration; slow ≈ 10 days; off = v1.2 behaviour.
