Pearson correlation tests of physical properties, proportion of wall material, and bacterial count changes under bile salts.

Correlation	Pearson Correlation Coefficient	p-Value
A/B and pH	0.937	0.002
A/B and viscosity	0.915	0.004
B/A and conductivity	0.916	0.004
B/A and pH	−0.764	0.045
B/A and viscosity	−0.858	0.013
B/A and bacterial cycles change under bile salts	−0.830	0.021
Conductivity and bacterial cycles change under bile salts	−0.953	0.001

Correlation is significant at the 0.05 level. Viscosity (mPa s⁻¹), conductivity (mS cm⁻¹), bacterial cycle change (log CFU/mL). A: Mass fraction of gelatin, B: Mass fraction of culture with grown bacteria.
