Overview

Engineering reference data for Bio Mass Energy in food bio.

Key Formulas

pH

pH=log10[H+]pH = -\log_{10}[H^+]

Measure of acidity in food.

Water Activity

aw=PP0a_w = \frac{P}{P_0}

Ratio of vapor pressure of food to pure water.

Thermal Death Time

logN0N=tD\log\frac{N_0}{N} = \frac{t}{D}

Microbial reduction during heating.

Q10 Temperature Coefficient

Q10=(k2k1)10/(T2T1)Q_{10} = \left(\frac{k_2}{k_1}\right)^{10/(T_2-T_1)}

Rate change per 10°C temperature increase.
