Overview

Engineering reference data for Foods Materials Bulk Density in food bio.

Key Formulas

pH

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

Measure of acidity in food.

Water Activity

$a_w = \frac{P}{P_0}$

Ratio of vapor pressure of food to pure water.

Thermal Death Time

$\log\frac{N_0}{N} = \frac{t}{D}$

Microbial reduction during heating.

Q10 Temperature Coefficient

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

Rate change per 10°C temperature increase.
