the water contents vary from fresh broccoli with 90% water content to almost complete dry broccoli with 10% water content. The water content values are related to the aw values (partial vapor pressure of water in a substance divided by the standard state partial vapor pressure of water) in a non-linear relationship that is the moisture isotherm curve. Highest activity at 70°C with 31% water content, overview | Brassica oleracea |
